Yes, the Mega is BB on both sides of the shaft. No Complaints on the Mega.
I am using the CC Phoenix 35, newest version from
www.roffeetvhobby.com It was $180 shipped overnight to my door, COD. I think the combo is usually around $150, $130 if you go to the 25A ESC. I LOVE the CC ESC. It is good and solid, and the service is GREAT. I called them, and the owner got on the phone and helped me pin down a bad RX that was causing the ESC to shutdown for about .5 seconds a couple of times per flight. Since then, not a glitch in sight.
For a while, CC was offering free upgrades on the older ESC, maybe call and ask them (the new version has two circuit boards instead of one).
As for the Dino powered LMH.. I thought they don't really have an exhaust, more like a little tube that spews oil onto the main gear, which then re-distributes the oil on anything within 20 ft. I imagine that would be really loud!
