I love that huge RUDDER!!

You can save 3oz by replacing the main landing gear and 1 oz, if you put a micro servo for throttle and if you search more, you will remove 2 or 3 oz to get 8oz (1/2lbs) weight saving, where that plane begins to glide!!

SCOU, if you haven't mounted your wing tube in the fuse, it may be worth relocating rearward. Looks like there's enough wood there to do the job..

I haven't monted yet, but what advantage is to install that tube rearward?? It will be more tail heavy??
