:smile: :smile: you're sold on that STS .28 which is not a bad thing :)

Sorry ! But I wish I was kidding, I have been running Glow engines since 1973, I am sure I know how to tune a engine, cars/trucks/planes/boats/and helichopters. I have a lot of money in this savage! I doubt very much that the 3 speed would work, it needs more than 10% more speed to get past that losi lst. I thought for sure once I put that sts .28 in. and when I broke it all in I thought it was faster, But well it was faster than the stock .25! a lot of snott, But not enough for the losi lst. gearing is the main issue! the lst has a higher 2 speed ratio, and the diff's are higher geard. so I plan on buying a lst, and put my sts.28 on that.. then I can beat my son! thats the only way! on the lost ratio: is CB low 18 tooth, high 25 tooth, and the spur is 70t low and 63t high.. now that is some ratio's

1/8 buggies are designed to go around monster trucks :) Less weight and lower center of gravity woohoo

If your talking about a losi lst, well that is a 1/10 scale Monster Truck. but it is bigger than a stock savage

Nah, I was talking about a LOSI LST killing machine :)

A friend is going to power his buggy with a STS .28 :D I have a STS .21 in my buggy but being slack as I am break-in is not yet fully complete. (Currently working on building a brushless 1/18 stadium truck)

OK here is a good question for the sts .28 in a savage.. What would be the best (fast at high end) cb and spur) that won't strip out.. I had a titanium 49 tooth spur, wit ha 19 tooth CB and the CB wore out in 3 tanks after break in! so sau after 8 tanks. cb was shot! and it was a gpm cb..

Heres my vid of the STS in my ofna buggy on around Tank 7. I'd just leaned it out, and wasn't fully tuned, i also lost radio contact not long after (Receiver batt) lol.

Gee , watching that video made me go out and fire up my snowmobiles, seing that snow! AHHHHHhhhhh the smell of 2 stroks.. that buggy looks to go good. I have a Hyper 7 PCR pbs andwith the hyper 21 it was just a hair slower than my sons losi lst.. this is wht I plan on selling the slow savage and get a lst and put my .28 sts in my hyper 7.. it aught to be fast!

Yeah, it goes pretty good, i have it dialed in just right now, it just seems to get better and better, i'm gonna stick it in one of my savvys at some point and see how it goes in there :D

Hi dino.tw!!!

I just got and installed my STS28 yesterday.

I just have two concerns....

1. When I was configuring the radio, There are times when the carb gets stuck when im attempting to go WOT. What i usually do is 'double clutch' the throttle, which seems to 'unstuck' whatever is blocking the slide.

2. On the CG image of the shaft starter, i noticed that the hole for the rotostart is at the side. Will this fit the savage? I mean, the savage's rotostart hole is on the upper left corner. I hope you could accomodate us Savage owners :D


Right now im pumping some iron and strengthening my pullstart arm as im about to break in the beast! haha!
:D

ok i think i found the problem. I noticed when the engine is running there are bubbles in the fuel line which are not moving. So i gather there is lack of compression somewhere. So this should narrow the problem which is causing the engine to run high. Any suggestion's

That could also be a sign of BOTH the LS too lean and also the HIGH end.. Mine is all broken in, the LS is like 6 turns out, perfect responce! the HS is 3 turns out, and it is getting 37000 rpm. probably needs more time to get the 40000 rpm.. Rule of thumb! rich is Nice Lean is poor! best to run it rich than lean. it it sounds like lean is your problem.. What percent oil/nitro fuel you using? I was using 20% nitro and 12% oil. engine seemed to like it! ALSO! did you take the baffle out of your pipe? if so? put it back in for the back pressure and also pressure for fuel tank.

Re: just asking.....
 

Yup. direct fit/

I would suggest swapping your titanium spur with a good delrin one.

I can't help but comment here. LST powered by a mach .26 is a fairly rapid machine, there's no doubt. But on a track the high gearing doesn't usually equal a decent lap time - far from it with a big heavy machine like either the LST or Savage. I suppose it depends on what your priorities are.

For top speed, it's a merely a question of BHP, Power to weight and gearing. 55mph? I doubt it - how did you get this reading?
