Racing truck update. About 3 weeks ago it got really hot again, Always have heat issues on this truck. A 9 tooth pinion ran the best, bit its hard to get a 9 tooth to mesh up good with the dromida motor mount, and the only one I had got chewed up. It was running a 12 tooth when it got super hot. Anyway, the motor was junk, didnt want to move any more. So, being sick of it I sat on it a couple weeks, contemplated selling the damn thing, and then decided to try to put a bigger (physically bigger) motor in it.
I got a 2440, 6800kv 4 pole motor in it now. As a comparison, the hobby wing that was in it previously was a 2030 5200kv (I think they are 2 pole, cant seem to confirm this), and I have a 10 tooth pinion in it at the moment. I have a integy heat sink fan combo on order that will fit this new motor, hoping it shows up before race time this weekend.
Interesting thing, this thing got so hot so often, the chassis was actually slightly warped right where the motor mount bolts in. The motor would not sit straight, and you could see a distortion in that little groove where the mount sits. So, had to basically rebuild, all on a chassis from a parts truck. While I was at it, I added limiters to the shocks. As it sits in the pics, it cant physically get any taller than that. Shes a low rider lol... Hoping not too low, we shall see. And while I was at it, had to print a new box thing to hold all the electronics, my new thing is trying to make things that hold things in place so I dont have to use double sided tape lol
