not sure but i am pretty good at shaving weight and it shouldnt come in any heavier than a zenoah 26 equiped plane. in the underground world of guys that flyfastashell like me this has been done with dl and da 50s with great success. the secret is its not scale far from it. only use the extra power upline and while performing manuvers that require the speed . its like having the ultimate sleeper hot rod. ihave no need or desire to blow the wings off of it. i have a wagstaff to that with. this is going to be a fun plane with plenty of nuts. ill post more tonight as i finish up the details. i have upgraded all the important stuff to z bends 4-40 and digital hi torque servos. pinned all the surfaces and strengthend all the weak points.
