Strange. I'm getting a slight chirping sound from my mini titan. depending on which way it is pointing - it can be more pronounced or can't hear it at all. It just started like 5 flights ago.

belt tension seems to be fine.

Are you using the stock motor?

I'm using the Align 430L motor.

I'm thinking it may be the tail control rod. perhaps it is vibrating and rubbing along the guide. i'll move the guide around and see what happens.

It sounds like it is a main baring.

Mine chirped because of the stock motor, replaced it with a scorpion and it went away. Happened after 100 or so flights.

Who raised the ground since I took off?

I was also having that sound with titan motor, switched to scorpion and its gone. I did replace the bearing of the stock motor to ceramic but didn't fix it. I think its the shaft wearing out.

It was the tail control guide that was making the sound. the control rod was vibrating up against the control guide. Basically, I turned the control guide so that it was putting some slight pressure up against the control rod - that prevented vibrations.

it's how crickets chirp - by rubbing their legs.
