RC ERA C189 MD500 in MH-6 Trim 

Hi. This is what I went through with this heli. I bought this along with a c129, both branded as rcera. When I tried to fly the md500, it went crazy and did the flyaway up, forward, and both sideways. I took it apart and found that mechanically it is perfectly sound. However I found that the controllers for the md500 and c129 were almost identical, so I tried the md500 with the c129 controller and it worked! Perfectly! MY md500 is unflyable with it's own controller, but flies absolutely perfect with the controller from the c129. The differences between the two controllers are minor, meaning I loose the Kill (stop) button and I loose the auto land function with the c129 controller, but consider that a good trade to be able to fly my md500 perfectly, every time now.

Sweet, reminds me of the Blue Thunder movie shootout. I am not sure if that is the same model in the movie. Looks like it.

Those are so cool!

Great video! You seem to have this heli figured out wonder if you might know what would cause drift to the right (pitch to starboard) ? Every time I get my US Coast Guard version in air it starts to drift/ pitch to the right and before I can even attempt to trim it's off in a bush or something, any ideas? I'd appreciate any advice from a pro thanks 👍

Has and problems where all of a sudden it just takes off and does its own thing?

are you pulling back on the stick to stop?
