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?

Gundam-Guy · 12.02.2006, 11:33 PM

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

zeropointbug · 12.02.2006, 11:58 PM

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.

Serum · 12.03.2006, 10:57 AM

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

Yeah, I'd like to see those batteries.

Serum · 12.03.2006, 11:31 AM

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

neweuser · 12.03.2006, 11:58 AM

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

Serum · 12.03.2006, 12:12 PM

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)
