Here's a vid that might come in handy for any msr owners. It goes over common problems and how to fix them. http://www.youtube.com/watch?v=CEdTwXQB92c

I got the Helimax Cobra. The Rotor blades stick and it vibrates badly. Still new, no flights or crashes! The first Cobra had the same problem and It got battered around when I tried to lift off. I sent it in for repair and Helimax returned a new one!!! Great but the rotors stick on it too! I told them and they said send it in to be checked out! Tomorrow i'll send it in. I hope it works when it gets back here because it costs $15 postage and insurance, I can't afford to keep sending it back! What causes one blade to swing all the way in both directions and the other blade to go forward only part ways?
