Can it be used with a 7.5 Turn mod motor, I know it doesnt say so on the instructions but thought i might have seen something regarding one of the mod boys running a 75??
I doubt it can handle a 7.5T unless you run no timing at all, limit the current and have a throttle finger made of butter.

I have only seen West London and Aldershot. Prefered Aldershot :-) I know the other tracks are even bigger but on my quest to find the maximum speed down the straight succeeded when my car backflipped WITHOUT hitting the bump :-)

Is it possible to have the files of your setup by mail ?
My email : forumgratte(at)sfr.fr

Thanx !
120 internal is no heat issue. You are close to a heat issue when you reach 139. so long, just don't bother.

Solder the fan wires to battery + and -. This will give you an extra 10-15

As for setup. There'S a guide for V13.1. Use that and adjust the timing from 0 to 12 depending on the track as matt already wrote.

It's much better to develope a personal setup rather than just copying one.

Thanks for the reply Martin

I certainly don't have a throttle finger made of butter lol, so I have managed to find a GM 90 that should do the job?

Thanks for your answer Martin.

Just one confirmation :
To apply 6 timing for example, "Fixed timing" = 6, "Max timing" = 7, "High speed timing checked".

Is it ok ?

Kerb, As Martin has said, personally I wouldn't see 120 ESC temp (in the software) as an issue. If it's below 140, then I'm happy - and if it's above 140, it will soon let you know!!

I don't know what the timing values actually mean - not sure if 6 actually means 6 degrees. Hence I just talk about actual timing values.

you have to have ticked Highspeed timing and highspeedtiming with switchpoint! you want a switchpoint

When does it flash? when it's running in idle state -> 0-boost program ofcourse

Are you running any timing on it ?

gearing for 8delta last year for me was ~43-45mm with no timing. 4 on frequency
