I have a question for everyone.I got at new rx 18 board recently for my Tiger tank.I swapped it out with the one that came with it to see if it would make a difference with the sound.Well it did make a difference the machine gun sounded different,the start up and idle sounds where different,the cannon sound sound was stronger and more robust sounding.But heres where it got interesting when giving the tank throttle all it would do is let out high pitch whining noise when it started moving and calm done after givingit full throttle.So I was wondering if anyone else has experineced the phenomon.

The one on the left in the picture is the new one and the one on the right is the one that came in the tank.I noticed the new one has an extra board in it,could this be the reason I wonder.

Thanks
