so why then do I ask do you need to shim the diff..... must be a design flaw !!!!!

RE: Official HPI Hellfire Thread
 

Dude... punk kids!! don't spell this well or call ourselves chickenfarmer... Wake up!!

RE: Official HPI Hellfire Thread
 

for your information know it all, after you have ran a few tanks the plastic will wear on any kit, including your hellfire. and to keep proper mesh and NOT strip gearsthis needs to be done, so way to show your level of intelligence.

RE: Official HPI Hellfire Thread
 

I had a Hellfire too. I sold it after only a couple of races. I was fortunate enough to own an ST-R, Hellfire, and LSP-R all at the same time.

My goal is/was to win races and the ST-R was the quickest means to that end for me. The Hellfire was not bad. I finished 3rd in my first race with it. But it seemed no matter the set-up, I couldn't get it to handle the exact way I wanted. I used alot "concentration" just to get it around the track constantly making corrections.

The ST-R allowed me to go fast almost immediately. I spend less time focusing on what the truggy is doing and more on where I want to put it.

I'm sure given some time, there will be a very good set-up for the Hellfire. It does have a bunch of options for set-up, its just trying to find the right one....

RE: Official HPI Hellfire Thread
 

Yeah, you are right it is a design flaw. You shouldn't have to reshim. First RC that I had to do that to.

But all things considered, its a pretty small one, easily fixed and can usually be caught before it becomes catastrophic. And as I've stated, in the few months I've owed it, thats been the only problem....

The CRT seems to eat diff innards from what I've seen at the track. Doesn't appear as though its something that can be caught without a tear-down.

RE: Official HPI Hellfire Thread
 

So way to show your intelligence...... (I quote your reply) Did you get a D in english.....

RE: Official HPI Hellfire Thread
 

Lets all agree all parts wear over time, plastic, or other metals, just because you want to buy a vehicle, drop it on the track and drive it dosen't mean its the best!! How many chassis are threr in formula 1 racing, drag racing, sprint cars, nascar, champ, irl, just because you bought a STr you think its the best, what a small world you must live in!!

RE: Official HPI Hellfire Thread
 

Info only. CRT dif appear to be non hardned and non helical cut..... these are required for high HP and torque

RE: Official HPI Hellfire Thread
 

I believe this is it ( http://www2.towerhobbies.com/cgi-bin...?&I=LXLGX0&P=7 )
I believe this is what you meant for front and rear. Now is the center diff different?
My DX3 came today. Nice little DSM computer.

RE: Official HPI Hellfire Thread
 

Ok fellas here you go!

i cant say enough about these upgrades. For those of you that know Bill and the reputation of BCE i dont have to say much,but for the ones who dont know-well lets just say that it dont get any better than what you see. I cant begin to explain the quality and performance of his parts. I have been running the pro kit for about 4 months and it is by far the best upgrade you can have for this truggy.

RE: Official HPI Hellfire Thread
 

wmff82 - Is it an "upgrade" because it does something better or improves on something? Or, is it because you spent money on something shiny?? I would think it should make an improvement before it is stated as "It doesn't get any better"?

So if your chassis and, Shock towers aren't bent/broken/tweaked how is it the best upgrade for this truggy???

I'd say the best uprades are radio and, steering servo since they are the things holding you back from unleashing the top performance. Not a new shiny shock tower! But, if your correct - prove it by putting the stock electronics, stock motor in your HF and, keep your new shiney tower and, chassis and, race me or someone else with stock towers and, chassis BUT, higher torque steering servo's and, the diffs tuned properly and, i bet the farm you will not say the best upgrade for the HF is a new tower or chassis!

RE: Official HPI Hellfire Thread
 

Again. I cant say enough about the upgrades. Well worth the extra money to get the truggy where it is suppose to be already.

With the more predictable attitude the truck has, you setups will become more precise and the adjustments actualy do what they are suppose to do.

As most of you serious racers know the stock chassis is junk, along with the towers which are made of the same material and they are bending left and right.

This chassis and towers may not be for everyone. It requires you to really pay close attention to the center line and suspension. As far as the drive system goes this is the best upgrade you can do to the truck.

