Fuel tanks

Had a great flight tonight in Snoopy’s Revenge but i have a leak in the fuel tank that needs to be fixed and the fuel tank on ORV is beyond repair. Getting ready to build some new fuel tanks. The fuel tanks were made of .032 5005, new tanks will be either .040 or .050. I want to save the weight but i do believe life safety may need to come first.

Flew for .7 this evening, no bumps or wind what so ever. Beautiful country to explore.

ORV

Flew ORV today for first time in a very long time. I have made internal engine modifications to eliminate the loss of compression and increased valve clearance to take care of an additional problem. It was a great flight, no bumps, and great temperatures. Flew .8 hours with wot indicating at least 100 rpm more than ever on past and wot at end of flight was same as wot at start of flight.

ORV and the Verner 3V

Made another run today, temps in upper 90’s, ran for .3 at 2100 rpm, i had changed calve clearances from .20mm to .35mm, after run it would at full throttle it went back to take off rpm. It did run a little rough at times but believe i need to richen mixture at power.
