Hi Again, Oosel!

Here's a link:

Our fellow heli pilot davidhnsocal has a post at the above link that he has retro'd a Mega and the shaft size was the same as the stock Fusion motor.

Anyway, read that thread and yes, the "Corona Mega" search phrase came up with almost two dozen results.

For what it's worth,
