Need Help picking new Brushless System
 

Hi, I am very interested in getting a new brushless setup for my e-maxx. I do not have enough money for something like a plettenberg motor or schultz speed control. I am currently running the Novak HV-Maxx, but have ran it into protection mode too many times by overheating it and I think the bearings inside the motor have gone bad.

Anyway, I want to run 8 cell matched packs and either a Feigao 10L or 9L and I wanted to know how much of a diference I will notice using a speed control like the BK Electronics 12020 Warrior which is rated at 120 amps versus the BK Warrior 9920 which is rated at 99 amps. Is this a good setup? I heard the Feigao motors have the best bang for the buck.

I could give your 12 reasons why not to buy a schulze setup.. :p

What do you mean? you mean you are going to run a 8cell setup or a 2X8 cell= 16 cells setup? 8 cells is net enough for a truck, you need more cells, when it are 16 cells you are talking about, i would take a 8-9XL and a 9920 as controller.

About them Feigao's being the best bang for the buck; Yups! that is the truth! They can be compared in what you call a highend setup, such as the plettenberg/schulze combo.

You can run the 7xl 8xl and 9xl on the 9920. I like the 9xl over the 7xl for the longer run time and same power factor. It is only a couple dollars more than the hvmaxx. I sold my hv for something better.

Hi Flossin', and welcome to the RCM forum! THE place for BL and Maxx related questions :D

I agree with the others (assuming you meant 2 x 8 cells)
Get an XL over the L. For 16 cells, if you want speeed, go 7XL. For runtime, go 9XL.

Those motors can be run on the 99amp ESC. Not a problem. But a fan on the ESC and/or motor never hurts.

Thanks guys. Ya I will be running a total of 16 cells. Sorry I didn't say so. Ha, an 8 cell setup would be pretty weak. I'm gonna try to get a nice set of matched 3300s that push some nice voltage.

I have a pair of B&T Matched Blister Packs rated at 1.200 Volts that pushed my HV-Maxx setup pretty well, but then I found out they were only rated at 20 amps so I'm lookin to get a nice pair of 8 cells somewhere near 1.200 Volts but at 30 amps instead of 20 for my new feigao setup. So you guys say the 9xl is the way to go for 16 cells then?

Thanks for the info guys!

YEah, i would take a 9XL! and get a set of the IB3800's they will serve you well.

Sounds good, anyone know a good place to get some nice Matched IB 3800's? I checked ebay, but most people are selling just 6.

pm mike, im pretty sure he can get them. i know he has matched 6 cell packs for 35 buck. i would vet 3 and have 2 extra cells incase one goes bad.

Yeah, mike is the man ! he can get them for you. And even solder them in the right configuration if you want.. (if he has got time though.. ) ;)

Try mike first , or try pro-match racing.com . I bought 2 7cell packs of ibc 3800's , the #'s are 1.18 & up for $ 128.00 shipped. This #'s are at 30 amps not 20 amp's like other battery matchers.

There is a guy on the forum. Goes by boom boom batteries. He is in with mike I think. I don't really know. check with mike and him.


I am not saying a 9xl is for you. It is not for everyone but it is a motor that I like personally. Even better than a 7xl. I have not ran a 8xl so I don't know much about them. The 9xl is a good motor for run time and power. I can run 25 min on gp3700 16 cells.

So in my gmaxx should i run my 7XL or a 9XL. i was going to put the 7XL in the emaxx and buy a new motor for the savage, but i will be racing the emaxx and abshing the savage, so maybe i should do the bigger motor i nthe emaxx when it comes to racing time????

It comes down to how long you are going to race toby. don't try to run a 30 min race with 10 min run time. It won't be good. the 7xl is a good motor. I just have come to like the 9xl better. I want to try a 8xl out so I can compare the three.

i will just be racing in an unlimited MT calss against everything, just normal races i guess.
