Hi,
Yes I have used the MFD system and achieved over 20 Km (46 KM round trip), with WP navigation. (could go further if not for battery limitations)
I have 4 different brands of AP's. 1 FeiYu Tech FY41AP (its an OK system, Negative points for no RSSI). 2. RVOSD (easily the best system that i have ever used except, the font size is too small (cant be changed) and the GUI is too cumbersome to use in flight) 3. ArduPlane AP2 (all round good system) 4. My Fly Dream V2. After using the other 3 systems I have found that the MFD is the best of the bunch because of its ease to use and set up. Its not as technically perfect as the RVOSD or the APM2 but for the price it cant be beat !
The setup that i used is as follows:
Airframe: Skywalker X8 and FPV Ranger
Battery: DUPU 10,000 mah for motor & 2500 mah for VTX and AP
Radio: Taranis plus with EZUHF external module and 8Ch diversity receiver (stock antennas)
VTX/RX: Lawmate 1.2 Ghz on 1080
Video Antenna: You guys wont believe this "Cheap HK LHCP" long stem antennas $15 for the pair. I got better video clarity with these than with the VAS bluebeam on VTX and VAS pepper box on the receiver (Ibcrazy $150+ for the set + shipping).
Camera: Sony PZO420
Auto pilot: MFD.
RF Noise: All the wires were individually wrapped in aluminium foil.
This was my normal setup for flying every weekend in Dubai till some IDIOT flew over the airport and shut down air traffic for over 2 hours. Thats when the Laws changed for long range FPV flights in Dubai.
Please understand that having ANY auto pilot will not guarantee a safe flight. There are a million things that can go horribly wrong and some are the most simple that are over looked. Please also AVOID the urge to use RTH in cases of video loss (RF loss will automatically kick in RTH is you set it up as a failsafe). Your AP dose not know the topography of the terrain you are flying over (Hills, buildings, etc), set goals in 1 to 2 km increments to test your set up. Your system will be under more stress the further out you fly.
1 point that i will like to mention thats very important is, PLEASE make sure that the battery for the MFD AP is ROCK SOLID. If you run out of juice or have a loose connection, you WILL NOT have any RC link. The stock OSD will only show you the Main Battery voltage and not the VTX/AP battery voltage (this can be modified, check

Fly safe .... and don't break the law.
