Selecting the right Flight controller

I'm fairly new to multi rotors. I've ordered my frame a T680 Pro. I'm planning on running: Multistar 4225-610 along with 13x5.5 Props.

Im looking for the best, most versatile flight controller. Im looking for the basic pos hold/alt hold. but I also want some more advanced features like tracking, waypoint nav. I'm not sure whats the best one to go with.

In my system I want FPV, OSD and AutoPilot

In the auto pilot I would like; Pos Hold/ Alt Hold/ Waypt flying. and tracking if at possible

Right now I'm looking at the pixhawk for the AP. please help me learn about the rest of the system I need

In a similar situation I would choose Pixhawk but it's not the drop in and go type unit the A2 is. OTH, that difference is one of the things that makes it my preference.

You said "versatile". There's really only one choice then. Pixhawk/Arducopter does just about anything that you could want.

Buget isnt a non-issue but I would rather spend more money on one thing I need than spend it first on something i don't like and later one something I do.

Im starting to get the feeling I really wan the Pixhawk

Would you minding lining out all the individual parts I will need for a full FPV, Autopilot system Flight control system

I recently wrote this for somebody else, but might as well cut and paste it here:

Here is the list of items you'd need to purchase. Most of this will come in a package from 3DR on this page:

- Pixhawk
- No PPM Encoder
- No Airspeed sensor
- External USB and LED module could be handy if the Pixhawk is buried in an airframe
- Telemetry Radios, 915 MHz
- U-blox GPS with Compass


We do need to find a solution for the Power Module. If your machine is going to use 4S or less, and less than 50A at full throttle then you can use the 3DR Power Module. If you will use more than that, you will have to figure a solution. 3DR is working on a 6S board but it's not ready yet. I use a custom voltage regulator and voltage divider, and skip the current sensor altogether, although I have a solution to that if really needed. HobbyKing have a 6S power module, but I have seen and heard some bad things so don't recommend it.


You may also want to get some longer 4 and 6 wire cables, depending one where we want to put the GPS and 3DRadio. I typically put these out on an arm to try and separate all the Rf sources and receivers. The cables that are included are OK to keep these on the center frame, but if you want to put on the arms, you might want to order these:

https://store.3drobotics.com/<wbr>products/df13-4-position-<wbr>connector-10-cm-1-2

https://store.3drobotics.com/<wbr>products/df13-6-position-<wbr>connector-30-cm

https://store.3drobotics.com/<wbr>products/df13-6-position-<wbr>connector-45-cm



Just give you some options.


GPS Mast to raise it up. These are slightly flimsy. I can fabricate something better here on the mill, but that gets expensive fast.

As for the FPV stuff, that's really a separate topic altogether.
