I'll be using a Norvel. When you mention the line diameter, are we still talking about the standard 1/2a Dacron type string or wire?
I've never tried the fishing line but I did fly a friends model on it and it performed very well. He is an ex-Cox engineer and his engines perform very well by design, he's "into" 1/2A's. I believe the model i flew was powered by a Norvel or Wasp .061 and I flew the standard AMA Stunt pattern with it with no problems.
I used the stranded Sig .008 steel wire cable when sport flying 1/2A's, and when flying Speed events we were required to use certain sizes of solid wire. .010 was the last I remember.
The Norvel is a great engine, the Wasp is too. I've only used the R/C version for Scale models but they're very user friendly.
