I really like the JMB PC21
When I can’t sleep I just go into the basement and look at it ... it’s just a pretty airframe IMHO

If I ever got an A-10 it would likely be the Mibo Jets
“Go big or Go Home” mentality !

Regarding the foamy, I’d check to see if Amir at HAB.se offers an install kit for turbine conversion
Those are available for other airframes and are very nice to work with.
