NB4+ over the MT5. I initially purchased the MT5 to replace a Spektrum DX5C. The only other radio I had at the time was the M17. I had invested in Sanwa receivers and used their servos.
The MT5 interface is pretty bad. The NB4+ has so many features for its price point. The receivers are more affordable.
I also have 10PX and M17. 10PX is my go to radio with the NB4+ becoming the second. That may be because the M17 has become my son’s radio of choice.
