What motor to run?

[Iain07]

hi, im new to the forum (so sorry if i say something stupid)
i've been having trouble with the motor that i run in my B4, i have tried skimming and re'brushing it but the top end speed is still far to low for my local track. i have also increased the gearing, with no real look.
i was wondering what motors you run and would recomend (for running at bury metro)
thanks for any replies
ps. am runnig the reedy kr 12T double.

a 12t in 2wd shouldn't be a mile off the pace. if you have skimmed it and re-brushed it the only things left would be clean the bearings thoroughly and check the timing.
Could also be the high point settings on the speedo/transmitter?

if these don't resolve it you might have a more serious problem, ie the motor is knackered in some way.

12 turn motor should be fine as long as its been skimmed and brushed properly. and batts are in good nic, as this can affect speed also

hey up carl, do you still need to use my 3* btw? I could do with getting it back for the supercup - I will probably be ok without it if you need to use it still.

well im waiting on peter frpm castle models to get the right motor back of nosram but hope fully you should be ok jimmy thanks as well for the lone ill make sure u get a little treat when im up and running full steam with ma shop

im running 2600 orion cells, they'r fine in my mission. running the VX sport mrt esc. gearing, 81 spur gear and 23 pinion.
i was trying to aviod brushless as i dont trust myself and the price. i thing the motor itself might have been damaged in a crash .
otherwise im out of ideas

i have ran a 12x1 a few times and its nowhere near quick enough either. the only way to get away with a 12 turn is to have stupidly powerful cells and speedo. therefore ive gone brushless

[jimmy]

I have to say though if you gear right a 12 turn is QUICK. I ran it to 15th place at the recent York regional - and I skim about twice a year - my motors get no love at all.

So apart from the KR12T motor what batteries are you using, esc & what pinion spur do you have it on?
