what do i need to know about bipe wings?
It all matters how you want to fly, by the look of your planes, you might want to stick with incedence of a Aeromaster or Pheaton 90. There are a lot of posts on these planes.
A Ultitmate is set 0°,0°,0° and is the truest flying. I would pick a 25% Edge or similar plane at this point. They can be flown gentle or unlimited, but do what you want. If you cannot build very lite, you will be dissapointed with any choice.
I started out wanting a large P-38, after 9 years, I'm still not ready and am just at 35% aerobatic planes, go figure that I wasted a lot of time with small planes. 73" and up wing spans planes are definately better flying and will improve your skill expodentially
My other suggestion would be a Sig 4 Star 120 with a G38 or a US 41. This is a great step with a easy flying plane that makes you grin everytime you fly.
If a air molucule is like a tennis ball to a full size, then the air is like a over filled basket ball at 60" wing span. The larger the plane, the closer to the tennis ball it is and the better flying the plane is.
Just remember to build lite!!!!!!!!!!!!!!!!!!!!!!!!!
