    Is your problem ARF vs building, or the death of brick-and-mortar hobby shops? Where there's a real hobby store, you pays your money and you takes your toy home. I'm happy to be able to say...

    My wife has a pacemaker/ICD. I not only use RC transmitters, but I operate a 100 watt amateur transmitter both at home and in our vehicles. Never had a problem. YMMV.

    What they said... the problem with RC glow fuels is that the methanol is hydrophyllic -- it will absorb water right out of the air, diluting the fuel and robbing power. The nitromethane is actually...
