pulled my fuel tanks down today to remove the trash that was on the inside of them and I'll be damned if they didn't glue the bungs in with Hysol.

guess I'll be replacing them with the BVM Kevlar tank type setups.
measured the fluid capacity of the tanks, the center tank is 500ml, the two saddle tanks are 1100ml each for a tad over 91oz, should give a 10 min flight with the P-70.
