Nice design! Is it flybarless? How is the electronics setup to control that motor?

Yeah the heli is flybarless. The motor is powered by a brushless ESC flashed with simonk firmware (improves responsiveness of ESC). The ESC is then controlled by plugging the signal cable into the rudder channel of the FBL unit, and adjusting the midpoint and gains accordingly. Its easier to achieve using Arducopter with Pixhawk, but I have had very good success using MSH Brain as well.

Ohh, that makes sense. What KV motor rating do you recommend for a 450 size? I currently have several 450 size helis built and one is specifically for FPV, so I might try out this tail conversion. I run a pretty standard headspeed, around 2800-3100 RPM.

I used a 1900kv motor, 85w on 3s with that headspeed. Had OK hold for smooth circuits, but no good for 3D. Since you are doing FPV it should be OK.

I also used a 5x5 prop, which worked a lot better than 6x4 because it had less inertia and responds more quickly

Yeah, the weak rudder in one direction might be problematic for 3D stuff, but definitely should be fine for my mild type FPV flying. Good to know it plays nice with the MSH, I am thinking of setting it up on that as well. Thanks for all this info and parts recommendation!

edit: btw, I just realize i have some of your other designs in my collection, lol. Good stuff man!

Cheers man!

Great idea. Maybe with this in mind i would be able to design a printable heli with a possible minimum of non-printed parts. Can you tell me what motor do you use? Thx!
