tcmerf- I have tried the new bladder caps, and they seem to work very well. The only problem is that the caps are too tall to tighten all the way down, so they leak out of the top. To solve that you just file them down 1-2mm. I haven't yet used them in actual offorad condition, only on our carpet track, which has jumps and they worked well.

ok guys i ran the Co27 at socal. they didnt have the pro model so i got the non pro and put banzai serrated brushes and a purple and a red spring on it. in my first qualifer i geared it 16/84 in my T4 and it ran like a dog. i then remembered about gearing it high so i geared it 20/84. that was a huge mistake. the arm started to fall apart so i took it back to the shop and mike replaced it for free
i broke in the new brushes and geared it 18/84 and all i can say is WOW. the motor had enough torque clear anything on the trackk and then some (the track had a giant triple that people in sportsman couldnt even clear. on the straight the motor was fast as hell. i didnt do so well in qualifing cause of the gearing problems but in the main i was outrunning people like crazy. i had a couple of bad crashes that put me in 4th. then i messed up on the triple and a marshell ran and bent down to pick up my car then left it so he could marshall his dad
. i have to give the motor 9/10 just cause the instructions didnt say anything about offroad gearing

Finished building my FT T4. I have a GTB 6.5 geared 17/87 and it runs great! I just need to paint the body now.

I'm running a 16/87 on my GTB 5.5 (with HPI Yokohama tires) I'm gonna try 15/87.
What pinion does everyone think I should run on Masher2000 tires for some good ol' bashing?
Never tried running a 84 spur...

The CO27 is the real deal. It requires a different approach to gearing (which would be a good reason to include off-road recommendations in the instructions...) but once you hit the sweet spot, this motor is definitely next-level.

Has anybody else tried putting a 0.030 piece of lexan under the batteries?
BTW, after getting my new B4 dialed, my BK2 doesn't hold a candle

#1018

The B4 and T4 own the Bk2 and MF2.
