Less wheel spin will also up your runtime. I remember fighting the wheel spin beast on a simple 1/10 2wd truck on a winter indoor track. almost made my runtimes go up 30% just by correcting it.

when proline comes out with a real 1/5th scale track tire that may help wheel spin .plus when the track gets redone and watered in a few weeks and has traction that may help too.
im thinking a 16 pinion will still be plenty for for the straight.

update- i ran at same track but only used whatever throttle the track could take. tried to have very little wheel spin. maybe 1/2 on the straight.
i got 17 minutes run time instead of 12.
motor was max temp of 150F on telemtry and was 125 in the pits by temp gun a minute later.
batterys were much cooler .100f
center dif was 50 degrees cooler.
60 degrees out today instead of 70
still a 150 amp current limit and a 3.5 voltage cut off



dont freek out with the rpm i may have 2 pole instead of 4 pole in telemrtry.? just devide by 2

I would try 100k in the center, the truck seems to rotate very well naturally. You always have some throttle to make it do what you want if 100k is a little thick off throttle.

I want one of those trucks bad, don't hate but mine will have the 28.5cc reed motor in it though, I've seen a couple videos and that motor is nutty. The thing keeping me from getting one is no track for 1/5th around me to run it at.

I retired from RC, now life is all about guns and long range shooting.
