Buggy or 3906 (most power?) - RC-Monster Forums

hoober · 09:10 AM

I have a choice to put my most power in my Raze buggy (stock) or my e-maxx (3905 stock)

I'd like to use the second most powerful set-up I own in the other vehicle. I'm not sure which chassis is better suited for the highest sytem I have (it is 6S MMM) My second most powerful is a HV 4.5 on 4 or 5S.

Which chasiss would take advantage of the power better and hold up better? The thing is I've never ever drove an 1/8 scale buggy, and even though it is lighter I will be running them on the exact same track/conditions and think that perhaps the buggy should have the best sytem.

which would you choose?

The buggy has the heavier duty drive train.
The 6s pack on the track is going to be useless regardless which vehicle it gets used in.
4s is definitely the better choice for either vehicle,especially if the track is loose,dusty.

sorry, I edited it. It is a 3905 emaxx.

Can the 4.5 handle the weight of the E-maxx? You might consider putting the 4.5 in the buggy just because it's lighter and won't stress the system as much.

You can try the 4.5 in the E-maxx and see how the temps do for you. It's always easy to just switch them around if you're not happy with it.

Yes, I suppose. I've had the 4.5 in the e-maxx before, but now I have a single 6S pack that will be used with the MMM in either chassis. The hv 4.5 can use either config of battery, 4S or 5S. I just thought of something, maybe I will use the MMM in the e-maxx, use a MM in the buggy with a slightly smaller motor and 4S and leave the 4.5 in the e-sav where it's already running. None of mine are geared very high since my area is small.

The main question was where to use the MMM and since I am experienced with e-maxx and it's heavy I'll probably use it in that with the same 6S battery that works well on one side. I'll leave the 4.5 in the e-sav where it keeps tearing up axles (doh) and make a new system MM without BEC for the buggy with my next biggest motor since I have to get used to driving it.

I think the emaxx and the buggy are going to weigh pretty much the same, The maxx is all plastic where the buggy will have a lot of aluminum and heavier duty gears and steel dogbones/cvd's. Most of the weight difference will be in tires.
Personally I think the HV4.5 is going to be to much, It's a powerful set up yes but the KV might be to high for efficiant running without temp issues for racing ?
Hopefully someone whom can give a definate answer will chime in.

Yes, that's always the trouble with the 4.5 is it spins too fast. I use it with 14 cells on the e-sav and may even drop down to 12 cells or 4S lipo in the sav. 12 cells will soften it up, slow it down and make it lighter and better for my diffs/axles.

I put the MMM in the e-maxx (should be the most power I've ever had) It runs good and is nicely balanced. I'm pleased so far. http://www.rc-monster.com/forum/show...5&postcount=19

fixed my e-maxx problem too.
