Brushless TNX suggestions? - Page 2 - RC-Monster Forums

Thanks for the insight guys, it's been helpful. It depends on what I can afford at the time really as to what motor I get; I've been also thinking about a 6S LiPo 8/9XL setup, but that'd of course require a beefier ESC than the MM. So many options! Assuming the MM gets the software update, do you think a Neu 1509 would be up to the job?
I've never had a Neu, so I don't really know what the 1509 would be capable of. Obviously a 1512 or 1515 would be better, but I can't really bring myself to spend over $200 on a motor. Bear in mind that this truck would be a basher, so I'd like a top speed of 45 to 50...I know that's asking a bit much from 4S.

Well, I think I've decided on a setup; a 7 or 8XL Wanderer, with a 4S MaxAmps 6000mAh lipo battery and an MM. As for mounting the battery...well I've stripped most of the truck down and this chassis plate has got to be THE most difficult plate to mount a brushless system on! No matter what I thought of (mounting the batt on the rear, front, reversing the centre gearbox, having the motor in the front, etc) nothing would quite fit!:035: I do have an idea though...and that's to simply make a battery plate (perhaps 3mm ali) that extends off the side of the chassis. It should be strong enough, and will look ok once I've stripped the anodizing off the chassis. I'll relocate the brake servo to the front, and have the motor mounted on the other side of the chassis to maintain balance.

Anyway I'll shutup now, as I'm sure this isn't very interesting to ya...but I'll post updates when I get started in a few months. Gotta amass some funds.:027:

I wouldnt use the maxamps 6000mah lipos, ive heard alot of bad things about them, they will suck especially in a heavy truck like the TNX..

Id reccomend the 5000mah 4s maxamps pack or if you can afford the 8000mah packs id go for those.. Another option would be the TrueRc lipos.. ive heard nothing but good things about the truerc packs.

They that bad? Come to think of it, I did hear some things a while back about the 6000 packs not being that great...hmm. 5000 would definitely be an option.
What do you think about the TrueRC 6600mah 4S3P pack here: http://home.comcast.net/~truerc/custompack.htm (scroll down a way). The 15C constant discharge seems like it should be up to the job. The TNX weighs barely more than a Maxx, so the workload wouldn't be massive. Does anyone have any experience with this pack?

Not a bad pack, but imo id spend the little extra and get the 8800 4s pack or the 8000mah 4s pack for $130.:)

Dagger Thrasher · 05.14.2007, 05:50 PM

Cool! Would the 8000 pack be up to the current draw though? the 80A constant sounds fine, but would the 120A burst be up to the task under acceleration? Sorry for the all the noob questions...you might have guessed that I've not used a LiPo pack before lol!

Sylvester · 05.14.2007, 06:08 PM

It shouldnt be much of a problem. Ill let AAngel or squee chime in on the TrueRc packs, but im sure they will be fine. If you want to be even safer, id use the 5s 8000mah, but than you cant use the MM.

Ok, thanks for the help. It's just hat I don't want to buy a pack and run the risk of pushing it too hard! I think I'll stick with 4S though; there's not enough room as it is, and 4S would probably chuck out enough power. As long as the system pushes the truck past 40, I'll be happy. :)
