any idea what kind of current to expect on a 2.5 on 2s lipo in a 1/12 pan car? i have a maxamps 2s 20c 3100 lipo that supposedly can handle about 100 amps surge/burst and was wondering if i went small enough in pinion if it would handle it.

Question for Randy etc at Tekin.

With regard to the weak brakes problem that a lot of people have expewrienced, including me;

It has bveen suggested by another person who has suffered to try setting the motor to forward & reverse, the reducing the brake/reverse endpoint of the transmitter down to a level that enables the speed control to try and engage reverse but so weakly that it actualls appears as strong brakes.

I.e, when my reverse side is set to 35%, if I hold the car off the ground and pull back on the stick I get the high pitch 'frequency' type of sound but no reverse movement.

My main question is, If I race with it like this using weak reverse as my brakes, will this cause any damage or overheating etc.

Have you checked your sensor cable? If the sensor cable come out or loses connection, the controller defaults to sensorless mode which has very weak breaks. The default setup for the controller is to run in hybrid mode with senored start and sensorless run and this also has very weak breaks compared to sensored mode. I would check this first. I had it happen a couple of race days ago, and it turned out that the sensor cable was just loose.

i have just come home from my local track , and i am quickest down the straight , the others were using the new GM120 and the Mamba max pro

i am not the best driver in the world but this speedo has some power in it , i was running an SPX last year with the GM 13.5 and i had gearing of around 4.5 to 4.7

now with the Tekin motor and speedo i am at 6.8 , and think i could go to 7.0 to gain some more punch out of the infield ,

GREAT SPEEDO THANKS TEKIN

just hope my driving is as good LOL

Or narrow your RPM range.

I would not reccomend using the reverse as brakes. I haven't tested it but I would expect higher motor temps and more battery usage.

We're working on new software right now and I'm confident you will like the results.

For the 4.5T setup: How big is the track? What's the application?

Even I'm not crazy enough to run a 2.5 in 12th let alone with 2 cell LiPo. You're not going to make time and I would bet that no matter how you gear the car it's going to draw too much current.

If for some strange reason 2 cell is legal for you I would recommend not running a motor lowe than about a 5.5 if you want to have any chance to make time and keep things from burning up.

Try 500 to 1000 rpm steps, and temp after 3 min.
Shouldn't heat it up if you don't go too crazy, will definitely add punch.
