Propnut,
I haven't seen the videos because for some reason my browser won't let me. I'll have to either try on another browser or try on my wife's computer. Also, I wanted to ask you about the thrust angles on your DVII. How much down thrust and/or side thrust did you use?, if you can remember.

Subarubrat,
You are right! The Ryobi is very tall from shaft to the top of the cylinder head, so I started thinking HMMMMM, SE5a? DH4? I am going to have to live to 150 to build the models I want to.
