I have some strange vibration coming from the Gears on my heli. They wobble like mad. Heli has about 40 flights and has never had a crash/incident. And It has not been in stunt mode.

Anyone else have this issue? Does the main gear need to be replaced? Is the bottom shaft bent?

Please help as this is my first collective pitch heli

Check your motor bearings, mine lost the bearing after about 25 flights... as far as the waving lines in your video, any vibration will cause that, the camera needs to be mount solid to eliminate the waves.

I crashed my b450 the first time out breaking the woodies, bending the flybar, stripped the main gear and the front servo gears. While I was waiting for parts I got an mcpx v2 and a mqx to fly around. The mcpx is squirrely and I can't fly it in the house in tight quarters. I've spent a lot of hours in rf6 but sadly no blade models are available.

Ok, so after taking Both gears out (they come out in one piece) and looking at it, i noticed that there was something cracked inside the gear where the shaft goes. I took it out and sure enough the one way bearing shaft was cracked.

Here is the link to the part: http://www.e-fliterc.com/Products/De...ProdID=BLH1649

I installed and there is no more wobble in the gear and vibration is just about gone.

Just pulled the trigger on the 450. Ray cut 20 bucks off the price so I got out of the taxes I guess. May be a couple weeks befor I get it in the air. I sold a house and bought one so have been and will be quite busy.

I pulled the trigger on one too; should be here later this week (bought used, ie, crash-worthy )

Can't wait!

Also, I set up my Tx to the dx8 instruction that came with the heli but I was checking range of motion in hold mode and it doesn't look like I have much pos. pitch. Looks like I have more than enough neg. maybe I have something backwards.

BNF no longer available @ Horizon Hobby? Maybe the end of this helis life with the newer helis coming out? I might buy another BNF as a "parts spare" because I like this bird so much.



@ JimBaker, nice video! When you pull those loops are you only using elevator or a combo of cyclic and elevator? I am able to do loops on the sim using only elevator. ( Not quite ready to try them in real life tho)
