"@Kevin: I agree with you completely but regarding flashing i would like to include a slight warning, because once you have flashed your esc there is no way back. Some motors are not so compatible with simonK or blheli and start stuttering. This…"

"That's what i call real development! That kind of datafusion would take an university professor probably his academic lifetime with a good feeling that he has achieved something in his liftime....."

"Yeah, printing the running direction on each arm of a simple quad reveals the real expert. Very nice build BTW."

"@Jan Boermans: Thank you very much for also sharing your idea! I didn't know that those chepo pc RC adapters would do the job! - Link added - Cheers Rob"

"Thanks Rob for sharing. It triggered me to look for another alternative way. I used a 2.99$ hobbyking USB to serial convertor to flash the MTK GPS. After some trials it worked perfect. See attached schematic. jan"

"@Roberto Navoni: Hey, that is Bruce Willis visiting your lab! Cheers Kraut Rob"

"Generally this gimbal is a very good idea, because it get's rid of the arduino328p crappy pwn output and on the other hand it is possible to adjust your camera to a POI with extra gps (or maybe mavlink gps messages from the FC). The z axsis…"

"From what i read the HK ublox is preset to NMEA but has an eeprom on board, so you can upload the 3DR-Ublox.txt with an ftdi and the ublox center. The only real catch is the cable wiring, like on some fpv ccd cameras they mix up the colors so the…"

"Because Ublox are dirt cheap and way better than mtk. http://www.hobbyking.com/hobbyking/store/__31135__NEO_6M_GPS_Module.html. Even with usb and TTL serial for the FC it is cheaper than you think: http://www.ebay.de/itm/271176495992 ...... end…"

"Actually i am using a ublox variant that has an eeprom but thats another story. I know that the ublox datarate will eventually drop, depending on the configuration (ufo hans/arm-o-copter did some work on that subject, he saw a drop down to 2,5Hz…"

"Question asked and self answered - so deleted .... Cheers Kraut Rob"

"Now i have a good RC logo idea: http://www.ritterruestung-handgeschmiedet.de/deutscheversion/werdegangharnisch/bilder/riefelharnisch.jpg Too bad the logo competition is over!"

"@patrice: The main difference is that arducopter is still armed (10sec or so) if the rotors stop, a NORMAL configured multiwii is disarmed when motors stop, that is safer. @criro: That was a bad idea. Writing parameters may be different, but keeping…"

"My best wishes for your restitution. Perhaps thats why i implemented a killswitch in my own copterproject - i really got used to it after landing - killswitch and nothing in the world will rearm this thing unless the next powercycle. Even if i would…"

"If this is like skywalker quattro 20 than you can flash BLHELI. SimonK is for atmel. I realy like the sil-chip / blheli combo, anyways."

"I don't know if it's a good idea to ziptie lipos. I think they need some "breathing" room. BTW the normal alarming voltage on a std. cheapo liposaver is too low. When the cheapos beep you are already damaging the lipo."
