model memory was upgraded from 30 to 50 models, 9503 added a backlight screen and a timer that turns on with movement of the throttle stick. pretty much the same transmitter. both will work as a buddy box with all other JR and spektrum transmitters.

I have the X9303 and have reviewed the manual for the X9503. As stated above, additional model memory, back lighted screen and an additional way to activate the timer(the X9303 has a timer function as well). Other than that, the same.

The disadvantage of the timer on the throttle is that it can/may be activated during your engine start procedure as you move the throttle stick. This may not be when you want your timer to start or want to have to do a timer reset to get it back to zero.

The DX8 is newer, so it offers telemetry. Also, it has triple rates instead of dual rates when not using flight modes. except for these advantages, the 9503 is a better radio, offers more channels, memory. Both offer model match and servo sync, and BNF. Servo sync is particularly wonderful, if you have two servos on one surface, such as the elevator, both servos will receive signal at exactly the same time. this is really imporotant on elevators for a 3D plane or cyclic servos on a heli.

The DX8 also has the very fast 11ms on the primary flight controls but holding both in your hands and the DX8 will feel like a toy compared to the 9503
