ok i need to know how my rig will perform :p . its a mostly stock rs4mt converted to rwd. for the guts, i will be running a chili peper 540s 4400kv motor im going to run it on a 3s lipo and for a controller im going to use a mtronics pro.

may have traction problems because of a lot of weight in front of the rear wheels, but on pavement it should run good

Gustav · 12.20.2005, 11:44 AM

Traction would be my first thought too.That's why i generally don't run lipo in 2wd stadium trucks.I'd strongly recommend keeping it 4wd.If it's the car i'm thinking of you can run a 3s pack under the belt there.

the rs4mt is a truck. and i cant switch it back cause the small pulley im using is aluminum and it slightly wider than stock, so i cant fit 2 of them on the shaft. ive had a bl setup in the truck already, although it was slow caused my pos battery's, it still was fast enough to show that traction wasn't much of an issue. plus the way the truck is made and the weight is setup in it, its less likely to flip over when driven hard

Yeah i know it's a truck,i meant if it runs a pack transverse under the main belt then a 3s should fit under there,i thought maybe there wasn't clearance for your pack was the reason for the 2wd.

It's the same layout i've gone for with my xray T1 3s setup.

Anyhoo,it should be quick,what's a chilli pepper motor though?.If it was similar to a basic4200 you could see 50mph.

ya the batt sits just in front of the motor under where the belt used to be. the pack will fit but most of them wont. the chili pepper motor looks like a feigao s motor with a 5mm shaft and theres no end ball. here are some pics, the one of the truck is what the setup used to look like

and heres a pic of the motor

I wish they still made the electric MT.Seems like a huge hole in the market for an electric 1/10 4wd stadium truck which is odd because they would make perfect allrounders.

is it worth it to go lipo in a stadium truck? the lipo pack i wont to get is a 3s and weights only 198g, but to do lipo would cost so much more. the pack is $89 the low voltage thing is $26 and the balancer for the pack is $38 so thats like $175 with shipping. or if i wonted to save alot of money i could just through like 9 cells in there and get the same voltage and power basicly for about 90 bucks. the down fall is the weight. 9 cells is like 3 times the weight of that pack. how much of a differance in that going to make in speed and hadling?

Gustav · 12.20.2005, 10:36 PM

Well i run 8 cell gp2200 packs in my stadium truck.Fit's in the same space as 6 subCs(a fraction longer) and is a similar weight.weighs 412g but that's built as a solderless power tubes pack which adds a few grams.

There's no doubt the weight will make a difference,however depends on where the weight is where handling and traction is concerned.2wd trucks do need weight over the rear axle or they just go nowhere.

stampy · 12.20.2005, 10:43 PM

ok well this pack is half the weight of that. have you ran 8 sub c's in there before?

Gustav · 12.20.2005, 10:57 PM

They won't fit,it's a xxxtMF2,i'd much rather 10gp2200s,which i might try shortly,have to saddle the other 2 cells somewhere.

The 3s 3300 pack i just bought for my touring car fits in the losi though so i'll try that.It weighs 280g.I think it'll be slower though because traction is by far the limiting factor where i run,i go through a small fortune in rear tyres for it,they have to be fresh or it's just not worth bothering which is very expensive.

stampy · 12.25.2005, 07:29 PM

ok i fiddled with my truck for awhile and turned it back into a 4wd. so traction is not an issue. i got some $$ for xmass and before i spend it i goda know:). so how much of a diff. is it going to make going from 9 sub c's (like 600g) to a 200g 3s lipo pack? forget about traction and such just say every thing is perfected

Gustav · 12.25.2005, 07:33 PM

Excellent news.The weight loss should make a substantial difference.What are the specs of these Lipo cells?
