Thunder Tiger Pro 46 - Dead stick
The Thunder Tiger engines are ABN and not ABC. They used the
term ABC type engine - just like OS. George Aldrich indicated a few times on RCO that TT engines are ABN. As far as I know OS, Webra, TT, and YS have nickel lined sleeves. Generally ABN engines are ready to go after 1 or 2 tanks of fuel. The TT instructions call for a long RC plug preferrably an OS #8 or K&B - not a FOX.
