One of my rotor blades delaminated in flight today on my trex 600. Got it back on the ground fairly safely, but there was a definite pucker factor of 9.5. What would cause a failure like this? They are older Hirobo 600mm fiberglass balsa cored blades. They seemed in perfect shape. There was a loud slapping sound. sounded like a machine gun with a really high rate of fire. lol

also thinking about repairing this blade..... how bad of an idea is that?

Well ask yourself, is it worth the risk to you or your heli? Im sure you can pick up a good set on the fs forum cheap.

CWDoherty · 01-05-2014, 05:04 PM

yeah already have radix blades on order 10 minutes after it happened. lol. well theres one vote for "bad idea". I looked up the hirobo blades and they are $120+ bought this heli used, and it came with them. guess price doesnt = quality

Could have been a defect.

Definitely don't repair them. Very bad idea.

does sound like a bad idea now that i think about it, and why bother anyway? Do Hirobo blades have a history? i mean they were so easy to track, and and seemed like very high quality blades.

How cold was it when you where flying today? Where you really on it when it cut loose?

CWDoherty · 01-05-2014, 06:22 PM

not too cold. mid 20s and i was in a hover when it happened. The blade must have been damaged in a way that i didnt spot it. oh well fbg blades are next to woodies as far as im concerned. i know ill be much happier with the carbon radix blades that i will receive this week... hopefully thursday

. thanks for the input everyone!

I would just say wear and tear wood expansion contraction. wood is never fully stable and it expands and contracts unless fully sealed by wax or epoxy.
