Nitro engine starter
thingiverse
I've got a sweet nitro engine starter to share with you, and I'm printing it right now without any support needed. Make sure your motor has an M5 axle in place because you'll need to tighten two nuts together just as you see in this video: https://www.youtube.com/watch?v=516kRSQtDNk. If that's not the case, you might end up unscrewing the nut instead. Don't worry; I've got you covered with one CW and one CCW screw, though I'm pretty sure all nitro engines run CCW. To get started on the starter part, grab an M6 hex bolt that's at least 30mm long – that's all you'll need.
