Change the landing gear...invest in some carbon fiber landing gear. Drill out 2 new holes in the wing mount and use 1/4 20 nylon bolts with 2 new anchor nuts. Swap the rudder Servo to the elevator and vs vrs the elevator. Use a .61 two stroke or 91 four stroke. I'm using the saito 100 and it's lighter than a OS 91 four stroke.

Beautiful well made artf kit however the pushrod threaded ends do not seem to fit standard stock 2mm clevises due to incomatible threading and there are no metal clevises supplied even though it shows them on the pictorial instructions .Apart from this small problem the kit is very comprehensive and complete. cant wait to finish it and flight test it.

Very strange design having the wing bolt on the bottom with only one screw (had to bind the fuselage to get the wing screw in as wing doesn't seat well) for a supposed extreme 3D model, the wing don't fit right, servo mounts had to be modified to fit any standard servos, elevator design makes it hit the rudder on full down elevator when left rudder is used in combination. You have to cut the canopy out and glue it on, the cowl was poorly formed and is wavy on the one side. The landing gear mount is a heavy heavy chunk of aluminum that is way to heavy for any plane. I'm not sure this plane will ever get its maiden flight.
