Rubber band help !
I have a 24 inch spitfire balsa model that is rubber band powerd. It can with fai tan 2 contest rubber band and I broke it beyond repairable. My hobby shop sells guillows rubber band which is thicker then the the tan rubber and has a white color. How will the guillows rubber band affect the flight of my airplane. How can I lubricate my rubber band for a longer flight, will Vaseline or Castro oil work?
