RE: Rascal 40 first flight...
I often wish I hadn't sold mine. It's a great windy weather plane, fun to fly backwards, etc. I can't imagine a 1.00 4 stroke in one, unless the front end was modified. When I first got mine, I was planning on a .65 Saito. The crankcase was too wide for the wooden mounting rails, so I went with a .56, which was perfect, both in fit and power. I used a 12-6 MA prop. My only wish was like my wish for many ARF's, that it was available as a kit. I re-covered mine with Solartex after skinning up the original plastic.
One day I might pick up one of the 110 size versions. I got to fly one and thought it was even easier than the 40 size. This has to be one of the better all-around ARF's out there.
