I can't remember the company name, but years ago there was a company that offered a GIANT L2-capable Mosquito called the "Skeeter" that had a 54mm mount.
Always wanted to build one of those, but never did. I think it was 7.5" diameter and only went to like 800' on a J350W which was great for single-deploy.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
