I fly a Fancherized Twister on 65' lines.  That's probably a bit long, but I put it on those lines and never felt a need to try something shorter.

Conventional wisdom would put your line length between 60' and 62' if you're using a Schnueurle-ported 36 to 46 sized engine.

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

try three sizes. 58', 60', and 62'. Try each length with the engine set to where its happy. you will want anywhere from a 5.2 second lap to a 5.5 second lap. On my Nobler, i found it flies exactly the lap time i need on 60' lines.

Mr. Saunders has it right.  If you can make it work on the longer lines (60'), Lucky you. 

My Nobler is competitive at 57.5 foot lines,  eyelet to eyelet.

Aerotiger 36, 43 Oz.   Nice line tension there.

I think Bret said one time to run the shortest lines you feel comfortable with. My 52 version Nobler flew well with a Fox 35 on 58' eye to eye.

I don't think any of those things have a great impact on the line length choices.

I believe it has a lot to do with engine size and power/weight ratio. The KISS! (Fancherized Twister) at 47 oz with a Magnum XLS .36 was a lot better on 58' i2i than 59' i2i. After I gave it to Tim, he tried to fly it on 65' lines, I bet! It didn't last long after that.  LL~ Steve
