I know that the instructions say to glue the ends on but I just slapped my blades on without glueing or balancing today to test out my R50 V2. No shakes or anything at all. I have heard that Alan does not balance his wood blades, but is it ok to not glue the ends? I will be using fiberglass or the carbon ones later on.

If they are on for one flight or 100 they must be glued and balanced!!!

Yeah good idea, you need to glue them. Also, the epoxy that comes with the raptor kit smells like crap so do it in a well ventilated area.

Glue

I too didn't think the glue was nescessary, until I saw first hand a friends blade come flying off right in front of me. He had been flying helis for years and had never glued them and never had a problem. He was flying around, and came down a little fast, causing a slight overspeed. I noticed it, but didn't think anything of it. About 30 seconds later, one of the blade roots let go, and the blade went flying. Luckinly, it went away from us. It obviously resulted in a crash. I think Ctseaplane has a pic of the blade. I make sure I glue whatver wood blades I use now.

Glued my woodies with epoxy. I hate balancing blades. It was fun when I first set up my first heli, but now I rather go fly.

Always glue your blade's end, you can save a life.

I saw one blade breaking and it went fast and away, luckely it didn't hit a person, the can kill.

And do bance them, it avoids vibration, giving longer life to the bearings,

The Raptor instructions are quite specific that the blade cuffs should be glued, so if you failed to so and then caused injury to a third party, I suspect that the lawyers would have a field day with you.

Blades

I know I am a law student. Most of my professors like to go to Japanese steak houses where they put on the knife shows and wait for a knife to slip. Ouch!

Lost a TSK 60 a few years ago due to a blade root faluire because i didn't glue the root. Bent the mainshaft and chopped the boom off, the out of balance condition destroyed the switch and locked the engine at full throttle. All this BEFORE it hit the ground. The turf mearly insured that all was lost. Found the thrown blade stuck in the ground about 50 yards away parallel to the flight line. That loss was so dissapointing that i threw it in the corner and didn't fly a chopper again for quite a while. Think about the physics invovled, lots of shear stress on the screws in the blade cuffs, the glue helps spread that stress out across a much larger area
take care
