Pierre,

That's a nice conversion. My buddy and I just finished an XT8 conversion too. It was nice to find that Xray offers a nice assortment of gears to choose from. Right now, we're running the stock front and rear ring and pinion gears, but have gone to a 45/20 gearing on the spur and pinion. The motor is a Neu 1512/1.5y (1900kv) and the controller is Compro 16016 on 5S lipo. We're also running GRP Big Park 40 series tires on it. It's a good solid 50+ mph truck and is the fastest thing in truck class at the Saturday night drag races.

I love the XT8. I'm thinking about dumping my 8ight T and getting the XT8.

BTW, I see that you are using a converted clutchbell with the FD mounts. MegaMotors has Robinson Racing hardened steel pinions with extra long shanks on them. If you are fastening that clutchbell on the very end of the motor shaft, you might want to try one out.

Again, nice mod.
