Air-Cam isn’t a Light-Sport Aircraft because it has two engines. OK, it’s also a shade heavy but if Air-Cam could, it would be a LSA. Certainly it’s “light” and “sport” compared to most twins. Regardless, it’s a favorite of all the airplanes I’ve flown so I’m pleased to see its rapid progress under the leadership of Phil Lockwood, the original developer. *** The latest accomplishment is a factory-authorized amphibious float system from Montana Floats that includes all mounting hardware. As though it needed any more power — Air-Cam is the only multiengine airplane I’ve flown that can launch with one engine — the twin pusher can now be equipped with two Rotax 914 Turbos. Combined with the extra power (230 hp total), Air-Cam can be fitted with a constant speed reverse pitch prop system ideal for float-equipped Air-Cams. A new rigid mount can now accommodate High Definition video cameras…it is, after all, the Air-CAM.

-- - USAAirCam, Drifter… Dust Settles; We Have a Winner!
Among all airplanes I’ve flown the AirCam may be the most fascinating. This superlative twin-engine “ultralight” offers flying in a way few (or no) other airplanes can. (I earned my multi-engine rating in an AirCam.) Given my interest, I’ve followed the efforts by owner Antonio Leza to sell the operation. Over the last few years several would-be buyers came and went. No deal happened. Last fall I SPLOGged that Sebring businessman Shawn Okun appeared to have it sewn up. Again, no deal. *** But that’s over now. The dust has settled and AirCam is headed back to someone I consider its “rightful owner:” Phil Lockwood. This time the sale is for real and includes all design rights, tooling, jigs, and inventory for the AirCam and Drifter. Phil has a long history with both designs; he knows each intimately. *** Phil and wife Tish have worked hard to build an expanding enterpise at Sebring.
Lockwood to Help Educate A&Ps on Rotax Powerplants
A&P acceptance (or lack thereof) is a leading reason for Cessna’s decision to use the Continental O-200D in Skycatcher. Surveys through their Cessna Pilot Centers showed that a majority of FAA-licensed mechanics preferred an engine they already know. Most lack knowledge of the Rotax 9-series that powers the majority of the LSA fleet. And when an expert knows little about a new product, human nature compels him to resist. *** Trying to educate A&Ps on the best-selling LSA engine is one task of Rotax service center operator, Phil Lockwood. This winter, he’ll be giving hourlong presentations for A&Ps (and owners), trying to encourage to A&Ps to take a pair of two-day courses to bring them up to speed with the Austrian engines. *** Of 62 presently approved SLSA models, only 8 (13%) use another engine (Continental or Jabiru). Starting in 1973 with the ultralight market, Rotax has produced more than 125,000 aircraft engines.
Lockwood Delivering Drifter Kits; Air Cam Coming
When I first met Phil Lockwood, he was selling Drifters. That was more than 20 years ago. In that time the venerable Drifter ultralight went through several owners and many changes. A Drifter model even hailed from Australia for a time. But in a combined deal including the Air Cam — which Phil designed — all design rights, inventory, tooling, documentation returned home…to Lockwood enterprises (Read July 5, 2006 SPLOG). A 7,000 square-foot addition enlarges Lockwood’s facility to house the new activity. On a tour of this facility after the Sebring Expo I saw the stockpile of components that demanded a new building. Initially Phil expected only to supply Drifter parts to service about 1,000 aircraft flying around the globe. But early demand has staffers shipping a few kits even while they complete the factory. Lockwood also plans to deliver full Air Cam kits bringing this hugely delightful aircraft back to regular production.

Design
Cosmetic appearance, structural integrity, achievement of design goals, effectiveness of aerodynamics, ergonomics.
Pros - Classic design returns from the personnel who once staffed the original builder. This is not the heavier, wing-strutted Australian Drifter SB (see "Pilot's Report - Back Up From Down Under, the New Drifter SB," June '97 UF!); it retains the lightweight features that made the first Drifters popular. Very well-executed (even to the Rotax 912 installation). Placement of prop above the "pan" protects blades against water spray or other debris. More than 1,000 original Drifters are flying.
Cons - For pilots used to enclosures, the massive visibility and lack of structure surrounding the pilot may be disconcerting. The 912-powered aircraft in this report is not a Part 103 ultralight, and you can feel the weight. Noncommercial operators should probably stick with the 503 or 582. Older design may not appeal to some buyers.
Systems
Subsystems available to pilot such as: Flaps; Fuel sources; Electric start; In-air restart; Brakes; Engine controls; Navigations; Radio; (items covered may be optional).
