We're getting two today at the store. I already told the manager that nobody better put them out before I get there to, um, "check them out for shipping damage".

I think its NIMH. That’s how I’m charging it. I don’t see why you can’t use your servo just make sure the wires are the same as the stock ones.

This truck absolutely rocks just gear it up. Will let you know how it goes with 16, 17 and perhaps an 18-tooth clutch bell. Another thing I tried LST diffs for a fit and they slide right in. This could be an option for gearing up or to use as an upgrade because they’re much tougher. Mayhem ST gears are the same thing as LST only geared the same as the Hellfire. Not going to fool with that yet though.

I put the OS 30 with a 15 tooth on mine and it was way better that the stock 13 tooth. However it still had a slight nose down feel on jumps and a little more gearing will be necessary. I recommend shrink rapping the cvd pins and setscrews so they don’t fall out. It works like a charm. Make sure you check the motor mount plate bolts on the bottom and loctite all six of them or they will fall out.

Thanks for the info Zap the reason I asked about the receiver pack is the Futaba servo says to use with ni-cad packs only. You said you put shrink rap on the cvd pins and setscrews, I'm not sure what you mean but it sounds like I need to do it. I'm new to this side of the hobby, I've been flying planes about 5 years and have decided to try buggy's & trucks, Besides the Hellfire I bought a Rush evo, MGT 4.60 SE, and a CEN Matrix, I have my hands full trying to learn all the ends and outs so any help would be appreciated.

I took them while I was working on it but just for you badz here’s the bolts and spring wow eh!

On a better note, WES here is a shot of the shrink rap over the cvd pin. You can get it at any automotive shop.

On our track the Mayhem ST will beat the Hellfire with it's stock 13 tooth configuration down the back 130 foot stright stretch. We geared up to 16 tooth clutch bell and the Mayhem which goes over 40 mph can no longer beat it and it can't touch the hellfire in the corners. Gearing up also doesn't seem to take away the bottom end and I'm going to gear up to a 17 tooth bell and that should be really good.
Video is comming soon!!!!!!!!!!!

Well, I am new to this forum,new to this hobby,and new to this type of truck. I have ran the first tank of fuel through it. I let it idle with the tires off the ground. The next step was to take it out and run it at half throttle for a tank. Well it got dark on me,but I was noticing that it would not hardly move at all at half throttle and when I applied more throttle it would die. Like i said, I am new and would appreciate any help.

Also I went in to buy a revo for me and my son,but when I arrived at the shop, There it sat, all nice a pretty, calling my name. They just got them in.

I know the manual says not to most likely but start leaning it out a bit. If it's like the Savage the factory settings are extremely rich.

Well hi all i am new to the forum but i've been reading it for a while. I just got my hellfire and gave it a test run. I'll try to include some pics if i can figure out how. I mounted an O.S. 30 on it with a savage roto start (which works really nice) with an 18t cb. Dropped in some airtronics high torque servos and reciever and i was ready to run. The motor was already broke in so i got to play hard right away. I have run it only on pavement so i have no offroad results yet. Here are some of my opinions...


the first noticable thing is the steering and handling, its just awesome, it holds a staight line and corners like it was on rails. no chance of flipping this thing on corners. tight turns too.

the second thing that impressed me was the braking, wow this thing will simply lock 'em up at WOT.

I know 18t is kinda high, but w/ the O.S. 30 it still has plenty of torque out of the gate, no wheelies but i'm sure a smaller cb would produce some wild weelies.

after i had it warmed up a bit i mounted my etrex vista C to the rear shock tower and was ready to record some top speeds. (no way to measure acceleration yet). I ran it up and down the street a couple times at WOT and am glad those tires are glued cause they were major donuts at WOT. anyways, after a few runs i checked the top speed ... i got 46.7, so i leaned the motor out and made a couple more runs, next check i got 48.3 mph. I has an empty tank and didn't run any more (besides thats really hard on my gps), but i could have leaned the motor out some more, it still had a lot of rpms left.

I tried a few small jumps up some driveway embankments, and man does it fly and land smooth, this truck is gonna be something to contend with.

anyways, i'm no expert but i know alot of ppl are looking for some info on how it runs, here are some pics, maybe i can talk the wife into taking some video later.

Nice looks like mine but cleaner. Here is a [link=http://media.putfile.com/Motos-hellfire]video[/link] link for Moto's hellfire stock with a 16 tooth bell with some Mayhem STs.

http://media.putfile.com/Motos-hellfire or it's at the members videos

Only a small part of it uploaded so I'll try again but it shows a bit.

ok i have a problem here, Im looking into the truggy market, i got out of the 2WD stuff and need somthing a little more....i dont know, hardcore perhaps, I was really looking into the XTM mammoth st (from what iv seen its a great truck) but the problem is that none of the hobby shops around here carry XTM stuff or if they do its very minimal so I would have to order anything that broke (id rather not have to wait a week to fix a truck) The other thing is that i really want somthing with a 2 speed tranny, is there a conversion for the hellfire??

truggys like the hellfire and hotbodies lightning dont need a 2 speed tranny, even with stock motors they go over 40mph. Trust me single speed is the way to go with 1/8 buggies and truggies.
