Here are the specs of the plans I reduced and a few planning shots.

I first had the idea to build the Deception around a 28 year old ST G20/15 that I have which dates back to my CL days. I bought the engine in Milan while on a trip back to the old country when I was... 14 I think. Great hobby store called Movo. I remember the feeling of not knowing what to look at since my time was limited and I wanted to see and touch everything. In any case, the ST is still silky smooth but I had to find a RC carb for it so, with a little help from our favourite auction site, I picked up its sibling - a NIB G20/23 - in this case with a RC carb!

The two engines are almost identical except that the 23 has a slightly heavier crankshaft, a different head, sleeve and piston. Otherwise, the crankcases are essentially identical. Now, even though this is an engine that was designed in 1970, a 23 on this little rocket might be..., shall we say, dangerous!? With that said, given that the engine mount and crankcase are the same size, I am thinking of maybe just bolting in that 23... I also don't have mufflers for either one so, what can one do in such a situation other than pick up a header and 3.5cc muffled pipe from Mac's? [8D]
