Going back to stock
On second flight, after double checking tension. The belt came off the 3D printed front pulley while inverted mowing some flowers. This was a concerned when I saw no lip/guide on top of gear like stock. Ended up costing a set of main blades, and canopy damage

Works flawless, tail is locked in, perfect upgrade.
Had issues with my tail blowing out on my 470L. This tail pulley and belt was the perfect solution, no more tail blow outs, lower gain on gyro. And Amazed by the quality of the printed gear. I will continue to support KC3D!

Waste of money
The teeth on the gear is not deep enough so no matter how tight you make your belt it's still slips I have it tighter than I've ever had it before and the belt slips around the gear contact is my body and then you want to talk to you like you're stupid So now I'm leaving a review for the gear that is a waste of money your mouth is still with a slight tail blowout
