here is my eEZrun 35 ESC...
the cut out so that my A123 pack would fit...only notched it so that the pack would fit and stay put...
with the pack...
A123 pack
With everything installed...
With the lid on...
you can see that the body doesn't sit level...good enough for me until I get longer body posts...
and yes i am aware the wing mount is fugly...but it works well until i change back to stock mount
quick vid showing the esc...
