Flying the SeaRey LSX

By J. DOUGLAS HINTON

In the bright new world of Light-Sport Aircraft, a dowager — defined as a dignified, elder lady — lurks: Progressive Aerodyne’s SeaRey LSX.

Why “dowager” you ask? A little history: Back in the 1970s, the Richter family designed and developed a number of amphibious seaplanes, the most notable of which was the Buccaneer family of models. After selling the company in 1992, the Richters — father Wayne and son Kerry— plus Paige Lynette formed a new entity, based in Orlando, Fla., they called Progressive Aerodyne for the express purpose of designing a brand new amphibian they named the SeaRey, a two-place, high-wing, pusher prop, kit-built model that enjoyed immediate popularity.

Inflight3To date, more than 600 kits have been delivered all over the world, with the amphib represented by more than a dozen domestic and six foreign dealers.

Though Progressive Aerodyne still sells kits, the “dowager” part came in when the company certified the SeaRey LSX to LSA standards in 2010. Since then, President Kerry Richter estimates 65% to 70% of SeaReys sold are the LSX model. Of the more than 100 LSA models on the market, the SeaRey can claim it’s been around, in one dress or another, a lot longer than most — if not all — of them.

Almost three years ago, Progressive Aerodyne accepted an attractive offer from Tavares, Fla., a town about 35 miles northwest of Orlando that bills itself as “Seaplane City,” and moved its entire operation to the shores of Lake Idamere, where the company has ramp access to the water for testing and customer demos.

FromBehindThe SeaRey LSX “Elite” resembles earlier models but with some significant improvements. Vortex generators have been added to the upper wing leading edge, which replace cuffs and make the aircraft virtually spin-resistant. The horizontal stabilizers have been canted upwards to keep the tail out of the water weeds and provide greater stability. The standard engine package has become the Rotax turbocharged 914 of 115 hp.

The list continues: Glass cockpit; gap seals on the flaps that offer a 7 mph lower stall speed; electric landing gear extension/retraction standard with steerable tail wheel; an Ivo tri-bladed prop. Some of the more popular features include electric flaps, deluxe seat upgrade, oil cooler kit, ABS instrument panel, baggage compartment kit, plus nav and strobe lights.

panelGross weight has been increased to the LSA-approved 1,430 pounds for amphibians. The leading edges of the wing are swept back with a straight trailing edge. And suspended from aluminum struts are plastic floats on either wing. The structure of the aircraft is mainly aluminum with a carbon fiber hull (fiberglass for the “Sport” model) and fabric-covered control surfaces. An engine cowling is available, mainly for looks, as it doesn’t reduce drag significantly.

This is not a business airplane, though some may use it as such for relatively short flights. It’s a fun airplane. With a cruising speed of approximately 100 mph, it will not set your hair on fire. But it has an endurance of about five hours and amazing takeoff and landing performance, land or water of about 400 feet, making some of the smallest lakes or landing strips accessible.

It has a roomy cabin, even accommodating a couple of big guys without touching elbows. Visibility is superb to the front, sides and down and the individual canopies can be independently slid back in flight. And stability is superb. Takeoffs and landings can even be made without touching the control stick. Baggage, totaling about 80 pounds, can be accommodated behind the front seats and in a small nose compartment.

Getting Airborne

It was a beautiful, sunny day with a little wind to ruffle the water as Kerry Richter and I approached the demonstrator, perched on the ramp outside the main hangar. Kerry would do most of the flying while I observed and made notes. The walkaround is fairly standard with a few exceptions.

One is to check for water in the hull, which can be rectified by use of the bilge pump. And if the airplane hasn’t been flown in a couple of weeks, it’s a good idea to pull the propeller through a few times (mags OFF please!) to get oil to the cylinders, which may have siphoned into the sump. A short stepladder is useful for inspecting the engine area (oil, coolant level, air filters, etc). And if you anticipate docking, have a paddle and a throwing rope aboard.

CircleClimbing into the cockpit is easy. One foot on the tire, step onto the seat, other leg in and slide forward onto the floor, then strap in with the waist and shoulder harness. The brakes and throttle are mounted behind each other on the center console. The aircraft is steered by the rudder on land or water, not the brakes. Time to aviate…

Kerry pulled out the choke, mags on and hit the starter. We were in business. As we waited for the temperatures to visit the green, I asked him what the maximum sea state would be for the SeaRey.

“We’ve landed it in 3 foot seas,” he responded, “but we recommend a foot or below unless it’s an emergency. There’s also the argument should one take off with the canopy open or closed on the premise that if there’s a problem on a water takeoff or landing, egress from an open cockpit is easier. Your choice…” We kept ours closed.

With a mag check before entering the lake, we taxied down a ramp into the water and turned into the wind, lowering 20° of flap and raising the landing gear while adjusting the elevator trim to full up. What happened next was truly astounding. With feet on the rudder pedals to steer the aircraft, Kerry applied full power without his hands on the stick. In seconds we were on the step and off the water in about 375 feet and clocking 50 mph. Flaps up in stages and we were climbing out at 900 fpm. He then took the stick to adjust the climb, leveling at 2,000 feet.

Cruising at 75% power and 100 mph, Kerry then asked, “Want to see a full power stall?” This is not one of my favorite maneuvers, based on previous experiences in other aircraft. But hey! This is a pilot report, right? So I gave him a nod with a frozen grin. Full power, stick full back and we were off to see the angels. About 45 mph (I think, because my eyes were closed), it paid off. A judder, slight shaking and the nose dipped. No wing drop, no spin entry, it just mushed down as Kerry unrelentingly kept back pressure. After two or three of these mild oscillations, he released the stick and we were flying again.

“How about an accelerated stall?” he then asked. Before I could answer, he cranked the aircraft into a steep left turn and pulled the stick full back. Turbulence, but little loss of altitude and as soon as back pressure was released, we were back with the rest of the world. Clean and dirty stalls followed which are hardly worth mentioning. Mush straight ahead, release back pressure and you’re flying again.

Time for some water work, 180° turns, both downwind to upwind and vice versa. After alighting, Kerry mashed the left rudder and away we went with opposite aileron to keep the wings level. Then the opposite way. It was astounding how tight the turns were, verifying that the SeaRey could operate into and out of some pretty small ponds or lakes.

CloseUpBut my thrills were not over. Back at 2,000 feet, Kerry suddenly did a wingover and we were in a vertical dive toward the water. Just before we died, stick back and we were skimming the lake surface at about 10 feet or less, which continued for several miles. A true delight. The final act was a crosswind landing on the water, which presented no problems at all. As we taxied up the ramp toward the hangar, I reflected that this is some airplane. Sturdy, safe, a pleasure to fly and a joy to enjoy.

How Do I Buy One?

A $5,000 deposit is required, either for the kit or the ready to fly model, balance upon delivery. If you decide to build it yourself, a builder’s hotline is available for advice on any problems you may be having. Base price on the Sport model with the Rotax 912 ULS engine (100 hp) is $125,000 and for the Elite model with the Rotax 914 UL (turbocharged 115 hp) is $144,000.

    I have a home on the Santa Rosa Sound in the panhandle of FL. The protected salt water sound sure looks like it would be a lot of fun to operate from. I realize that salt water environments are corrosive, but are there effective treatments that can be applied? Do these planes have much experience regularity operating from calm salt water? Any other comments about this idea? When will the folding wings be available?

    Great article, pity about the “not so nice” Airmanship shown in the video. I am thinking of having a back of the hanger project.
    Is there someone who has made the mistakes that I could learn from?
    How long does it take to build one?
