Back at building. In final phase.
To be truly high altitude cut turbosupercharger off underside of B-17 and installed in belly of RP-26. Found scoopy scoop for supercharger intake and intercooler for under right wing. Extended nose a pinch for supercharger plumbing room. Propeller storage bin yielded 3-blader with wider & longer blades than stock P-26. Good for grabbing high altitude air. Recon camera to be under left wing. Typhoon/Tempest vacuform Squadron canopy looks to work.
Then,,, what USAAC decal version to use ?
