The answer is: maybe.
Seriously though, it depends. If the problem lies with the radio itself being too sensitive or the noise filtering is inadequate, then yeah, another radio may help. But if the problem lies with the setup, then another radio probably won't work (or work just a little better).
I would try looking at your wiring setup and maybe moving your antenna first.
Or, take your vehicle to the LHS, tell them your problem, and see if they will let you try another setup. The guys behind the counter probably have all sorts of systems in their vehicles and might let you try one out there.
You have to remember that radios are receiving signals in the
milli-watt range, while the brushless systems are drawing
hundreds of watts. So, signal wash out is possible.
