Hey guys,
So I figured I would practise some side orientation hovering in the house tonight. After flying out 4 batteries I noticed my tx was getting very low reading 9.6v. I figured, i'd fly out my last 2 batteries. When I was done, I decided I would put in a couple drops of oil on the motors and work them in a bit. I had one more battery sitting at storage charge so I figured, I would plug it in spool it up quickly to listen to see how much quieter the motors would be. As I got it into a hovor I had major vibs on my tail it was shaking so bad, the skids started to come loose. Well, now I was perplexed cause it just flew fine 2 minutes ago. So, as usual, I started seaching threads to see if I could try and figure out what was happening. Did the usual check the main gear, pulled the shaft off to see if it was split, checked the bearings and so forth. I figured I might as well plug in my tx to recharge it too. Then I thought maybe my servos are getting really dirty and causing some issues. Unplugged my tx, powered up the mcpx and watched the servos. No glitches, no problems. I noted the tx was now up to 9.9v from down to 9.4v. I figured what the heck, spool up the mcpx again and see what happens. Wouldn't you know it, major tail vibe gone! I fiugred, I'd charge up another battery to test my findings. This time my tx was up to 10.6v and behold, no vibes.
So, lesson here is don't let your tx fall that low even if you're just hovering around in your house 5 feet away from the heli. I figured the tx must not been able to give a steady command and it showed up as a quick fast vibe on the tail.
Anyone able to explain the theory behind it or experienced something like this before? I'm using a DX7.
