Re: Dale Kirn's 290 Special
Dale was always thinking of ways to get kids into Speed events at contests and the Nationals. He created the 1/2A Proto and later the 1/2A Profile Proto Speed events. Proto was a small sized version of B Proto with 29's which was sort of a follow-on after the loss of B Team Race to Rat Race in the early 60's.
This model was a 1/2A Proto model that didn't need a pan, fancy carving skills, etc of most 1/2A Proto designs. The simple sheet metal and bolt-on aspect of the motor mounting was to help kids see a simple soultion to a contest model, and use the engine out of their Mustang or P-40, Stuka, etc. Cool concept.

Looks like She really likes that Chipmunk
Anybody happen to have the rest of the article? I'd be interested in prop recommendations and of course flying tips and whatever else there may be.

Kari, the plan references a Grish 5.5" x 4" L/H was used.. which is contradictory to the article's mention of a Cox 6 x 3.. which apparently was for independent engine tests by the magazine.
Re: Dale Kirn's 290 Special
Thanks Roddie. I thought I saw a recommended prop size somewhere and looked long and hard at the article text but somehow missed that.
On the right column of page 13 there is a hint about using a L/H prop too.
