I'm looking for some knowledge of the evolution of the Cubcrafters Sport Cub. What are the airframe changes from the original Sport Cub to the Sport Cub S2 and then again what is the difference when they went to the Carbon Cub SS. I am aware of the engine change to the CC340 on the CC SS but...

Sounds like it is a very common characteristic of the O290 series. Thanks for the responses. 5qts is my sweet spot too.

Oh, not seeing anything like that.

The cam slings oil right at the breather port no doubt, I was just surprised by the difference in oil loss at higher RPM.

I did replace the 1 qt from the first flight prior to the 2nd. I usually run about 5qts, anything more and it spits it out.

So I'm looking to compare experience with Lycoming O290D oil consumption or should I say oil loss through the breather tube. Have any of you found that you loose more oil at certain RPM settings? I just flew 3.6 hours at a higher than typical cruise setting of around 2350RPM and saw 1qt of oil...

I'm currently running a Props Inc Maple 72x46 and Im seeing about 2300RPM on take off and full throttle in cruise I can just get 2500RPM. The O290 D has a HP rating of 125 hp at 2600 rpm continuous, 130 hp at 2800 rpm for 5 minutes, but I can't get there to use it.

Well to come clean this is for a O290 on a Kitfox, since it is not a common installation I have found little assistance from other sources. I figured since it is a more common engine in the Piper arena I would ask here. Weight is certainly an issue however. I found that the Whirlwind seems to be...

Any suggestions for a good ground adjustable prop for a O290D? Looking for good STOL performance.
