I'd be happy to give you details of the 60' 1/2 A flight. The Medallion powered 150 Ringmaster was actually flown on 41' lines. It was only the sheet wing RM that was flown on 60' lines. This was the first time I tried it just to see if it was possible and it went a lot better than I thought it would. I made three or four flights and there was very little wind of course.

The engine had 5 degrees right thrust and the rudder was offset 1/4". There was three pennies under the right wing tip and the center of the leadouts were moved back 1 3/4' from the C/G. The engine was a very good running Goldenbee, dual transfer ports, no boost ports, perfect compression and .024 subport induction. The intake tract was not drilled out but the subport induction was obviously modified by somebody. Sig 25%, low compression head, 5-3 cox prop yielded 19000 when first started and dropped to high 18s when hot. Best GoldenBee I've had.

Surprisingly it flew better than I thought it would on the 60 feet of 5lb. spectra. I found it would stay out on the lines fairly good doing wingovers, large and small loops, lazy eights and PA eights and maybe I did a couple of inverted laps. It absolutely surprised me that it did that good but flying with 5 lb spectra is almost like flying with no lines.

60' lines.  Spyder wire I would think?

Three cheers for Little Toot!

It was 5 lb spectra

Thanks, 60' lines has got to reduce the dizzies, right? Also it would seem that flights would be much more realistic with thin almost invisible lines. But control with 1/2A could be an issue.

First of all congratulations on achieving those kinds of flights on 1/2 A CL... I would have thought it would be good to just make laps much less wring it out!

Also, Thanks for sharing the numbers.... Very interesting.....Looks like offsets were tweaked a bit and maybe a bit more wing tip weight.... Light lines and a strong engine....
I haven’t flown CL in a long time but have nice memories of it.... Might be fun to try something on longer lines (slower lap times  Very Happy )

Nice running Golden Bee and great info on it.... I don’t have a GB but a handful of Babe Bees and a stunt tank or two.... Good numbers to shoot for....

Thanks again

Yes, everything you said is right. 60' lines really isn't practical because it has to be near calm winds and there's kind of a loose sloppy feel to the controls. I normally fly my 1/2 As on 38' or 41' of 10 lb spectra.

The Little Toot was built in 1973.

Yes, that Little Toot is wonderful, stuck a nostalgic nerve in me. I wish I had saved all my 1/2A bipes.
