Push control will cause the car to have added throttle when going to nuetral. Yes that would make your brakes feel odd or delayed.

We're testing new software right now that has some changes for brake performance, stay tuned.

But a good way of getting rid of the 'auto break' built into some motors (eg. LRP X12 13.5T).

Please please, also look into a modification to create more punch at low rev's

Hi folks,

I have a basic question about motor timing in Jason Schreffler's setup on the Tekin website.
His timing for the Duo , is 10 degrees . wondering why this is ?
Would it be for more bottom end, when the turbo isn't engaged ?

I'm running a Duo 17.5 with an RS pro. New to this speedy, so in trying to get some ideas before I run it. Mine is set at 0 on the motor at present. So it should run cooler until I get used to the extra power and my new chassis.

Fleety

Adding motor timing will give you more punch before the
timing kicks in

ie off the line or tight hairpins

motor timing was talked about a few pages ago,that just because motor timing is set to 0 some motors may make its most amount of torque with motor timing

what are you guys on about?

how can more motor timing = more torque ?

the most torque a motor makes is at minimal motor timing

Hi Gents,

Maybe someone can help me with an explanation and a solution to my problem,
I run a 13.5 SP V3 with a RS pro, i did the radio calibration and i found that 4 min into the race the car faded so badly that it alsmost needed a push just to make it over the line.
what do i need to look out for?

Thanking you in advance

you may be over timed or over geared post your full setup

Motors make the most torque at 0 rpm with the lowest timing. As the rpm incresases the timing required for the most torque actually increases as well. This is just like in gasoline 2-stroke engines where the exhaust ports determine "timing" and higher timing at higher rpm produces more torque.
