thanks David for your reply, but then that last statment you made makes me still think about the buffered extension

"The latest firmware update allows selection of digital or analogue servos, futher refining servo performance"

If I have a buffered extension wire inline to a digital servo, would it make any problems? Is the new firmware in the weatronic just to be that more precise in programming it, or will it change anything that the westronic will output to the servo. If it were just analog I wouldn't worry about it at all.

The reason I ask is that I like using buffered extensions over clamp on mags, maybe overkill, but has worked for me for years without any problems so far.

I am leaning toward the full blown version with gps, because of the extras that it brings to see all the data afterwards.

thanks
Paul
