RE: DP 300L
The laser cut 330 came out 2 years ago. I have one I got 2 years ago. It weighs 14 1/2# with moki 210 and CF landing gear and one servo per aileron. I cut the covering off the bottom of the ailerons and put a balsa stick X in each lightening hole to stiffen. Have about 150 flights on it. If I had it to do over I would put a DA50 on it. An OS160 would be NO good for 3D.
