Hellfire Steering Problem
 

Hey I just got my Hellfire and am having blast with it. Earlier I jumped it and the axle and the thing that holds the wheel popped out. I put them back in and it was fine, however my steering was worse than it is. (Adjustment needed) It seems to not return when turned to one side. Here's a video;

Edit; OK I think I got it. I tightened the purple wheel under the thing that the servo arm is attatched to, so the two parts are flush. I still need help straightening out the steering. Yes the trim and the little turn travel knob is all the way up.

RE: Hellfire Steering Problem
 

Yeah, your servo saver was probably loose. I would personally get a better servo as a first upgrade.

Take the servo horn off the servo, then set the trim to zero on the radio (making sure the receiver on the hellfire is on of course). Re-install the servo arm so it's 90 degrees (see the picture below). Once you done that, start aligning the wheels making sure to give some toe-out on the front.

RE: Hellfire Steering Problem
 

OK thank you very much that fixed it. :D Now, when I turn all the way right, it's fine. But when I go all left, it buzzes, like something is straining. What's up?

RE: Hellfire Steering Problem
 

The servo buzzes? If that's the case, you might have fried the servo.

RE: Hellfire Steering Problem
 

Try holding the wheel in place and steering it; that noise. It's like somethings' blocking it.

RE: Hellfire Steering Problem
 

Well, my servo makes a different sound (high pitched squeal) since it's digital/coreless. Can you make a video of it?

RE: Hellfire Steering Problem
 

Here we go;

RE: Hellfire Steering Problem
 

Thanks for the video.

That shouldn't be a problem as it just buzzes because the servo is trying to turn beyond the steerings end-point.

RE: Hellfire Steering Problem
 

OK thanks a bunch. One more quick question; you know how the hellfire comes with two more servo horns? One has a "23" on it, the other a "24". What's the difference? Will one give me sharper steering?

RE: Hellfire Steering Problem
 

The numbers represent the spline number. The spline is the gear on the servo you would attach the arm to. They're just there if you want to fit it onto a different servo (different manufacturers use different spline sizes).

RE: Hellfire Steering Problem
 

The 23, 24, and 25 horns are for different brands. Each number corresponds to the number of splines on the servo's output shaft. Airtronics, JR, and KO Propo use 23, Hitec uses 24, and Futaba uses 25.

RE: Hellfire Steering Problem
 

OK thanks! But now this damn thing came loose again and completely killed the second half of my bashing-session;

This was the same problem as before!

RE: Hellfire Steering Problem
 

Hmm, that's a bummer. Mine has a extra nut under the adjustment one to hold it in place (see picture).. You can use thread lock on it to keep it in place. Also, the top of the servo saver assembly should go into that hex above. Make sure it's in before you re-tighten the servo saver.

RE: Hellfire Steering Problem
 

Know where I can get an extra nut? (Grow up)

RE: Hellfire Steering Problem
 

Here you go;

RE: Hellfire Steering Problem
 

Like wubby's link shows, a standard wheel nut will thread onto the cylinder. If you don't use the HPI piece, any metric nut will work, (like Kyosho, Mugen, Xray, etc.)

RE: Hellfire Steering Problem
 

I'm going the hobby shop tomorrow. Hopefully they'll have a few.

RE: Hellfire Steering Problem
 

Also is there any way I can sharpen the steering? It seems like I can only get wide turns. I really need a sharper turning radius if I'm every going to race.

RE: Hellfire Steering Problem
 

Start out by getting a digital servo (like the Hitec 5955TG). For now, add some toe-out to the front and see how it performs.

RE: Hellfire Steering Problem
 

A lot of how a buggy or truggy handles is dictated by the diff setup. What I raced with was 5k in front, 7k in the center, and 3k in the rear. Someone handed that to me and it turned out to be the best thing I'd tried.

RE: Hellfire Steering Problem
 

I went to the shop today and they said there was never a nut there in the first place. We even looked in the parts diagram and there wasn't any nut. He just tightened everything up really good so hopefully that will stay. I also ordered a roto start.

RE: Hellfire Steering Problem
 

Yeah, I guess that nut only comes on a Hellfire SS. You can go ahead and get the nut anyways, won't do any harm.

