Ok, totally new here, and kinda new to RC.
I have a Savage S25 RTR, with a few upgrades. And I hear these things are supposed to wheelie pretty good. Well mine won't! I am assuming it is the extra weight of the reverse setup, the aluminum brace bars, and the hd turnbuckles.
So I am wondering if I might get the front up if I added a tuned pipe, and maybe changed out the stock clutch to an aluminum 3 shoe.
And what about the shocks, mine seem a bit squishy, could that have anything to do with it?
Oh, and one more question, which way would I go on # of clutch bell teeth to get more off the line torque and less top speed?
Thanks all in advance~

yes, the 3 shoe clutch/flywheel is a great upgrade to the older savage, forgot i had done it to both of mine till you asked. i run 14t cb with 52t spurs (good low gearing for more torque)on both of mine .21bb&.25ss with the ribbed pipe that comes with the .25ss on both trucks and can put them on their backs no problem. I'm running the newer 4spider diffs with heavy grease and my slippers are all the way tight too.

my s.25 took close to 2 gallons to really open up? it will put it on its back now with 15+ gallons threw it? I've honestly stopped keeping track and just drive it. hardly ever have to touch the carb, the easiest nitro to use I've owned.

OK, I tried putting all of my spacers on the back rear shocks (2 ea) and this did not do it either.
So next the clutch and pipe.
So should I buy an HPI clutch, or should I go for an aftermarket, and if so, which one?
And next, does anyone know if those tuned dual exhaust pipes are worth it, or are they more for show?
Thanks again.

The dual exhaust is show only.. crappers for performance.
The tuned pipe is a great power increase.

A smaller cb for torque. You can only use certain combinations though.

I was a afraid of that.... dang!
Ok that being said, is there a chart for the gearing setups, which will work with what?

Very nice chart whipnet!

Tazz, keep in mind these are not 100% exact figures, these are only possibilities with that gearing. There are too many things to factor in for someone to tell you exactly what your truck will do with any particular set up but that chart is a great piece of info that should get you pointed in the right direction.
 
One question I think needs answered here since you stated you are totally new. What condition is your engine in and how well do you have it tuned? From my experience, the stock NS25 engine will do wheelies but you have to have it tuned really well. BTW, that's with stock 15/49 gears. The 52 spur makes it bit easier.
 
Engine is like new, and runs like it. Is also well tuned (paid someone to tune it and teach me to keep it tuned)
I think I may have the majority of the problem solved, all 8 shocks were extremely low on oil, so I took em apart tonight, cleaned em and refilled with Losi shock oil. This made a MAJOR difference in the height and stance of the truck. I didn't realize how bad it was really sagging, but now it sits at the top of the suspension. It also pops right back up when pushed down now.
Should my springs easily fill the gap without the preload spacers in place? I think the springs may be shot too.
I will find out in the morning how it does now.
 
The oil will make a difference on a few things but it won't cause or cure the sagging, that comes from the springs.

That may be the case most of the time, but try draining your shocks of fluid, and see how well the springs hold the truck up by themselves. Now I am not saying my springs aren't shot, I am sure they are.
Who makes good springs that will fit the stocks shock tubes, because I am not spending $125+ for a set of big bore aluminum ones.
 
I have a Savage X SS with the 4.6 - mine was doing wheelies quite nicely then I put the dual rear exhaust on it - no more wheelies....I destroyed that rear exhaust in two days...put the tuned pipe back on and instantly got wheelies again.
Just my 2cents

Ok, cool thanks for the input on the pipe, I am now looking at other tuned setups. Any suggestions?
Oh and um I am now able to do wheelies! The shocks were the main culprit. I can't quit get the front tire off the ground on pavement, but in the short grass I can pop it hard enough to flip it. Gonna go to the local park later today to see how it does in hard pack, they've been working over there so there are some killer tractor ruts.
Oh, and should I change to a better slipper clutch when I put in the aluminum 3 shoe?
Thanks all, you've been tons of help.

The HPI tuned pipe is an excellent pipe for the price. If you want to step it up a notch, go with the Buku.

And I recommend the Nova shoes if at all possible.

You can drain the oil completely out and it will sit the same as with oil in. The oil is for dampening, not support. If you noticed a difference you might have had trash in the shock or on the shaft that got clean out when you changed the oil but oil will not cause or cure sagging. Ride hight is controlled by springs, the shock compression and rebound is where the oil comes into play.
 
Man that Buku is awesome, but at this stage in the game, 109 for a pipe for my Savage may = my untimely demise. (as in the wife would kill me) So I will shoot for the HPI then.
As for the clutch shoes, do those just pop right on the factory flywheel?
Eddie
 
i still say go with the hpi ribbed pipe and the 3 shoe clutch/flywheel. wheelies really put alot of strain on the drivetrain.

what weight oil did you put in the shocks? stock is 10 and i forgot to mention in my earlier post that i run 35/40 weight. with purple springs off the .25ss on both mine.
 
I used Losi 50wt, I think it may be to much but it is what the guy at the rc raceway suggested. And for only $3.50 for enough to do all 8 shocks, I'm not complaining.
I am looking for affordable new shocks though, I discovered that at least one of my shocks is leaking from what appears to be an mold injection point about half way down one of the shock tubes.
And your saying to get the HPI clutch/flywheel set? Should I change the clutch-bell and spurgear at the same time, or does it really matter?
