Yeah, that would be my guess.

I've been running on and off with a front gear diff indoors at Horsham packed with 500K, and the front-end feels consistent from the beginning of the run to the end.

Use an engineering putty rather than cleaning putty and you won't have any issues with consistency.

Motor Fan Position: Which method have you guys found to be most effective, to have the fan in front of the motor (next to ESC) blowing air onto the motor, or behind the motor blowing air onto or away from the motor?

Most layouts I've seen have the fan behind the motor, blowing air on the motor.

That is how I currently have my T3'12 setup.

I've been thinking that aerodynamically it would be most effective in front blowing air onto the motor/heatsink as the car is moving forward with air being induced into the fan from under the body making the fan turn even faster for more air. I would seem that the motor would be even cooler by at least 3 or more degrees.

I run a short servo on my '12 and am able to fit a SPR fan in front of the motor and still have room to mesh a full range of pinions.

I don't like running the fan between the ESC and motor because I always feel like it's going to pull the heat from the ESC and push it at the motor...just doesn't seem right. Many times there's not much room behind the fan to pick up air as well. In back, I think you're getting a cleaner and cooler air source.

Yea me too. I hate the spool front gear diff packed with thick oil is the future.

I could never keep ECS's in my 11 before gear diff's. Fitted a gear diff in my 12 in the front with 300k and never looked back. Even run it outdoors the ECS's last and don't wear that much.

Defo a game changer for me.

Be carefull.

Don't get to hung up on the length of the shocks. Just make sure the ball is not bound up as winding the shock end in too far will bind it up. Find a good position for the shock end and match the rest of the shocks to that.
Make sure the balls all move freely in the shock ends. This is very important.
