RE: Any info on this aircraft??
My first model too. My parents friend bought it for me for Christmas, I was four years old. I flew it when I was 5 or 6 with my dad's help. Later I turned it into a racer and clipped the wings, added a complete bottom wing skin and a little Sig canopy and a Cox Tee Dee 049! I still have it as well as a stock example I found on eBay.
It is actually called the Wen Mac Day Fighter and has an ejecting pilot with his parachute stowed in the area behind the seat.
All Wen Mac engines do well with 30 percent nitro Cox fuel and a 5x3 fibreglass gray Cox propeller.
Check out the Yahoo Groups 049 Collector. There is a very complete photo section of about every plastic RTF model ever produced.
