RE: Which trainer?
Beesa:
Not familiar with your "Indicator," but the Grasshopper is a nice little plane, larger than most 1/2A planes and almost damage proof with everything attached with rubber bands, including the engine.
But.
It's designed as a two channel plane, no throttle and no ailerons. Personal feeling is a full house plane (R/E/A/T) is a better trainer.
