Buy 1 more space glow starter (perfer those can change battery)
Receiver battery use LiFe
Starter box battery use LiPo or LiFe (i use same 4s lipo as for 1/8)
Use 6.6v LiFe la, no need to recharge everytime before play, and battery has very long life... All my previous nimh are already dead but all my LiFe battery are still working very well
1. you have to move up the header pipe so it never touch the plastic even under vibration
2. the throttle knob can be turned downward so the throttle link can be in parallel to the servo motion
3. I think you inverted engine mount in the assemble and something wrong in the clutch/flywheel assemble.
4. The fuel intake nozzle need to be turned to proper position
