Wide Open Trottle. try here Cyrul break-in proceudre in another thread.

read the response & post by the great himself,Cyrul Josh.

ok i'm back, last i posted was on page 16 whatever the date was.
i been running my sts .28 since february, i have it on my savage with an SH max torque pipe and is still running great, i broke the string on the pull start but that's about it. i stripped a set of wheels hex all 4 due to so much power( i just got 23mm), i run the engine on the rich side so i can control the truck. i run the engine on my buggy inferno 7.5mp i modified the engine mount and made it fit and it run great as well. i'm going to order another sts 28 so i can just keep it on my buggy which i converted into a truggy so it will be fine.
the one thing i can say about this engine is that I never ever have to tune it, after i tuned if for the first couple of times till i like the power its been on the same settings ever since. i had it sitting for a month with gas on the gas tank, no after run oil or nothing and i just went and tried and it starts right up. i should also say that it starts on 2 or 3 pulls.
just though i let everyone knows!
thanks.

i also forgot to ad that i'm running vented CB, aluminum clutch shoes, 4 bevel gears and aluminum diff cases, other wise is just too much power for my little savage.

yea, u rock there.
yea, u need all those setup even for the mighty savage. any engine less, wont be as much fun as it now.
your buggy must be flying, man. keep us posted. and picture if u can.

is thgis engine powerful, durable and reliable?

anyone know if it will work in the revo and how much it will run me?

Newera makes .28 pullstart mounts and I use that? or is this engine just too much power?

I was looking for a .18TM but if I can't find one cheap I gotta get something else

u driving revo...??
well then its too powerful for it. stick with .18 only.
Imagine Savage, the big burly stronger bash proof truck... need to mod the drivetrain to sustain the power this STS 28 brought to it.
yea, too powerful for yer revo thats for sure.

Hey there, what mods to the drivetrain would I need t make to my Savage X for this engine. I've got 4 spider gear aluminium diffs. Do I need anything else?

Wheelie bar.

Ive run the motor in my savage-x with no problems. Im pretty sure the savage is meant to run a high power motor as this with pretty much no problems , except for wheelies all the time.

denifitely need the wheelie bar. thats why u need bigger Clutch Bell(CB) like 17 to 47 spur to tame the torque.
with my extended chassis.. it still wheelie on the right timing but not till it backflip as with stock chassis.
thats why John Scultz of Rock Concepts like Savage so much, he's like ambassador to HPI Savage, coz it drivetrain(mid) is bulletproof. he uses the K4.6 engine modified for racing.. n sometimes his picco with 1st gear lock. 2nd gear all the way.

i just post it what you need it, read a couple of post on top of yours. i'm running my sts 28 on a savage X too.
you can run your stock dogbones but eventually they will wear out the cups, faster than normall engines due to the power, the wheelie bar is a plus, i don't run one cause i don't like them, my savage doesn't wheelie it literally just pulls all 4 wheels and lands on its top, its funny as hell and crazy to see the power. that's why i run it a little rich.

here you go...

one more what the heck! yes my cooling head has a couple of broken fings.

this is not savage
it had flat chassis

that is my truggy, i don't have one of the savage in the air.

ohhhh, u wicked one
we were talking savage n boom u put yer truggy there..
nice flight...is that truggy with STS? hmm like mine. cool.
