There have been a few models that actually do list flying weight but who's to know. The A/C that I am looking at states the weight is 11.5 lbs. I have a YS 1.20 DF that I am thinking of trying but of course the engine range states 1.10 and up. What is one to do? I could put a 1.80 Moki but that is already spoken for on another aircraft that I have which I am repairing. If I use the 1.80 Moki I'm not sure that 1.20 will fly the other aircraft as well as the 1.80 did. All I can do is slap it on and try I guess.

I do appreciate all the help and information.
