Did you by chance also incorporate the anti-vibe kit and relocate your IMU as per the kit instructions?

RTH tested again tonight after recalibrating the compass but it still did not work properly. After turning around and heading over the takeoff position it continued to climb........Had to override RTH to get it home safely.

Extremely good information here from all and greatly appreciated. In addition to competing with conventional solutions such as manned helicopter c/w pilot cameraman and maintenance ground support I have learned here that the Multirotor can get in much closer and do work that is not possible any...

Thanks for that posting and video Olof..... which firmware version are you using now? Did you have any issues with barometric pressure sensor of controller program/fw causing sudden motor surging or drops in rough air?

Smooth and excellent work..... BTW.. Can you change the gimbal pitch angle remotely from RC xmitter?

Nathasm also asked about volt protection settings in his original question but everyone so far responded only on the gain settings. I believe the volt listing he wrote were the defaults that WKM Assistant loads...... not the best choice for real world flying..... Anyone care to share there new...

Good point......still it remains possible to freeze the prop adapter/nut assembly with any nut cranked on too tight.

Caution: The prop nuts can easily seize or freeze to the softer aluminum machined prop adapters if you tighten the nuts too hard or use the wrong type of Loctite. Once frozen.... you have to cut them off to get the props off. But they are cheap so buy spares. I prefer to buy motors that offer...

I have owned the LK900 and GCS since January and have tried multiple times to understand how to operate GCS in simulation mode...... But because I find it so confusing, I refuse to test it in real flight........I will try to figure this out later.......as for now I am flying without it. It...

The fact that the S800 remained level with the horizon suggests that the controller was not rebooting as the gyros etc. are still giving it orientation control. It is common in the spring, summer, fall for thermals aka updrafts to occur. Once your MR gets to the top of a thermal it can suddenly...

Since the WooKong have the additional gimbal control feature built-in, the need for an ancillary camera gimbal/imu would be technically redundant. So it would seem that a more optimum placement of the single IMU would solve both the MR control as well as camera stabilization. IMHO - any MR...

SMP - Excellent information here.

Excellent feedback obtained from several already. To be more specific, the nature of the work I propose to do will begin with Video test shoots followed eventually by professional video shooting. So it will likely be a loss leader until I get all my ducks lined up and I am still at the "proof...

Good advice from TomBrown1...... Blade MQX BNF vc/w cheap entry level 4 channel fhss 2.4Ghz RC radio or buy the Quad only and buy a really good RC radio to go with it..... i.e., 8 to 14 channel Spectrum or Futaba 2.4 Ghz...... not a parkflyer RC system if you plan one day to fly expensive...

Make sure the motor mounting holes will work with the F550 arms or you may have to modify them. The 924 has a recommended prop diameter of 11 inches which should fit on the F550 without props hitting each other. And it seems to me that 22 poles @ 924kv will give you the torque you require for a...

Pete...... Excellent design..... Fiberglass or carbon fiber reinforced wood is a very smart way to go..... I make my own with a vacuum bagging system that I built so that I don't have to use a 2 ton press. Here is where I got the idea. http://www.dragonplate.com/ecart/categories.asp?cID=58 It's...

Why not just read the manual for the F550?.... the diagrams show exactly what you need to do.....

IMHO - I think the 65C rated batteries are overkill...... and will only gain you a minute or two over a 35C rated battery....... at least according to my repetitive ecalc calculations comparing the two. Don't buy GCS - Ground station for at least a year IMHO. GCS is ideal for flying 10...

Quality battery chargers will always come without a 12VDC input source. There are many surplus network server power supplies kicking around that are dirt cheap and provide very high quality DC power for your charger. I picked up two of these for only $50 plus shipping from a US surplus...

That is an excellent question.. Seems to me, based on some previous posts on this forum, that Manual mode only sees the gyro inputs..... So with respect to trimming in manual mode, there is not much opportunity to trim anything. But we need more insightful responses from others.
