http://www.mountvernonaviationexpo.com – REV ultralight trike, from Evolution Trikes home of the REVO! Taking a look around Sun N Fun I came across the folks from REVO who produce one of the finest and boldest looking weight shift control light sport aircraft in the world.

The REVO was desgined by Larry Mednick and his manufactured in the U.S. Larry and his staff have been on the leading edge of Trike technology for years and have introduced a number of innovative ideas to their products.

This year at Paradise City they once again proved that they are leaders not followers, with the introduction of the REV which won Grand Champion Ultralight at Sun N Fun! The REV (by REVO) is a single seat part 103 legal trike, that has a number of unique features.

But the most interesting is that it can go from flying to be folded ready to roll into a trailer by one person in as little at six minutes, with no special tools, and without breaking your back! And then do the same to go back flying. It is so simple that an eight year old could do it and did!

When folded it can be moved easily on the plug in "dolly cart". The mast used on the REV is a "complete triangulated solid structure as does not fold." When folded the wheels and suspension act as a counter balance for the trike, which means that to lifting the trike only requires a 40 lbs. lifting force to start and then becomes weightless as the unit is lifted.

Larry took the time to demonstrate how the trike goes from trailer to flying condition, using the unit on display. While understanding that Larry knew exactly how and what he was doing, on video it took him less than five minutes to do!

After Larry had removed the wing supports used for storage, and the "wing booties", he simply pushed the single surfaced wing forward, (single surface for easy of set up), which unfolded it. He then installed the battens which had small bendable tips that allowed easy installation.

Larry indicated that the single surface wing "has little haul back tension, which is one of the problems if you were using a high performance wing." The REV also uses few battens which again makes for an easier and faster set up.
During the procedure he stopped several times to demonstrate points such as the effort needed to start the lift, and how when the weight started to transfer their was indeed no effort required to lift anything!

The REV is designed to fly in the "low 40 mph range, with a top speed in the high 50's." The reason because the REV does not have or use a windshield. After installation of the battens Larry then pulled on a strap in the center of the wing and locked it in place which set the "haul back tension."

He then clipped in the "flip tips" to secure the battens, pulled what looked like a compression strut back into place and secured it "which supports the trailing edge of the wing for pitch stability". And locked in the washout strut at the end of the wing, with the last thing, he then installed the specially designed tip batten which has a spring loaded center that folds and then, locks into place the wing was finished.

He then unclipped the front section of the trike from where locks into the frame. He then installed the nose cone center panel of the wing. He then grabbed the control bar, with no effort at all lifted it and then let go and the unit sat there, weightless with the control bar at chest level. (If 40 lbs is still to much effort an extension handle can be plugged in to give even more leverage.)

He then removed two "speed pins" grabbed the front wheel suspension system and plugged it in and then reinstalled the pins. All the while with the trike sitting effortlessly on its storage cart!

He then reinstalled the throttle cable onto the nosewheel throttle assembly. Then one plug is used to disconnect and reconnect all of the electrical system. Two pins then removed from the control bar, which releases it, and three pins are removed from the dolly where it is connected to the airframe, which allows removal of the cart!

From start to finish on video just over 5 minutes.
