I built the PICA 1/5th WACO about three years ago. Finish is 21st Century Fabric and power is an OS FX .91. The battery had to be mounted under the engine to get it to balance.

I was very concerned that the plane would be under powered. It flies great with this engine and a Zinger 15X6 prop. It will look from level flight at half throttle. A pattern flier in the club put it through its paces and did some amazing rolling circles at partial throttle.

I will certainly build another one day. Hope the one I have now last quite a bit longer.
