Title: NEW TYPE OF CONTROL LINE FLYING
Post by: LARRY RICE on June 03, 2011, 07:44:39 PM

  I have always been interested in how control line flying survived the war years.  I found out about "Whip Powered Control Line" a few years ago and we produce a few kits of that type.  Then I learned about rubber powered control line.  Companies line Scientific Models produced control line kits that operated on rubber power.  When I got flight reports back on our new free flight rubber powered kit (Golden Falcon) of over 2 minute flights it all seemed possibable.  We will be testing this out with a Golden Falcon and I am interested in what you think about it.  I am also looking for ANY plans for Rubber Powered control line models.

Thank You
Larry

Guillows, maybe? Seems like they were involved in everything - Model Aviation.

An Old Timer high wing (F/F) kit with mods for C/L sounds like a nice project for somebody. It would have to be light, no dihedral with lots of rudder for line tension. Centrifugal force just wouldn't be there at that speed.

I have plans, maybe in a Flying Aces magazine, for a rubber powered control line model.  I saw, at a distance, a rubber powered CL model fly at a past Vintage Stunt contest.  I thought the same one I have plans for. As I recall it made maybe about a lap and a half before running out of power.

I also have plans somewhere for a freeflight model converted to control line.  This kind of airplane was called a "Goat".  The St Louis SAM club has a contest in October which includes CL slow flight.  It requires a Goat airplane, but I don't know the rules beyond that.  I think winning speeds are in the 20 MPH range.

I've never built a successful rubber powered airplane, so what do I know?  I think one would have to go to a geared motor to get a long enough motor run to be much fun. 

Anyway, I'll see if I can find the plans and will send them if I do.

This is the model we will be testing it on, the "Golden Falcon".

There is a huge British literature on round-the-pole flying with rubber powered airplanes.  People have also done it with 1/2A airplanes.  I have an article on R/C control line with 020 engine.  It used a receiver and servo on a rotating disc on top of a pole, The servo acting as the control handle as we think of it.

There's plans on the internet for Stanzel Tiger Shark (with engine) and Shark P-60 (rubber): "G Line" speed planes. I think G Line does not give all that much control.

I went crazy browsing... and found "Complete Construction Data That Will Enable You to Build the Fastest
Model in the World" from 1936, on theplanpage.

Not control line at all but a rubber powered design that went up to 60 mph.

Article and plan in the attached PDF

 Larry, I found the rubber powered CL model in the first magazine I looked at.  Flying Aces, June 1942.  I'll send you the magazine assuming I can find your mailing address (shouldn't be too hard).
