Good Afternoon Everyone:
A couple years ago, I purchased the aforementioned (vintage 1995) WACO (assembled) at a garage sale with the intentions to restore it. The Mylar covering has a few punctures in it. I have to replace all the flight line electronics to work with my Spektrum DX6e. My issue is conversion to electric flight. I tinkered with nitro but found it messy and difficult to use. All my other planes are electric. How do I determine what size motor and esc for this bird?
Thanks in advance!
