Hi Spy,
I thought you were running a JP. Goes to show that the STS is plenty fast. I just hope it's reliable and solid conrod wise as it seems to be sts's weak point.
I'll check it out next race. ( have to fix my front diff - after the few back flips i did

I just bought a used STS D28M off a guy, and it only has a quart of fuel through it. He had it in his HPI Savage and he used a roto start backplate. I am putting this engine in my truggy which I have set up for bump start. I see that STS sells a bump start engine but I can't find a bump start backplate to put on my engine. Does anyone know where to buy one or have a part number for the backplate?

i love STS!!
Hey there guys, I have been running a sts d12e for about a year now and it's been great. Only issue i have had with it is the o-rings behind the mid range needle leaked after a while. Nothing a $5 bag of o-rings didn't fix. So when i bought a buggy i had to get the sts d30m. It goes great but it just sounds like a motor bike. I am pretty sure the bearings are ok so i have no idea what it could be. Has anyone had similar problems? The temp, smoke, fuel ecconomy are all good it just sounds very loud.

Loud usually means either a loud pipe or an exhaust leak.

hi I run .21 engines
if this crank was in it, they just changed to putting these in
that's all, I think..
in general, black cranks are more hardened and more resistant
but opposite, they could eventualy break easier

thanx for your 2 cents. iam going to break it in later today or tomaro. is byrons 20 nitro 16 oil ok to break in motor with the stock 1aluminum and 1copper shims. my brother has the hyper 21 8 port race 2.7 hp at 38000 is this fuel good for him for breakin also he has same shim setup.and whats better sts d28 pro 5 port truggie or the hyper 21 8 port race black block. we have a little bet going.
