"In my experience, APM flies better without SimonK. More accurately: non-autopilot modes are fine (great, even) with SimonK, but any autopilot mode (including loiter) is better without. This includes RTL, so beware.
Also: SimonK ESC's do not need to…"
"Not true. And I already know that no evidence will ever convince you, you're just going to have to experience one yourself and then you will understand. In the meantime, search youtube for "naza flyaway" and watch the evidence. Naza's can flyaway…"
"I was referring to your last picture, last section entitled "Mixer settings." Your picture shows you set up CH5 to switch depending on flight mode. Each of those weights is added to any other that happens to be active. It looks like it works in this…"
"In my experience, this is compass. I've learned that loiter on APM can be stable even with a bad compass, so I always rotate my model 180 degrees and watch it loiter again. Then I set off on my flight.
At all times, I have my hand on the switch that…"
"Replying to my own post (shame shame) but it looks like both the X8R and the X6R will do both SBUS and PWM on one receiver. Hard to tell for sure from the documentation, it might take some experimentation."
"We've all been there!
So I'll make these suggestions. You can pick the one that seems to fit best and I'll help as best as I can.
1) Use 2 X8R's. This will give you SBUS on one radio, and PWM on the other. You keep telemetry, but now you'll have 2…"
"Gotcha. I've looked into doing something similar. You have a couple options, but you will need an XJT module. Is that what you are running? Most of us Frsky users run a DJT module on our 9XR's.
Do you only need one output? I can tell you some tricks…"
"They're just trying to sell you a radio.
Tell your hobby shop pals that I flew my FrSky-equipped-quad out 2 miles yesterday (a personal best). This was on stock equipment, no special antennas or boosters. I had telemetry telling me my battery and…"
"In the states? Use "Swiss Post" for HobbyKing orders shipping from their China warehouse. Shipping is quite reasonable and I usually get my parts in 6 days (!) Use their US warehouse for as many parts as you can, and use USPS priority."
"OK, I tried lowering THR_ACCEL_P to 0.25 and THR_ACCEL_I to 0.5. It did smooth out the altitude oscillations in loiter, but it seemed to exacerbate the violent over-correction I wrote about in the other thread. I have nearly identical F450's with…"
