On another forum there is a good thread about power use. It's mostly about GS planes, but there is good information anyway.
It has been stated there that you can loss up to 1/2v for every standard connector.
Robert from Smart-fly told me unless the jet is in the 40lb range standard set-ups are.
What you can do is solder the leads and get rid of the connectors. Dennis
