Thanks Gents for all this great info. I took stock of my parts after I resurrected an old TD 09 I use atop a power pod for an Olympic glider. I noticed I have two glo heads, and while I haven't burned any out, I started thinking of my options should I find myself in need of purchasing one. I enjoy modifying, customizing, tinkering, etc.... and your suggestions will go a long way towards that end.
Thanks again [8D]
