tomteblossParticipant
efbe; You are right of course. I got a bit ahead of myself there.
Do it like this with this.
tomteblossParticipantYup. You got it! If you got any other questions just ask. That’s what the forum is used for.
tomteblossParticipant1. That will work for example. SmartieParts have solderless board if you don’t want to solder.
2. Nope.
3. You can only use 6 channels safely if you use standard firmware on the D4R-II. If you change it to this with a USBasp you can use 8 channels in ppm mode. The D4R-II only have 4 PWM channels standard. (An USBasp is can be used to flash a lot of stuff. For example a Turnigy 9X, KK2.15 Flight controller, ESCs, FrSky receivers)
4. CPPM (Combined Pulse Position Modulation) is a analog protocol to transfer all channels through on cable in a row. Often referred as PPM. The conversion you are planning to do in the 9X with the use of the DHT module uses three cables to talk to the 9X. Ground, +12Volt and ppm signal. It sends all 8 or 16 channels through one wire. You don’t have to change anything in the radio. Ignore what I said in the first post. Sorry about that.
On the receiving end you can choose to use sbus/ppm/pwm or whatever you want really. If you have flight controller on your multirotor that can talk cppm/ppm you only need one wire between the receiver and flight controller (also +5V and ground to power it).
tomteblossParticipantYes, yes and yes. As I understand it, all FrSky have failsafe which is a great thing to have if your transmitter goes dead or if you loose signal somehow. Channel hopping/changing (accst) is also a great feature.
You have to change to ppm in the transmitter to talk to the DHT module. You don’t have to use it on the receiver.
If you want telemetry from D8R-XP to your transmitter you need to reflash your Turnigy 9X with diffrent firmware. You have to solder an accessport to be able to connect the 9X to your computer though to be able to reflash it.
If you are going to use ppm on the reciever you can use D4R-II and change the firmware on it to be able to use 8channels. It also have telemetry but it is much smaller then D8R-XP.
Turnigy 9XR already have backlight and ISPprogrammer port in it, if you do not want to do this in your 9X.
tomteblossParticipantWeight of the craft plays a huge part in calculating air time.

tomteblossParticipantYou should leave out the comma when writing in the number in KK2. ie 14,9 volt should be written 149 under settings.
tomteblossParticipantThis link should work or remove the / at the end of GAntonjos link.
tomteblossParticipantJust to make clear of what Agent CAL said, arming on KK-board is done by throttle down AND rudder right. Disarm by throttle down AND rudder left.

Plus/(+) seems to be on the inside/top on the plate and the bottom/underneath of the plate is the ground/(-). Just make sure to clean the hole so the to copper plates don’t connect to each other when your done.
tomteblossParticipantBe sure to connect the antenna first before you power up the transmitter.
tomteblossParticipantThe servo shouldn’t be on the same BEC as the receiver and FC-board because it makes to much noice/interference. The FC can even reboot in mid air if your unlucky.
So only FC and receiver on a seperate voltage supply.
tomteblossParticipantTo explain simply, the left side is the voltage led in to the circuit and the right side of the drawing is the voltage connecting to whatever you want to hook up to 12V.
+IN is the red wire on a 4cell battery. Either from the main or the balance lead. +OUT is +12Volt.
GND is the black wire. – (minus, 0 Volt) . This is connected all the way through the circuit.
EDIT: schlagbohrer beat me to be the first with the answer.
tomteblossParticipantI crashed and cracked the tougher tilt-top this weekend on a tree. So I seem to need this one instead. So the question is, should I wait for this to be released or buy a replacepart from the store? It seems that that the release party for this little part is due any day now?

tomteblossParticipantSame for me too.
