Hello Im having a hard time choosing my next radio, so out of these 3 I think i have it narrowed down to. flysky nb4+, sanwa mt-5, ko Propo ex-next. i plan on using the radio for onroad racing. the problem is i dont know too much about ko propo . all the radios look sweet. as a kid I did run ko propo back in the day . what your guys thoughts thanks

All 3 of those radios are excellent. I'd go with whatever you find the most comfortable.

I have ran all 3 of these brands over the years and I am currently settled into the NB4.


Deal breaker for the Sanwa (I had the M12) is it is extremely difficult to program, because of this I have made it a requirement that I will only use touch screen radios going forward for ease of programming. KO Propo is a solid radio (easy to program and great performance), I ran the EX-1, however the potentiometers went out within a couple years which left me disappointed.


I now have about 4 years experience with NB4


Pros: 16 hour use on a single charge, antennaless Rx, touch screen programming


Cons: touch screen difficult to see in direct sunlight


I think the newer NB4+ has a brighter screen making it more visible in sunlight though I haven't compared yet because my radio is still working great!


* Earlier this season the spring failed on my steering wheel, fairly simple to replace using a spare spring included originally.

* Last week the battery failed in the grip, also fairly easy to replace and I just happened to have a spare 18650 battery from a flashlight


final selling point:

I wonder why no Futaba is listed, the 4PM, 7PX and 10PX are awesome transmitters providing every need as all others you mentioned.

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.

mr Roelof do you have a Futaba remote? 4PM? the 7px and 10px are out of my price range

The 4PM is a good radio. The only problem I have with it is it doesn’t offer a drop down for the wheel like the radio it replaced which was the 4PV. Essentially they are pretty much the same.

I own a T7XC which is the stick version of the 7PX. The 4PM is just a cheaper version of the 7PX but for racing all the needs as also a super response which the others you mentioned also have. But yes, indeed a lack of positioning the steering wheel. If you look around you probably can find a 7PX with some discount.
