E-FliteRC Airplane Commander MPD 1.4m BNF Basic Transmitter Battery and Charger Not Included with AS3X and Safe Select EFL14850

What is it made of. Wood built up or Foam?

Do the wheel covers render this model inappropriate for flying on a grass airfield? Looks like the plane would tip forward as soon as it hits grass

Can I swap out the receiver to fly with a Futaba radio?

Is there tape holding the canopy on when you unpack the package?
