    The reduction gear adds complexity and weight (8kg?), you can not handprop the engine. The Carden-Ford had 65kg, the G13 is 53kg bare engine. With 40 HP you do not need large propeller (propeller fitted to 'ESZ is 40" x 30"), so you save another weight and the wingtip speed goes down, no problems with prop noise at all.

    As you can see by the stabilizer, I could have done a better job prepping the skeleton for the skins- as evidenced by the little bit of micro at the leading edge. Compound curves are tough..

    From the micro, it would appear that you have some low spots or waves in the skin. What would you do differently, now that you have that experience behind you?

    Kind of hard to say, although I think I may try allowing the skins to float a little more over the ribs during gluing instead of stapling them every few inches. The puckers near the leading edge are caused by the staples pulling the skin towards the rib. They aren't very deep, just enough the see when the light hits it right. I think I could avoid that by using less staples on the ribs- so long as the ply follow the rib smoothly and any glue joint gaps are within T-88's filling capability.

    Hi
    Nice to see another Chilton underway, I have a long term project getting close to engine fitment using an early Mikron 3. looking forward to your updates.
    Cheers
