RC Helicopter Training Gear

thingiverse

I always get butterflies when taking a new model out for first flight. I built an Align Trex 470LM helicopter and installed a CC3D Atom to use as the FBL controller/gyro. Having never tried this combo (CC3D is not the first....or even fifth choice by most heli pilots....more setup work than a Beastx, Ikon, K/V-bar, ZYX etc), I decided it might be prudent to put a training gear on it, since it's an angry Tasmanian Devil. If it tips on take off or landing before I can trim the PID's, expo's or tail, I'll be pretty bummed. I had a few 1/4" dowels doing nothing, so I grabbed them up and went into Fusion 360 to draw up the parts. You'll need 4x - 1/4" x 18" dowels, 4x - zip ties, 4x - ball ends and 1x - coupler. It should add some margin of saftey to 300-500 size helis until you get the feel for it. Be sure to place it so it's as close to centered under the main shaft as possible for balance. If you need a set with different sized holes (like for 5mm, 6mm or 8mm carbon fiber rods) just ask. It's quick and easy.
