Hey,
I love multirotors and I have a Quadcopter that I have built myself so I am not a total noob but I am not super knowledgeable either since a friend helped me build it. The only part I really don't understand is the ESCs, my friend programmed mine and while I want to build a FPV tricopter, I don' want to have to do this. I see there are pre-flashed ESCs but I don't know if they are compatible with what I want. Do pre-flashed ESCs come with different settings that I need to be aware of?
Basically is all this stuff compatible?

>The only part I really don't understand is the ESCs
So you're comfortable setting up and tuning a flight controller like a Naze32? That's really more important than reflashing ESCs. It's not too finnicky with Cleanflight Configurator or similar, but there are a lot of steps and it's an important and surprisingly time-consuming setup.
The ESCs you chose already have SimonK firmware, so they should work great without programming/reflashing (even those that don't have multirotor firmware still work, but SimonK or BLheli improve response considerably and let you crank up the gains more). Brushless ESCs and motors can be reversed by simply swapping motor leads, make sure to check all the directions and response before you put the propellers on.
I'd also avoid the raceband transmitters, ImmersionRC/Fatshark keeps introducing proprietary shit to try and box competitors out of the market and force customers to buy new shit, and the raceband is just another example of that.

I am not rewriting this shit on another thread, fuck off. I will however search next time before posting.

Oh yeah I comfortable with the Naze32, not really any other flight controller. My quadcopter has a naze32 and while I use Baseflight instead of Cleanflight, its all the same really. I don't know every command you can possibly run in Baseflight, but I know enough to setup a Quad/Tri-copter.
I knew those ESCs had SimonK cause of a thread I found but what I am confused on is do I need Brushless ESCs for Brushless Motors? I found some Brushless ESCs and they are really expensive, what are they used for?
Also I didn't realize my A/V transmitter was a raceband or even realize what that is but I'll fix it and get something else. I have the Fatshark Attitude V2 for a headset.

You most likely already have brushless motors on your quad, and don't need brushless ESC's, most ESC's are already for brushless motors. Brushed motors/ESC's have 2 wires between them and run DC. Brushless motors/ESC's have 3 wires between them and run AC.
Also, there's a programming board in the accessories tab in the hobbyking link for the ESC's, but it's out of stock from the AR warehouse.

>don't need brushless ESC's
let me clarify that, a brushless ESC may not say "brushless" in the name, as long as it has 3 wires going to the motor, it's for a brushless motor. It looks like all of the ESC's in the multirotor section on hobbyking are brushless. I've not seen any multirotors running brushed motors aside from the small $20 micro quads.

if it's not for brushless motors, it's not called an ESC. For brushed motors they're called FETs

You haven't been in this hobby very long, have you?
Both brushed AND brushless ESCs exist, and there is a difference. Both brushed and brushless ESCs usually use field-effect transistors (FETs) to output power to the motor leads. A brushed ESC simply takes a PWM input and translates it into a DC output of some duty cycle corresponding to the throttle position. A brushless ESC is similar but outputs tri-phase current across three motor leads and handles motor switching/commutation (electronically) as well.

actually it's been a year now, didn't know about esc and fets, hue.

I dunno shit about tricopters; what is the point exactly? is it just a unique look?
I do know that there are counter-rotation forces present from the propellers--where the props exert a force (on their rotational axis) in the opposite direction that they are turned.
with a quadcopter the forces can be easily equalized because two of the props spin in one direction and the other two props spin the other direction....
how are these forces equalized on a tri-copter?
