Looking for some advice,concerning quadcopter

Postby Salem » 28 May 2015 09:40

Hello everyone,I am new to this hobby in terms of attempting to build my first quad,but long story short ,I got a nanowii fc kiss esc 18 and I was going to use a bec to power up fc since kiss esc don't have them run off of power distrabution board but what I wasn't sure of is since grounding esc to power board ,do I also ground them to fc for each individual signal coming off of esc?or is it just signal wire no ground to fc ? Hope you know what I mean.

POWER : Lipo + and GND to KISS and BEC.

BEC (5V) und Masse an FC.

Signal and ground of KISS to FC.

Hello pic18f, thanks for the response ,I am pretty sure I know what you are saying,more less I will ground all esc to FCC with signal wire,besides grounding esc to pdb

The signal for KISS modulated PWM.
Noise change the pulse width and thus cause incorrect setting values in the KISS. :cry:

The common connection of GND, reduces the susceptibility of the control signals to the ESC. :mrgreen:
When using aircraft and receiver battery the GND connection is actually duty.

What weighs your Copter maximum?

motors x2208 2000kv >>>http://flyduino.net/Multikopter-Brushless-Motor-Multicopter_31
Look at please below the table regarding propeller, thrust and power consumption (100%).

At 50% control value approximately 1/4 of the copter should be weight.
He has more than enough reserves in emergency situations.
(e.g. to intercept during free fall or fast start)

Maximum current consumption:

4*( Imax motore) + (Imax accessories) = Isum A
Isum * 1,25 = Isafty A

Iakku * ??C *0,75 = Ilipomax A


Isafty A < Ilipomax A
The greater the difference, of the so longer shall your copter flies.

My Copter weighs 1200g with all accessories and flies about 30 minutes.

Lipo 2x 3S 5000 30C
frame CFK
Robbe Motore 2827-34
ESC 20A ESC Simonk
FPV goggles "Fat Shark" not HD
FPV Camera with SD Card "FLYCAMONE ECO HD"
FPV camera stabilization "Horizon 3 servos"
Remote Control Transmitter Spectrum DX5e
Remote Control Receiver Spectrum sattelite direckt connected to FC
FC Nanowii or Crius AIOP V2.0 PRO

Yes.
+1 To +2 and -1 to -2 (parallel).
The balancer terminals are connected NOT parallel (separated!).
1. Both lipos fully recharge!
2. both + pole and both - pole parallel connected.

!! WARNING !!

Event of polarity reversal or short circuits may cause a fire or explosion hazard !!!



Both Lipos need an undervoltage protection. >>> http://flyduino.net/1S-8S-Dual-Speaker-Lipo-Alarm-8S-Voltage-Tester-Lipo-Checker
