38-in. Jetco Rearwin Speedster

Necro thread, eh? Ok.. Ok.. still funny. While I've been building models for 61? years, I haven't posted much. I tend to read the ones of interest. But.. with grand-kids clamoring to fly, I'm slowly putting planes back in the air.. mostly slow easy flyers.. but this one will be for me. It looks like the "A" sheet was basically antique radio install info. While I DID have a Citizen-Ship TX with vacuum tubes in it, and flew several on escapements.. I "might" (???) have to pass. When 4 servos now weigh less than the escapement rubber, seems to be a no-brainer.

Has anyone put brushless in one of these.. or will that word be stricken from this forum?? (Yes, I loved my oh four nines for sure!). But I have to admit.. the ones I've used so far, are slick! Suggestions welcome.

Thanks! Jerry
