Mounting the YGE 200 HV on Mikado Logo 800 Xxtreme

Disappointment.  That’s the feeling I had when my brand new Mikado OEM YGE 200 HV arrived for my Logo 800 Xxtreme  and it wasn’t in anyway manufactured to fit the helicopter mounting points. So what to do?  Velcro or cable ties weren’t the answer. Not just because it would cheapen my ‘no expense spared’, premium top of the line (?) helicopter but because it would reduce airflow to the big ESC and crush the capacitors (especially in a crash). Answer, build your own adapter mounts.

Here is a picture of the problem. Four mounting points on the ESC heat sink naturally won’t mate to the 3 mounting points manufactured into the helicopter frame. The heat sink mounting holes are also further apart (in both directions) than those on the frame.

The problem.

The problem

So courtesy of a friend and his trusty CNC router the mounts pictured were born from 3mm aluminium plate. Many thanks to Dave B. for this.

Mounted to helicopter. Don't forget the locktite. There's not a lot of thread in the CF mount holes.

Parts List:

  • 4 x M4 x 10mm counter sunk screws for frame side attachment of standoffs.
  • 4 x M4 x 10mm cap screws for ESC side of standoffs
  • 3mm aluminium plate. The length I got from Bunnings was already 50mm wide and a perfect fit for the frame even without milling.
  • 1 x can of etch primer.
  • 1 x can of metallic red.
  • 4 x 25mm Nylon PCB Spacers.

Final words

I mounted the ESC a little higher rather than lower hoping that it would protect the ESC in event of nose in crash. Not that I’m planning one. I am also toying with the idea of drilling some weak points into the standoffs so that they might sheer off in event of a crash. I’ll add those pictures to this article if I get around to it.
