I too have toyed with the idea of a pipe enclosed in the fuselage, but it does not look like it will be in the cards.

Thanks for that somegeek!!!

Bob and Imd,

I am going to start out with a 12/6 for the maiden and first few flights, and then go down in pitch from there. I understand that this is designed as a slower aerobatic airplane think that it will perform a lot better using a low pitch prop in the long run.
The only reason I am using the OS 55ax is that I have the engine and it is real close in weight to a 46. I do have a 70 fl four stroke that I could use but we are talking more weight, although there is a flex header I could use to run the exhaust out of the cooling duct.
Now to get back to the build, I done very little with it over the past week and want to get back to it...
