Tron Belt Tensioner Assembly Complete - 5.5 Gemini/Orion

Don't waste your money on this for a Dnamic, It mounts too close to the forward tail clamp so it hits it with very little movement and you can't put the boom in if you tried since it doesn't allow the boom to slide far enough forward for the belt to not be too tight (with tail boom slid all of the way forward)! I tried to mount it backwards to see if I just didn't get it but then the spring was pushing the roller into the tail boom clamp... Who do I contact about a refund, Tron or Helidirect!?!? I would guess Tron is at fault really. The brand just starting to move up my list of comparable helis. I do love my Dnamic though and it does fly great without this upgrade. I guess I now know why they didn't show it mounted in a Dnamic!?!?

I did give it 2 stars since it does appear to be Tron quality for the other potential helis that it might fit but that is almost too generous since it doesn't work as advertised for me.
