I picked up the 1/72 Revell Germany MH-53J "Pave Low III" kit ($10.00 I thought that was pretty good!) and was curious to know if there are any outward differences between a J and M model. I know 'M' models are upgraded 'J's but are the changes only in the electronics?
I plan on doing an in-flight display so interior changes aren't a big concern for me but I wanted to know about any new antennae bumps or plades. I haven't been able to see any differences in the web images I've collected.
