RE: Futaba 7C CAP
are you using the flapperon function or are you free mixing it? If you free mix it it won't work since futaba :uhhuh: kindly left out the ability to trim the mixed channel. As far as the flaperon function it's been hit or miss for everything to match up. I usually have to find a couple servos that match each other perfectly.
other wise. make sure the mix is active and flap trim is active. the percentages are 100% or what ever you want. I usually just reset the mix if it's acting too goofy. Unfortunately you have to reset the entire model
otherwise the specifics are on page 43 and 44
