CHC, quick question, when you say gear up, you mean go down in tooth count? I'm curently running the 8XL on the mentioned 16\47 and it's quick, but not nearly as quick as I think it should be, based on some of the stats I see in these forums, if I rear gear, less teeth, I get less top end and I certainly don't want that. When I purchased the motor an 18 tooth pinion was suggested with the 47 tooth spur. Trying the 18 tooth first the can got blistering hot in virtually no time, backing down to the 16 helped A LOT, but also cut my top end off... Coming from nitro Savages, I wanted to build something that would hold its own, if not run passed, my still nitro burning budies :-) :-)
I've tried the 9920 out of my 9L truck just to be sure it wasn't the controller, still had the same issues, gets warm real fast and just isn't what it should be on the power curve. Don't get me wrong, it will back flip in its own footprint and moves out with some balls, but is still missing something on the top end.
I may snag the MGM, stick it on my current 8XL, play with gearing from there and see what happens. Worst case, I'm pretty commited to snagging a Lehner 1950 and just upgrading everything!!
I'd also be open to any gearing suggestions, what are you guys running on your 8XLs vs the weight of your trucks and 4s?? I didn't think 13 pounds was to bad for a fully converted Savage?? And I'm sure if if I look hard enough I may actully be able to lose another pound or so, but it would mean getting creative, lol...
Thanks guys!! Appreciate ALL the input on this!!
