hey guys, i love my mt4x4 but i feel like i don't have the right combo for it... with that said, i have the hobbywing EZRUN MAX 10SCT with the 3660sl 4000Kv. it runs 50 MPH on flat ground, and rips on the jumps off road, with a 3s (15 t pinion) but she runs really hot, enough to go into thermo only after a short time. basicly i want a combo that i can run fast on 3s (monster truck club rules) and not heat up quickly. thanks!
should i just put my current setup in my Tekno 410?

I suggest a 1/8 scale esc if you prefer hobbywing a max8 and a 1512 2600 or 2650 kv motor and gear up a bit 18tooth pinion.

I ran my ProMT 4x4 on 4s today and the rear bearing that holds the center drive shaft in the rear diff came loose. This happened once before and I put the bearing back in with no damage to the gears.
The rear shocks don't seem to be able to handle the extra weight of the 4s battery and system. I'll have to up the weight on the shock oil.

nice! You can try a 4s pack that is the same dimension as a 2s lipo from SMC and/or Protek.

Hey, RCWERKZ is in the house. Good to hear from you! Thanks for the tip. Is it 3000mah or something like that?

Hi

Does anyone know of any other springs that will fit on this truck?

Proline has a spring set for the front or the rear. https://www.prolineracing.com/perfor...ment-front.asp

Hi

I don't think those Powerstroke springs will work, the Pro 4x4 uses 16mm big bores.

Default Pl mt 4x4 steering

Got about 12 good bashes in with this truck and everything has been good except for the turning radios. I have adjusted the servo numerous times, made sure nothing was binding, tightend up the saver nut and still can't get full left and right steering. I have even tried 2 different servos. Going crazy never happened to me before with a truck. But wow can this truck take a beating!!! 6s all day with it

Oh wow, I never had Powerstrokes before so I thought that's what the ProMT had. Tekno SCT and MT410 have 16mm shocks.

If the pillowball screws are too tight it can bind up at full tilt. That may not be your issue but it's worth looking at.

Hi

What do you guys do to keep the servo wire from rubbing against the center diff cup?

I tried searching and didn't find anything so, sorry if this has been covered. I've had the MT 4x4 for a little while and haven't bashed hard with it, and today it started clicking under hard acceleration...very similar to a diff with the gears skipping/stripping. I took a quick look at the center and rear diffs, all looked good. Put it back together and it was fine for a while but started again. So I pulled the center diff again and cleaned off the diff fluid to get a look at all the gear teeth clearly. One of the side gears had shed a tooth and it was occasionally getted chewed on by the other gears since the tooth was floating around in there.

So, I looked up the part number in the Pro MT 4x4 manual for the replacement gears, and here's where my questions come in. According to the listing for p/n 6092-06, these gears are for the "Performance Transmission" they sell for Slash, Stampede, etc. So one question is, has anybody had problems with the diff gears? The other question is, am I the only one that finds it questionable that the gears used for the diffs in the Pro MT 4x4 are the same ones they use in the "Performance Transmission" intended for much lighter and lower powered trucks/buggies? Do I have the right part number?

Hi

How much lube was in the center diff when you opened it, mine was all but empty and I haven't even driven it yet. Or maybe you just had a bad gear. Yes those seem to be the same gears,

Mine had some fluid in it, but not much. I forgot to add above that I did clean out the original fluid and put in 500k fluid (not filled all the way though).
