Mark Trent and just built 2 of those they are fun nice change from the 40%ers....
All Futaba buget servos and a DA 50. Mine has a straight pipe and Mark has a Bennett muff. Great planes tons of fun. Make sure you check the retract mounts and reinforce them with some epoxy and micro Balllons. the plates are not glued in well. test fit and test fit retracts in wings and everything else just follow instructions. I used du bro hinges on rudder and elevator. CA hinges have a habbit of comming out over 120 mph. Robart on wings and flaps.
Good luck
Jason
