Hi Guys, If you go to the Futaba web site,under search FAQ, You will probably find it thereI have done it with my futaba 9C using a 7 channel receiver using a pmix,and you can reverse the servos independently so they go in the right direction,+or - 100%. If your not sure []copy your model to a second model,Say model 10,and experiment with that second model so in case you screw up the original model is still there,and you can delete the screwed up model under parameters. If it is good just add the name and your done.I hope that helps you out,Bye ED
