I recently built one for 2 channel rc, my best glide is with the C/G just on the second spar, despite it being burdened with radio it flys a treat, for free flight you will defently need a d/t, it'll thermal off a lit match!
I built mine from the plan rather than a kit so I was able to select light balsa for the tail, think mine is around 225 grams?
