Here's the finished model. RTF, 29 ozs[:'(]. It will be interesting to see how much punch this engine has. I'll start out with a 8x4 prop, just to see what the vertical performance is, might even try an 8x3, if the 8x4 seems challenged. It will be fun to see what this engine has got, I've owned it for quite a while, and this will be the first speedy plane it's had to pull around. I have a FATHER / SON photo here, I was too lazy to get all the aunts and uncles down from the rafters for an extended family photo. I still have a lot of the low diameter / high pitch props left over from the other .15 speed plane project, so it will be very revealing to see a performance comparison.
