This plane is a handful on the ground. You will want to move gear forward 1/4"-1/2". I left mine stock until they got ripped off. Left in stock position I had to taxi and take off with full up or plane would nose over. Moved it to front 1/4" and what a difference, works great. The more you move up the more stable it is on takeoff and taxi but will start to bounce real bad on landing.

I made a cowl from balsa and side mounted engine. make a ring to match spinner, glue to spinner back plate with CA and mount your engine. Then start gluing balsa back to firewall. Remove engine when there is enough pieces to keep cowl straight. Carve, plane and sand to shape. Make sure to leave enough room to remove engine.

If you want to 3D you'll need to add some rudder at least 3/4". Mine will hold a knife edge but won't knife edge loop.

Definitely use the two servo option

You'll have good fun with this plane.
