I have a couple of those "pipe bomb" engines, one with some sort of NVA attachment (upper right) on the back. The Testors McCoy would be a contender for the Firebaby if the fuel feed was on the other side. A mounted pipe bomb would not do for this application.

Are you going to stiffen the foam board fuselage?

Ok. Let's see the PeeWee .020 mounted up. I have one but have not yet run it. I have to but a propeller for it before I can run it. Do you feel it would haul the plane around?

No, Living on the edge.  

The wing and horizontal stab will have balsa fillets top and bottom.  Probably the only foam board fuse that I will make because you can't airfoil the stuff.   Rest will be 3/16" balsa.

Using an original wing as a guide I wet the wing and added camber and dihedral but it didn't last, just a bit on the tips.  Might use a steamer next time or go back and re-read you instructions.

I think a .020 would haul it faster than I could keep up.

If interested in a Wen Mac without the Rotomatic starter, here's an early model on E-Bay, next to nothing but is missing needle valve.

Nice looking plane there. Is that just varnished balsa, or does it have some sort of color added?

Maybe, but a great model builder.  That sure went together well.

I like the balance between the lead-out guides.

Congratulations....

That is Nice , how much wingtip weight do you have since the engine is mounted inboard ( something you don't see much of) ?

I'm impressed with the neat beam mount job. That's the most aggravating thing about any Wen-Mac/Testor-Mac.

Thanks Eric, it has a quarter under the right wing tip.

Thank you sir. You can also mount like my baby ringmaster, but be warned that if you nose it in hard the bottom mounting ear will break, taking the gasket sealing surface with it. This setup also runs and flies very well.
