Report Problems with RCAP in R/C Telemetry, FPV, RPV, and UAV Projects Posted October 10, 2004 I have assembled the RCAP and programmed the PIC 16F876A I/SP. When powering up the RCAP the diode stays off. Then, after ca. 10 seconds it is turned on. It will stay lit for ca. 40 seconds and then be turned off. Then a ticking sound can be heard from the servo. I can't control the servo from my radio at any time. It doesn't seem like I manage to turn the RCAP on or off. Does anyone have a clue what can be going on here?
