60' is pretty standard for that size model. The AMA website has guidelines for line diameter I believe, maybe under the combat rules which I have not read in years, or for sure in the stunt rules. I personally would use 0.018" with the .40 size engine. If that prop is an old white or yellow prop I would pitch it and get a new APC prop. Nylon ages and is failure prone.

That is sure to be a very fast combination! A Flite Streak with a 40 and a 9x7 prop would be a screamer for sure! Way too much for me!

As to line size, I agree that .018 x 60 ft would be about right. If it were mine though, I would slow it down a bit with a .25 and run .015 x 60 ft for stunt flying. Probably run a 10x4 or 10x5 prop depending on the engine.

Have fun!

I've never tried it but thought it would be fun to set up a control line plane with RC hidden inside. Put on a show at the RC field make a two or three rounds and have a buddy with a radio flip a release switch; fly off into the wild blue then turn around and come back; do some loops and land it. LOL

It has been done decades ago. I remember it in a magazine. It was mentioned that another line was attached to the other wingtip so it was easier to fly without spiralling in. If you try it, get video.!!!!

Chuck and PaulWells -
AMA's rules are available on their site. The current line specs are in Control Line General section. They are general standards. Specific contest event rules require lines that match that events realities. E,g., Speed, with small, heavy, fast and 'vastly overpowered' models...Racing, with plenty of pull in flight... Carrier, with speed and weight involved, also names suitable line specs.
The specs in the General Section cover Precision Aerobatics, and are usable for non-competition and general sport CL flying. Current rules do not require metal lines standards except for contest event flying, necessary material specs are spelled out where Contest event conditions make it necessary.

For a Flite Streak with a heavy, high-power engine, 60- feet may feel a bit crowded, but is a practical size for trying to find a field...

Have fun!!
