Re: Homebrew Rotator Question



Check whether your local library has "The Satellite Experimenter's 
Handbook"...  if not, they can probably get it for you thru interlibrary 
loan.  There was an article in there detailing a couple of techniques for 
adding position pots to that type of rotor.  The simplest is the bracket and 
weighted arm that you mentioned.  Another possibility would be belt-driven, 
off the crossboom.  Adding something to the gear train internally would be 
much more complex...
