And the OS Alpha engines use that putrid oil recirculating system that causes tractability problems. Drill and tap for a fitting in the back of the engine and vent the crankcase oil to atmosphere.

Sorry to see another soul buying an OS. You could have done a LOT better than OS.

I have two Jett engines myself. If I could afford it, I’d sell everything else I own and have Jett engines only. Mine have barstock crankcases, but the sand cast case engines are superb as well. My .35 swings a 9x6 to 18k or better and the .56LX will run a 10x6 to 18k or better on 15/20 fuel and APC props. As long as they have a 16,500rpm ground peak, they’re going to run just fine. Launch at 15,000rpm and have fun. They unload like crazy.

The following video is from another member running a FIRE BSE .35LX engine in an LR1. You won’t get a 4-stroke to do anything remotely close to that.

Okay, you got me. Yes there are a very small select few 4-strokes capable of doing 200mph. Youíre right. But I donít know that I could realistically group those engines in with a .35-.55 2-stroke regardless of quality/manufacturer.

YS, like JETT is in a class by itself.
But, they ARE 4 strokes
My favorite 4 strokes at that!

I like 2-strokes better. Too easy to manipulate to get the results you want. Just boring the crankshaft can have a pronounced effect on how well the engine performs.

oh come on guys, don't get me going, I'm just have great hopes that my new HP 61RI GC is well noticeably more powerful than my dead-head 61FX.
