This is my first real quadrocopter with 4S.
Build it in 5 hours with no problems, now off to the tuning.
I already ordered a TBS Unify Pro Race, because the Eachine broke. Fortunately I had another one to hand. Additionally I need to add a capacitor for the VTX.
Will update my progress on tuning the PIDs.

--- Update 1 ---
TBS Unify Pro Race installed, flawless transmittion. Currently I get around 4.30 flight time with the Multistar LiPos with moderat flying. I might try some 5040 props soon.
For the tuning part I'm add it. Right now it's totaly flyable total response, but it definitely needs some tweaking in the turns. I ordered a runcam 3, so there might be some on-flight footage soon. Next step is to upgrade my cam to an arrow 3 or something.

All happy flying! :)

Interesting RX antenna placement. I normally run them from behind the front arms, so this is the first time I've seen them going forward from the rear arms.

The receiver fitted best in the back of the quad. But the antennas were too short to make them point backwards. Right now it works, I've got 4 spare antennas, when one might break, but let's see.
