My new KDS 5.5 is flying great but is making a
Strange noise that I'm just not used to hearing.
I'm hoping it's nothing wrong. Everything looks
Good as far as I can see. I'm not used to the belt drive
On a larger heli. Could be the belt I'm hearing. Not
Sure. Should I put something on the belt ? Oil,
Lube etc ? Do these helis sound a bit different
Than a regular 550 class T-tube heli. ? Any
Suggestions would be appreciated. I know it
Would be almost impossible to diagnose without
Hearing it fly but thought I would ask a few questions.

Thanks

Brandon

u would have to be a little more specific or try hovering it first cause i dont hear anything besides blades and motor and whipping of the tail on rudder input ...

OK. I feel like a idiot. I figured out my problem and the strange noise. I was looking over the heli and I noticed I had forgot to tighten the two main collars that are around the main shaft. If, you have a Agile, you know what I am talking about. I put them in place and tightened them and everything was great with no noise. Thanks for your help.

Was the sound a real high frequency sound? Today, when I brought her back for landing, I started hear a high frequency sound. Belt is fine, no fray's, but I checked it and it was loose. I'm at probably flight 20 - so things are loosening up. Is that the sound, a high frequency sound from a loose drive belt?
