Anyone have experience with a LRP 4-star motor with the GTB? Profile? Gearing?

I'm amazed nobody is talking about the 3.5r motor?

Anyone race it? It must be crazy? Equivalent to a 5 or 6 turn brushed mod? I know Craig Drescher and someone else ran them in the A-mains at the worlds but both had thermal cut out - hopefully I dont have that problem in the UK when I get mine.

Also, is it possible to just replace the rotor in my 4.5r velociti motor to make it a 3.5r? Or as the windings are in the actual can would I need the entire motor?

The 4.5r has been proven to be the sameish speed as a good 7x1, at the recent Scottish GP (www.sdrcc.co.uk) Team Associated's Alan Bickerstaff beat Yokomo's Olly Jefferies with one in one of the A finals.

Unfortunately, the new sintered rotor does not turn a 4.5 into a 3.5 (Wow, I'd be on it in a flash if it could!)

The new rootr has better heat resistance and gives greater power as far as i know. More torque is available with the new rotor (stronger magnet..)

The 3.5 refers to the motor windings inside the can. So, it's a completely new motor really.

Hopefully the sintered rotor will fix the braking probalem that some are having.

The new rotor helps a lot. Braking is more crisp, and the whole system runs a LOT cooler.
The powerband is different as well. We have found that the motor needs a little more gear to get the proper top end. In the end, the car feels like it has more bottom end and more top end, all with better brakes and lower operating temperatures!
We've also been playing around with slightly lower drag brake settings, because the new rotor has much more "compression" to it.

That's good to know. My arm is on the way and hopefully I can get some good testing done this weekend.

How much more gear does the motor need?
