controller advice for fastest car event

[Mattymaxx]

Hi there.

Im entering into the fastest r/c car challenge in march and ive got a specially modified rustler to equip with brushless.... i wont go into much detail but i need the help/advice with the setup...

Ive got a 7xl handy and a maxamps 6s 4000mah lipo....

Im torn between the quark 125b and the MGM 9032 car controller.

Yes the quark 125b is alot cheaper. but from what ive seen by searching this forum i can bring up 5-6 burned out 125b controller threads.. i dont want it smoking on me! :-(

Is it worth spending nearly £200 instead of £150 on a better controller...

Cheers
Matt.
