Oh boy look what came in today!!!! I can not wait to start building this plane! If I am able to do the mid engine I will need to find someone to make a custom exhaust or figure out how to make a custom exhaust.

If you are mounting it behind the cockpit like Bell did you are also going to need to figure how to cool it as well. A functioning air scoop on the top won't cut it!

I purchased a fiberglass 1/2 cowling from Fiberglass Specialties (I have a lot of their stuff) and recently I found a guy selling the 1/2 cowl, exhaust, and wing fairings all in fiberglass. He also has the retro cockpit kit if your interested. .

Yeah these RCVs run hot from what I researched prior to getting it. I will try a figure something out.

I have a TF cockpit for it already. Thanks though.

I have been thinking about your cooling issue and thought I would share a piece of the plans to another of my projects waiting in the wings. The airplane in question is a Sopwith Baby, this particular design won the 1969 Scottish Nationals. one of the more interesting details is a cooling duct (see photos) running from the firewall to the bottom of the fuselage. Perhaps this will provide a little food for thought in your own situation?

Thanks, I can probably do something similar with the small cowl opening above the engine area behind the canopy. Not sure if that would be enough airflow but can try.
