Congratulation Holco.

wow your vibration isolation looks very good ! It would not be a problem to use it in X8 config ?

Thanks

Boris

 

[holco]

Thanks guy's

Boris,

X8 is also possible, but when you want the easy removable boom system we have
to use the V1 system from the hexa, the V2 plug system only support one motor and one
led or buzzer.

Mario

V1 plug system,

Cool

The kratos in combo with the AQ, and the distribution board getting designed by tilman, would be a beauty !

Also nice Boris and for sure posible, but max 5S and imo not useble for careing the RED.

 

[BorisS]

japp i agree, but the ultra ESCs are coming, hope they will do a similar board for them !

 

[holco]

We use MGM ESC's on the Kratos, max 6S and real (no Chinese) 60A, imo the best money can buy and with actif braking, testings shows realy good results with cool temps in combination with the Plettenberg Orbit 15-24 motors with Xoar 14x6.5 prop.

Mario, this rig is just flat out stunning, well done!

 

[holco]

Thanks tstrike

 

[holco]

After testing a lot of motors we decided to go for a Plettenberg Orbit motor for our Flexacopter Kratos

 

[holco]

Made a prediction of the flying time with a theoretical AUW of 10Kg for the Kratos.


Snapshot of the video at 1256g lift, this shows that there is +/- 7,65A running.

7,65A X 8 = 61,2A total


80% of 16000mAh lipo = 12800mAh or 12,8Ah


12,8 ÷ 61,2 = 0,209 hour


0,209 X 60 = 12,54 minutes total flying time


Seems to me a very nice result

 

[holco]

One step further
