It was the same thing with my idlers. I ran them on a 2200kv Neu and 4s for weeks without a problem, but I think it was just a matter of time. I changed them when I put my GroillaMax single speed tranny in. I'd say yes on the idler unless you stay brushed.

have the same truck but with a 1.5d on 4s

GOTTA get steel idlers
GOTTA lock into second
GOTTA get steel Center CVD
GOTTA get better diffs. I just spooled my rear. I snap it every 2 months....
GOTTA get 17mm


Get some LPR tires and i promise this thing will be another beast!

Their we go.:yes::lol:

Idlers i can get, no sense in lockin it in 2nd when i have the idlers, has MIP cvd's already, and im just going to wait until the diffs break to replace them

If your going with a brushless setup. Lock it in 2nd for sure. Otherwise you will have failure all over the driveline.:yes:

Actually, i found the 2nd gear would break the 3.3 center shafts. Puts more stress on it because of the 45 degree of free rotation it has. But your CVD's should be fine

What causes the diffs to fail, are the gears themselves weak or is it something else?

what about a rear spool?

The cup is plastic as is the case. This allows for flex and then the gears strip. The ring gear screws are too small. At a minimum get an aluminum diff cup, the modified ring gear with 3 mm screws and an aluminum diff case. This at least theorecticly corrects the flaws of the 3906 diff.

...or you could spool it.

ohh, thinking a diff for the front and rear spool.

Don't go with a spool. It will make it handle like crap. Keeping one in a straight line is impossible.

i found the gears brake sometimes, but its usually the inside of the diff cups. The plastic holding the spider gears just give...

and i use a spool in the rear and the truck drives perfectly

Hmm
Here's the list

-1 or 2 4908/3905 sealed diffs
-2 steel idlers
-possibly a spool

Sound good!

(welcome back squeeforever, have not seen you in a while)

Yeah, i havent seen him in a while..

Just picked up a MM and cc Bec for 60 bux (thanks chris) for the maxx.
20 bux left atm, gonna be idlers most likely. But on the bright side i can run my 4s zippy lipo with the brushed motors

Wasnt that the MM that was turning off every 5 seconds...

He Ironed out the problems apparently.. we will see..

We'll if anything does go wrong then you can always send it to castle with the replacement/repair fee which IIRC is $50 for a replacement/repair when not under warranty. Or just buy another MMM if all else fails. When I ran the MM on my e-maxx it preformed decent. I always had to run a fan over it because it got quite hot. I ran the MM on 5s a few times without issues but it got hot even with a fan running on voltage that its not meant for "8v". I really wanted to get ahold of a MMM but funds werent sufficient at the time.

Tried it on my CMS6900 motor and it worked just fine. Ian and I think you (Ben) told me that it was just going into overamp protection anyway. And when I plugged in the CMS6900 a few weeks ago before I soldered up the 6.5mm bullet connectors, on 2S the motor spun just fine throughout full throttle range for about 5 minutes. And even when it would shut off and on with the Medusa, it would never actually get hot and it would only do it when I couldn't keep it above like 1/2 throttle, and Ryan told me that motors pull more in those lower RPM's which would explain why the MM was going into overamp protection only when I couldn't keep it above a certain speed.

Sort-of correct. Whilst it is true that motors have a maximum efficiency range in terms of rpms, it is the esc that heats up when you use less than full throttle, as it has to 'switch' at a higher rate, and that in turn generates more heat in the FETS which leads to thermals.

Least it isnt an old msc that would catch fire if you used less than full throttle 100% of the time... (those were the days :mdr:)...

Ran it today with 4s lipo and the MMM, runs great and wheelies like a mo-fo.
the motors are on there way out the door.... probably going to get a feigao or something to throw in it :)

Your holeshots are shot.:wink:

yeah they are... trying to play chase the rustler up and down my street ;)

Put the 2200 motor in there. MMM with brushed= fail.

you would be suprized at how much power it has.

and the 2200= transmission fail:intello:

True, put a centre diff in there, get a flm chassis and get mike to make you a mount for a CF like he did for ssspconcepts

no need for a CD, i like wheelies :)
as for the chassis, maybe somewhere down the line

Nice ben! Flip "***" lol. So wheres my turkey bar?

strapped to the back of my emaxx :)

Nice, now be a man and stripped those gears with the MMM/2200 :lol:

F##k? Nice vid tho. Brings back memories.

Yah, im pretty happy with the truck, with what you saw i can floor it with the slipper locked and put it on the roof.. not bad for brushed motors..

I cant wait, If the rain holds off Mike and I are going to the track for a little practice :)

With the cen? or maxx? or both? :mdr:

was going to be the maxx, but mike didnt wake up till 12.... so not today- not to mention its raining

A man of few,well one word. Nice vid. The f-bomb had me rollin'. Why do so many people use that word when they roll there RCs? Sometimes mother comes before it though.

Hahah, i think he didn't wanna walk over to flip it over ahhaha,


Ben, yeah, my friend Chris was suppost to take me to the hobby shop then go powder drifting in the suby after, but hes sleeping.

Well, the brushed motors kicked the bucket.. ran then till they quit.. the brush hood temp got up to 225 or so.... They stink to high hell! I was running out in the yard then lost most of its power, would barely move on full throttle. I thought the truck was hitting lvc, but upon closer inspection the motors were steaming...:) Brushes are now nubs

If anyone have a L or XL feigao for sale PM me, not looking to spend that much cash.

Ouch, maybe you should just drop 20 bucks on a Kershaw 970? or 2 of em?

i Think we have a single 970 lying around... gotta press a pinion off though.
MM ships today

Just ran the truck with the MMM 2200 in it on 4s.. surprisingly, nothing broke! Thing will keep wheelieing as long as im pulling the trigger... then the fun ended then i lost the set screw for my pinion :(

Im really dumfounded that the idlers or diffs havent caused any problems yet, knock on wood.
