I have had a problem with the Verner 3V on ORV, but have made changes and fixed the loss of compression problem except my fuel tank has started leaking very badly resulting in need to build new take, it shoud completed and flight tested by next week end. SR 7-1/2 has had a leak in the fuel tank for some time but it was under control until recently when the JB Weld started leaking. I have drained the fuel and repaired the tank again with another JB weld project called tank repair, it does not seem to harden but is sealing the leak. I can again fly Legal Eagle XL SR 7-1/2 when ever I want to. Looking forward to be in Reklaw with SR 7-1/2.
