The original main rotor blades that came with my Hummingbird were made of bad material. I had previously read how others were phrasing how strong the blades were, but mine were so brittle the first glancing blow against the floor shattered one. I put one of the blades from my crash kit on to replace it, but it had less pitch then other remaining original, so I thought I should try and twist some of the pitch out of the original, but as soon as I started to twist it, it snapped apart in my hand.
I kept the pieces and later when I had a very hard wack that took a big chip out of one of the replacement blade I was able to do some testing of the pieces of both the original blades and one of the replacement blades. It was very obvious that there was some sort of batch or possibly age problem with the original blades, because they broke apart like egg shells compared to the one I got out of the crash kit. |
So I made 2 v shape leg from piano wire that fit on the outside frame and I used cable ties to keep them in place. So word of advise, Don't glued the leg to the main body.
I think one of the leg was broken on the first flight. I didn't even crashed that hard maybe just bad material. I mnaged to fix it last night using a plastic pushrod from left over aeroplane material. I pushed 2 parts of the leg into a plastic pushrod and its fixed.
