no faster with new motor
 

just changed my speed passion v3 10.5 motor for a speed passion mmm 10.5 motor in my rc12r5.1 12th car max motor timing on v3 was 10 degrees on the mmm its 20 degrees which i run last night i run the core rc speedo in blinky mode i thought the mmm would be quicker having the extra 10 degree motor timing but was a lap slower with the mmm has the v3 on the same track layout has the week before i also run the same roll out (gearing) any ideas ?

More mistakes in the hits? Did you run perfect?

You probably crashed more. Just because its a faster motor doesnt always mean you`ll gain laps, just crash quicker. More laps is gained by a consistant run. If you feel your going slow then its because you havnt crashed and will gain laps.
As they say going slow is faster round the track than crashing all the time and having to wait for marshalls

thanks guys for info i was taken out a few times by other drivers so could of be that plus tyres were worn abit

did you gear it up any higher,? the mmm series has more torque and thats were the extra speed will come from
