I'm not sure where to put this but:
While using line length to trim a model, how short can you get the lines before the lap times and shortness of the hemisphere makes things look well, wrong!
Jim Pollock, :!

Depends on the size of the plane. A half A looks fine on 30 foot lines. Paul Walker's B-17 looked a little cramped on 70 foot lines.

Isn't the minimum legal center to center (plane to handle) 60 feet for anything larger than class A?

I think the only minimum is the 42 feet for 1/2A if I remember right. I used to fly 1/2A on 35 X .012 cable until both cables broke when the plane hit the deck. Line length depends on how comfortable you are with the flight of the airplane.

Hi John. I was surprised enough by what you said that I went to the AMA site to check the CLPA rules. I "remembered" that the line length was dictated by engine displacement class and that back in the day we had a minimum length cl/cl of 60 feet. The rule book now just states the requirements for diameter based on weight and lists the lengths as 25 - 70 feet. You are of course correct. Thanks.

Also remember that is center of handle to center of the plane. On thE single engine planes, some people use the prop nut or spinner as COP. I remeber a couple of people having to cut their lines on PA one year. So check your event rules or what ever class your plane might fit.
