What do you want it for? ....
That's a good question. I like precision aerobatics and sport flying. Not a 3D fan at all. So, the more precise is the airplane, the better.
With all these recommendations, it is going to be hard to choose from. If at first sight I thought one biple was enough, I am consider more than one.
I do not worry about the building difficulty. I know it helps to have it sooner in the air, but I have learned to be patient in my buildings. I build all of my planes and I improve my building skills in every model.
So, let's review if I am catching this properly...
1. GP Skybolt is kind a most to have. Good looks and precision.
2. Ultimate's are good at aerobatics.
3. WW1 or pre WW2 because are classic.
4. Sig Hog recommended because it's good for first bipe.
5. ....any more....
