Loctite has agents in it that dissolves plastic. It reacts with something which makes it "mushy".

Loctite should only ever be used on metal to metal. Never near any plastic.

Message noted, lesson learned the hard way, now I'm grounded until more props show up in the mail, thinking CF this time. The question is weather I should fly 8 or 9 inch props.
I am a newb/ going on intermediate skills.

Which frame is it? Which motors? Which batteries?

If a 450+ size, 4S, CF definitely 9". If 3S, then 10".

Glad to see the problem with the GemFans breaking is solved. I use them on 4 multis and have never had the slightest problem with them. In fact, I've been amazed at just how tough they are. BTW, I have bought most of my props from Hobby King, but have bought a few elsewhere--no trouble with any of them.

is it solved? just rebuilt and waiting for props to come. wanted to just see how it flew. on second battery another prop cracked at hub. maybe i just have a bad batch. had a friend of mine who has been flying a very long time tighten the props and still broke. so i didn't over tighten.

They look like the same 9x4.7 that RC Timer is selling in the slow flys, RC Timer work out cheaper if you buy 4 pairs and you should have some spares so it is a good deal.

I'm really beginning to wonder if there are some bad GemFan blades out there. I know some of the issues can be explained by the use of loctite or over tightening, but it sounds like some are just breaking. I'm also wondering if someone is selling knockoff blades as GemFans. Again, all the GemFans I've ever bought from Hobby King have been very tough, and while I've broken some in crashes and bent others, I've never had one break at the hub for any reason. Thoughts?

Hmmmmmm, Could be, perhaps I'll contact the store I got these from and inquire if they have had other reports of them breaking if this is happening they should know.

well i got mine from rcdudes. it certainly is not their fault at all. after first one broke i thought might be over tighten. then i bought some 8mm washers to try and solve problem and not tighten to much. well second exploded in mid air on a windy day. tbs went down hard. lost both frames, naza and gps, and battery, rx three arms and 2 motors,luckily found go pro 3. well rebuilt and like i said waiting for carbon props just wanted to see if this thing flys. put some new balanced gemfans on. second battery had bad shake, landed and one prop was cracked at hub, now that i think about it all three that broke were green props. i run 2 green and 2 orange. have not broken one orange one yet. if anyone who has broken one can tell me what color would be great. on a side note does anyone know how to send in naza and gps to see if they can repair?

thanks
