EPP FPV plane from HK

Hi Guys

I’ve had this project on the backburner for a long time and now I've found the ideal platform. I chose the EPP FPV plane from HK. This aircraft when completed will be ocean water tight AV/AP platform with video down link on and off ship operation.

Lake Day (6 min 48 sec)







Design challenges:
-Water tight main fuselage that this platform does support with additional fabricated water tight hatches to be constructed out of fibreglass.
- Remote mounted rudder and elevator servo to be relocated to water tight fuselage.
-Removable flight surfaces that break down into their individual components; L&R wing, vertical and horizontal stab. (Modification is required here)
-Stabilized flight control system with AHR and GPS return home function.
-Water tight Camera system that records HD 1080 60fps; Go-pro hero with a small mod to enable water proof connection AV out.
-Water recovery system; D ring or loop mounted at C of G point, and fibreglass pole with hook for water retrievals.

Control system main processor component; KK Board

Wiring lay out and SW versions to be determined but had planned on using the Wii motion & nun-chuck sensors at this time for the main AHR components.

Any suggestion or advice of SW at this point would be appreciated.

Thanks Jerry

Standard Aeroplane OpenAero KK control HK EPP FPV test flight was successful. Wind was low sky’s were foggy, the OpenAero sw performed excellent, we perform two test fwd and aft C of G operation.

Here's the latest aerial video test flight going well. The roll rate was a little high and my camera mount had a little play so the video was less than perfect but quality was good and based on the condition at this time I'm very happy. Unfortunately viewing from the ground she looked great. I've shimmed the camera mount, reduced the roll gyro rate and re-jigged the elevator control to add more throw.

Final got this thing back in the air, work still in process. I tried some landing gears on her, water and wheels.

I still plan to move fwd with this project. I just got a little stalled. I'm still working the standard control system but I've notice this plane had large torque roll issue. I've off set the motor still having some yaw issue though.If any of you EPP FPV guys have any other sugestion?

Thanks Jerry

Hi Jerry

Regarding your mwcontrol, there are some interesting developments over on the mw forum. You might be interested in this thread http://www.multiwii.com/forum/viewtopic.php?f=8&t=364
Not tried it myself yet

Hope this helps ...

/Frank
