Hellfire conversion

Well, this is irritating. I switched out my bk 9920 for a quark 125 due to cogging from the bk. I also had to put my 8xl in since the 9xl took a dump. I'm currently geared 13/52 and I can run for about 5 minutes before the quark thermals. the motor is getting hot as well, but not much more than expected with a feigao. The ESC however, is roasting. I'm not sure the actual temp, but hot enough to shut it down.

I can't find anything binding in the drivetrain, and I can't really gear much lower than 13/52. I think moving to a smaller spur would be a bad idea.

I also have a problem with the spur skipping when I brake. It's fine in accelleration, but when braking, it will make a nice sound like the teeth on the spur are slipping against the pinion. I find the only plastic spur that works is kyosho ? I think there's nothing bigger than 46t in that, right ?

I really like the truck, but it seems I have a few bugs to work out.

We can feel your frustrations, but overall your experience will leave you with an increased knowledge that can help in future projects. At least you are learning what not to do. Fuegoes do seem to have there troubles due to high temps. Personally I don't think that they are worth the hassle. Spend the money and get a motor that you know will pay off, like the 1515/1Y Neu. We rarely see issues with them and the power delivery is awsome. It sounds like you are on the right track though. Are you having fun? That is the most important thing of all.
