Is it right that the lower the turn the more torque you get and hence the less top speed? If thats so then surely the gearing needs to compliment the motor choice so as not to under or over balance the mix?

I think that makes sense?! Does it?

Lower turns = less torque more top speed

The best thing to do, is first figure out what class you want to run. If you want to run in your track's stock class, figure out what the motor limit is. Probably a 17.5 or a 13.5... they also might have limitations on whether or not you can run timing. If you plan on running mod and are at that level... then you should already know what motor you need to be running... or ask a mod guy at your track what they typically run. Usually 8.5 or 10.5

Not true at all. Lower turns = more torque more top speed.

With the new ESC's and timing advance in the software you don't need much more than a 10.5 and 17.5 in your motor arsenal especially with 2wd buggies. Boosting a 10.5 makes it insanely fast and too much for most 2wd buggies to handle imo.

WRONG!!!!


?Basics of choosing a motor and ESC/MSC and Brushed vs. Brushless Systems?

There are always a ton of threads about motors and ESCs and they are all usually variants on the same questions. In this article I will go through and explain the basics of choosing a motor and ESC/MSC, and talk about brushed vs. brushless systems.

When choosing a motor it is important to choose one that meets your abilities and budget. The first thing to consider when buying a motor is how fast you realistically want the car to go. I know you all want your cars going 50mph, but there are only a few of us who have enough driving experience to go that fast without hitting straight into a wall. The basics on turns and winds are as follows:

Lower Turn = Higher Top End/Less Torque
Higher Turn = Lower Top End/More Torque

Sorry Cpt.America, but RC-ZOMBIE is correct. There has to be a trade-off, you can't have a (relatively) both high torque and high speed. If you want more of one you give up some of the other.

So you guys are saying that if I hooked up my x12 3.5 turn motor to a torque measuring device and gave it full voltage, it would put out less torque than hooking up my vta 21.5 motor?

Why do you think crawlers use 55T? Massive torque.. and slow as a snail

last two lines quoted are WRONG!!!! just saying...

CPT.AMERICA "is correct".

As far as I know, a lower wind motor is more power everywhere. yup. the math proves it.

but:
Because you typically use a smaller pinion with a lower wind motor, it's totally true that this motor produces less torque to put down the same wheel torque as your weak motor with the bigger pinion.

I guess the rc magazines are wrong and your right FYI we are not talking about gearing!!!!
LOWER TURNS=LESS TORQUE
HIGHER TURNS=MORE TORQUE

Actually, I just now realized I don't even know what torque is... Eff me, lol.
