Fleet Finch
I flew my new sport-scale Fleet Finch for the first time today.
Scratch-built from a plan I got from Traplet.
Spans 67", weighs 7.7 Lb less fuel, powered by a Magnum .91 RFS.
Dummy engine was made by copying the real engine's cylinder, since adding plastic dummy cyls just didn't give the right effect I was looking for.
It's a dream to fly...

Looks great! How did you copy the cylinder?

I carefully "reverse engineered" the exterior of the real engine and then produced cardboard templates of the various cooling fins.
Next I made the dummies from balsa, ply, and dowel.
Fuel proofed and painted, and used some aluminum tape on the "rods".

RE: Fleet Finch
WOW!!! That's a lot of work on those dummy cylinders. I assumed you figured out a way to vacuum form or mold them, but making each out of balsa and ply? Great job.
