Brushless Truggy Part 2

[Shark413]

lincpimp, yeah thats the flywheel I am using. Like I said I had to turn it down even with the bell so it would clear the brakes/diff mount. The portion of the flywheel that is normally used to start a nitro engine using a starter box is not needed and gets in the way when used in a brushless setup. I have a small lathe so I chucked it in there and just shaved off what I didn't need. I guess you could do the same using a drill and a file.

bluonyx, yes that is Hot Rod Hobbies. I am normally out there on Sunday's practicing/tuning my setups, with an occassional race squeezed in on Saturday. I was out there this past Sunday and Jimmy B. was having an on-road event so some of the expert nitro guys were there helping him out. Afterwards they came over to the dirt track and were driving their nitro buggies and they noticed me out there with my brushless buggy clearing the entire section in the picture above. They couldn't believe the brushless power/accelleration my buggy had and actually stopped to watch.

Update: Took the truggy out this weekend for some testing. The clutch worked great and really did smooth out the brutal brushless power delivery. It felt almost nitro like with a lot more snap, but it was kind of weird because there was no nitro noise. Unfortunetly about half way thru the day I again stripped the plastic spur after landing hard. Apparently the clutch does not offer as much slip in this situation as I had hoped. I had a back-up diff with a steel spur that I mounted in the truck. I ran the rest of the day with no futher issues. Wear on the steel gears was minimal at the end of the day. I am still concerned with the stress on the drivetrain (enough to rip 4 teeth off the spur) so I would have liked a little more give with the clutch system (guess I have to wait for the slipperential). I did like the way the clutch smooths out the power delivery. So I now I need to decide if I should run the clutch or go with a hardened pinion and eliminate some of the complexity/maintenance that comes with using the clutch setup. I think I will run it as is for a litte while longer then decide.
