I am flying on 60" lines but have some new 70s" I plan to cut down a bit. Line tension is not a problem, it pulls like hell! I am using Wildcat 20-20 synthetic, no castor. What will castor do for me? I also have a F and A3 plug ready to try.

Yesterday I crashed my Shark .15 (Norvel .15 with the carb wired open) with minimal damage, in front of about 15 people, it flys way to fast too, all that is in another post somewhere. I will have to learn with the Shark .15 before I will try the Nobler again but I'm going to have it ready.
