fastest motor
 

i was wondering what is the fastest motor on 4s its for a 1/8 buggy i want to know what u guyz think

I'd guess this one http://www.rc-monster.com/proddetail...512_2dF&cat=20, 2600kv, more than a 7XL and being a 4pole motor, should have more torque

The Lehner 1940/6 would also be just as fast.

Define fast…. fast as in rpm or moving a car fast what car/truck have you got? There is not just a fastest motor. you can push a boat over 120mph with 60,000rpm but you can get a lmt 1010 which is 9231kv on 4s = about 136,000 rpm that’s fast but its no use to you because there is no power involved so define fast btw a 1010 on 4s will exceed mechanical limits lol 136,000rpm :)

He was asking about the fastest for a 4s powered 1/8 buggy. I chose that particular combo because it had a better kv than the fegaio 7XL and being a 4 pole motor it would have more torque and better efficiency. I don't have as much experience as others here, but as a rule of thumb, For monster trucks, 1/8 buggies and truggies, using 4s lipo's, I'd never go above 3000 kv on any and on MT's and truggies, I would keep to 2500kv or less.

just wondering do they make a 540c 6xl and would that help the heat problems?

does anyone know if the 540c motors have the same kv rating

Yes the 540C have the same Kv ratings as the smooth can versions.

You should say how fast you want to go, a 7XL would take you to 60-65mph in 1/8 buggy. However a LTM 1940 8t would take you to im guessing 70+mph.

70mph on 4S lipo.. Interesting...

If you have got proper lipo cells a 4S setup will get you at about 55 mph.

I would take a neu 1512 or a 1515.

It takes a certain wattage rating to get the speed. Not necessarly the motor.
For an emaxx it is about 2000 watts for 60 mph.

and 2000 watts from 4S is quite a lot.. :p

Yeah, I'd like to see those batteries.

Flightpowers come close.. Viruss managed to reach 53 mph on 4S lipo in his buggy.

A little off topic, but what is the max watts on 4s do you guys think?

according to maxxamps theirs can do 2480 watts in peak on 4S.. The flightpowers do the same. (which where the abolute first that gave their cells a 50C rating)
