Hello,

     Does anyone have flying experience with Mikrokopter Okto:

    - 8 x MK3644 motor
- 8 x Propeller Size 12” - pitch 3.8
    - GPS On
    - total weight up to 7 kg
    - Wind up to 61 Km/h

I would like to know if it is possible to do offshore inspection with this configuration.

Thank you,

João Marcelo Corrêa

Have Fun ;-)

Hi Marcelo,

I fly your configuration in a carbonframe and wouldn't try it.
I'm also wondering about the reduced flight time in these conditions.

But at least, like SilverSurfer wrote before, "try this wind at land first"

Take care!

According to the manual of the 6S12 the copter is airworthy up to 6 Beaufort (page 59 http://files.mikrokopter.de/ARF-OktoXL-Manual_(en).pdf)

Hi Duxi, thanks. Yes a maximum value is reported with safety margin considering maximum recommended payload value.

Hi Joao,

Don't forget to consider the bad influence of seawater /salty humidy to your copter.
It's not only wind that can give problems...

Good luck and best regards

Hi Peter, thanks for the alert. To avoid these problems, I am studying the product to protect Copter electronics https://www.youtube.com/watch?v=IPM8OR6W6WE.

    - Wind up to 61 Km/h

I have flown photo operation where we measured 44 km/h wind at ground level, the weather forecast had only stated 33 km/h. This was with FASE G3 (Octo, LiPo 6S, Double Quadro V3 BL-Motor-Ctrl, carbon frame).

I have at another operation measured wind speed at 49 km/h at ground level. We cancelled the thermographic inspection because too much risk to fly with expensive camera. This was with FASE G2 (Octo, LiPo 4S, BL-Motor-Ctrl V2, alu frame). I did a flight on location without camera. While it was possible to control the micro-copter I would not recommend it.

Too much wind makes the flight inprecise. This means it is difficult for inspection tasks where you want to be close to an object, building, tower etc.. Strong wind is a problem, but wind gusts is worse. Also flying in between building or objects makes wind more complicated to predict, wind speed change when you get close to a corner or move above roof top.

We always measure wind on location to get an idea about what to expect higher up. Problem is the higher you fly the stronger the wind is. However I do not have a method to determine the wind at 20 m or 50 m height, I just know it will be stronger. AFAIK wind speed in weather reports are measured 10 m above ground.

When you state 61 km/h is that at ground level or at the highest point where you will fly?

Hi Foersom,

Thank you for sharing your experiences.

In the case the wind of 61Km / h with altitude of the Copter to 80m of the level of the sea. For flare inspection and wind turbines. Example of work done by company in Europe which customized itself Copter: http://visualworking.com/uav-wind-turbine-inspection/
