The plane was very well packaged, and only had a few minor foam dings from packaging that was expected from a model this large. From removing it from the box to a finished product took just under an hour. My initial thought was ''WOW'' This plane was very large for an EPO Foam bird. I purchased this plane with the intentions of having a smaller practice plane to take to the field when I am time crunched to take my regular 2meter. Well thanks in advance for any info, I will be sure to post updates as I go.I purchased an FMS F3A Olympus at the Toledo show. I saw on another similar post, on pg 1 say something abut using settings to configure the motors as opposed to the output pg. And if I connect it to the gcs, I link all the motors, move the slider side to side, and all the motors respond perfectly. The problem never followed a component, nor occurs with any pattern, it is completely random. I swapped around escs, I swapped around the motor inputs on the revo board just to see, then I changed out my revo board for another.

Some motors will come on, some wont, the ones that came on went straight to full with a mm of throttle, the others might come on at about half throttle. I set everything up correctly, ran the wizard as I did in a previous build, everything went as planned, the motors tested as they should, using the gcs, the motors increased/decreased, and all worked together.

My build, a 550 hex frame, 1500kva emax motors, 30amp simonk esc w/bec, frsky x4r receiver in sbus config and taranis 9d plus radio, revo board with updated firmware. Hey all, so I am having a similar pblm with my motors misbehaving. I finally got the vibration manageable by running a string around from gear to gear with a couple loops at each one so that each string was tight. I noticed that the vibration only happened at one frequency, and that a small amount of holding it with my hand would stop it.Įach arm has a small landing gear extension at the bottom. I static balanced the props, then used a "servo tester" connected to one motor at a time and dynamically balanced each prop by finding the best place to put a piece of black electrical tape to minimize vibration (as felt) (measured would be more accurate). I spent a long time fighting vibrations on a cheap plastic quad. You must get your props balanced well to be able to fly it. I would suggest Pos3 = Stab1 + Bank3 just because Stab1 is the easiest to fly if it does something strange. Fixing your vibrations and reducing the D terms is what will fix this problems, but there is no way to tune it if there is too much vibration. Balance and track those props!ĭo you get a lot of power with very little throttle stick and yet don't get much more power when you give full throttle stick? If so, then you definitely have these invisible oscillations. Vibration from motor/shaft/adapter/prop being out of balance or out of alignment makes this a lot worse. If you do the FMS toggle with it armed, it rotates through a set of 5 SmoothQuick settings (read the AT wiki page).

Reexport happens whenever you move the SmoothQuick knob, or if you haven't set that up, while disarmed, just toggle the FMS quickly into and out of AutoTune mode, like 1,2,1,2,1,2,1 if position 2 is AutoTune. DerivativeFactor (0.0 to 1.0 are reasonable values) default value is 1.0 Try setting it to 0.5 and "reexport PIDs". If you are using AutoTune there is a setting that reduces D and slightly reduces PI. When you do that, you need to reduce the PI gains a bit too to avoid oscillation. The solution is to reduce the D gains in whichever PIDs are responsible.

Our firmware sees that the throttle is very low, and to give full roll it must increase the throttle to 50% so that one motor can be 100% and the other one 0%, then it switches from 100, 0 to 0, 100 and back and forth, the result is that all motors are running about 50%. The quad sees it though and the effect is that it gives full left roll then full right roll (and pitch) many times a second. There is an issue that I call "invisible oscillation" where the oscillation is so quick and small that you don't see it. I bet that your quad is fairly powerful and hovers at much less than half throttle.
