RE: P-47D eflight
The 450's aluminum shaft is quite soft
==============
Not sure I follow this one? The 450 outrunner uses a 3.2mm hardened steel shaft that is very durable (and replaceable).
FWIW, no hot glue is used on the P-47 at the factory. It is a different type of glue. Room for improvement has been noted in motor mount and LG gluing, and future production should be improved.
