Hi,first up - my problem is with an APM 2.5 clone (arduflyer) - I know some of you don't want to assist with hardware not bought from 3dr store (which is fine) so I'll make this point clear at the beginning so you can stop reading. If you're still…
"@Gregg Fletcher: if you think this sort of activity is not regulated in Australia you're dreaming. It is nigh impossible to do commercial aerial photography with RC helis in Australia - you'd need a UAV operators license to do it legally and get…"
"This is a nice idea for servos but if I understand your setup correctly I wouldn't recommend using this for driving ESCs on a multicopter. The reason is that you limit your update period to approximately 2 ms * 10, which is 50 Hz. Many standard ESCs…"
"Interesting. What eposure mode does the imaging sensor have: is it global shutter or rolling shutter? What frame rate can the sensor run at ? (I have a gut feeling the optical flow computation on the ATMega will be the limiting factor w.r.t frame…"
"I'm not familiar with Leica Photogrammetry Suite but I was wondering whether this could be done in PhotoModeler Scanner? This software package would still be more expensive than the Hexacopter itself but maybe it is cheaper than the Leica package…"
"I guess this is for the ready-to-fly RC crowd. If you just want a stabilized multicopter and can do a bit of soldering you're probably better of with this http://www.kkmulticopter.com/ (that website just brings together some information that is…"
"A few more thoughts regarding the 2.4 GHz video TX + 2.4 GHz RC link: if you use Spektrum/JR DSM2 it is not a good idea and here's why: http://www.rcmodelreviews.com/dsm2flaw.shtml

"Not talking from personal experience the general consensus on the rcgroups FPV forum seems to be that it is not a good idea to use 2.4 GHz video alongside 2.4 GHz RC. It appears to work but not reliably, especially with increasing range."
"Vibration - and its effects on MEMs sensors
Heading - need magnetometer
Barometric sensors may not work in the rotor downwash
Pitot tubes won't work in the rotor down wash
Ultrasound sensors for height above ground may not work due to vibrations…"
"A camera that looks the same and has the same specs has been available on ebay for $25 incl. shipping for a while now. Also, this is not the only cheap 2.4 GHz TX. Have a look on the FPV forum on rcgroups for alternatives and you see that there are…"
