Thanks, Dan, Floyd, Steve,
Yes, I ended up getting a copy of the plan from the AMA. And, I suspected that it was probably classed as a gutless wonder. 60+ years ago when I moved from rubber powered and gliders to the wonderful world of engines, the only thing I ever saw or used were Cox and Wen-Mac engines that I scavenged from plastic ARF control-line models that didn't survive their figure 9's or across the top wingovers. IIRC, the only Infant I ever saw referenced was in model mags once I started cutting grass and had a dollar or two. Another clue here is that the Tic Tak is quite small, ~24" span. Quite likely I'll not be able to find an Infant that would actually run, even if a suitable glow plug could be located. But I thought I'd at least give it a shot.
Thanks,
Jim Howell
