congrats, i think today i will work on my zmr project. it seems the taranis RX can give voltage too.. it also says if you do not set the RX fail safe it will remember its last signal and hold it possibly flying off..
im starting to wonder if i got over my heard with this damn radio.. at least i have it for when i am able to understand it.
The Taranis has the ugliest interface ever. I thought OS2 was bad. The FrSky failsafe is one reason I like it. After you bind and reboot everything, turn the transmitter off and click the bind button on the receiver. This sets failsafe so that on lost signal the copter will fall out of the sky.
As for being in over your head, so long as there is a lifeguard, I know of no better incentive to learn to swim than being in the deep end of the pool.
i do have one question.. when you do not use a ESC with a linear BEC ( this is the one you do not have to disconnect the power wire going to the FC from three of the ESC... ) the other being switching BEC which you do have to disconnect 3 of the 4 power wires from the ESC before plugging into the FC>. im using the one that have no BEC dys Ns20 BlHeli ESC. so i did buy the lightest UBEC i could find.. from what i understand, i solder that to the power on the PDB, and then i can plug that into either the FC on a unused motor, or you can plug it into the RX too.. is there a advantage over one to the other?
sorry to high jack your build.. but figure this info would useful here for other builders.. i can not say iv seen this touched much.. i know you are using the polou to get the 5v instead of the lightest UBEC... but i do not remember it coming with any wires to attach it to the FC, just 2 sets of pin. so yeah trivial im sure, but if you not done it yet it may as well be like rocket science. laughs.

Hijack away! I am sure I will do it to you someday.
I like the Pololus for their size. I have a few Suppo BECs around here but they are much larger so I don't use them unless I am building a larger machine. I haven't powered a flight controller from an ESC in years. I have never powered a flight controller from a receiver.
My thinking is this (and it may be seriously flawed). I want the flight controller to be as directly powered by the lipo as possible. If there is a brown out, I want anything else to take the voltage hit. I want the flight controller working as long as possible so it can return control to me so I can fly home. If the receiver browns out and comes back on, great! I fly home. If the flight controller browns out it will likely reboot mid-air...
Most ESCs come with a 3 pin servo connector. On a quad, I remove the power and ground wires from all 4 ESCs and replace the 3 pin connector with a single pin connector on 3 of the ESCs. This gives me 3 ESCs with only a signal connector and 1 ESC with only a signal wire going into a 3 pin connector.
I then connect the Pololu or BEC to the PDB and use servo wires as the outputs. I push the crimped ends of the servo wires into the 3 pin connector off the last ESC. This gives me 3 ESCs with only a signal connector and 1 ESC with signal from the ESC but 5V power and ground from the Pololu or BEC. I then connect the wires to the flight controller as per usual.
I have stacks of Arduino and servo wires here. Stacks. I also have 1,2,3,4 and 6 pin connectors in bags. I cut, crimp modify and create my own cables in the colors I want at will. I do not rely on wiring from Chinese electronics vendors very often. If I screw up (just call me SmokeTestHarry), it's on me and I have no-one to blame but myself and I like things that way.
