I had an IDEA to Build A gimbal using flight stabilizing gyro .....SO here is what I did

Items needes
1 2* 9g servos
2 thunjer p1 gyro
3 few plastic pieces for Camera mount

It was simple like every other gimbal build
It works perfect it stabilizes the Camera ...

What is did was I used gyro ON headlock mode
I used elev and aile outputs of gyro as 2 Axis for stabilizing
But ON the input side I Just connected aile input to receiver and a swithch wire ON channel 8 of receiver ....to put gyro ON headlock mode ... aile input is conmected ON channel 5 .....it was necessary because that wire powers the gyr

Rest of input signals of gyro are left alone
And two ouput used for gimbal


I works perfect

But here is the problem I am facing everytime I push or titl the gyro out of servos limit of responce to rotation ...when I move back to normal position I lose the Centre position of servo ....if I go out of limit Service centres in a different position ....
But till that extreme position is not somthing a quad CAN do if I angle my gyro more then 35-40 degree Om any of the 2  Axis I loss Centre position of Service

What should I do
CAN I use a different servo which won't lose its Centre posotion in any extreme please give some advice

Watch "My DIY gimbal with thunjer p1 gyro in headlock mod" on YouTube - My DIY gimbal with thunjer p1 gyro in headlock mod:




it looks little out of perfect mounting angle to put ON a quad right now ...but that's not the issue I will get it perfect .I works. It will stabilize my mobius

But how do,I get servo to Centre at the same position everytime
Is there any other type of Servo I could use???

Did you centre servos before installation? You could try other servos but a servo gimbal wont be as good as a brushless gimbal setup.
Build planes like feathers rather than tanks, both handle bullets equally well.

How to I Centre it before installation? ??

Yes I know it is not as GOOD as brushless one
But for now it will SOLVE my problem
