I had several questions regarding some old You Tube Videos of my CMP Corsair build. I converted them to electric. I no longer have the details of the power plant. The pictures should show how I did the conversion. It flew ok. Bad tendency to stall and snap. Crashed both of them. The ESM Corsair (also roughly 72" wingspan had much closer to scale outline and measurement and flew better. I also used the optional ESM electric retracts which were great. The CMP versions both had mechanical retracts which worked ok after fiddling a lot. I did convert to an air retract system shortly before destroying the last one. Hopefully the pics help out. If I were doing this over I would go with the ESM model and pop for the electric retracts.

Here are the parts I've got from the crashed Habu. L wing, L & R H. Stabs. The L H Stab has the control horn ripped out of the elevator. Also the rear anti rotation pin is missing and the CF stab to fuse joiner is broken. You may be able to fashion another one. The other stab and the wing look ok. I may have the servo bay covers somewhere. I suspect I just used the ones from this wing with the servos intact on the new plane. I'll check and let you know.

Todd requested we all post pics of ourselves on our blogs. As you can see my blog has been quite neglected lately. Maybe this post will make it feel better. This is me with my Pilot One 1/4 scale Waco YKS-6. (Electric powered - of course.)

This is the big brother to the UFO Wild Wing. 48" wingspan. Flying weight about 32 oz. I am flying this one with a HET Typhoon 4W motor, APC 6x4 speed prop, and a pair of Common Sense 1650 (8c) 3s packs. Amp draw at WOT is about 25. Previous version radared at 78 MPH, but speed was severely limited by wing flap. This one has top and bottom CF spars as well as glass reinforcement of leading and trailing edges and the center section of the wing. (after the Chris Klick "Riteway"). It is much much stiffer with only 1/2 oz. in weight gain. I haven't had a chance to radar this one, but it flies great in combat.

This is a Steve Shumate design that I have been flying for about a year. The front third of the airplane is mostly glue d/t the occaisional crash. It is a fun plane to fly. Powered by a Hyperion Y-22S 6000kv motor pushing a Wemo microfan with Hyperion 1200 20c 3s batts. Radared at 65 MPH. Very sensitive around the roll axis. It has nearly reached the end of it's life. I will likely build another to house the mechanicals and electronics as soon as it gives up the ghost.

When I saw this on RCGroups I knew I had to have one. I had to order it from Taiwan. It's a bit smaller than the GWS kit (42" vs 48" wingspan), it ends up being more expensive since the GWS kit includes brushless motors, but it looks more detailed and scale-like to me. I covered mine with silkspan and poly-acrylic, then airbrushed the colors on. It has two BP-21 motors with two 20 amp ESC's feed from one TP 2100 3s battery. The maiden flight was marred by one motor detaching from the mount and acting as a large airbrake. Extensive repairs have been completed and she is ready to fly again.

This is a sweet looking and sweet flying plane. We have had as many of four of these up at the same time in our group. Mine still flies great, even though it picked up some extra weight after some fairly extensive repairs to the nose. I recovered from a flat spin about 2 feet below an asphalt playground.

After going through a few iterations of design, we came up with this plane as a small space, 3D capable plane. It's actually quite fun to fly, but not at all stable. It is made of sliced EPP foama and is durable, but due to the constant control input needed it would not be a very good trainer.

Our club had been flying this wing for some time, and calling it the Wild Wing, for some time before the same name was used on a commercial product. We now call ours the UFO Wild Wing to differentiate it. UFO - UtahFlyers.Org
I think this is my 5th one. Powered by a Razor 400, TP 1320 3s Prolites it was our primary combat airplane until many of us switched to a larger version. It is still a kick to fly.

This little plane flies on a 40mm GWS fan powered by a Medusa 12mm motor and TP 730 3s batteries. Kind of on the back shelf right now because I stole the receiver to use in another project.

Originally flown for nearly two years on HiMax 2025-4200 with gearbox. Covered with 3/4 oz fiberglass and PolyAcrylic then airbrushed. Currently awaiting a new cowl and motor after a recent mishap. Flies very nice. Only bad tendancy is to snap roll to the left with hard up elevator.
