What controller for 8S that has a true brake?? - RC-Monster Forums

jzemaxx · **What controller for 8S that has a true brake?? -** 03.21.2008, 02:56 PM

Hey guys, its time to upgrade my 9920 to something a little bigger that will take at least up to 8S and will run a 4 pole Neu as I'm ordering another 1521 1.5D to run on my 3905 emaxx. The catch is it has to have a brake since I don't have a mechanical system on this truck. Right now its running an 8XL on 6S, and just doesn't have enough to break 70mph. I have tried everything and just doesn't seem to have enough torque to get it past that barrier. So I'm hoping this setup will do it. What controller would you guys suggest running? The 1521 1.5D is 1900KV with 110 max amp draw rating.

I usually recomend MGM, 16024 or 12032, but with the problems I'm having... I'll not recomend you mgm, Mine doesn't brake with motors with more than 2 poles, with feigao works near perfect, but with neu or align 600xl... pufff....

Crap, I was hoping the MGM would have brakes with a Neu. Other then MGM their isn't anything reasonable out there with a brake. Someone needs to come up with a mech. brake system for the new emaxx...hehe

I have no brake problems with MGM 16024 and Neu 1515 2.5D. In fact, too much brake will do a front flip!

potreinas · 03.21.2008, 03:32 PM

I didn't want to say that it has no brakes, but mine has this issue that mgm is trying to solve.
I suppose finally i'll send it for repair, and this is the 2nd time. for the same esc. and this is 3.21 firmware.

Sounds like their aren't really to many options out there. Does BK make anything that will handle what I'm looking for or Kontronick? I just need brakes and 8S capability with the Neu motor.

BL_RV0 · 03.21.2008, 03:50 PM

I recall seeing a BK 12036 somewhere.... Can't remember where though. Plus, the BK's don't like multipole motors.

jzemaxx · 03.21.2008, 03:52 PM

Has anyone confirmed that the BK's will not run a Neu 4 pole motor?? I have a stash of BK 9920's and it would be nice to run it on 6S in the meantime till I can find a controller worth a crap to run this motor.

I would look for the new Schulze coming out soon. They will have the following:

fut-l-24.150WK (10-24 Ni-cells, 3-8 Li-cells, 150A (200A), Opto-coupler, Splash water protection and Water cooling)
fut-l-32.115 (10-32 Ni-cells, 3-10 Li-cells, 115A (150A) and Opto-coupler)
fut-l-32.115WK (same as above but with Splash water protection and Water cooling)
fut-l-40.100 (10-40 Ni-cells, 3-14 Li-cells, 100A (133A) and Opto-coupler)
fut-l-40.100WK (same as above but with Splash water protection and Water cooling)

Man I just wish my controllers were done.

Yes. They will not run 4 pole motors. In the manual it says they can run them, but when I tried it was a no go.

You could look at the Kontronik Jazz 55-10-32 speed controller. I have heard good results from people here on the forums with the Jazz.

lutach · 03.21.2008, 04:44 PM

I would've recommended the Jazz as I have a few, but the motor he will be using might be too much for it. Even the mighty Jazz might not handle the 1521/1.5D.

The 1521 1.5D doesn't look like it will be an amp hog. Since the emaxx is light compared to what this motor can actually pull I'm hoping amp draw will stay at a minimum. Also I will have it geared for 70mph or so max....or just enough to break that 70mph barrier. I'm only 3mph shy.....sad that I'm about to spend $600+ to gain those 3mph....hehe

The Jazz 55-10-32 has no problems braking a Neu 1512 or neu 1515 on 10s1p A123 (comparable to 8s lipos). If i want to i can lock all wheels. when i do have to much grip the car will make a front flip when i'm too hard on the brakes. That's why i reduced brake to 95% on my remote.

11lbs truggy with Neu 1512 (1400kv): clip1, clip2, clip3
Same Truggy with Neu 1515/2Y (1100kv): clip1, clip2

The Jazz ESC is able of peak Amps above 120A eventhough it's only speced for bursts up to 65A.
