Nice workspace!

I didnt try jet normal landing gear with AV200 360. Try to find some solution

Did u have any problem on customs or went everything ok?

p.s.
And Skyjib is a big and nice lady, what u think?

Coptaire u have always negative posts. Is there any positive in you?

Just if u want to know delaers price are bull shit. They are from 6-14 %.
U must sell at least 10 pieces to get one.

Resellers have a commercial interest to sell these highly priced items, the margin will be better.
U are wrong. Not to mention shipping cost, customs and all other shit.
Not to mention, everyone wants some discount like 2-3% and so on.

U really makes me mad with every your post.

My 2 cents.

The race to the heavy lift must be guided by a good reason to this.
Why using an H bomb to kill a fly?
A big fly won't be convenient for some shoots or very dangerous.

The reason for this has been on the manufacturers website since much earlier this year, to be able to carry a professional grade video camera such as the RedCam or other equivalents, i.e. cameras in the 3kg range. Not all movies are shot on DSLRs or GoPros
Exactly, you have payload and payload! Be precise: which RED are you going to fly? the REd epic at 50 000$ or the RED Scarlet-X (recent) at 10 000$ (body only) ?
A pack of 6, please, flying RED is so common nowadays!

As for the motor choice, I have found that getting the most efficient setup does not mean that you will have the most stable setup, as you need to consider whether the motor has sufficient torque to accelerate the prop fast enough, and doing that means having to sacrifice some efficiency. Its basically a balance of all factors that ultimately depends on what the owner/operator decides is their optimal solution.
You told it semi-wrong.
A motor propeller matching is an encounter between 2 curves:
- A brushless motor has a decreasing torque with RPM
- A propeller has an increasing torque with RPM (and air characteristics)
The right part of the curve is were the motor is at best efficiency, where the electric power is converted to mechanical power, not heat...
... Except if you plan to use your brushless to fight against winter cold!
It is an objective criteria, based on the motor/prop couple of your choice: You will use the motor at best efficiency (least heat, least consumption) to reach a targeted thrust.
The only thing the "operator" can do is to choice among several propellers (clipped or not, and always balanced) for a given motor.

It is all about physics (test bench for targeting performance) and nothing about ...empirism.
