Warning - Kcopter flight controller flaw.

I've encountered an annoying issue with the otherwise seemingly quite interesting Kcopter flight controller;

Despite the quite attractive features on offer i can't recommend them simply because the one I've received appears to have the standard mounting holes drilled slightly off in the 4 corners. They all appear to be 2 or 3mm short of the standard lengths. I took a picture to illustrate by placing it side by side with a correctly drilled Free Flight controller;



It's a shame because otherwise the option to buy the board with different sensors or no sensors and add your own was quite interesting. I've just spent the last couple of days slowly getting mine to respond properly when i realised the holes where off - i was quite annoyed.

I'm going to try drilling the holes wider and see if i can get them to fit somehow, but i shouldn't have to worry about getting my drilling straight - it should have been done right at the factory :-\

Hmm they advertise this board as 50x50mm and clearly its not  > I wouldnt be to pleased either have you managed to get any code sorted out for it, I think I read some where that there is some thing missing from the board to that will prevent it being used for development or some thing like the that

I did manage to go to all the effort of successfully soldering an MPU6050 sensor to the board (just the gyro and acc version) and installed the latest version of baseflight before i realised the holes where out. It only took me 2 days (on and off) ::)

I have managed to mount it on the nylon stand offs in the end though - i used longer stand offs underneath and was able to bend them all in slightly for the flight controller layer then out again for the protection cover layer above.

I'm going to try it in my new mini quadcopter when the 2 missing motors arrive (hopefully monday) but i am still annoyed as i don't think such basic manufacturing mistakes should happen and it lets down a potentially quite good flight controller. Also i worry about it throwing the board off perfectly level as I'm bending the nylon supports to get them to fit. I'm sure it will work well enough though.
