Personally, I would not even consider running a controller that has this potential issue beyond initial testing - I would address it before any extensive driving. I don't care who says its OK - it looks like a short waiting to happen. I suppose if(when) it does short, it will be covered by warranty, but the batteries won't be covered(or the chassis and melted Lexan body). Just my opinion based on 8 or so years of brushless car/truck use. :)

Dear Mike,

thank you very much for this statement. I drive brushless boats, cars and flying objects ;) for years and I always use my own brain.

Look at the images I have taken of my V3 MMM and you will see that the battery side of the bullets hit the heatsink. This is a very serious problem - and that is the reason why I wanted to warn other users.
