One other thing i am still trying to work out, is my trim issue.

I have excessive right aileron trim and back elevator, which i've had to try and cancel out using subtrim! Seems to be working without a problem as i was not sure you could use subtrim on a quad, but i can't work out why i need so much trim!

The quad is balanced out correctly, nothing is bent, motors have the 5 degrees of pitch as per the build instructions, and i even when put them back to being straight just to see if it would change anything i still have this excessive trim.

Used to traditional rc heli's and i know if your c of g is off it causes trim issues, but like i say c of g is spot on.

 

Driving me a little crazy

Ok i finally figured out the excessive trim issue, it seems one of the ESC's had a different firmware loaded on it from the other three identical ESC's. So a change of all 4 ESC's was done and the excessive trim issue has gone away, along with the slight oscillations i was getting during flights.  Apparently it can be an issue were manufactures of ESC's can change their firmwares without notification or marking the fact.

hi guys ,

 I am very new , trying to figure out what to spend my money on ... my end goal would be to take my drone with me skiing and have it "follow me"  I have seen the very expensive Mikro copters do this , but I like the scarab frame and I am on a budget so not able to drop 20k into this :) .. Would I be able to have the following features by using a scab octo kit and using Ardupilot Mega Board in stead of the PARIS board ...   

Gps Hover( keep itself steady even in the wind)

GPS return to base ( in case one engine fails , battery low  or Signal is lost it should go up to a good alt , then head to start point , and slowly land by itself )

POV camera in addition to a GoPro V2 ,

goggles to see POV .. Ground station

And final feature I would like is "follow me "  I have a gps on my helmet , then camera follows me while I ski .

So are these things possible ?  I would love for it to be .. I already fly the Scarab stealth Armour with a paris board and no longer crash , so now I want to go a bit more advanced , but have no idea where to drop my $$ lol

Kevin: ArduCopter already has follow-me mode and the rest. $860 RTF.
