fx61, apm 2.5 and futaba 8fgs configuration.

Posted by Adam Eng. on March 28, 2014 at 5:12am

hi

i have an issue i am not sure how to solve. the problem is the pitch and roll reversed issue.

on the mission planner if i pitch or roll it shows correctly, but if i look on the plane it is reversed. anyone seen this problem before or know how to fix.

on my futaba 8fgs i have it setup in model type as

type airplane

wing normal - 1 ail

tail normal

i have tried playing with the "elevon config" on the mission planner but it doesn't help fix the problem.

i have also tried swopping the channels which makes it correct on the plane but on the apm mission planner its wrong. meaning if i pull the joystick left and right (roll) it does that correctly on the plane but on mission planner it displays the pitch as going up or down when i do the left and right.

any ideas on how to fix ?

    by setting the ELEVON_OUTPUT to 4 under CONFIG/TUNING -> FULL PARAMTER LIST

    Hi Adam,

    Do you have an external compass module? If so check it is enabled and the Compass setting is "Rotation_Roll_180" as the compass is mounted upside down under the GPS receiver.

    If not check these kind of settings, go through the set up again, step by step!

    Best of luck,

    Keith,

      i have an internal compass in the apm 2.5
