I have lots of electric models, but all lightweights, for bigger models you need big motors, big esc and big batteries and the cost of which would buy you easily a petrol engine which cost nothing to run, I cant see the point other than no fuel to carry.
You just have to have noise, smells and smoke for scale models.

It would not be practical to remove the wings everytime you have to change batteries, you either have to install the batteries in a fire safe charge bag and charge them on board or make a removable hatch at the front cockpit which would be the only practical place on this model
