Ready to order a set of Tom Morris lines. Going with the 7 strand but not too sure on the Diameter and the length....
Hoping to use for both the Ring Master and a Twister.
thoughts and opinions?

.015 dia. The Ringmaster likes 58 footers the Twister likes at least 60. It depends on which engines you are using. Also buying bulk lines and tieing them yourself will save some money.

Cool deal.. Thanks Perry!

Ringmaster will be with a OS25 and Twister with a Enya 35

Definitely .015" seven strand from MBS if you're buying bulk.
TM wants to know eyelet to eyelet length so figure 60' for the ringmaster minus the handle and the plane center to lead out eyelet and you've got it, about 57'? The twister might be best on 63' handle to thrust line but it has a longer wing still, a bit of a compromise.
I take so long to get the exact neutral on the handle that its worth it to get a dedicated handle and line set for each airplane. One less thing to do at the field.

0.015 seven-strand. Make up sets of 59, 60, 61, and 62 (or start with 62 and work down). Start with about 60' eyelet-to-eyelet on both, retrim as you experiment with the length. Even a foot can make a huge difference. If you only want one set, pick 60', and optimize it for that.
Assuming the a 25LA or FP, the problem with the Ringmaster will be speed. Even with 4" of pitch it will be a bat out of hades if the engine is running in the sweet spot, and probably inconsistent of you try to needle it down to a reasonable speed. In this case, either the "old" 25LA or, dare I say it, reduced venturi (to kill some power while permitting it to run in the preferred 2-stroke). You still don't want an ST spraybar, we have done that experiment and it's too much power lost. You might end up wanting longer lines.
If this is the older Enya 35 baffle piston engine, you will end up with shorter lines, maybe 58 feet. It's not as extreme as it would be with a Fox (where I would start with maybe 58 and expect to work down to 56') but the same issue.

Dedicated handle and lines for each plane is absolutely the way to go. I can't imagine trying to do any of the tricks without a VERY good neutral setting. Saves fuel wasted while flying out a tank or more with a bad neutral. Doing tricks with a bad neutral is risking your plane. That doesn't save money either! Maximize the gains you can make from the time you have for flying. H^^ Steve

Lines are easy to make, and cheap if you get stuff in bulk from MBS. Hard point handles aren't that bad to make, either, and you can customize them the way you want.

May split the difference and get 60' to start. Im not competition ready and just wanna get in the air for now to get the feel of things again..
-
Do really appreciate the advice and wisdom yall!
-
Way to go James, remember KISS(keep it simple Stupid) until you get to point you are ready to start getting serious. Right now I have one set of lines and handle that I am using on four different planes. Only difference is the up line clip on the planes. Also I do have more than one set of lines. H^^

yep yep.
I do plan on learning the science of all this. I do wanna fly stunt eventually. and maybe one day fly the pattern lol
But for now just to get in the air and enjoy it.
