Newer Heli radios will have CCPM. If your helicopter is CCPM it can not be flown with out it. Also, pots and switches may be configured better for adjustments on hovering trims. Also gyro programming, etc. I also prefer the smooth throttle ratchet. I like it better for planes too.

I like the JR 8103. My suggestion to any on buying a JR radio: If you fly planes and helis, buy a heli radio. It is easier to fly airplanes with the heli radio than helis with the aircraft radio.

Other manufacturers have good Heli radios that are competitive for price and features. All the manufacturers are making good products, so it is just a matter of preference as to brand.
