Big Flapper Posted November 21, 2020 Report Share Posted November 21, 2020 On my "New" CTLS while on the ground when I put the flap setting to -6 I hear the flap motor running and then stop but the numbers still blink and the red light on the upper right of the display is on. This also happens on the 35 deg setting. Looking at the maintenance manual this looks like a control rod out of adjustment to me. Just want to confirm this before I dig into the airplane and make some adjustments. Quote Link to comment Share on other sites More sharing options...
Roger Lee Posted November 21, 2020 Report Share Posted November 21, 2020 It can do that if you are at low rpms with low voltage with all your electronics on. Rev the engine up to 3000 rpm and see if it still does it. Quote Link to comment Share on other sites More sharing options...
Big Flapper Posted November 22, 2020 Author Report Share Posted November 22, 2020 No other electronics on except Dynon 120, had a battery minder attached to the battery. Quote Link to comment Share on other sites More sharing options...
Roger Lee Posted November 22, 2020 Report Share Posted November 22, 2020 What was the voltage and try and run 2-3 cycles and see if it's just a first start running a bit cold issue. Quote Link to comment Share on other sites More sharing options...
Big Flapper Posted November 22, 2020 Author Report Share Posted November 22, 2020 Did 6 cycles all settings except -6 and 35 worked fine, numbers stopped flashing when flaps reached the assigned angle. on -6 the upper red light is on and the number continues to flash even though the flap motor has stopped. Same for the 35 setting except that the lower red light is on. Voltage is 12.9 Seems like the limit switches are stopping the flap motor before it reached the flap setting.

Roger Lee Posted November 23, 2020 Report Share Posted November 23, 2020 You may just need to do a re-program for the positions and circuit board. I'm a tad surprised your voltage isn't in the 13's. Quote Link to comment Share on other sites More sharing options...
Big Flapper Posted November 23, 2020 Author Report Share Posted November 23, 2020 Where can I purchase the switches for the reprogram? Quote Link to comment Share on other sites More sharing options...
Roger Lee Posted November 24, 2020 Report Share Posted November 24, 2020 These are very simple switches. Call FD. Quote Link to comment Share on other sites More sharing options...
CTSW Bob Posted November 25, 2020 Report Share Posted November 25, 2020 Try reprogramming before you do anything. One failed start or low battery dip seems to throw my flap computer out of whack. Solved by replacing the battery and I keep it on a trickle charger. I have a thread on here about reprogramming. I hope it fixes it.
