What motor to run?
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

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

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 |

There is the most probable reason for the lack of speed. I have a set of orion 3300 that were superb in their day and are nowhere near fast enough to keep up in 4WD these days so I keep them for practice.
I'd save for some new cells and motors ( a decent 12 is fine for bury in my opinion)

Gp3300 orgp3700 are fine if 2wd if you are doing 2wd and 4wd you may want to get something with a bit more umfth such as IB4200 or GP4300

Try before you buy.
Ask someone @ your local track if you can try a set of cells 1st. Most will help you. If they won't ask someone to run our motor. Do you run stick pack or side by side batteries? Do you charge, race, discharge, equalise them? What is the peak voltage your 2600's get to when charged ? What settings have you got in your ESC? (not sure how to do it ask someone to help) |

I'd try loaning a motor first, either a Checkpoint or an Orion. The Reedy KR's are very inforgiving and require lots of maintenance to keep then running well in my experience. I gave up on them some time ago as they just ate brushes, they were rapid, but only for 1, possibly 2 runs then they needed new brushes.
I reckon it's the KR that's letting the side down. Are you sure your speedo is hitting full power too ? Does the transmission run smooth without the motor in too, i.e no binding ? Andy. |

the esc is set up correctly, has already been checked. i charge, race, discharge yes, could do with a better charger but 1 step at a time. it runs smooth. I'm with you, the kr does eat brushes far two much, but even so it isn't on the pace with a new set of brushes. i try another motor, but the cells are looking to be the problem thanks guys

I picked up some really cheap GP3700's off ebay for £12 recently...i race at bury most weeks and its difficult to keep up with most of them as they are all top drivers with new and well maintained equipment.. alot of people will say its down to track knowledge and driving skills.
rubbish, if you havent got the lastest equipment then theres no chance in being competative. |

Thats a load of crap once i blew up my dominator evolution and i was racing t kiddy i used a covak exsplorer 2 with a 19t motor and some sanyo 3600 as i left my cells at home and i had a really good days racing and was just as competative as normal. And there area lot of drivers at our club who run basic equipment and there cars are just as quick.

Id disagree there. The A Finalists run the top gear because they can, they want that extra bit of performace. But having the top gear wont make you a top driver, neither will average equipment hold you back.#
