UNTESTED - this model, once properly balanced should fly quite well on an 18mm D.could even work on a C6-3.but I've not had the chance to test fly it yet.
Requires
Paperclip or thin piano wire for motor retention Notes
Because of the fin spread a special launch stand is offered. I suspect it won't suffer too much damage from a launch but keep an eye on this. I printed mine with Polycarbinate filament. It may need a heat deflector.
Added a shorter adapter for the X-20 just because, m'kay? Fusion 360 file
