If I plan to use 4 elevon servos...two yéd together...will I have center matching problems on a pair on one side? I mean...will their centres be bang on target or will I have to use a device to get them to center at the same place. I know there are devices for JR and hitec that can do that. I plan to use either Hitec 5945 or JR 8411..whatever is available...

Thanks,
Anurag
