Worlds Fastest RC car record

[captain harlock]

Doahh, the bigger the motor is the greater the torque, effeciency and power the thing is going to give. You probably wont need the XL version because you're going to support it with high( very high) cell counts and it will simply not fit in your Corally RDX touring car, but you can ask MONSTER MIKE to bring you the Lehner 1920/5,6 or 7 turn motors. The first one is a HI-AMP version that eats up tons of amperage, but delivers you speed beyond 87mph at 14.4 volts when you gear it right. Its a hot motor and the controller that should handle it is the MGM 12012 or 16016 or the BK 12020 controllers. The other ones are quite torqueier than the first one and they can accept high cell counts
as well as be geared higher than the 5 turn 1920. Using the bigger ones ( 1930, XL,etc) will cause your car some real damage and fast wear of your belts, because you are going to give the belts more tension by using such an enormous motors and they will easily strech or slip from the diffrential's pully. I heared about someone from Traxxas who used the 1930/5 turn motor and the BK micro 15020 esc with 12 cells and he could not control his car( TC3) properly because of the extra power the 1930/5 provides and worse than that, the center drive shaft, as well as the four dogbones were all twisted and wrecked down. This is just an advice, but you are absolutely free to choose whatever fullfills your sensations.

The carpet Knife doesn't use belts it's a pinion and a spur

[captain harlock]

Ah, sorry for misunderstanding. Anyway the motors that were given to you are extremely fast and you will surely go beyond 100mph with them if you are using a pan car.

HeHehe >=) <- evil face

You have got some good batteries doahh? those are the key to succes!!

[captain harlock]

Yup, even my 1930/5 didn't work to its fullest potential when my batteries were badly built up. I fixed the problem, however.

i'm getting matched/zapped batteries

Captain Harlock, your dream E-maxx... ?

Last year was my dream e-maxx... but I had to sell everything..

I had 2 Schulze 40.160WK ESCs.. and 2 Lehner 1930/9 turns..

The most I put on it was 24 cells each motor...
the truck was around 20+lbs.. but man.. it was A crazy beast... I broke everything possible.. I had to make 10cm cvds for it... I never could go full throttle on it..

I don't know how fast it was goin'... but man.. I bet it was over 80 MPH.. :) with a total of 48 cells...

[aqwut]

I think the 20C LiPo's could probably drive the brushless cars pretty fast...

cuz GP3700's are good for 10Cs?.. I'm now sure about this.. some sites I see them rated for 60 amps.. and some for 100 amps... so I don't know which is true...

[lipomax]

GP's are good for about 100 amps with minimal voltage drop. According to some of Promods tests with his eagletree, I noticed that during peaks of 100 amps, the batts were sagging in voltage to about 1.0 volts each. Lipos with the same MAH rating can't give that kind of amperage with as low of voltage drop yet... 9 GP 3300's are more powerful than a 20C 3200 mah Lipo. 8s3500 is roughly equivalent to 18-20 good sub C's.

My next emaxx is going to be 10S 4400 mah lipos rated at 12C continuous and 16C burst. 37 volts and 70 amps.... That's uh.. over 2000 watts w/o even sweating!!!

I was WAITING ALL FREAKING summer for a high voltage Castle Creations controller, but it looks like I'm going to have to get a 40.160 or a 32.80. I think the 32.80 should be enough to take me to the 70 mark and the 40.160 if I decide to go 12S eventually. Later on this fall, I'll start posting some updates. I'm golfing right now.

[lipomax]

I meant taht 9 GP3300's are more powerful than a 3s 3200 20 C pack.

[captain harlock]

No money, no dream E-maxx, but I guess a mild modified truck with 9920 and 9L motor is a very good choice.

@lipomax, what is wrong with the smaller sized BK 3695?

[lipomax]

I didn't know there was a 3695 available. I used to have a 1895 controller and it was about the same price as my 18.97 and I found the Schulze to be better and smoother. I did like Castle Creations Mamba 25, but since they're SOOOOO SLOOOOW to release their product and because they don't have a HV one for cars coming out anytime soon, I'm gonna just have to go Schulze. I'll hold out just a little longer

[captain harlock]

It seems that you are going to get the 40.160 controller and pay a hefty $600+ for it. If you tak the 3695 you wont be paying lots of money plus you are able to support your truck with enough lipos. I just bought the Schulze 18.149 controller recently because I didnot find the 20150 available neither here nor any where in the net although I prefer the 20150 over the schulze I could not wait any longer and my B4 wants to rip some asphalt. I'm only waiting for the batts to arrive and after that I'll be flying.
