Not at all. But it would put a big smile on your face! :)

gotta love it.
i think 10XL on 6s would do that aswell.

neweuser · 02.15.2007, 01:46 PM

Nah, the 1950/8 would be good on 6s. The one thing about the Neu though, the BK esc will not run it.
But the 10xl is a good choice too.

jollyjumper · 02.15.2007, 05:37 PM

wich packs would be good, need two 3S packs, they also have to be 24mm or less thick.

neweuser · 02.15.2007, 05:46 PM

Me personally would go 2 3s2p 8000mah...but that's me. You could go 3s1p...I would have to shop around to see what would be good....but two 3s2p would put you at 22.2v...so you would need to make sure the motor would work and the esc...i have not checked the specs on that though.

but wait a minute, will i be able to decently drive the truck on 6s and 10XL?
cuz i dont want it to be like my XXX-T MF2 with MM5700 and 2s lipo.
that one is crazy difficult to keep straith.
it just does big burnouts every time you gun it.
also, would 10XL on 22.2volt accelerate faster then 8XL on 14.8volt?
even if the top end is the same?
also, how does the li-saver works, does he automaticly adjust when changing from 4s to 6s?
does it even work on 6s?
thanks, mike.

As far as 14.8 on 10xl, you do not want this as the volts are too low for that KV rating. 14.8 on 8xl would not be bad at all. The acceleration would be good. 14.8 on a 10xl, the motor would be trying to draw too much. The volts don't have teh "punch" they need to push that low of a KV. Keep in mind the formula with volts and KV calculation for RPM's...14.8 would not be that great on a 9xl either unless you bumped your gearing up. A 10xl definately would be a lot for the 4s to push good.
The top end should be pretty decent and should stay controllable. You can go 5s and the motor (10xl) will be more than happy. This is what I run on mine and I have good temps and a great dependable system.
The li Saver will automaticlly cut off for you when using the lipo, just wire accordingly (like ubec kinda) and you are golden.

that makes sence.
but is that actually because of the motor's resistance?

Honestly, that one I cannot answer. I think it has to do with the rating of the motor, what it's capabilities are as far as amps, volts, etc. which may be due to the resistence factor in some ways. But the motors are built for certain KV's. There's a lot to this and gets real technical which I cannot get into. But, let's say for example you try the 10xl on 4s. It will run poorly and most likely get hot. Remember, you want the motor to be running around 30-35,000 RPMS technically, which 14.8 won't reach. Now, an 8xl on 4s would give you decent run times and what not. It's rated to handle or "do" the lower voltage, this is due the the number of winds...8 vs 10 and the kv rating...if this makes sense. I know it's a bad explination, but this is the best I can do without knowing all the technical stuff.

jollyjumper · 02.16.2007, 12:00 PM

thanks for trying.
many thanks for that.
but i kinda start to understand now, you cant make a truck go slower then certain speeds with BL it seems.
so if i would want good performance ( temps, runtime, response time, ... ),
i have to get to a certain speed on a certain motor.
so on 6s it would work well with 10XL and on 4s it would work good with 7 or 8XL.
wich would now accelerate faster given the correct gearing and top end?

neweuser · 02.16.2007, 12:06 PM

Well, you can get a conservative system. Yes. With the right KV and volts with the gearing you use. A 10xl on 5s seems to be what you are looking for. You can get the 9xl on 4s if you gear it up, but your run time won't be that great as the amp draw will be more. Or even the 4s and 8xl would be good too, you will get low to mid 30's and your truck will be controllable.
The thing you don't want is like 5 or 6s on a 7xl, this will be a very hot system, and will be fast. Still controllable, but not dependable. Really, in an MT, it's hard to get the higher speeds, you need voltage for this. If I were you, get the 8xl on 4s, or 5s and 10xl...maybe even 9xl for more torque and top end....

jollyjumper · 02.16.2007, 12:15 PM

huuuummmmmmm, i will dump the tranny now.
the truck will be geared like a truggy.
4.3 diff and 46 C/D spur.
so that brings gearing from 16.48 to 10.32.
i'm pretty shure i should start out on 4s, else it will to much for me to handle.
i will try and get hold of those trakpower packs.
wich wind should i take with wich pinion?
and again, many thanks for your effords to help me select an proper system.

neweuser · 02.16.2007, 12:31 PM

OK. With 4s and an 8xl, if you are running a center diff? On the slipperential I gear it 16T pinion with the Revo spur. I run the UE 1/8th diffs. the center diff in the slipper is the Hot bodies I believe. Not too fast, but fast enough for a track...this is in a gmaxx.
If you were using the tranny, you could gear it 18/51 mod 1....mod 1 is all I ever used, so not sure...
