I am finding it difficult to find parts for the HDX500. I need an one-way bearing and new 140T gears.

I email helidirect but they haven't replied. The question I asked was whether the HCS500 gears, bearings etc are compatible. Anyone here know the answer to that question?

I found xmseller on ebay but they seem only to have the 94T gears.

I've got a brand new 140t, main hub, and one way bearing with sleeve already assembled. Along with a bag full of HDX parts. If you're interested in the other parts I can list out all the parts for you. I'll sell at 50% of HD's price

I have a 3DX500 (Lepton style) and a HDX500 (plastic head broken on a hard landing replaced by metal).
The 3DX flys with 3S and 1250Kv Scorpion motor
The HDX flys with 4S and 1000 kV Scorpion.

It is the HDX500SAH (H=Hitec mini servos).
I have the SAS version (S=Standard servos).
