Is the 500mx that much better then the 500m? I have had my 500m for a while probably over 100+ flights but I think the bearings are going out. How can I tell for sure? It makes a whinning noise once in a while and I had the main gear out the other day and ran just the motor up and the motor have a fair amout of high frequency vibration through the whole frame but I wasnt sure if it was normal as I have never done this before and also when I touch the can as it spins I can tell it is slightly out of round and vibrates as it turns so I am thinking it is the bearings also the motor has 1-2mm up and down play but it has had this forever. Do I have to take it out of the heli to tell for sure?

One more thing if the motor bearings where starting to go out how would it affect the heli in flight tail kicks, head bobbing,shaking etc or no difference at all?

and the blonde said "RECTUM, Hell damn near killed em!!"
