This nitro engine starter is easy to print and prints without support. Your motor must have an m5 axle and you have to tighten 2 nuts together as you can see in the video. Otherwise you unscrew the nut. I have included one cw and one ccw even tho i think all nitro engines are ccw. For the starter part you need an m6 hex bolt 30+ mm long and that's all.

Hope you like it!
