Hi Bob,

  

   That was me that asked about the mos-fet.  I had made out my shopping list of parts on Mouser, and when it was almost finished, I got to the IRFP 3703.  No matter how hard I tried, I just couldn't come up with one that they carry.

   Since it took me quite awhile to fill out the Mouser shopping cart, I was wondering if you knew of a compatible version of the 3703 that Mouser sells.

 PS.  I did find it on Digikey, but I was hoping to get everything from one vendor.  Thnx

Is it true that IVO insists that the supplied wiring to the prop not be 

shortened as it is part of the current limiting to protect the motor gears?

		   This is why I like the idea of the electronic limiting feature of

 Bob's circuit.  The reed switch is a huge improvement over guessing

 where the prop is set, or using the provided CB as the ultimate

 'stop'.  It lets the user know when the limit is reached, but doesn't

 prevent abuse (intentional or inadvertent).  The electronic CB

 prevents the abuse, and can only help improve the life of the gear

 train and electric motor.
