HA! You would have to ask that question wouldn't you? At the time of the picture the Lit' Toni had a Dub Jett 90 in it with two muffler extenders. I never could get that DJ to be really reliable with that configuration, and because the model is only flown occasionally for sport flying, I placed a ST 90 in it. Side mounted the ST 90 is flawless. It only took a dozen flights on that machine until I had to rebuild and beef up the firewall structure. This was an early ARF kit of the Toni, and it was not, IMO, too well put together in the front.

The old picture was back in '73, at a local stunt meet in the Chicago area where it placed 1st. To your question, at that time it was using a George Aldrich Special Super Tigre 40 which was a super stunt engine. There were 3 models of that line. My first was smaller for a Fox .35. I later switched to a Veco 35, which was also excellent. It won a few trophies. The pictured model, I added some more wing, extended fuselage and added more sweep in the main wing. It was an outstanding stunter. #3 had a couple changes such as a stabilator. WRONG DESIGN DECISION. [:@] Now I know why, but then I did not. That machine had a mind of its own. The first Mig was initially flown in 1969, and into 71. The second (pictured) in 71-73 and the 3rd in late 72-73 but not much. By '73 I was too far wrapped up in RC and sold out my CL stuff. Another planned project is to build a revised #3 this winter and see how goes it. I will use a Fox .40 stunt engine or maybe a ST .45. I have some .51 and .56s that can be retrofitted to do a decent job of stunt.

Speaking of engines, I was asked to fly a preproduction McCoy 40, that gray-case one, at the '71 NATs. Possibly my only chance to ever get in the top 10 at a NATS. BIG MISTAKE! Only had 4 practice flights before the first official. It was going good, about 6.5 minutes on Fox Superfuel. I was doing a fair job for me. I knew I had a barn-burner flight going. Then just after the loop of the 4-leaf while going over the top, that #$?^%!* went into Rat Race lean and I got 12 minutes of flight time. Had I just got the 25 pattern points OR a decent landing for same, I would have placed 2nd in my circle given a decent 2nd flight. Of course I set too rich for 2nd flight and wallowed all over the sky. Testors did not ask for any comments on their new entry into the CL Stunt circles. However that engine was very good in RC. It had a K&B Series 70 piston, dykes ring and rod in it.
