I'd stay away from any of the Mastor gimbals, no one is having any luck with them. Read some of the users issues here and also the lack of response from the manufacturer as the thread progresses... http://www.rcgroups.com/forums/showthread.php?t=1892474 Ken

With the 2.0 version of the Alexmos firmware you can set the PWM to "high" to eliminate the high pitched squeal from the motors, it basically increases the frequency from 8kHz to 16K, beyond what most of us can hear... Ken

Depends on which of my multis I'm flying, most of my APV craft have rarely if ever crashed, my aerobatic practice quad often crashes 2 or 3 times per battery, my FPV quads only if something breaks or I try flying through where I probably shouldn't. In my case at least a large majority of the...

Flying FPV my QAV500 with Avroto 2814 motors on 10 inch props and 4S can easily sustain 50 mph in FF, I've seen as much as 54 mph on the OSD display though it was getting a bit unstable at that speed. Realistically you probably won't get much beyond 60 mph for any sustained forward flight with a...

That's a right hand circular polarized clover leaf antenna, hands down the best type of antenna for use on a multi. You'll get 3 to 4 times the range from this style antenna than you will from the little rubber ducky that ships with the vTX. You will also want to have a circular polarized skew...

The problem you're going to have on the F330 frame is finding enough real estate to place all the components so there's no interference between them. I built one using a Naza with GPS and it took a bit of creativity to get enough separation between the GPS and video TX so that the GPS would get...

Thats the NEHC club field in Mansfield MA, one of the few large treeless areas around here that doesn't have a shopping mall or houses in it! It is a Flip quad frame, probably the most durable frame I've ever owned. I find it perfect for practicing aerobatic flying since I've tried my best to...

Boris, it is all 6 positions, I looked up the manufacturers recommended calibration procedure because I couldn't quite figure out what the manual meant by the other 5 faces. If you don't have a perfectly square surface plate or instrumentation to precisely measure position in all orientations...

Correct, with the WKM you have three modes, fully manual, ATTI and GPS. ATTI mode is autoleveling with altitude hold, it's both or not at all (manual), when you turn on GPS you get ATTI plus GPS position hold, again all or nothing. With MK autolevel is always on but you can tune it to be as...

Like any other gimbal the brushless systems require a good initial setup and then fine tuning to get it perfect, the difference is they actually work once you get it dialed in. Some aspects of the setup like camera balance are MORE critical on a brushless than on a servo driven and then there's...

The easy way to think of it is as though you have a small square cardboard box in front of you. What you want to do is place the sensor board perfectly level on each "face" of the box and then hit calibrate. Start from either the top or bottom depending on where your sensor board is mounted on...

Not sure if you're aware of this or not, the Martinez GUI only works with the lower single digit comm port numbers so if you're connecting the board and it shows up as 9 or higher you should go into system management and change it to a lower number, I set mine to 2 and then it worked. That said...

Having owned PS1 multirotor gimbals in the past I have never seen anything approaching professional quality results in my own use and anyone else's for that matter. I wouldn't be surprised if the PS1 brushless gimbal delivers less than optimal results at best. I've watched what they apparently...

That is strictly for doing panoramas when attached to a stationary tripod or other suitable support, not at all what you would want on a multirotor or any other flying platform for that matter. Ken

What happens when you give it the TX command to arm the board? Ken

It sure is, now if I could just find some props that would hold up that well! ;)

I see from the website the Halo gimbals are available to order. The GoPro Halo 1000 version lists for almost as much as a DJI Z15 does in US dollars, $3342 at current exchange rates! Right now I have an RCTimer brushless gimbal ($99) with an Alexmos controller ($170 with sensor board) for a...

Well, I don't know about anyone else but as for the here and now I'm quite happy with the setups I currently have ready to fly. I can carry the Nex 5 on the CS with BL gimbal and I have a pair of GoPro size setup, one to carry the Hero 3 and the other to carry any of the previous versions which...

As much as I was an early adopter not only of the PH gimbals but also beta tested the RSGS and then bought a production unit, I don't ever see myself buying any of their products again, it's simply been far too time consuming and aggravating trying to get reasonably good results from any of it...

Adding a new dimension to my FPV experience, this is from the first test flights of my fully aerobatic FPV quad. I haven't had an adrenalin rush like this from FPV since I started flying through the goggles several years ago... Right now I'm limiting it to using a monitor and LOS testing...
