I've done three or four Testors builds/conversions. Here's my latest:

Thanks Mark , love the sound first thing in the morning Smile

did you make the mounts for the Testors engine ? Tired w/ Coffee Read

Mark, that Testor pipe bomb .049 was turning some decent RPM's, 14,700 Thumbs Up

with that Cox 5x3 safety prop, once in the air, looks like prop would unload putting the engine within its peak power band, be able to fly on decent line distances. cheers

Also love the layout of your airplane, single wheel for less drag and ease of handling, no problem flying off grass circles. sunny

What plane is this?

This is the plane that is in the video: Blue balsa Plane

This is a thread on a plane I made that I called my Pipe Bomb Special, and the power pod I made for it using a pipe bomb engine: Pipe Bomb Special

I did another, but I can’t find the thread. Next time I do a pipe bomb engine plane, I’m going to make a bed for it like the first thread, but use Brownell’s Acraglas bedding compound for it to make sure it seats perfectly.

Mark, you came up with a good way to lock the engine into position, basically molding a socket out of epoxy to fit the curved underside with a plastic plate to hold it in place. Thumbs Up

Also brought up in those discussions things I would never know, like it is possible for the reed to pop out of its holder stopping all valving action. Surprised

Then I found it interesting in the discussion that the Cox reed valves were thinner than the Testor, bits of trivial to fix dysfunctional but restorable engines. Cool

Your plane's design is simple but functional and easy to build, which is great. Smoking
