Does anyone have a review of the new sts S12X3 engine? i ran a d3r a few years ago and it was pretty good.

I have a STS RS3.12 engine it is only about two years old and has only been used in about 15 races and then i went to electric and i decided to go back to nitro and was wondering if the engine is still any good? i had stored it properly and the engine looks almost as good as new.

Crank pins don't break from anything you could do wrong. They only break if from either bad design, bad materials or bad manufacturing.

Has anyone out there noticed on their new .12 size engine that the bore between the two engine bearings are not in line with the bearings themselves? If you're not paying attention it just feels like the pinch in the cylinder. Be careful fellas!
I had purchased a D3R that was misaligned. One of my buddies bought a D5R, who got the engine from another store, had the same thing. Take a look on the crank near the counter weight and you'll see rubbing marks in the steel from the aluminum case.

When I switched to an RDL Turbo II pipe which is a less restrictive pipe the engine delivered more power. The smoke output is now a stream on initial acceleration. The power output is impressive. I always used Byron's fuel.
What brand of fuel are you using?
