I asked this question earlier in the Power Systems forum but did not get any replies.
The Hobbico Sky Fly RTF trainer has a combined ESC, BEC, receiver, and servos made from three daughter boards that are all mounted on one main PCB and held together as one assembly.
I broke one of the MOSFETs off of the daughter board that appears to be the just the ESC/BEC and repaired it by soldering it back in place.
You can see the ESC/BEC board and the broken off MOSFET in the first photo and the six pin header it attaches to on the board in the background. The repaired board is in the second photo.
The repaired ESC/BEC board works normally. And if I remove the ESC board from the main board with the receiver/servos, of course, the motor will not start. I suppose that makes sense since there is no receiver or throttle input. :>)
The six pins on the ESC/BEC board are labeled:
GND
3V
THR
5V
B+
BRAKE
I recently got a JR SX600 system with a RS6UL receiver and two SM22 micro servos and I wonder if I can use those with the Sky Fly's ESC/BEC board by connecting some or all of the six pins on the ESC /BEC board to the RS6UL receiver?
The RS6UL receiver has the standard seven three pin headers for BATT, AUX1, GEAR, RUDD, ELEV, AILE, and THRO. And each of those three pin headers has connections for (+), (-), and (S) or signal.
It seems like if I connected the 5V and GND to the (+) and (-) on the receiver's BATT header it would power up the receiver. But I don't know what, if anything, to connect to the (S) on the BATT header. Nor do I know what other connections would need to be made between the RS6UL and the other pins on the ESC/BEC board.
Does anyone know how I could connect the header pins on the ESC/BEC board to the RS6UL with some chance that they might work together?
I have a brushed motor ESC/BEC on order and will eventually replace all the Sky Fly electronics with the new ESC and the SX600 system. But thought I might experiment with the other stuff in the mean time. If I'm putting my new receiver at some risk by trying this I won't do it.
The Sky Fly has plenty of power so I don't feel a need to do a brushless conversion to it. But I would like to try it out with the SX600 radios and servos.
Thanks for any help or suggestions,
Jack
