I'll go first.... This is a work in progress still.
First the spec:
FC- Hoverfly Pro and GPS boards
Frame- X468 medium with 1/2 square wood booms and balsa 'faring'.
Motors- Sunnysky 2216-11 800kv short shaft.
ESC- Hobby King blue 20A.
Props- APC 10x3.8sf top APC 11x5.5e bottom.
Batteries- 2x5000mAh 3s.
Rx- Spectrum AR8000 and satellite.
Gimbal- x468 medium and EMax ?08MD servos.
VTx- Fat Shark 5.8ghz 100mW (foxtech one pictured has since been binned).
Camera- Cannon EOS550D
TX- Spectrum DX8.
Ground Station- Airwave 5.8ghz VRx, 7" Monitor, DVR and 3s battery voltage monitor display.
Why Hoverfly?
There are more developed systems with more features and debatably better performance for not much more cost available, but I'm looking for something beyond that, service and support. That's where I think HF win over every other system. There is a dedicated HF forum that is regularly supported by the HF team. ALL systems have their problems and set backs but it's how those problems are dealt with that counts in my book. With HF I have an English speaking person who I can deal with directly.
It has some unique features that not even WK-M has like a high quality OSD backed right into the FC.
Frame?
I have chosen the x468 frame because of the options of configuration including hex in + that HF supports (hex x is coming soon because of demand). I've made my choice of Y6 but like the option to change if necessary. Y6 gives me true redundancy and good wind authority from experience. I've also chosen wood booms, this may appear a strange choice but has solid reasoning behind it. Rather than trying to 'fix' vibration and camera jelo I'm trying to build a rig without vibration. Will balanced props and motors first, then wood booms to absorb and dampen and vibration that's left. Metal and even aluminium will transfer vibes straight down their length, the wood has some nice damping qualities to it naturally. I also am taking prop wash hitting the booms into account. Square is easy to keep motor alignment but the large flat surface gets hit by the propwash and causes its own vibration, round is better aerodynamically therefore better in this situation. My answer is to fit a faring to the top of the square boom improving the propwash aerodynamics, hiding the motor wires, retaining the strength and keeping motor alignment. Also in the frame I'm using the 'gaps' left by the Y6 design to make antenna booms in order to keep separation between antennas and sources of interference.
Powertrain?
Not much needs explaining really. The Sunnysky motors are very good quality for the price and are just rebranded T-motors. I'm staying 3s as that's what I already have plenty of. The esc's are cheapo but have good feedback on the forums and have more adjustment than the likes of Turnigys. Being able to run them at 16khz should mean I don't get that 8khz wine that annoys me to death. Props may seem strange to have different top and bottom. I'll go into that later but it's all about increasing the efficiency of the coax setup.
Camera.
I've gone for the 550D after lots and lots of research. It's gonna be a tight fit in the gimbal but I was leaning towards the NEX-5N at the time. The 550D allows live video out, no proprietary files to convert and most importantly the mrs wanted a proper SLR so she can also use it when I'm not. I've made sure the three year insurance covers accidental droppage ;-)
Ground station.
The DX8 is plenty enough for control and I've had no issues with it. I also have a video downlink that is displayed on a 7" screen with the OSD for flight info like battery voltage, gps coordinates and the like. I won't be flying FPV with this setup (I have other quads and planes for that) it's just for framing shots and flight info.
Some photos (these are all early mock ups and some items have already be superseded by better)
