These are driven by its own engine, or by both thru a gear box. In the former case, a dead engine means contra="0", in the latter case its "1" and with half the horses, a dead one spooling up or a live one being killed, slides the contra setting from "1" to "0" or "-0" or vice versa, with the torque sliding from '0' to '1' or '-1'. ;-) -- ..med vennlig hilsen = with Kind Regards from Arnt... ;-) ...with a number of polar bear hunters in his ancestry... Scenarios always come in sets of three: best case, worst case, and just in case. _______________________________________________ Flightgear-flightmodel mailing list [email protected] http://mail.flightgear.org/mailman/listinfo/flightgear-flightmodel 2f585eeea02e2c79d7b1d8c4963bae2d
