E-Revo Motor Selection

[BL_RV0]

Which is best for a E-Revo 3.3 with the Tekno kit?
I'd like to run a mamba max esc on 3 or 4 cells. (lipo of course)
ive been thinking the plettenberg maxximum, lehner 2230, or something with the most power output possible, that is usable with a MM esc.

Since you're limited by the MM's 4s rating, that limits you somewhat. Shoot for ~30-32k rpm on the lower-end motors, and up to 40krpm for the higher end.

i want a motor thatll not cost more than 120 or so, and thatll give me as good torque as i can get. it also has to have a 5mm shaft.

[jokerjustin]

a 9xl? i run that and it runs great with little heat probs

[BrianG]

Well, there are really two options here at the site; a Feigao XL motor (~130 once you also get the heatsink/clamp), or a Neu motor, which upwards of $300 depending on size. Both have 5mm shafts.

[BL_RV0]

oh and i also need something that isnt more than 74mm long, as per the conversion by tekno

[BrianG]

Well, the Feigao XL motors are exactly 74mm long, but once you add the heatsink/clamp Mike has (almost required to keep the front bell from popping off), the total length goes to around 78mm. I would actually measure to see exactly how much room you have.

The Neu motors are shorter, but larger in diameter. Don't know if there are any diameter limits...

[BL_RV0]

well is there any other way to keep it from falling off without the extended length?

[BrianG]

Well, you could probably come up with something home-made. Again, you might want to measure exactly how much length you have, there could be an extra few mm's to spare to make it work...

[BL_RV0]

i dont have the rig yet, im going to find out what exactly to buy before i buy it.

I am partial to the Pletty!

[BL_RV0]

I'm seriously considering a pletty maxximum. What do you think about that motor paired with a mm esc with 14 cells??

I am using the Bigmaxximum with a MM and 5s. It works perfectly with 16/52 gearing and stock diffs. However, Mike has told me that for some reason all the new MM that are being sold cannot handle 5S or that they simply won't run on anything higher than 4S. Sooooo, with 14 nimh cells I would think you should be safe but i don't really have a clue because I have only ever run lipos. I don't own anything else.

ok heres my proposed setup:

pletty maxximum with fan
quark 65a esc
12-14 ib 4200 cells
truck will be around 7.5 lbs.

is tere any skid that alum or ti thats lighter than stock for a 3.3 chassis?

im also running the proline 37 series velos and the proline 37's holeshots
(apparently the lightest truggy rims and tires ever made, wheel 55g each, tires 122g each)

[dirt101]

your truck will weigh more than 7.5lbs trust me.
