Wear and tear

I will be ordering DD belts from this time forward. The Bando from TT wears out too fast. Lifetime is like maybe 3 hours of run time before it starts to click or crackle. The black DD belt has been run for over 2 hours with no slippage or wear and tear. The teeth seem to handle the abuse better.

I use the DD belts for my Outrage helis and get along great. The belts are cheap also.

Almost everything is still available in China

I was trying to find parts for the conversion of my E550 3 blades to regular 2-bladed FBL head. There is nowhere to find a dealer for the raptor line parts so I tried my luck by contacting TT Factory in Zhejiang, China directly. And the result is positive. The sales personnel told me that only 5 items in raptor line is deficient. So... we should be good for now.

Can you give us a link to the product line to buy parts for our Raptors?

Thank you!

Me too for the link.

This is a great thread Steve. The input from the other members is awesome as well!

Mine fall down, went BOOM!!

Update on using tail blades

I strongly suggest you use stock tail blades, do not use wide chord or extra larger blades. It forces the belt to hit the pulley harder and tears it up. This has happened to me three times, regardless of any belt tension.

The original frames with stock tail blades have not had any issues. I suspect using bigger/wider tail blades is the culprit.

This is now the 3rd frame I am going to have to toss the left side.

I can see the difference

Using stock tail blades and detuned pipe on OS50 engine is the way to go.

If you use MP2 or tuned pipe with larger than stock tail/wide chord tail blades, you are asking for trouble.

Frame/Belt can't handle the surge of power from a tuned engine all at once with a combination of 12 degrees of collective/9 degrees of cyclic.

Let ya guys know why your belts and pulley fails then chews up your frame.

THis is an awesome thread! I have 12 Raptors ranging from 30V1 to the 90 some scale some stock. This is a huge help! Thank you
