Marc LE BRET replied to Randy's discussion ArduCopter 2.5 released!

Marc LE BRET replied to Ruwan's discussion Share your drone info thread

DeveloperJohn Arne Birkeland replied to Marc LE BRET's discussion APM2 and Futaba R6107SP PPM Sum

Marc LE BRET replied to Marc LE BRET's discussion APM2 and Futaba R6107SP PPM Sum
"Hello, It is like APM2 is looking for an 8 channels signal. If the PPM sum is with 7 (Futaba) or less, there is no luck. I ordered a FrSky Futaba 8 channel PPM sum compatible receiver. Keep you in touch if I have some good results with it. Marc"
