Mk has always had RTH via TX switch but now it's configurable in the firmware to do it automatically after loss of signal, a response to the WKM being able to do it I guess. The ground in the picture isn't where it landed, that's just the road where I parked the car, the quad actually landed on...

The little F450 flew well and the video gear worked pretty good as well. I do need to do some more work with the antenna setup as it seems to get blocked by the bulk of the frame in some orientations but the ground station doing the recording seems to be more affected than the video in the...

I'll find out tomorrow, I'll be in an open field with a good half mile or more of LOS to fly in. I also have some right angle adaptors and shorter antennas to try if I find this setup doesn't work as well as I'd like. Not looking for a lot of range on this one, I'd be happy to get a few hundred...

As part of my recent MK FPV quad project I've been upgrading all my video gear and with the newfound freedom of video goggles with built in RX I decided to put together a grab and go FPV rig that requires minimal gear to get in the air. What I did was soft mount both an SN 777 camera with an...

The two servos connect to the Naza controller and will automagically keep the tilt and roll axis steady and level, sorry no pan capability, for that you need a three axis gimbal and a second TX/RX. The good news is being a multirotor you easily yaw with the rudder stick to pan, so not a big deal...

Quick update, the other day I took it out back after the rain stopped, powered up, took off and within a minute it leaned to the right rear and did a lazy drop to the dirt! Broke one of the 9 inch Graupners but that was it, swapped the props for the set of 8 inch and went back out later in the...

The big difference is cost of replacment parts, a new ESC for my Cinestar is $15 or less and I don't have to buy it from a single source, i.e. DJI. Same for most of the other parts on it, with the S800 you have to buy from DJI and that severely limits the availability and how quickly a...

That would explain why I haven't gotten any in a while... Fixed! Ken

The RX is a R921X DSMX and will not work with DSM2 satellites, from the R921X users guide... DSMX receivers are not compatible with DSM2 remote receivers and DSM2 receivers are not compatible with DSMX remote receivers. Ken

The lens swap isn't hard, just take your time doing the disassembly and layout the screws in a way that you know which ones go where when it goes back together. A few things to be aware of, the stock lens is locktited or glued in so the focus doesn't change, wrap a piece of electrical tape...

DSMX is the problem, the older DSM2 stuff will work fine but you can't mix and match successfully. My JR 11X which is DSM2 gives me a full 11 channels on my MKs through standard Spektrum satellites although I did bind the satellites to the TX through an 11 channel RX first. I have a JR 921 DSMX...

Wait till you have fun like this, first instance WKM Y6 with Photohigher AV130 underneath before the WKM had the motor arming feature. I had a throttle hold switch setup to keep from accidentally starting the motors after connecting the battery, this is what happens when you hit the switch by...

Only time I ever smoked an MK was after mistakenly connecting a pair of 4S in series rather parallel! :surprise: It did launch rather smartly with smoke coming out under the dome from the blown 25V capacitor on the F/C board, quite a sight and one I'd rather not repeat... Ken

"Figured out" in American English... Ken

No I started as though it were a new build, I reset the boards to default settings and reflashed everything including the compass, then did all of the calibrations again before the initial test flight. Once I got an idea of how it was flying I made adjustments as needed and I find that unless...

Maybe, send me an email with what you are looking to get for it and we can discuss. Ken

I'll take all that Mk gear off your hands if you're not going to use it, I'll build up another FPV multi and have some spares to add to my collection! I like both WKM and MK and I don't find tuning the parameters on the Mk to be a difficult task but then again I've been a computer geek for...

The board has video in and out connectors, you have to pass the video signal through the board from the camera to the video TX. In general you should avoid video TX in the 1.2/1.3 gHz band if using GPS, that leaves 900 mHz and 5.8gHz to avoid potential problems with Spektrum radio gear. Always...

On my other 330mm aerobatic quads I hang the battery just as it is on the F330 and I've driven those into the ground in some rather spectacular ways including a splash landing in the brook that flows through the flying field, have yet to have a problem with the battery being damaged on the...

Yeah, they are! I think maybe a 1/4 inch between the tips at the closest point, no way could it be flown with a battery on top with these props not hitting the battery or the power leads. I think eventually it will get better motors, performs well with the stock DJI but would have a lot more POP...
