We're using some of these for indoor combat 16 in. sq and weigh 5.5 oz. using a 4 to 6oo ma 2 cell batt. Not hard to differentiate as you paint on your prefered warbird.
These are made from $ Store foam so thay're more or less disposable. I'm runnind the 16 gram HXT motors, 10 amp ESC and 500 gram servos. Getting a little beat up
Just more food for thought.
