Brushless CRT Questions

[Sower]

Ok, I've been in and out of just about every CRT thread there is, and I still have a couple questions about a setup. So if any of you have any input, I would really appreciate it. First, I'll give you the direction I would like to go.

I want to take a CRT Pro chassis, then put in either a Neu 1515 2.5 or a Lehner 1950. I would like to use the Mamba Max on 4 or 5 cell lipos. The gearing would remain stock, unless I need to go to the LSP front and rear diffs.

So my questions are:
1) Neu or Lehner? I know, this is an old topic but hadn't seen it dealt with specifically in regards to the CRT.
2) Will the MM run cool? I live in Boise, Idaho and the summer gets pretty hot. My goal is to have a setup that will have sick performance without having sick heat issues.
3) Lipo setup? Given my parameters in #2 above, what would you guys recommend?

The bottom line is that I want a bulletproof setup that can give me crazy performance, and have nice run times. I'm willing to go with a slightly smaller lipo and get a couple of them (swap them out) for the run times though if I need to.

So, any thoughts? Thanks guys!

Oh, I guess if any of you have a swette brushless CRT for sale it would negate this whole thread. :027:

With the MM go Lehner.
yes, the MM is a cool controller
4 or 5S, depending if you want it to go fast or redicilous fast. if you take maxamps, take the 4000 in 2P or wait for the new 5000 they have coming. Perhaps they have got what it takes to drive in 1P.

First off - thanks Serum. You always have great posts, and know what you're talking about. Much appreciated.

A couple other clarifying questions for you about your response though . . . on the Lehner, which turn would you go with? I thought I would go with the 1950/6 or 1950/7. I don't think I would go with the hi amp 6, or should I?

And about the lipos . . . I want to have a single pack, and I'm thinking about getting two of them and replacing them when one goes dead. That way I don't have to wait so long to re-charge. I'm also not convinced on the Maxamps packs from my research. Right now I run Polyquest and have had good luck with them. I've also had good luck with Thunder Power. Any other suggestions for me to consider? Thanks.

Imo go with a hi-amp, they come bare so you can choose whatever plug you want to use. I run a 1950/7T hi amp on 4s and it is perfect for racing. If you want a nice controlable setup take the 7T, if you need a bit more speed 6T is the answer.

The maxamps are nice for the money, if you get 8000mah 4s2p i doubt you will have any problems. If you want a higher quality pack the flightpower 4900's are nice, although i dont think they come in single pack formation in 4s.

Where did you get your Lehner? And how long did you have to wait?

[Sylvester]

I got it off Mike, when i got it he had the 1950/7 hi-amp already in the list, so i snagged it up:) It took 4 days to get here from mike. Dont worry, im sure mike will have those 1950s in stock soon enough!

You suck. Just kidding - I just know the Lehner's are notorious for taking forever if they're not in stock.

This is how we canadians get treated for trying to help! :):005:

Oh, crap - you're Canadian?!!! Just kidding. You know what I'm talking about with the long wait for the Lehners too - or else you wouldn't have jumped on it when Mike had one in stock. Right? :027:

No biggie - I' have time. I might order one next week or something to get it on it's way.

If you want a single pack, go for enerland 4350's or 5000 cells.

The 1950/7 would be the motor of my choice.

Reason why i was suggesting the Lehner over the Neu is because some users have got issues with this motor on the MM controller.

Nice, I'll check into that enerland pack - thanks. Nice tip on the Lehner vs Neu too. I though you were suggesting it because of the poles or something. I personally like the Lehner too. Mostly due to it's efficiency.

So, do you think I'll need a UBEC with the MM too? And would you suggest the 1950/7 hi amp too, or just the regular 1950/7? If my memory serves me correctly, the Lehners do better with hi-amp . . . ?:002:

[Sylvester]

The hi-amp motors have less ressistance compared to the regulars.
You will need a UBEC for sure, it will run alot cooler with it.

Cool, thanks.

Although the UBEC is totally new to me. Have no idea what to do with it or anything. I had just heard it's needed and wanted to make sure.

Well it was about 6-8 months back when i got mine since there wasnt such a high demand on them, i still jumped when i got it, though! :)

So do you guys think I should be considering any other motor/esc combos? I would ultimately like to go with the Monster Max, but who knows when that will be out. I've heard good and bad about the BK, MGM, and Quark. The Quark was in the running for me, but I think the MM is just as good and has better programming (not a PITA like the Quark). Should I consider another esc though? And if so, would I be better off with the Neu 1515?
