I have a complete trainer gas model for sale, Asking for $500 which is very cheap for what you get. Everything you need is included with a spare gas motor, just may need some TLC before flying. Please note this is not a toy and is only recommended for someone who is member of a flying club or serious flyer.
FYI you will need to have a lipo charger for the TX battery and the field box battery lipos included. Pickup from Carrum Downs Vic 3201
