I'm assuming the answers to both is yes ...but don't like a assume
Also, do you have the numbers that a 13.5 should be reading?

Now what is really strange is he had never had a thermal problem with the regular rotor. I guess the question in all this is does the sintered rotor degrade and become easier to overheat like the stock rotor?
I have seen this in cars that are really bound up (tight) the driver has to compensate for the handling of his car and is hammering the throttle harder and breaking harder and later in the corners. If he frees up his car he will probably do better and his thermalling problem will ease.

I have a question about balancing the T2'007 US with the Novak brushless.
I have the following electronics in the car:
LRP Sphere Comp 07+cooling fan
Futaba Low Profile servo
Ko Receiver
Novak 13.5 + cooling fan
AMB personal trans

With IB4200WC battery I have to add a lot of lead to the battery side to get the car balanced. I end up around 1573g/55.5 (with foams) when I reach the balanced condition. When using LIPO I end up around 1535/54.2. The difference is because I can put lead under the pack and also to the side where the NIMH has the battery bars. It is still 4 ounces over the legal limit.

My question is what is better:
a, to have an unbalanced car which is on the legal limit or
b, balance the car and dont worry about the overweight (we are talking about ~140g/5ounces here)

Or is there a way to balance the T2 and have less overweight? Could you share some pictures of layouts which are working well...

I'm gonna get the ribbed endbell soon to decrease the overall weight of the motor but it is so close to the centerline of the car so it won't help much with the balance

I think a lot of people are struggling with this, especially those using BL motors. LiPo further exacerbates the problem. I've heard people say both ways are better, so I'm not clear what the answer is at this point.

I kind of wish there were a way to easily use LiPo but have it take up a lot less space. I'm pretty sure the cells are relatively small, but jammed into a larger case to fit into traditional battery slots. If they were made smaller, you could move your ESC and receiver to the battery side and have much better luck achieving proper balance.

I'm going to give the Type-R a try and see how it feels, the layout sees to exclude it from some of the issues with BL/LiPo we're seeing on normal chassis.

Thanks for the quick answer. I think with the LiPo its better though because you can put weight on the outer side so you need less to balance the car but this also increases the moment of inertia (I guess thats the right phrase).

I will never be so desperate that I buy a losi (joking)

I just switched from a front one-way to a spool. The temp. on my motor went from 110F to 165F geared at 5.01. Does this sound right?

Sounds like you might be scrubbing speed under load? or you might have to much drag brake dialed in.
