I just built this model using 1.3# 6 mm EPP foam. It turned out really flimsy and would have been better using 1.9# 9 mm foam but the 6mm is all I had on hand. It weighs 185 grams including 2s battery. I flew it today for the first time out in front of the house and gave the neighbor kids a thrill. It flies great.

I wish my kid would get into flying the one I built for him but alas it seems RC can't hold a candle to Xbox for a 12 year old. On a plus side that is some great flying from your son there Turbo.
