PS Is there ever going to be an outrunner motor with similar weights and power characteristics so I can blow this gearbox stuff? It seems the Axi's, Pletti's and E flite's are still fighting with weight and mounting issues as we speak. I eventually threw away all my inrunner stuff on the smaller planes. Just hoping it will go that way with the big ones also.

I am not sure where you read that Pletti's were heavy, they are as light and turn same or better rpm (30-10 Evo) than the Hacker's that I have witnessed. Problem with outrunners is they have a bit lower efficiency so you will have increased current draw for a given rpm.
I am also not sure what mounting issues there are? I use 1/8" light ply laminated with a single layer of 5.7 oz carbon cloth on each side for a firewall (not front mounted but rear mounted), and have put nearly 1000 total flights on my e-models with that setup and never a failure of the firewall.
All the mounting problems appear to me associated with front mounting the motors, but that is not how Pletti's are setup.