Pros - The original Drifters used full-span ailerons and no flaps. Now they're available with a flap lever on the pilot's left. Altimeter, ASI, tach, EGT and Hobbs are standard (plus water temp on the 582). You can have electric start (though not on the single-seat Part 103 version). An HKS model will be offered soon. Brakes are employed with a squeeze lever on the joystick. Very easy refueling access.
Cons - Rotax 912-equipped Drifter adds unnecessary complexity (not to mention weight and cost) for most ultralight enthusiasts. Brakes are unidirectional offering no taxi accommodation.
Cockpit/Cabin
Instrumentation; Ergonomics of controls; Creature comforts; (items covered may be optional).
Pros - Ask for only one distinguishing quality of the Drifter cabin and familiar pilots should exclaim, "the view!" Four-point harness system is standard. Very good entry and exit for both seats. Good support from padded fiberglass seats. Tiny little windscreen blocks front seat from most windblast. All instruments easily readable.
Cons - Test aircraft had the rear seat rudder pedals rigged too close to the seat for full deflection (caused when the front seat was moved aft to accommodate floats and a large pilot; problem has been remedied). Rear seat can be pretty windy. Seats do not adjust easily. Aft seat cannot see front seat instruments easily.
Ground Handling
Taxi visibility; Steering; Turn radius; Shock absorption; Stance/Stability; Braking.
Pros - Tailwheel steering brings responsive ground maneuvering. Visibility (from the front) doesn't get any better; you can see the world from here. Spring steel gear legs offer good absorption even for the big 912 engine installation. Drifter's gear has proven itself in some of the toughest duty situations imaginable. Clearance is good and the prop well-protected from debris strikes.
Cons - Lack of differential brakes offers no extra steering potential. As on most aircraft, the brakes aren't particularly strong and are somewhat limited by your hand size and the ability to squeeze the lever. Aircraft is rather long; limited tight turning ability. Taildragger only; not all pilots feel comfortable with this gear setup.
Takeoff/Landing
Qualities; Efficiency; Ease; Comparative values.
Pros - Visibility from the front is absolutely superb; no excuse to miss anything in your path. Very rapid liftoff thanks to the 912 (but it is still quick even with a 503). Climb is awesome (1,000+ fpm) with the 912 and an adequate 500 fpm with the 503 even when two are aboard. Excellent crosswind capability. Good ground clearance. Flaps help steepen your approach.
Cons - The lack of visual bank and pitch references up front may be upsetting to some pilots used to lots of structure around them. Slips work but less effectively than an aircraft with covered fuselage. No other negatives.
Control
Quality and quantity for: Coordination; Authority; Pressures; Response; and Coupling.
Pros - Smooth, medium-light and powerful describes Drifter controls, yet it isn't too fast for novice pilots. Makes a good trainer. Linkages are tight with little looseness and little friction. Dutch rolls to medium bank angles went well on first effort. Steep turns are a joy with good turning stall characteristics. Precision turns to headings were child's play; any pilot should do well.
Cons - Due to the pilot's position forward of the wing, you must use other references to determine bank angles; some pilots will not care for this. Test plane rudder required slightly more effort than joystick, a slight disharmony (but one that is quickly learned) - see article references on this. With full-span ailerons (no flap option selected), adverse yaw is significant.
Performance
Climb; Glide; Sink; Cruise/stall/max speeds; Endurance; Range; Maneuverability.
Pros - Fuel economy is improved with the 912 (over the 582, though less so for the 503). Climb is strong with 81-hp 912 or 65-hp 582, adequate with the 50-hp 503 - HKS option may be the ideal compromise. Design does very well on floats and has seen many forms of work duty around the world. Good slow or low flying, especially if optional flaps are selected.
Cons - Speeds are modest; this isn't a long-range cross-country aircraft. Sink rate and glide are about average only (perhaps due to the lack of much enclosure). Rotax 582 model is quite a gas guzzler. While combination of performance is good, does not particularly shine in any one area.
Stability
Stall recovery and characteristics; Dampening; Spiral stability; Adverse yaw qualities.
Pros - Highly resistant to stall break; stays on heading and dips the nose only slightly whether power-on or -off. Pitch response to throttle movements is positive with little pitch change, perhaps as a big tail is close to the prop flow. Longitudinal stability is positive probably thanks to a longer wing to tail measurement.
