Hey all,
After my first flight of N729PG, I have a tach issue to work out. It is erratic and fluctuates. I've confirmed everything is tight with good connections. I have the Dynon D120. The manual states to install the 30K ohm resistors which is how I made the first two flights. The manual also states that for my kind of problem that you may have to increase the resistance to as high as 150K ohm. Here's the question. I have put two resistors in series, one is 22K and the other one is 47K. The adds up to 69K ohms. I've confirmed this with my volt meter. Is this the correct way to "increase" the resistance or should I have used a single resistor with a higher resistance or does it matter. I haven't run with the new resistors yet. That will come tomorrow.
Thanks in advance
