Hi All.I could really use some help, and mentoring, with understanding a flight log!After many successful flights with my quadcopter I decided to upgrade the power pack (Li-Ion batterys). This entailed moving from 3S,3P to 4S,2P. as you would expect…

Lyn Rees replied to Rogelio Flores's discussion Help about 3DR X8+ octocopter coaxial
"Hi Rogelio.
There could be a multitude of contributing factors to this behaviour. i.e. Battery condition - state of charge. motor configuration - are the signal cables wired in the right order. propellers - are they the right order - i.e. counterclo…"

Lyn Rees replied to Seppo's discussion RFD900, RFD900+ - New long range radio modem
"Roger.
Looks like Lanzo may be using the RFD900+ as that has the V1.xx firmware available. only a guess here mind you!
Paul.
Can you elaborate here RFD433? or am I missing something! Roger Ronald said:

Lyn Rees replied to Mergan Chetty's discussion Power Distribution Board Selection
"Hi Mergan.
When I design and manufacture a UAV the first thing I do (after obviously ascertaining what the UAV is being used for) is decide on a power train i.e, motor first. From what you say you are using a U3 (decent choice, I also use a lot of T…"

The short answer is - yes. RFD900x / 868x, and other units, can indeed be used for control as well as the usual telemetry. but as you say you are "new to this". So I suggest you learn to walk before you try to run!
you will find no better…"

Lyn Rees commented on Mike Isted's blog post Pixhawk 2 with Jetson TX2 Build
"The co-ax IMHO has all the advantages of an octo (I have a 1000mm one of those as well that I will,hopefully, get around to finishing some day) and no disadvantage for the reasons mentioned above. It also the ability to use larger props for a given…"

Lyn Rees commented on Mike Isted's blog post Pixhawk 2 with Jetson TX2 Build
"The cool thing with the co-ax is I can drive the motors 4 + 4 so the main supply powers (2 x 10'000, 6S) never meet. The multi copter has a better than 2.2:1 power to weight ratio. In this way I can afford to lose an entire side (4 motor / prop comb…"

Lyn Rees commented on Mike Isted's blog post Pixhawk 2 with Jetson TX2 Build
"Totally understand your reasoning on the safety front. I myself fly a coax quad, along with fixed wings, for the same reason it also has dual power supply from the twin batteries through the full system. the only thing I worry about now is the FC. i…"

"Nice build mate. Any reason why you didn't use the RFD 868X for control, seeing as it has that facility?"

Lyn Rees replied to Ken McNamara's discussion PixHawk 2.1 - JST GH connector specs & ordering in Pixhawk2.1
"Let me try to understand this. Are you looking to crimp GH terminals to a cable? If this is so first of all good luck, I hope your eye are better than mine, they probably are! As an alternative DigiKey stock a pre-crimped cable (455-3074-ND). This w…"