Cons - Accelerated stalls at gross weight may fall toward a wing (though even this action is very mild). During power-on stalls, the nose gets very high with 912 engine. Nose-over on power increase is significant with 912; still exists with smaller powerplants.
Overall
Addresses the questions: "Will a buyer get what he/she expects to buy, and did the designer/builder achieve the chosen goal?"
Pros - Highly reliable pioneering design that still works very well in many applications. Use of presewn Dacron® wings greatly speeds construction and holds weight down (no weight-adding paint is needed). Cable-bracing remains one of the strongest ways to design an ultralight; it's light and low drag. Drifter has been certified in Japan, South Africa, Taiwan and Israel. Company reputation is among the very best.
Cons - Removable but not folding wings. Prices start at $12,985 for a single-seater and run to nearly $25,000 for the Super Drifter with Rotax 912 4-stroke engine. Older design may limit interested buyers at resale time. No enclosure offered or possible without major work; cold weather locations may have shorter flying season. Factory still spooling up production (though this won't take long).
The original Drifter was one of the ultralight industry’s flagship aircraft. Hatched by early entrepreneur Dennis Franklin, the Maxair Drifter enjoyed immense popularity. Several reasons exist for the Drifter’s popularity, and these were enough for Leza-Lockwood to offer a rebirth to the design. Déjà Vu All Over Again The Drifter is a tough design. The basic airframe consists of a lower boom tube that supports the pilot at the front and the large empennage at the rear with an engine midship. Because the separation is longer than some similar designs, the Drifter boasts a high level of stability that should please most pilots. Secured to the boom by a series of triangulated tubing structures, the wing is classic Klaus Hill. This prolific designer from the early ’80s died in an unfortunate accident many years ago, but not before putting his indelible mark all over ultralight aviation. Klaus is directly responsible for the wings of the Weedhopper, Hummer, Humbug and SuperFloater.

Design
Cosmetic appearance, structural integrity, achievement of design goals, effectiveness of aerodynamics, ergonomics.
Pros - The XL version of the Super Drifter adds refinement and features without disturbing the basics of this popular design (see details in article). More than 1,000 Drifters are reported flying. Top-of-the-line model of four Drifters produced. Leza AirCam has (wisely, in my opinion) retained cable bracing; it's lighter and lower drag than struts. 80-hp Rotax 912 installation was well executed.
Cons - Not all pilots love the idea of sitting out on the end of a boom; if you don't like it, you'll know right away. Some pilots will regard the Drifter as a dated, older design. Makes Part 103 exemption weight by a single pound.
Systems
Subsystems available to pilot such as: Flaps; Fuel sources; Electric start; In-air restart; Brakes; Engine controls; Navigations; Radio; (items covered may be optional).
Pros - Excellent flap system, both effective in use and easy to deploy. Lever is alongside pilot's thigh and comfortably reached like a center car emergency brake lever. The Super Drifter XL is superbly equipped (for a price, of course). Stick-mounted, mini-hydraulic brake system is surprisingly powerful. Open cockpit style eases refueling (and no interior fumes!). Engine access is excellent.
Cons - All the features add to the price and the big Rotax 912 4-stroke, 4-cylinder engine seems like overkill on an ultralight that flies well on a 50-hp Rotax 503. No instruments were installed for the rear seat instructor. But you can carry any system you can afford; no other negatives.
Cockpit/Cabin
Instrumentation; Ergonomics of controls; Creature comforts; (items covered may be optional).
Pros - Four-point seat belts front and rear, especially appreciated in such a sit-on-the-end-of-a-pole cockpit. If you like wide-open visibility, the Drifter is king (excepting maybe only the AirCam, which is a grown-up Drifter at heart). Full instrument panel arranged in an efficient T-panel. Entry to both seats is reasonable, but the aft seat is especially easy for a tandem design. Seats are quite comfortable.
Cons - If you don't like the wide-open feel of ultralights, then you better stay in the back seat (though it solos from the front). Entry to the front seat might be improved with a step; a kit builder can add one. Rear seat occupant is subject to considerable wind buffet. Seats don't adjust in flight. No rear instruments as an instructor may want.
Ground Handling
Taxi visibility; Steering; Turn radius; Shock absorption; Stance/Stability; Braking.
Pros - Mini-hydraulic system made for quite powerful brakes. Excellent visibility from the front seat to scan for traffic during takeoff| or any time. Spring steel gear offered good shock absorption even with the heavier Rotax 912 engine and two occupants. Ground clearance is generous. Prop quite well protected from runway debris.
