links please?

the 8XL can be bought from rc-monster its a wanderer (from BK/Lehner) and the 9920 is a BK too.. (Mike sells them too)

they are the best bang for the buck.. and if you are planning on using 12-18 cells you need the 7XL

here is the link to the producer of those items.

9920 controller

feigao 7XL

I can't find the 8XL on the site but i found the esc

if you are on their site, you can see two motors, choose the left and in the popup, choose the 20. its the XL serie, 8 windings.

How many cells do you want to use?

i figured out how to put UP TO 20 on the car so what is the max the motor could handel?

why use the XL series rather than the S series?

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

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!!

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...

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...

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.

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

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?

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

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.

Why do you prefer the BK micro series over the Schulze future series?

can the 3695 use 12 lipo cells?....

That's why I want the 40.160, I'm gonna sell my 18.129 and my 18.61 to buy that 40.160.... when I had them last year.. they were big.. but never got any warmer than room temperature.... I even drove my M/T into the pond, fully submerged and the ESC and the Motor was fine. :)

Well, 36 cells of 1.24 volt each is 44.64 volts. It should work..

it would save me lots of money if I could use 6 lipo's on the 3695... :)

but doesn't each lipo cell max out at 4.2 volts...

so 6S would be about 25.2 volts at 4.2 volts a cell..

Has anyone tried 6s on a 3695 or 36120 yet?.. thanks...

I tried 6s and 8s on the 24.89 controller which is *only* $259 dollars. And it worked flawlessly.

First of all, programming the BK does not take that much of time.
Secondly, the Schulze esc are programmed manually in most cases through 6 switches which are very small and subject to damage more than the red jumper that exists in the BKs.
Thirdly, Schulze do not have a good distributer in the USA and so does not BK, but atleast there is a place called rc-monster.com that provides top BK services and sell them for humble prices.
Fourthly, all BK esc are equipped with large, finned, transversed heatsink and most of the Schulze controllers do not use finned heatsinks.
Fifthly, many people fried their Schulze controllers whom I read about in many different forums besides the ones over here and I've only read once about someone who fried his BK 9918.

Perhaps there have been a lot of problems for others. As for me, I've never had problems with Schulze, BK, Hacker, Castle, or Novak brushless controllers. Maybe I've been lucky, but after owning a 12.97, 18.97, U-Force 75, 24.89, and 32.40 and never had problems, I guess I'm lucky.

Oh, I also had the MGM too.

Well, suit yourself.

Lipomaxx; You are lucky for sure!

Monster Mike who is in the brushless scene for quite some time has smoked quite a few.. i myself smoked a few too, (only 3 though, nothing compared to Mike..)

I've smoked around a SH*T load of 18.61K's and one 18.129(my fault reverse battery)...

but the 40.160 is a very nice ESC... just too pricey...

I've taken out 2 Warrior 9918's (sent first one to BK, got it back 4 months later, damaged it again, now Mike has it). I also have damaged a MGM Compro 120amp. I am not very lucky with RC electronics!

the price on that 40.160 is not my biggest concern.. you need a 1:1 scale truck to bolt it on..

hahha...

one of those bolts on pretty easy on the E-maxx....

Yeah, you only need a 1/5th scale body to fit over it.. ;)

you know what i mean, its size is absurd... redicilous.. nice for a boat, or a 1/5th but to build a car that is also a bit in vissible condition..

Yeah, I know...
but It's nice to know that you have an invincible ESC...

What?? Invincible...? you noticed the name schulze on it??

;)

No, to be honoust never heard about anyone ruining his 40.160 though.. (neither about someone ruining his BK36150)

36150 is an awesome size... but schulze is the only one that can take 12 lipos.. that's my problem...

I bought 4 pacs of 6s lipos.... I should've bought 5s instead maybe..

how much power is that 2250 motor though... I wonder if Mike can get this motor....

Mike can get it, no problem..

The 2250 is quite a bit stronger..

You can rebuild the packs... it should be no problem...

Rebuilding Lipo packs will be hard to do if the tabs are welded together. If they are soldered, then it isn't so tough (just unsolder). If you converted all of the packs to 5s, then you could make an extra 4s pack!
