I am looking for turn key setup info for my new F550 build. I am useing the Naza M V2 and Futaba T10J. I have found several sites with info that I have tried but don't trust launching my F550 on it's own. Currently I have been testing in backyard while holding onto the landing gear. Startup seems normal and have done compass cal and have gps lock. When I move throttle just past center like on take off, it pulls up and I release my grip slightly to let it settle into a hover but it then goes full throttle wanting to climb. I am tempted to teather it to a 10 ft cable for testing so it wont just accellerate into the stratosphear while I attemt to calibrate trims. It will back down if I move the throttle down. This is my first kit build so I am cautious about letting it go free. I have a DJI P2V+ and a P3P so I have a lot of flight time in with those. Any help with a step by step setup with the setup I have that I can be confident in useing. I need precise Naza settings including gains and Futaba T10J settings as well.
Thanks in advance.

Just to add, My F550 is bare with no add ons and I am useing a 6000MAh 4 cell LiPo (mounted on top plate). Craft has also been balanced to center. E300 Propulsion

It sounds like you need to set your throttle end points in your Futaba radio. It should not do what you are describing. Sorry but I am not familiar with Futaba. You could try to do a google search of Futaba setups with Naza.

So since I have had no real world advice from someone who has done an exact build (with my current radio setup) and reviewing lots of vids none of which has helped me I am going to sell off this rig. Despite everything I have tried and no real useful input here to my exact setup. I am not confident to release this bird to untethered flight as it continues to have a mind of its own. So for now I will stick to my DJI P3P which performs flawlessly. Thanks to those who tried to give help.

I hope you were able to sell for a good price and hope you are enjoying your P3P.
