I finished and maidened my FT mini Corsair this morning. Photos attached...including a couple of photos side-by-side with my Skyangel Corsair funfighter, which is about the same size. I put exactly the same power system in the FT mini Corsair as I use in the Skyangel -- i.e. a Turnigy Aerodrive D2826-6 2200kv, with a 30A ESC, a 3s/850 mAh LiPo, and a 6x4 prop.
I originally planned to put a motor only a little bigger than the motor recommended by Flitetest in my FT mini Corsair, but when I was about finished with the build and did a preliminary CG check with a 29-gram motor and an 18A ESC, it was way tail-heavy. So I figured, instead of putting dead weight in the nose, I would rather put a bigger motor. I expected it to come out a little nose-heavy with the 50-gram Turnigy motor and 30A ESC, but to my surprise it came out spot-on the recommended CG! Which is fortunate, because the design of this plane provides no room at all to move the battery around for CG. To secure the battery, I installed a velcro tiedown strap, securing the strap into slits I cut into the "O" shape in the top of the wing . The recommended skewer-stick battery-securing method would not work because the 850 mAh LiPos that I am using are too fat. The 30A ESC fit nicely on the panel above the power pod (photo).
The FT mini Corsair flew just fine, but with this power system, it seems that it could use a tad of downthrust (it has none built in), so after I got home I shimmed in a little "down," and I'll see how that goes next time. OTOH, the considerable amount of right-thrust built into the power pod on the plans was apparently just right (and identical to the Skyangel's right thrust angle, as can be seen in the last photo), since I experienced no torque issues during the two batteries that I flew. Peter was right about how careful you need to be with the elevator. Pull too much elevator, and the plane will do a snap. The ailerons on the other hand I found to be much too mild on the recommended throw (on the throw gauge included in the plans). Looking forward to more test flights on this cute little Corsair.
