I am building one of these now using the 14+ lb WREN kit turbine. I am mounting the elevator servos on the stab for very short pushrods and no flutter problems! Also added flap/airbrakes under the wings between the booms and the fuse. It goes together very well and has no big building challenges due to the nice plans. There is enough room to add a front canard like the new "rookie" ( hint) . As a backup, I'm having a kit laser cut" by PRECISION CUT KITS in N.J. This means that since they now have the plans "scanned" into their system, that anyone can call then and get a kit cut ( another hint). Building one of these does require a LOT of cutting on a small band or vibratory saw! but once the cut is done, building isn't too bad
