Just a quick question.

[SpitFireV12RR]

I've got the Lx Comp...blah blah blah. Now to the point. I want to install a Throttle Return spring to the car but # 1, I don't know where I would hook it up to(On the carborator), and #2, I have nowhere to put it on the buggy. I wanted to know if this is a TRS as it doesn't look one(Its stock): And as you can see there, theres nowhere to install a TRS...should I just drill a hole in the mud guards and hook it in there?

 

[Monkey Wrench]

Yes, it is. I'd suggest using Marvel Mystery Oil as a lubricant/protectant for that spring. It beats paying $6.00 or $7.00 for a little bottle because you can buy a quart of it for like $3.00 at most any auto parts supplier!




























Sorry man, I couldn't resist. I tried, but I just couldn't resist.

Point realized...lol! Thanks.

On my savy mine wraps all the way around the carb to the other side (Hard to explain) and hooks on there.. Not sure with that layout though.. I do know that things to damn clean though.. ya get it broke in yet? Your in Florida, ya have NO EXCUSE for it being that clean man..lol..

and oh yeah.. can't go wrong with Marvin oil.. I use that to oil my exhaust bearings. Works like a charm.

Thanks for the tip, Andy. The guy at my LHS told me to use only Trinity bearing oil on my exhaust bearings. I even asked if traditional ARO would work OK and he said to avoid it since the additive in ARO that allows it to "cling" in the sleeve would actually break the bearing seals down. I'm guessing it won't? Good to know, man! Thanks for the tip.

 

[SpitFireV12RR]

actually...it looks like it goes the wrong way and counters agenst the servo actually, now that I'm looking at it(and messing with it). It looks like it doesn't pull the Servo back to idol from forward throttle, it looks like it pushes the throttle back from brake to idle. So I think I'm going to have to install one that pulls back to idle from forward motion.

Any good mounting places ya see? All I see is drilling a hole in the mud guards.

And 4u2nv mine's way dirtier than that. Thats a picure off the website.

Then you may, MAY, have the spring on the wrong side. There shouldn't be a spring being "pushed" by the servo to open the throttle.

Don't sweat it! I've done that countless times, putting the spring on the wrong side. Try putting it on the other side and see what happens.

Todd, in that set up it almost impossible to get a TRS to work. Most racers might rig one up, but for everyday bashing, just get a failsafe (FS). I use the FS on my buggy over the TRS as it saves on battery life and gives quicker throttle response.

BTW, MMO makes crappy muffler bearing lube , and should NOT be used for air filter oil as it is too thick.

 

[SpitFireV12RR]

...it came like that! I don't know if they did it for a reason or what...I'll just be safe and install a diffrent(aftermarket) one(instead of messing with something that I'm unsure about). DO you have any mounting suggestions, besides the mud guard?

EDIT: Well...until I actually get the money to get a fail-safe...a TRS will have to do. :shrug:

 

[Revo Rancher]

MW, s**t, don't mess with the guy, he might try it...!!! The spring is there to allow travel for the servo to move the arm the other direction to activate the brake(s). It might need some MMO, though, for break in and ARO...

OK, so when you give it gas, the servo rotates counterclockwise, right? It's hard to see the carb with the air filter in the way, so I'm guessing, now, that the servo turns counterclockwise, pulling the carb open. Am I viewing this correctly? Just want to make sure my bearings are straight.

I guess I'm wondering if, with your current set-up, the throttle isn't returning to idle when you let go of the trigger? Are you experiencing a problem here, or more looking for an insurance policy?

RR, I'm truly not trying to mess with him! I see now I had my orientation backwards! My bad, not intentionally trying to give bad advice. Thanks for catching it!

 

[redneckracer1979]

That spring is in the right spot. It is for when you hit the brakes so that the throttle servo linkage can still move when the servo horn moves.

MW...when you give it nitro, the servo rotates counter-clockwise. When you brake, the servo rotates clockwise. When you apply the brake, that little spring bunches up and when you let go of the brake pushes the throttle back to idle. When you give it throttle, that spring does nothing.

redneck just laid that spring out for you...if you are using stock servos don't bother w/ getting a TRS...it will degrade the performance of the servo, since you need to first use power (torque) to overcome the spring......the stock servos are not really strong to begin w/.....Like Revo said just get a failsafe if you are looking for some insurance....when you get a better radio setup (if you get into racing this will be more important than you think) get one w/ a built in failsafe....I've had way too many glitches from the inline stuff to want to use em again.....for beginners and bashers they can save your buggy from death.....

The picture he included looks like it is a stock photo from OFNA's web site, not an actual buggy photo.

I've got the Lx Comp...blah blah blah. Now to the point. I want to install a Throttle Return spring to the car but # 1, I don't know where I would hook it up to(On the carborator), and #2, I have nowhere to put it on the buggy. I wanted to know if this is a TRS as it doesn't look one(Its stock): And as you can see there, theres nowhere to install a TRS...should I just drill a hole in the mud guards and hook it in there?

#1)Plaidfish is right, a TRS will not help much if you have weak, stock servos.

#2) The spring you circled is not a throttle return spring. The purpose of that spring is best visualized by watching your servo as you go from throttle to brake. The spring is part of a mechanism that allows the linkage to close the carburetor when the trigger is moved to idle, and yet still allow the linkage to move further when you press the trigger to brake, to move the brake cams. If that mechanism was not in place, your servo linkage would bottom out when the carb slide did at idle. Which would mean that the servo couldn't move further and activate the brakes.

Its not a bad idea to make sure that the linkage is adjusted properly. That was one of my problems early on. I bought my car used, and the previous owner did not have the linkages set right. Check by removing the air filter, and use your transmitter to move the throttle servo. When you watch the carb. slide, it should bottom out with the trigger at idle, and should not move any further when you push the brakes. If it does, it is adjusted wrong.

Also, make sure you set your end point adjustments (EPA if your radio has them) such that the servo is not trying to press the slide much past the idle stop (when trigger is at idle or brake), or trying to pull the slide past wide open (when trigger is at full throttle). What I do is dial down the endpoints until the servo is not getting the throttle open/closed enough, and just barely add to the EPA until you see that it does.

KX that is what I was trying to say I just couldn't find the right words. Thanks.

 

[Monkey Wrench]

Spit, what Redneck and KX outlined is exactly what I was trying to get to by asking which way the servo rotated when you gave it gas. Like KX, I've had to adjust the spring tension on my linkages many times, and it is fairly simple. The only suggestion I would offer now is, before you start adjusting the linkage, center your servo first. That way you've got trim room to dial it in when you run it. Just an idea.
