I am enjoying all the advanced issues being discussed on this forum, but have a very simple question. I am building a Deluxe Telemaster 40 electric and have noted that the plywood firewall is full of holes, possibly to lighten the structure, and for the optional nose wheel. (I am building a tail dragger.) Lots of bugs and dirt may enter the airplanes interior through these holes. Are they needed for battery cooling, or some other reason, or can I cover them all with a piece of ultra-thin ply or something of the sort. All I anticipate needing in the way of holes is one to allow passage of the motor wires.

This plane is not a thing of beauty to begin with, and that is not its purpose, but the nose is really ugly. Does anyone make or can anyone suggest an upgrade to this area?

Thanks in advance.
