I'm wanting to build a Hexaquad. I want something that can handle some weight for photo/video. I've been looking around and ran across Tarot. They look pretty nice. Are the well balanced stable and reliable platforms to build on?

tarot frames are grate but the best feature to me is the folding.
motors are the most important thing motor prop combo calculate estimating the payload you plan to carry.
what is your budget ?
Well, budget is a none issue now. I found a nice hexaquad on craigslist.
Tarot FY680
DJI 3508/415KV motors
E600 ESC
Naza-M V2
DJI Phantom transmitter
SkyRC charger
DJI H3-3D Zenmuse Gimbol
Is it a 6S Battery?
Because of the 415KV motors... I guess you can fit at most some 13 Inch props.
With my motor mounts i fit 15 inch props on 580kv motors with 4s. Enough power and a constant hower with TOW of 4kg at 25-30 amps....
Please let me know what you get out of it
I'm not sure what all the numbers mean. As mentioned, I'm very new to all this and am still trying to get a handle on everything. But here is what the battery is
ReadyMadeRC Lithium Poly
10000m
30C
6S2P 22.2v
30C(300.0A)Cont 60C(600.0A)m
Not sure what all that means.
The props measure in at 12-3/16"
The KV Rating of the Motor is most likely translated with "turns per Volt"
low KV rating means lower turns with the same voltage as higher kv ratings. Lower kv motors have more torque than high kv motors. its the same with a car. Diesel-Engine with low rpm produce generally more torque than high rpm petrol engines
6S2P means, that inside the battery pack there are 6 single cells attached in a row to add up the voltage from 3,7v 1 Cell to 22,2v for 6 cells. 2P means, that there are two cells for each one if the 6 parallel. So over all you schould have 12 single cells inside the pack. 6 in row and to each one of the 6 one parallel to boost the capacity
So I have a charging question. My multicopter came with a Skyrc iMax B6 mini charger.
For this battery, how would I set the parameters? As in what would I set my charge current and my discharge current?
Charge current should never exceed 1C which would be in your case 10 Amps. As i recall the Imax could never reach this current. I had one and it was not higher than 3-4 amps while charging.
You can take the "Balanced Charging" Programm and just set the Parameters for your S-Rating, 6S, and go ahead with a current lower than 10 amps.
Why do you want to discharge? Well, the Copter discharges the pack with aprox. 30 amps...
Yeah that's what I was able to figure out. I'm charging @ 6amps.
What is the max volts I can take this to? Is it the 4.2 volts? It seemed that the iMax was charging past that so I stopped the charge.
As far as discharge? It's just an option that I see. Plus I've heard that you want to discharge them for storage. Just what I read.
Ah ok, there you go.
Basicly in the Balanced charging mode the imax shouldnt exceed 4.2v per cell, in total it is 25,2v i guess. It is possible, that the overall voltage of your pack is already displayed with 25,2v in the loader screen and it keeps charging. That is the balancing of the pack. Balancing means, that each single voltage per cell is checked against each other to have the exact same voltage per single-cell. This is crucial because the cell shouldnt have to much difference in voltage against each other. Just keep loading until the charger stops.
If you see a voltage in the single cell screen, by pressing + while loading, above 4.2v like 4.23 or something... it's ok. loader will discharge this specific cell later on in process.
Discharge for storage.. that is another thing. It is best for the pack, if you store them "half-full". Storage means several month without using. For that the loader should have a specific programm like Storage or something similar. You do that most likely after the last flight otherwise the discharge could take days... i know what i'm talking... tried to Storage load a 16000mah pack... took 15 hours to discharge thorugh the loader.
Almost forgot... I Discharge my cells during flight until i have 3,3-3,4v per cell. You don't want to go much lower. Below 3v the cells could get damaged beyond any change to function ever again. For a start you should set the voltage alert in the naza to in first stage to 21,6v and the second stage to 21V. This should warn you far before a cell gets damaged
