Checks on my order before I pull the trigger

I've wanted to get into Multirotor/FPV for some time now. Im not a pro and more or less just want to add it to my "big book of cool stuff i do that women will never care about!"

I live up in the Mtn's of Colorado (US) I really want to capture some of the backcountry when Im out snowmobiling, hiking... Hard to show people with just blah phone photos!

To that end I've been looking that the Tarot 680. I like the idea of having the extra lift at higher elevations.

Im having trouble landing on a motor/prop/esc/battery config... I've been trying to use eclac to help but it seams to just be messing with my head more than helping.

I want a good balance of speed, control, lifting power and flight time...

Heres what I have right now
8x Multistar 4822-490 with 17x5.5 Props and 30A ESC's
2x 10,000/3s 45/60c mAh packs

The base weight of the 680 is 600g (I've set the model weight at 2kg for the added 2D gimbal, radio, GPS, go pro, etc. )

According to eclac, I will get roughly of flight times of 9min of flight, 17.5min mixed, 20.8min hover and a max speed of 15mph. I'd be at roughly 55% throttle for hover. This seams pretty good to me. is it or am i kidding my self?

I'd love any input on this before i buy all the gear. Next up with be the FPV, retracts, gimbal and auto pilot questions. 1 step at a time!

it's a lot of weight in motors for the frame size/props you can fit. if you could get 17" props on it times 8, your gonna need to down size the batteries, down size the motors to hit a sweet spot. 4014 would be somewhat big but they like 18" props best.... 3520 would get you in that same weight/size/power. just having 8 instead of 4 will make a huge difference and we routinely fly 2kg quads with 3510, 3520, 4008 and 14-15" props. i'd look towards 10-12amp hours of pack instead of 20. when you get into this grams start being seconds of flight time so anything you go over adds up quick in inefficiency..... altitude is a big deal. i'd talk to some local mountain guys and see what they run on such a size frame.

I thought this frame was a Hexa.... am I wrong?
At this size it would be very close to our HC-650.... This is 12" props MAX....maybe 13" if really 680mm.
If I am correct in size & spec, then aircraft would max out with 2814-770 or U3 motors, 12" props and about 4300 grams AUW.
I am confused about the 8X motors and 680.... perhaps I have the wrong aircraft?

That's a pretty big setup for a hiking/snowmobiling package. I'd go with a disco or, gulp, a phantom if it's just a gopro flyer. Everything would fit in a backpack easy peasy, good to go!

I agree. Contact Team Black Sheep about their Disco Pro. The 17" props aren't going to fit the 680.

Yeah I'm showing my newbie'ness. It is a hexa and Yeah it will only fit the 13's.

Right now Im at Hacker A30-30M UAV (550kv) with a 20A UAV ESC and 13x5.5's. It seams to get me a good balance of Flight time, load capacity, speed, Hover at 60% throttle.

Im not really a fan of the RTF's, to me that takes all the fun out of it. I also want a platform that I can test the limits of it.
