Contest - Contest - Contest P1011820

Jacob exempts himself from these contests, so he gets a year's subscription to Air Classics. To allay fears of an inside track, I am excluding Rene from competing so he gets a years' subscription to Air Classics too.

Jacob (bless his heart Smile) will act as arbitrator in any dispute.

I would encourage everyone here to participate

Let's see?
Cox engines with props ----- about 1 ounce each.
The wood ----- heavier than balsa ----- check
Wire ----- yep!
Glue and paint ----- on the heavy side just make sure it doesn't vibrate apart

final weight ----- 28.78 oz without fuel.