RE: Hellfire Steering Problem
 

I'll see if it comes loose again. If it does, I am buying that nut! (Wow that sounds wrong)

RE: Hellfire Steering Problem
 

Sweet! Now I think my frikin servo is fried! When I turn my car on, it sounds like it's spinning on the inside, but the gear isn't spinning even with the horn off! My engine also conked out while I was trying to burn the rest of the gas off. Plus, the little pin that holds the...thing that the nut screws on to that holds the wheel keeps falling out! http://www.sympato.ch/smileys/Grrr.gif http://www.sympato.ch/smileys/cry.gif http://www.sympato.ch/smileys/Grrr.gif

RE: Hellfire Steering Problem
 

Yeah, don't expect much from the stock servo.. What happen to your engine? Also, to stop that pin from falling out, tighten the screw inside the hub (thread lock it aswell);

RE: Hellfire Steering Problem
 

I think my throttle servo is going too. It seems like it doesn't brake as well as it did when I got it, which was Memorial Day Weekend, so it should still be excellent.

RE: Hellfire Steering Problem
 

Personally, I like using metal gear servos for the throttle.. As long as it has good speed, good torque, and metal gear, it'll be fine for throttle/brake.

RE: Hellfire Steering Problem
 

Yeah I think I'm going to pick up some new servos tomorrow.

RE: Hellfire Steering Problem
 

Cool.. Make sure the steering servo has at least around 200oz of torque.. If you can afford the Hitec 5955TG, then go for it!

RE: Hellfire Steering Problem
 

I got a servo that's name escapes me now for $35 and it has 140 oz. of torque. Once I get a better radio I'll get a top of the line one if it's not doin' too good. Right now it's in the shop being installed along with my Roto-start.

RE: Hellfire Steering Problem
 

Good call.. If I were you, I would install and work on your own RC next time. Gives you better familiarity and skill. That way you don't have to rely on your LHS for such things.

RE: Hellfire Steering Problem
 

I know but I'm terrible with wiring. I probably could of installed the Roto-Start but the servo...eh.

RE: Hellfire Steering Problem
 

Messing up servo wiring is full proof =P. You just plug it in the receiver.

RE: Hellfire Steering Problem
 

Alright I ran it today and it's simply amazing. The Roto-Start also makes it amazingly easy to start it. I jumped it off of a rock that must of been a good four to five feet off the ground and it took it in stride. Yay. I also had a catastrophic crash where i was going like 40 MPH of a jump and I hit something wrong, so it flipped upside-down and skidded on it's lid for about six feet. I was waiting for it to burst in flames but it didn't even have a scratch on the roof! Hellfire > tanks.

RE: Hellfire Steering Problem
 

Glad you're having fun! Hellfire seems pretty damn fun (only reason I say that is because I haven't ran mine, but I just ordered a pipe so I'll be running soon)!

RE: Hellfire Steering Problem
 

What do you suggest for the throttle servo? I am thinking of getting the RTR version as well, so I am definitely upgrading to a Hitec 599 first off for the steering. Does the throttle servo need to be replaced as well?

RE: Hellfire Steering Problem
 

I never feel safe with stock servos. I would definitely replace the throttle servo. I'm using a Spektrum Z590 for the throttle servo (100oz of torque, metal gear, and quick) I picked up off eBay for $20. If you're referring to the Hitec 5955TG as your steering, then that's a great choice!

RE: Hellfire Steering Problem
 

Ya, I was. Don't know the exact names yet, since I am pretty new. I am actually deciding between a SS kit and the RTR kit now. If I wanted to take the SS kit and make it as good or better than the RTR kit, with the above mentioned servo's, same KA4.6HO engine, etc could I do it for under $500? Perferably, around $450 or so.

RE: Hellfire Steering Problem
 

The 4.6HO is 200 bucks itself, so I wouldn't buy that engine. Definitely get the SS kit. Pretty much better than the RTR. I put a Axial 28 1S in mine (with a top-end pipe), but you can go for the new 28RR which seems like a great choice too.

RE: Hellfire Steering Problem
 

Is the 28RR a better engine than the 4.6HO? Should I wait for the new SS kit w/ 4.6 to come out? What makes the SS better than the RTR if the servos in the RTR were upgraded? Thanks.
