Well with Pink foam you did a pretty damn good job, could have fooled me, thought it was store bought!
All I could find that would fit under the canopy of the GL FW-190 (a figure only 1-1/2 to 1-3/4 inch high) are the last ones on this site:

The "SIR312 Fighter 1:12 Scale Pilot Head ..... $ 4.60" could pass for a WWII german pilot if I repaint him with a green uniform. SIR412 Cougar 1:12 Scale Pilot Head ..... $ 4.60 could work in the A-10, but I don't think that there is anyway I can get the canopy off now.
Say, I have a Global Tequila Sunrise 25 (glow) I never built, about 2 years old in the box now. Noticed one guy here on the forum converted one to be "e powered". I think I may take a stab at it so I wrote him to ask what he used for the conversion. I have a much larger 45 Tequila Sunrise I fly Nitro, but a small electric might be fun too.
