"Thanks Paul that is encouraging.  I will stick with the pixhawk rather than defer to the A3 as the intention is get dgps precision for camera positioning (without paying the ridiculous DJI prices). I am also looking at using a DrotagX as I am…"

Darrel Maddy replied to Samson's discussion Is it possible for me to build a DIY mapping fixed wing drone?
"That build is almost identical to mine!  Have you flown it yet? Weather has been crap here so no chance for me yet, Have you added any additional strengthening beneath the camera?  I am probably going to use a servo gimbal (2-axis) but…"

"Just to be clear, it is the radio that wont connect or the vehicle? Does MP recognize the radio, on the SiK radio tab? Or are you just having trouble connecting the vehicle with MP?"

Help with 3DR radios in MP

I have several pairs of 3dr and clone 433MHz radios which were all working fine three days ago. They are all recognised using the standalone 3dr SiK radio software and when connected through that software the RSSI is ~180+ . The issue comes when I try to connect in MP when everything just times out. I have tried everything I know, including reinstalling MP and yet there is still no connection. I have tried this with both a 3DR Pixhawk and a drotek dropix (different cables and…See More

Pixhawk problem with aileron output

I have suddenly developed major jitter on the extreme ends of the aileron output from my 3DR pixhawk. I have checked the servos and leads with a servo tester, furthermore the ailerons function normally when plugged directly into the RX,  All other channels are fine (i.e. for Ele,Thr and Rud) except when I plug the ailerons into any of them and then they jitter!  I have changed the servo-Y connectors and the SBUS leads but nothing changes.  I have the wires outside of the model now and there is…See More

Customise display text sizes in MP

I have just recently purchased a vufine for use when flying my drones. Sadly my eyesight is not what it once was and the MP display on the lens is difficult to read i.e. text sizes are too small for my eyes. None of the usual windows scaling changes make any difference and I could not see any way to change text sizes for the HUD in the configuration menu. Is there a way to increase the text sizes?Thanks in anticipation of your help.DarrelSee More

Ya I dont know how to use "friends" either. it just said that i need to be friends with you to leave u a message. That is alot of X6's. I just made the launch ramp for mine, but still have to put a hook on the plane, and get a bungee cord. Where is your hook located? I have read that 50% between nose and cg is a good start point. Then adjust from there. what size batteries do you have? What motor/esc are u using? I am using a tacon bigfoot 15 900kv 2826, 50A esc, 4400 80c 4S battery, and 10X4.5 prop at the moment. Waiting on a 10X6 foldong prop and a 11X8 folding. I know that is too much for my motor and esc, but I am looking for max flight times, not sporty flying. 

Once I get mine dialed in and it flies a perfect grid, I am going to either put a nex5r in the front for mapping, or 2 canon sx260hs in the wings for ndvi. I dont always have someone with me, so i need to get that bungee system working. I want to get cameras on this thing asap and start making some money!
