Unfortunately, it's difficult to find a decent heli under $50. The one that comes to mind is the E-Sky Lama 4 series. They are 4-channel co-axial helis that have servos. They are going for about $85.00 You can also upgrade this heli to metal parts or a better motor in the future. I would rather save some more money to get a better heli which would also not be consider a toy like the ones you have suggested.



-Happy Flying !!!
