Brushless Motor gear ratios

the only thing you would contemplate using a 3.5 on is a large scale track with stupid long straights! Not a small twisty indoor hall.

Rich Lowe said you drive a laser, if it's the ZX5 then i wouldn't be too confident it will handle a 3.5 if i were you!! i know, i race a ZX5.

i think the polite way of saying it is that you are masivley over geared at the moment which with a brushless will cause it to go a lot slower than what over gearing a brushed motor would

experience of most racers (myself included) is to possibly go from the recomended 14.1 down to 13.1 for uk tracks as the tyres are a slighly smaller diamiter and then adjust from there or in this case find the smallest pinion you have and put it on as if your gear guess is correct at a 10 tooth it obviously wont fit.

the gearing you have on at the moment will eventually lead to you wrecking your motor or speedo or possibly both so gear it down and belive it or not you will find your car will become a complete rocket ship meaning you wont need a 3.5. look at the national a finalists, most still use a 5.5 in 4wd and only ocasionally drop to a 4.5 if they really need horse power

I half wrote a reply to this poiting out the insanity of your suggestions, but then realised I can't be arsed anymore!

I know from experience that a 5.5 can be made quicker than a 9x1 prepped by Oscar Jansen, so unless you can prep motors better than him I think your 4.5 should be much better than your old 10 turn, therefore you must be doing something wrong, and probbly damaging your equipment.

But hey, thats what everyone else has said so why would you listen now?

Just out of interest how do you gear sensorless motors different to sensored, considering you said in the first post 'as i know zero about brushless.'

Yes I do, but LRP and Nosram are not sensorless so not worth reading.

I really do think you should take the advice you ask for or not bother wasting your time asking us when you have no intention of using it.

i was going to post but i think tom just about said it all really, and a dam sight politer than i ever could have after reading all the posts
