Guys, this stuff didn't just come out last week, people have been using it for years. Combat guys use it and it works well. The line usually comes with a booklet with instructions on knots that work well with their product. I have a few sets of lines in different sizes that have been in continuous use for about 6 years. I used a Palomar knot since it's so easy to get the lines exactly the right length and have never had a failure. I fly 10-15 sized planes on 10 lb. .008 line about 55', 35 size planes on 30 pound .012 line about 65', and 46 size on 40 lb. .015 at 70' The weight difference has to be experienced to be appreciated. I would suggest if you have never tried it and have any apprehension whatsoever, try it on a beater plane and see for yourself. I never met anyone who tried it and said they actually preferred steel in comparison. Some raise safety concerns, but they sure seem safer to me. They can get stepped on all day with no ill effects. They have been flying combat on them for years so there is some track record to refer back to. Trying is believing...

I figured you guys balanced them. I've talked to a few guys that told me they don't.  I don't know how they do it.

Yes, check balance as you knock the razor sharp edges off them.  So far I haven't found a wood prop with edges sharp enough to cut while flipping the prop as my son found out with an APC.

Yep, but I do keep urging Chris to bring out his .40VF Saturn. I loved to watch that thing fly, slow and precise. Not the blazing corners that Paul and Howard fly, and I miss the "slow-motion" pattern it showed. Bigger corner, thus downgraded. Don't get me wrong, I like the hard corner, but I still miss watching Chris flying his Saturn.  Steve
