I've got a Babe Bee .049 that I am going to build a CL model for. I was thinking of using a foam wing with about a 19" span and 5.5" chord. It would have tail booms similar to a Goldberg Lil' Satan.

Would that be about the right size for a Babe Bee?

Actually, I am in the planning stages-about to do about the same thing. I have some left over (not perfect) fully symetrical airfoiled wing cores from my Caudron project, an extra carbon fiber boom and a worn out Caliente motor(They begin life as control line combat motors).
Have been flying a lot of control line lately, and want something to bang around with, maybe even train a couple of the guys who have been interested lately.......

By way of comparison, the wing I am using will be closer to 30" span, and have about 170 square inches......

FWIW most of the slab wing 1/2A trainers (like the brodak trainer, sig deweybird, etc) have about a 22" wingspan, 5" chord and are decent flyers with a 1/2A reed engine.

Dick Sarpolus has done TONS of 1/2A control line profile planes over the past number of years in Flying Models magazine. Might be cool to look up a few and see what he uses for approx. dims.

Myself, I am making up some coroplast trainers that were published in our MAAC model aviation magazine (our version of the AMA) this past year. Like a small combat wing and indestructable! Thats why I needed the nylon props also.

I'm Canadain too. Do you recall which issues of Model Aviation Canada have the articles?

Not exactly (I can check later) but within the last 5 or 6 issues is the one article on the "manwin" trainer, its a one page article and a one page drawing.

I have been working with kids of all ages since the 60's, practically all with Cox engines. A Baby Bee, Golden Bee or Black Widow will happily pull a 24 inch span slab wing, but you may be pushing it with a built up, or foam wing any larger than that. I have flown 1/2A combat planes up to 24 inches, but they get a little squirrelly larger than that. That is on 35 foot .008 lines.

Model Aviation Canada, Dec. 2002.

This U/C combat trained was designed and kitted by a local modeler in Victoria, B.C. about 15 years ago and found it's way to Manitoba by way of Ken Thomas, a past ZD who moved there to works for Air Canada.

The origional name was "Corobat", is instructable and lot of fun.
