Tricopter APM2.6 FPV AP/AF

Hello,
to assure that I am not doing any big mistakes or forgetting anything I would like to share my planned components and the way I am planning to combine those. Thanks a lot for your feedback in advance.

This is my plan for building a Tricopter designed for filming and photography with the possibility to locate filming-/phototargets via fpv.

1. Flight controller: APM 2.6 with LEA6H GPS

2. Flight controller power supply: HKPilot Power Module

3. Tail Servo: TGY-306G-HV

4. Motors: Tiger MN3110-26

5. Propeller: Turnigy 14x4.5 (2x CCW 1x CW)

6. Motor ESC: BULL TEC 35A 4S SimonK N-FET

7. Remote control: Walkera F7DS
http://www.rcmaster.net/de-walkera-devo-f7ds-fpv-sender-2-4g-bild%C3%BCbertragung-kit-version-p235720.htm

8. Receiver: Walkera RX701
http://www.rcmaster.net/de-walkera-devo-f7ds-fpv-sender-2-4g-bild%C3%BCbertragung-kit-version-p235720.htm

9. Receiver power supply: 5V UBEC

10. Videotransmitter: Walkera TX24D-01
http://www.rcmaster.net/de-walkera-2-4g-bild%C3%BCbertragung-sender-tx24d-01-p235824.htm

11. Battery: 4S 6000mah 25C
http://www.hobbyking.com/hobbyking/store/__32643__Turnigy_nano_tech_6000mah_4S_25_50C_Lipo_Pack_EU_warehouse_.html

12. Gimbal: Tarot T2D
http://hobbyking.com/hobbyking/store/__44327__Tarot_T_2D_GoPRO_3_Brushless_Camera_Gimbal_and_ZYX22_Controller.html

13. Gimbal power supply: 12V UBEC

Apart from this there are other components, as Lipo adapters and breakout-cable, cloverleaf antennas, go pro camera, Low-voltage beeper, low signal beeper, etc.
The AUW will be approx. 2.1kg

Questions that have already come up are:
1. Can I connect the ESCs and the UBECs all to the same Lipo by just soldering them to bullets or however connect them to the lipo-breakout-cable?
2. What type of powersupply would I need for the Video TX? Can I connect it to an existing(planned) UBEC?
3. Does the Tail-Servo work by just attaching it to the APM2.6 board?
4. Are there any parts that could be improved/better solutions?
5. Any good onlineshops in Europe/Germany to get these parts?
6. Have I made any big mistakes?

Thank you very much for you attention and feedback in advance!

best regards

Hi Colya, welcome to the Forum!

I can't really help you with the tricopter layout or the esc, motors, props as i am also pretty new to the multicopter world.

I can only answer some of your questions.

Yes you can power all the equipment from one lipo. But be sure to solder a parallel circuit (for example a simple Y connection to connect two devices to one battery http://en.wikipedia.org/wiki/Parallel_circuit) so the voltage stays the same on each device but the current will be divided on each power strain. But keep in mind, the more equipment you power from your "flight lipo" the shorter your flight time will be.

I have no experience with your listed Transmitter, but they are usually eiter 12v or 5v powered. So with a 99% chance you can power them from one of your planned UBEC's.

Hope i could help you in some way...

thank you very much! Already received some parts... changed a bit from this list. will update soon