Cons - Tailwheel action seemed a little sensitive at first though it caused no difficulties; a beginner may experience some challenges in crosswinds. Suspension is limited to gear leg flex and tire inflation. No differential brakes though they're hardly needed. A slight deck angle plus long coupling means the Drifter can be ground looped if you're slow on the rudder pedals.
Takeoff/Landing
Qualities; Efficiency; Ease; Comparative values.
Pros - Low landing approach speeds (40 mph) can be used with adequate margin. Slips proved surprisingly effective given the small side area. Flaps are highly efficient and easily deployed. Visibility is unparalleled in ultralight aviation. Good crosswind capability thanks to responsive controls. Climb is superb with the 80-horse Rotax 912. Short ground roll.
Cons - Though the Drifter XL exhibited very good sink rate - especially for a more heavily loaded wing - it seemed to run out of energy in ground effect; I had three landings that bounced more than I'd like. Some pilots will feel overly exposed on landings. Lack of lateral references in front seat is disconcerting to pilots used to enclosures.
Control
Quality and quantity for: Coordination; Authority; Pressures; Response; and Coupling.
Pros - Controls offer enough authority to deal with fairly strong crosswinds. Medium-fast response help make the Drifter XL a good trainer. Controls showed little slop and had reasonable pressures. Steep turns proved very straightforward; the Drifter XL holds the turn easily. Precision turn skills are quickly acquired.
Cons - No one would call the roll rate fast (though authority makes up for this). My Dutch roll exercises worked well but only to shallower angles. If you use full power on takeoff you may run out of compensating rudder range (another sign to me that the Rotax 912 is too much engine for the Drifter). Lack of visual references in front seat may confound some pilots' effort to learn the handling.
Performance
Climb; Glide; Sink; Cruise/stall/max speeds; Endurance; Range; Maneuverability.
Pros - Despite significantly more power, the 80-hp Rotax 912 has better fuel economy than the lower powered 66-hp Rotax 582. Climb is breathtaking with the 80 horses pushing you. Robust airframe has survived challenging duties in many locations. Design has long proven itself on floats. Perhaps even aided by the big engine, the Super Drifter XL did very well at low-over-the-field flying; flies quite well with flaps deployed. Sink rate seemed excellent for a heavier ultralight.
Cons - Hard to fault the performance of this high-powered workhorse design, but the HKS 700E engine may prove a better choice (60 hp vs. 80 hp) for those who prefer 4-stroke operation. Not a particularly fast design, though the open cockpit wouldn't be very comfortable at fast speeds.
Stability
Stall recovery and characteristics; Dampening; Spiral stability; Adverse yaw qualities.
Pros - Power-off stalls broke but very predictably with fast, almost automatic recovery. Power-on stalls only discernible by a tail buffet. Accelerated stalls often dropped the high wing and leveled out quickly. Longitudinal recovery from level was fast and straightforward, no doubt due partly to a long coupled tail and generously sized tail feathers.
Cons - Typical high thrust line response lowers nose pronouncedly on power addition (opposite of certified aircraft). Nose gets extremely steep in full-power stall practice.
Overall
Addresses the questions: "Will a buyer get what he/she expects to buy, and did the designer/builder achieve the chosen goal?"
Pros - As luxury car makers might put it, the Super Drifter XL "has few options because all the right features come standard on this top-of-the-line model." Very tough airframe that has done heavy duty for years. Drifter models have been certified in several countries.
Cons - You'll pay a pretty penny to have the Super Drifter XL, which is so loaded with features that the options list is short; everything's already included. Lower priced/lower powered Drifter models are available and may be a better choice for many buyers. Company has been through ownership changes lately; more changes appear likely.
Considered by many to be a workhorse, the Super Drifter XL shows refinement and features that make it seem like a “luxury ultralight.” Leza AirCam, the newly renamed producer of this venerable ultralight, has equipped the top-of-the-line model with nearly every option in their price list. Conclusion: While it will cost you a bundle, you should be satisfied with this ultralight for many years. How is this Super Drifter XL different from the Super Drifter that I evaluated almost 3 years ago? According to Denny Franklin – yes, that same icon of the Maxair days when the Drifter was a youngster – the XL is a significant redesign of the original Super Drifter 912 flown in 1998.1 It has seen numerous changes to make the veteran design work better with the big 80-hp Rotax 912 situated at the rear of the wing. What’s New With the Super Drifter XL? The Super Drifter XL has an extended fuselage – meaning the boom tube and its fuselage “pan” – to position the front seat 5 inches further forward.