RE: Official HPI Hellfire Thread
 

No Youve said too much already! That is no different that an "SS". I'd have to say these upgrades are meant for Hellfire owners of current technology. I got no issue with that.
"SS" is 7075 and light weight on BOTH deck plates and shock towers.
What is the weight of the bottom piece?

I'd like to see some bullitproof Diffs like we need.
Maybe a rollbar that keeps the body out of the Engine fins.
Some Ti driveshafts.
Better than Thread cutter screws holding in the plastic diffs.

RE: Official HPI Hellfire Thread
 

Im not gonna set here and battle it out with any of you. But I know for a fact that the material used by hpi is inferior compared to what is used by BCE. Just because it says 7075 does not in anyway mean its the same.

Diff's are a huge problem, your best bet is outting in the HB diff's.
Tony's screws IMO is the only way to go.

RE: Official HPI Hellfire Thread
 

i've come to see there is a few people on here that even when you are trying to help them all they want to do is argue, i guess people like that dont really need any help then do they.

RE: Official HPI Hellfire Thread
 

Hey, I didn;t mean to argue. I was just stating that to me "True Upgrades" are things that enhance on performance or durability. If you break something that i see no reason not to change it to something more sturdy the next time (RPM needs to get their Nylon/Plastic going for our A-arms ect). But to swap out the Chassis or Shock Towers which i've had 0 problems with just to say i did it is DUMB in my eyes.

My Hellfire is doing very well with minimal updates. I have a Spectrum radio and, a high torque Hitec Servo for steering. A set of 17mm 1/2in offset beadlocks with Traxxas Sportmaxx tires on it. I filled the center diff w/ 25k and, f/r with 10k fluids - I'm doing very well at the local outdoor track! The only ones beating me are not one specific truck but the one who drove better that day.

I love the hellfire and, it handles very well. I think it is on par if not more solid than the other truggies and, can be just as fast (or faster depending on driving skill) than the others. At first I was pissed that it came with such crap electronics for $600 but is sucked it up and, fixed that issue. [Now the stock junk is in a Retro Blackfoot.] Put Kanai or one of the other top drivers behind the wheel for a week and, you will see that it is 90% driver skill and, tuning and, every truggy/buggy could be the best.

RE: Official HPI Hellfire Thread
 

You're claiming "Inferior" and "Fact" before its been released, I find that a little tough to swallow!

RE: Official HPI Hellfire Thread
 

Lets keep this "civil" gents......

RE: Official HPI Hellfire Thread
 

Yes those are the correct ones, Once again just drop in and go, the center diff dose not require replacement, the weak area on the diffs is the ring and pinion gears , therefore the center diff has your spur gear that mesh's with the clutch bell, there straight cut on both gears and since we are not redirecting the torque will experience much less wear...

RE: Official HPI Hellfire Thread
 

I see a couple Lightning guys are switching to Kyosho Diffs...

RE: Official HPI Hellfire Thread
 

I was at the track last week and watched a guy strip a Kyosho Diff... It was a new truck as well!!, HB diffs work great for me, and I dont think anyone is putting more power to them than I am!

RE: Official HPI Hellfire Thread
 

Ive seen alot of kyosho's diff's blow

RE: Official HPI Hellfire Thread
 

Our track is about divided between Kyoshos and Jammins. With a sprinkling of Hellfires.

I've had to re-shim my diffs, but have yet to blow out one of mine. When I talk to the other ST-R owners at the track, The one guy that blew his out, admitted, he didn't even shim his diffs. My two buddies that shimmed theirs nice and snug are on their 3rd gallon of fuel and have not had to reshim.

My diff started "clicking". At that point, I re-shimmed. Didn't need new gears. So, I think some of those that totally blow out their diffs either shimmed them incorrectly to start or didn't heed the "clicking" noise. I've been running my re-shimmed diffs for a couple of race weekends now with ZERO problems.

BTW, A very interesting note. A guy at the track last night broke his Hellfire Chassis. I was completely surprised. I didn't see the chassis as a weak link on that design with such a heavy upper plate. So, it looks to me that the BCE Chassis upgrade is probably a good one!

RE: Official HPI Hellfire Thread
 

I cased a big jump with my stock one and folded it!LOL thats when i new it was a weak link


The shimming for those diffs in the kyosho is extremly critical.. This one racer has buggy diffs in and he is on about his 2nd gallon.
