I fly 1/2A planes (.049) and as a rule we dont use any landing gear because the wheels are too small for grass fields for take off and they just catch the grass and flip over on landing much like most parkflyers do ..my electrics I can fly and land on the blacktop at the school so I leave them on.....pretty much any thing from .15 up will take off and land ok..although I often have someone hand launch my .25 and .40 trainers for fun....and I usually fly out of fuel and deadstick in[&:]...Rog
