RC Driving Style
Alight I'm relatively new to nitro rc just got my savage 21 the end of may but today i was outside and it wouldnt shift into 2nd gear even when i had it lean as i could without burning it up so then i richened back to normal ran it without second gear :depress: kinda boring but then i stopped it by me and it just died it wasn't to hot at all, and it wasn't very cold either it was at the perfect spot (225 F) so I'm lost what do i do it might have something to do with the transmission and if it is ill have to look in the book and do it but i dont think that would cause it to die and a perfectly good temp........... i need help if this has happened to you tell me what you did to fix it. Any help will be appreciated
 
although i do not have the savage, maybe i can help, but i need some questions answered.

1. When it stalled, could u restart it afterwards? If not, have u tried to restart it since the problem occured? what were the results?
2. On most 2 speed trannys, there is an adjustment screw that u can tighten or lossen to change the time/speed/rpm when the unit shifts. This is the number 1 cause to non-shift problems. Does the savage have this screw?
 
yes NA it has one


and Jus2krazy2007 before you adjust the 2 speed try to lean it out a bit and see if that works.if you have the stock .21 it takes a good tuning to get it to shift. if your are running little on the rich side it might not have enough rpms to shift. but don't go overboard on the leaning to where your runing to hot.
 
Heres what you wanna do:
Open up the Little rubber part in the gearbox. Look inside the right hole. Turn the Spur Gear until you can see the clutch inside the gear. You'll know when. Now you want to get a 2mm hex I believe and turn the BOTTOM HEX NOT THE TOP ONE! The top hex is used to secure the shifting mechanism to the shaft. If you loosen the bottom hex it will make your truck shift earlier. Try turning it a 1/2 turn. And then go by 1/8 turns after that. If that doesn't work, I dont think anything else will.
 
I will have to disagree with what shk said, not that it is the wrong way to adjust it.you said you just got it so you need to give it time to break in mine did not hit 2 nd until the engine was broke in . Adjusting it because you want to get into a hurry is not the way to do it. Because once you completely break your engine in you will have to readjust it again. If you do adjust it now put some loc tite on the screw it will work itself out. That why I think you need to push leaning before you try this. If it shifts at a lean setting your break in is not complete yet give it some more time. what your doing is raising the rpm and forcing it to shift. If it does not ,do what shk said. I got in a hurry with os wish i would of took my time. IMO your not broke in yet
 
Here's my 2 cents. Has it ever shifted? If it has, did you notice if the shift point drifted before it quit shifting. If you try to adjust the shift point screw, how easy is it to turn? Lean it out to about 240-250 f, 220s are too cold. Will it roll backwards? What does your CB to spur mesh feel like? And are you holding your happy thought when you run your truck?

This topic has been covered, but I'm not being a peepee. My savage had loctite on the shift lever from the factory and I had to disassemble the tranny to fix it. All of the stuff above is relavant and should be checked (except for the happy thought). If you get a chance, let us know about the above stuff and we will help as much as we can.

And welcome to RCNT.

It used to shift fine and i was runnin it a little lean and it still wouldnt shift and unlike normal i would hear clunking everytime i would push it i think it is coming from the gear box and it is plenty broken in i got it in may and have a little under 3 gallons through it any thoughts?

And also i could start it after it stalled it would run for like 2 seconds and stop i need some help. thanks
 
the set screw has probably backed out and it's stuck in 2nd (not really stuck, but shifting right away). When you say it makes a clunking, is that when it isn't running and you push it back/foreward? That sounds like the set screw is backing out and is hitting the gear. Refer to the book on how to adjust the shift adj screw. If the screw is real easy to turn, you'll need to take the tranny apart and put some loctite on the screw. I can help if this is the case.
 
what ever is causing the noise might be the reason for the stall. Is the clutch any good.I would tear in to it any way just to be sure.IF the screw on the trans. is not backing out.
 
Yeah, what he said.

Ok, that's :spam, but I had to get one in this week.

what do you think my first two post were:spam :spam
 
It makes the noise when it is not running and the engine is cold, actually thats the only time i ever do it :hehe: i took it apart last night and havent really had a chance to put it back together do you have to put the loctite on when the tranny box is apart or can you do it when its on? I'm planning on fixing it today thanks

And also i just got done playing with my car and it was running extremely lean but it had screamin rpms like when i would let off the gas to turn the rpms would still go on for like 4 seconds without it moving faster and without me giving it gas so then i stopped it by me to see what was wrong and it just died and i couldnt start it back up for nothing, whats wrong? :angry:
 
ok i got it shifting and everything now so its all good except for the "clunk" it doesn't really effect the ride much but when I'm slowing down you can see the truck bounce foward a little bit everytime it clunks its like I'm blipping the brake when I'm not what do you think is wrong with it :flaming: i really want to fix this cuz it is quite annoying any thoughts?
 
check your diffs roll the wheels in the front then the back & see if it is one or the other.sounds like something is binding some place.go through your drive line to narrow it down to one area.it could be many things.
 
Sorry dude, this thread dropped off my watch list. Have you opened the tranny? It kind of sounds like it has something to do with the shifter.

The other things I would check are all the bolts that have to do with the engine deck, tranny, etc. The fact that your truck is lurching when it clunks bothers me. It shouldn't do that. Something is hanging, binding, loose, or just not working right. How worn are the drive cups in the center (center ends on the tranny and diff ends of the DBs)? After a while of running, those will wear and it may put the DBs in a bind when you let off of the gas. By this I mean on the gas power is going from the tranny to the wheels, off the gas it goes from the wheels to the tranny. Take a look and see, let us know what's up and what condition they are in.

As for the dieing engine, warm engines can be a pain to restart. Check for bubbles in the fuel line, use a filter, and make sure the head bolts and plug are torqued properly. If ya know this already, all apologies, just trying to help.

OK i now know what is up with my heating problems I've been having lately the lsn moves in when i dont turn it how do i stop this do i threadlock it? or will it do no good? thanks

And yes i have taken the entire tranny apart i saw nothing wrong except for one of the gear setups was rubbing on the one above it in one spot on every rotation which i thougth might be causing the clunking noise is this normal?
 
Ok well i just went ahead and threadlocked it andits working great no problems so far
 
Man, I have to appologize about not getting back to you on this. If you used the blue loctite you should be good to go. The green stuff might not let you adjust the lsn very easily. Another possible solution would be to use a tiny ammount of teflon pipe wrap on the lsn threads. Anything that 1)prevents the needle from turning due to vibration, and 2)still allows you to turn the needle for future tuning should fix the problem.

Glad you got it fixed.

Also, the clunking is not really that normal, but the rear of the second gear gear rubbing the tranny case is, mine do it and they haven't (and don't) have any problems.


Sorry for the delay again,
Whitt...
