I flew this version of a Tiger as a gasser for two years

The overall weight is within 4 oz. of the gas version and the performance is fantastic. I'm running an APC 17X10 E prop and the airplane is very fast with more than enough power for any maneuver I can throw at it. Flight time is 7 minutes with plenty of reserve. Just thought I would share my experience.
