Check this German FC system looks like a competitor of MK any one has one that can coment? http://www.service-drone.com/en-de/technology/multirotor-flight-control
They copied MK's design. Their boards are about 10 times the cost of MK stuff. I am intrigued by the GPS and flight control improvements.
The curious thing is that it looks like they are in Germany not in the Far East or elsewhere if they actually copy I'm sure MK is all over them, yep for sure they are way way more expensive than MK I notice the claim that their FC board is 32 bit vs MK is 8 bit what ever in this case that really means
remember, some of the MK software is open source, so that may have contributed to the ability of folks to clone the hardware, too. but at 10x the cost (if that's true), it'd be interesting to see what the improvements are.
The boards do look strikingly similar. Looks like litigation waiting to happen... The pricing of the copters and the boards is, err.., stratospheric. Andy
