"A bad pitot tube can be the problem!
The tube end is not glued and therefore the pressure to the sensor is not constant, ie. it leaks. You should be able to test this if looking at the numbers in MP and put constant pressure on the end of the tube.…"

Skywalker 1900 Parameters
Started this discussion. Last reply by Hein du Plessis Jan 6. 1 Reply 0 Likes
Hi folks, I had to buy a skywalker 1900 after I stuffed my original 1500 into some trees. Does anyone have a good, solid param file for their 1900 that wouldn't mind sharing? This would be…Continue

Tuning: Throttle Oscillating during Loiter
Started this discussion. Last reply by Calle Apr 10. 8 Replies 0 Likes
Hi everyone!During Loiter, my throttle oscillates rather consistantly. The tuning graph suggests that APM is responding to airspeed (as opposed to altitude) because of the frequency of the…Continue
FBW_A and Stabilize don't agree on Level [solved]

Hi folks,On the bench: When FBW_A is enabled, all control surfaces level off when I tip the plane 20 degrees up and roll it about 30 degrees right. When stabilize is enabled, all surfaces are level…Continue

spagoziak replied to Guustaaf Damave's discussion Fly at fixed distance from walking person"Chris,
Will Follow Me be made available for arduplane as well? I suspect the only difference in behavior would be that the plane would loiter on the target if the target's speed were less than some amount.
Putting APM on a fast…"

Did you get this issue resolved? What was causing this?"
spagoziak replied to Rick Eis's discussion FPV Video using APM2 ?"I'm flying FPV with APM2, but I wouldn't say the videos are nice lol....
I just have the pilot camera feed recorded on my laptop. Not enough $ for an HD camera!"
spagoziak replied to spagoziak's discussion Tuning: Throttle Oscillating during Loiter"I'd think off center would be just fine, so long as the tube is parallel with the forward direction of the plane. And keep those static holes at least an inch away from surfaces."
Tim McPherson replied to spagoziak's discussion Tuning: Throttle Oscillating during Loiter"Thanks spag,
I appreciate the installation information. I have to install it on my X8 and would like to have it somewhat protected from damage during landings. A camera bay on this model pretty much excludes the upper front center for mounting the…"
spagoziak replied to spagoziak's discussion Tuning: Throttle Oscillating during Loiter"Hi Tim,
My pitot tube is protruding from the nose of my skywalker about 2". I melted a track in the top of the foam for the tube and the foam canopy holds it in place snugly while still letting it sneak inside if I land poorly.

Tim McPherson replied to spagoziak's discussion Tuning: Throttle Oscillating during Loiter"Hi,
If I may ask, what does the airspeed sensor installation look like? Is the pitot tube installed in an undisturbed airstream?
I'm just curious because I need to install the one I've recently received from the store here. Thanks.
Tim"
spagoziak replied to spagoziak's discussion Tuning: Throttle Oscillating during Loiter"I know this one's a puzzler, but doesn't anyone else have this in operation on their plane?"
spagoziak posted a discussionTuning: Throttle Oscillating during Loiter
Hi everyone!During Loiter, my throttle oscillates rather consistantly. The tuning graph suggests that APM is responding to airspeed (as opposed to altitude) because of the frequency of the oscillations and how it relates to my target alt.If there were a PID for airspeed alone, I'd probably be able to make sense of it.. .maybe lower P and increase D a bit. However, i don't see such a loop for that particular aspect, so I'm a bit lost. What would be the best way to smooth out throttle…See More
