I cant believe your motor came loose.. just tighten and loctite a little more and should be fine...

Do you feel anything else is needed for the truck? are you happy with the way its performing

Dunno wether its a combo of the XL size conversion or what but it doesn't respond to mid air changes like I want it to but I need to drive it more before I can make any adjustment calls

Gotta say the only two things I miss about Bozeman would be the skiing, and the potential bash sites!

Red's fine, just use a lighter to heat it up. I'm not in Bozeman, im in Missoula, but close enough :P

Thanks Reno, appreciate all your guys support and excitement throughout this build. I know its nothing in comparison to alot of other guys custom builds but it was still a labor of love for me and im very happy with the results. I'll figure out what I want to tweak the more I drive the truck while i've still got good weather up here

Its a monster truck, not a truggy so its not supposed to handle like one. I may upgrade the steering servo per everone's suggestion about it here but that won't happen until next spring.

We're you kinda light on the throttle there? I noticed that there wasn't any ballooning on the tires.......

That and the tires are gorilla taped as well. I'll have more high speed runs in the next vid at a different location

Body turned out a much better fit than I was expecting. Thank goodness, as bodies for the XL are sorely lacking

[thzero]

Yeah but I went to Montana State, so thats why I said Bozeman! :)

You can definetly tell a difference; I've driven both my nitro XL (when it was one, and soon shall be one again), a buddy's Flux, and my RC8T conversion and its definetly different experience. MT is just as much fun for bashing, and sometimes more, as the truggy!

Looks good man! Looks like you are running 4s? 5s is the sweet spot, 6s is almost too much, but kinda fun once in a while. If you dont run too many cycles on those 2s batts you can just buy the same amount of 3s batts and still be ok as far as mixing 2s and 3s to make 5s. I bought 3-2s packs and 3-3s packs so i could run 4, 5 or 6s, or just all 5s. I only run 5s now because that is perfect for me. 4s is not quite enough spunk and 6s is like balls-to-the-wall, all-out, uncontrolable craziness lol. I cant even go full throttle, or anywhere near it, even in a 300foot straight with my flux on 6s. I can take it to where i cant even hardly see it and drive it towards me and still not be able to go WOT with it without it doing a backflip.

Allright guys, I need some input on overheating issues i'm having with FB2. I took the truck outside a little awhile ago in sunny, around 70 degree weather. I went to a local park and I gave the truck a real hard test run on a full set of batterys. I did alot of high speed runs, turns and wheelies in both gravel and some grass. I did alot of small jumps around 4-6 feet high with alot of throttle and braking as needed. There was alot of dirt and dust flying everywhere as I did donuts, skid turns and peel outs so the entire truck had dust everywhere on it

Within in the first few minutes, I stopped the truck and noticed the ESC fan was running. The motor didn't feel too warm so I kept on going as I stated above. I stopped the truck several times through the run and noticed the ESC fan running on almost every stop but I decided to just keep hammering away at it. Finally, I felt the LVC kick in at 3.5v at around the 20 min mark and I checked things out. The MMM fan of course was running and it did feel pretty warm around the casing but then I touched the motor and I nearly dropped the truck as the motor was searingly hot to the touch.

I touched the motor on the heat sink fins again. The motor was so hot that I couldn't hold my finger on the fins for even a second it hurt so much.

Needless to say, something aint right here and now i've got to dig through my setup and see what exactly is causing my motor to run so hot before I take it out again.

I'm theorizing it has to be one or combination of my mods including:

1. Sealing the front endbell holes with screws to prevent dust intake
2. XL chassis and axle extentions
3. Heavier and slightly larger tries

I double checked and I have a good mesh on the pinion and spur and im running the stock 20/44. I had the punch control set to 0%, drag brake at 10% brake amount 20% and reverse w/lockout at 25%. I have no unusual drag or binding on the tranny anywhere that I could feel and everything rolls smoothly.

That being said, what should I try changing on my setup to see if and how that effects my run temps?

Still no Temp Gun? Harbor Frieght they are like $8

This before anything. It may be 160F, too hot for comfort, but fine on the motor.

[josh9mille]

first i would try taking all those screws out of the motor and then do a duplicate run. I doubt its your tires since they are just barely bigger or heavier. The ext tvp's add what like maybe 3 ounces of weight? I dont think its that either.

[josh9mille]

Oh and remember this as well:

As reference I am running a 2200kv with MMM on 5S on a 16.4lb 5T conversion and I'm not seeing this. So it is probably not the XL chassis and its not the tires. Maybe it "sealing" the front end might be part of it but maybe not.

But yeah get a heat gun/temp guage.

Are the tires different size from stock that you need to adjust gearing? What about timing in the ESC? Low/Medium/High? I had some heat issues with my RC8Te and dropped down to the Low settings and that helped.

Really like the CORR body on the savage. I have a new SC10 body laying here I'll have to fit onto my Emaxx or Revo.
