Just finished building a Trex500 ESP and have experienced its first hover..is it common for this helicopter to be so loud in flight? I have built all of the Trex sizes with the exception of this one and have never experienced noise like this in any of the others. Thanks for your imput.

Gear mesh too tight?

My 500 was really quiet.

They are considerably louder than a 450 though.

I literally never use the word literally right.

Some, but not all, of my 500's are pretty loud. Not really sure why. Seems like the higher the headspeed the noiser they are. They fly well, though.

Trex 450, 500, 600, 700
