Glen it is not my goal, but I could save a bit by switching my RX battery pack to smaller, cutting my muffler pipes flush with the bottom of cowling. Who know maybe I can get to 5 1/2 lbs. as it stand she is very lively. I put a low pitch prop on th4e nose to get very good vertical. She take off in 25', and has great rolls. I have plenty of power, most of the flying is at 1/2, power for vertical. I have never taken the wings off since she is built. She fits nicely in the trunk of my car.
