It isnt the ss kit i have but I have bin buying upgrades, so now my rtr hellfire is almost a ss .... But next season I buy a ss and use the rtr as spare parts.
About the carbon fiber. Its because i want to shave some weigth of the truck (and ofc. the look ).
What have you done to the diff leaks.... I have tryed to change the o-rings but it didnt helped.
And I think there is a lot of slop around the steering and the wheels. Is there any thing i can do to minimize that?
And my goal in the next season will be to end in the top3.
If you can give me any tips to beat the HN and xray truggys (is mainly thoes cars which is in use here in denmark) it will be great.

There was an individual who posted earlier in the thread that Kyosho P6 O-rings work to stop that problem. Apparently they fit just a little bit tighter than the stock HPI ones.

I haven't tried them yet, so I don't know how they work, but here's the link... http://www.amainhobbies.com/product_...oducts_id/4016

As for steering slop issues, the first thing I look for is slop in the servo gear train. A tiny bit of play in the gears on the servo are amplified many times by the time it gets to the wheels. Also, the bellcrank connecting arm that goes from the servo to the servo saver. I have changed this out to traxxas parts because they have tighter tolerances. Make sure there is no vertical slop in your servo saver, and that the bearings are good (shim if necessary). Also, you can coat the inside of the ball cups with CA glue to build up the material there. When you snap them back on, they'll be tight again. The only issue with this, is not to go too tight and cause binding in the steering. A couple other sorces of play are worn bushings in the ackerman arm or steering rack, whatever you like to call it... and worn axle carrier bearings.

Fixing one thing in the steering might not make much difference, but if a person goes through and makes each thing a little bit tighter, it will translate into a noticeable improvement at the wheels.

Kyosho P6 O-rings are the way to go ,.... I also use the 3.3 mm thundertiger o-rings that go in the grove half way down the out drives .... NO LEAKS at all ... this fixxed the problem hands down.

Guys, just finished the RC KAOS series race at our local track. First thing, they put on a great, well run event. If you have an opportunity to run one of their shows I would reccomend it. After round 1 of qualifying I had my SS around the 10th spot. For round 2, some idiot(me) thought the reciever battary would have enough juice for 1 more 5 minute race. Needless to say, it didn't. Although, the failsafe on my new Futuba 2.4gz system worked flawlessly. Dumb way to test it though...My time held up, and I qualified 10th, which put me 2nd in the "B" main. I ran first or second thru the entire 15 min and ended up with a bump up into the "A" main. With great pit work by my brother and some decent laps through the middle of the race, and attrition by other trucks my SS ended up 5th for the day. I couldn't be happier, I haven't raced as much as I should have this year, so that was a great result for me. At the end of the 30 min "A", the left end of the rear sway-bar pulled out of the plastic bushing causing some erratic handleling with about 4 min to go. With 10 seconds left the truck would sometimes stop, then go, then stop, put I managed to cross the line. The end of the swaybar got under the dogbone, and seriously bent it causing the drivetrain to bind up. So after a 30 min "A", a 15 min "B", a 5 min qualifier and about 4 tanks of practice, about 1 hour 20 minutes of track time for the day, I came home with a bent dogbone and a leaking rear diff. I would think the durability of the Hellfire SS isn't a question anymore.
Jagman, thanks for the o-ring tip, I think that will fix my leaking problem!!!
As far as the SS being to stiff???? I painted up my truck to resemble the Scott Taylor CORR off road Pro-2 truck. As Scott's paint supplier, I'm in and out of his shop regularly. He doesn't build his chassis to flex. It's the suspensions job to handle track conditions, that's what suspension is for. I undestand flexability is good for RC, but.....one of the reasons I like the Hellfire is because it's stiff, and lets the suspension do the work.

Cool man! Thanks for the update!

Yeah, it sounds like your truck fought a long hard battle, and survived it as well or better than any other out there.

\Hmmmm...... My hellfire is approx. 2 years old and I am on my third set of shoes, recently new, and only my 2nd set of discs.......

Man, I would say that it has to be something in the setup..... I run a monster of a motor (RB 928) and have not had that kind of damage.... I run alittle bit of rear brake drag, but other than that, I don't know what setup would have to do with it???
Could it be that some how the discs or brakes stick, and the sudden torque impact is stripping them out???

You got me on this one...........

Yeah, I'm still on my original set of steel discs and fiberglass brake pads as well, have been racing on them all summer. I'm not sure why yours would be going like that???

Hey Guys,
Does anyone know if this MIP flywheel fits the Hellfire? I'm using the axial .28 engine and a bump box.

http://www.amainhobbies.com/product_...ducts_id/14664

I'm tired of the pins backing out of the stock flywheel.
