the Piece-O-Cake is a two channel motor glider. You hand launch it and the engine is only supposed to run for a minute or two to get you to altitude then shut off. Then you you hunt for thermals. I have flown mine a few times for around 30 min's.
Spruce wood will be heavy and hard compared to balsa. Spruce will generally be a white wood like a 2X4 only hopefully a lot smaller. Balsa will generally be a more tan color. Sometimes on the plans there is a picture of the different end grains of the woods.
I will see if I still have the manual down in the shop.
hope this helped

Thank you for the information. I was curious why the engine specs only said that it would provide me 5 minutes of run time. So it is supposed to glide after the engine cuts out? So I am guessing this glider is ment for slightly windy conditions?
