This is a scaled down Cloud Dancer 40, suitable for a 10 to 15 engine. To build it, you’ll need to download the Cloud Dancer 40 plan and print it at 75% size.
The top stringer is 3/16 x 3/16. Make sure you don’t stick it to the inside of the fuselage side. It goes on top of the fuselage side.
Thanks to Tommy Dale for building the Cloud Dancer 10 in the photos.
