how realistic can "scale" be?
There is no limit as to what you can do to make an R/C model scale. You can have a bomb drop, working landing lights, scale hatches that hide fuel fill and radio switches, sliding canopy, scale retract gear, such as the rotating kind used on Grumman Hellcats, etc, etc. If possible, you should try to get to Toledo, Ohio for the Weak Signals show in April. Some of the scale work you see there is unbelieveable.
