But Problem is
Having Issue with FUTABA 8FGS with this Kit. Using Mission Planner and step by step wizard I am Able to complete all the steps for configuration except one viz. Not able to arm the APM . I have try the reversing the throttle channel also but no result even not able to calibrate the ESCs. In wizard the the channel/sticks calibration was successful but not able to arm the APM. Please Help me Thanking you in advance

Dear rcluman,

You must hold the rudder stick to the extreme right for more tha 5 secs, then only all the motor should start at a very low speed.
Try the radio calibration not by wizard but the normal initial setup process and check all the directions are correct.

Are you doing calibration of all esc at one go or separate.

I have done all ESC calibration in one go.
I was able to arm the Board but throttle was not working rudder elevator and aileron channel was working as it should be  but
though you apply full throttle but motors were sipping at very low RPM.

Disconnect one esc+motor from apm connect directly to rx throttle channel and calibrate  by tx method.

this works .....just give a try for all esc's same way .then connect to apm.

Thanks arun21 let me try your suggestion. Another Question is that I am not able to arm it few months back I was able to arm but the throttle was not working, But Right now i forgotten what was the solution to arm the board I only remember I have tried something with END points
