Paul,
Here are some pictures of the "Jerseyan" that should help.
Tack glue the top block in place, then mark the location of the "cheeks" as seen in the 2nd picture. Then contour the top of the block BEFORE gluing the "cheeks" permanently on the side of the nose.
Exhausting cooling air exists through a slot on the underside of the "cheek".
John refinished the same airplane twice. It was originally metalic blue with a map of New Jersey on the wing, Then it was repainted 2 more times in orange. The last time it was with a slightly reconfiguered nose, and a fuselage gear... but it was all the same airplane. The published version has the original nose that the airplane was best known for.
Interestingly, there was a 2nd "Jerseyan" built that was never flown in contests. It had an inverted engine, and a different rudder. It also flew well, but was given to a friend, and then lost.
I think that the pencil drawing of the 2nd version has been lost. I had it at one time but returned the drawing to John.
Again, if you send me your mailing address, I will send you a CD with many, many more pictures of both the construction, and actual "Jerseyans" that have been built.
