I run the stock radio system in my RC18MT and it doesn't glitch a bit. Many will tell you that stock radio systems (AM especially) isn't good when running brushless, but I have experience no glitching, clogging or anything. But, I'm sure I'll experience that sometime.
What would be safest would be to go with some sort of FM radio system or if you have the money, 2.4GHz Spektrum.
Futaba 2PL:
$84.99.
Futaba 3PM:
$109.99.
Airtronics Spread Spectrum MX3:
$179.99.
Spektrum DX2.0:
$169.99.
Spektrum DX3.0:
$249.99.
As you can see, FM is quite a bit cheaper than the spread Spectrum/Spektrum radios, but, with price comes quality and reliability.
