What's the best Mhz to run with...
What's the best Tomy Bit-G Mhz to run with MS pro Mhz 27 and 49 at the same time? I've tried the 57 Mhz booster with success, wondering if the other Mhz would run as good (No interference).

as long as a person with a given frequency (say 45mhz) and a similar frequency (49mhz) are not BOTH very close to a 45 or 49mhz car, then you should be OK. A good idea is to stand at opposite ends of a track if your racing or something.

also the higher the frequency the further the range(in theory).

What ?
It is the other way around !
Low Freq need less power for same range ... since power is fixed bigger range could be achieved only by lower freq !
Problem : 27MHz already used by other Radio stuff, like CB , so the 27MHz could be the most noisy freq ... so could result the worst range ....

27MHz and 57 are under high interference because:
Transmitting at 27MHz means send an armonic at 54MHz
Transmitting at 57MHz means send an armonic at 28.5MHz
The power of the armonic is normaly produce a rage of few cm around: 20cm to 60cm !

lower frequency radio waves need more power to move through the air.
look at the new 3ghz cordless phones that can go 1000yds from the base but the old 900mhz ones would only go a few hundred feet.
this is the same principle.
