ok. then you can build... ta da, the full sized old speedster. I ran it off of 3s 1300s and 2200s on a f pack motor! also with the light 2s 800 itll probably fly to. As long as you dont crash precisely on the tip of the wing, it is the best plane I ever flew, also being the plane I got the most flights on. Though after I crashed it on its wingtip, it was fix crash, too heavy to fly...
