Hi!
I'm comming from germany - sorry about my english. ;) This ist my first project with multicopters. I want to take some arial photos and fly fpv. I've build a X-frame for my octocopter (see photo). My frame with landlinglegs weights 880 gr.. Every arm (Alu 10x10x1) is 50,7cm long (measured from the middle of the centerplate):
I've bought the Ardupilot Mega 2560, the magnetometer and the OilpanShield Rev H. Then i orderd some Motors, ESC and Probs, but now i'm not sure, that this are the rights components:
- Motor: KEDA 20-22l
- ESC: HobbyKing SS 25-30 ESC
- Props: 8x 10x4,5 CF (4left/4right)
Is it the right configuration? Is it better to use 4s or 3s LiPos? Some users wrotes, that they use the keda 20-22l motors with 4s lipos, too. But then i need other ESCs? Or should i order other ESCs, Motors and Props (10-12x?) ?
The motor #11 must connected to the pin PE3(5) and motor #10 to pin PB5(11) on the ardupilot-board - see this at the picture. All Pins are now connected to the Oilpanshied. Must i cut the connection (from the to two pins) to the oilpan-shield, that the pins only connected to the two motors?
I want to have a relative long flighttime. The electric for fpv weights 189 gr and the separate 3s Lipo for fpv 160 gr..
Thanks for your help!

Arms too long for this motors/props! :-) You have to calculate so that the propellers have between them a space of at least 2 cm (blade to blade), and i think 40 cm is enough.
Don't cut anything in the OilPAN, just connect 2 wire for the motors.
Your esc is ok for the little Keda with 3s, also the prop 10x4.5.
Follow my example here, but is more heavy:
