BUMP...

Steve,

Just got my brushless package, it is the #3010 GTB System with SS 10.5 motor box but it doesn't have a extra sticker on the box that says with "lipo cutoff". However, it does say in yellow words "Li-Po cut off circuitry" on the right beside the ESC picture.

Is that it?

Thanks.

Do you have your throttle trim turned up by chance?

If you do that can reduce the amount of effective drag brake you are getting.

Also, if you have the bonded rotor in your motor an upgrade to the sintered rotor will give you much better drag brakes.
thanks for the reply Steve
it is the new system can i adjust the trim on the stick to give me a little more like a auto brake?
thanks

Hi Steve.

I have just got my self #3010 GTB System with SS 10.5 motor, after reading the literature that came with it I notice the one labeled "Profile selection & proper gearing" states for the SS 10.5 to go 1 tooth higher than normally used on a 19 turn brush motor, but the information for the motor suggests to go 3 teeth lower. I normally run at around 6.5 / 6.8 Final drive with my brushed motor so can suggest which way I should go for a starting point.

Many thanks.

Steve,

Sorry for the confusion with all the literature!

with the 10.5 with sintered rotor I recommend starting out at a 5.5 FDR.

I originally posted this in another thread, but realized this is a better place to ask....

I've been racing my XXX-S locally with a GTB/13.5(bonded) setup. I had all the usual issues -- ran too hot until I geared down to around 6.2 FDR with rubber tires and finally got the temps down to around 150-160 (90+ F degree weather)...

SO - Tonight I replaced the rotor with a sintered rotor... (I've worked with brushed motors for 18 years or so, and I'm spoiled with having my Turbo Dyno 45 to allow me to test motors, etc.) When I first tested the converted motor (ONLY on the workbench so far) -- I thought I'd done something wrong... It sounded so SLOW compared to the way the bonded rotor sounded... Fully installed in the car, I realize it's working fine, but MAN! it sure is different! Before, the drag brakes (even manually applied brakes) were WEAK -- drag brake was almost unnoticable! NOW - ZAP! it appears to act almost like a brushed motor...

In reading about gearing recommendations, I always thought the sintered rotor versions "allowed" taller gearing -- now I am starting to think they MUST HAVE taller gearing to achieve the same speed...?

I'm guessing I will need to go from 6.2 FDR (bonded) to around 5.0 FDR (sintered) for our relatively small parking lot track with rubber tires...?

I won't get to track test until Sunday at the next HobbyTown races, so I want to make sure I'm understanding this right...?

Your thoughts?

I'm running 4.58 on my home track (big, 1/10th nitro track - it takes up 3.5 asphalt basketball courts). I ran recently at a smaller track (about a basketball court in size) & left the gearing at 4.58 for the 1st run thinking I'd be dropping pinions but it still had heaps of torque & was easily the fastest car in a straight line. At 4.58 I've never measured over 160deg F.

Steve ,

A while back I asked you the part number of the sintered rotor to put in the older 13.5 motors, and you told me # 5908. When putting it together last night I noticed that the sintered rotor is smaller dia. than the bonded rotor. Is this correct?
