OK first your original question on biplanes Yes there are some very easy to fly biplanes and two examples are the Sig Hog Bipes or the Cunningham Lazy Aces in fact the lazy Ace is virtually the Kadet Senior of the biplane world. Now two prime examples of biplanes to avoid as a first bipe are any version of either the Ultimates or Pitts and their are many others.

As already posted by the fellows all biplanes suffer from excess drag and the throttle/pitch control must be managed as real flight controls and this will be very new to anyone just coming off a trainer. This is an additional skill that must be learned and that's why biplanes are never recommended as a primary trainer.

Now to your second question in your second post as to are there any 3Dish looking airplanes that can work like a trainer and the answer is Yes a few very few but with a caviat or warning. J.Duncker the moderator mentioned a few in his post above. These airplanes are generally .25 to .40 sized and are non scale types and have very fat wings (thick). The one I believe that is near to top of the few is the Sig something extra and yes they actually can be setup and prepared as a basic trainer. Will they fly like a trainer? Certainly not but they can be used as such if and only if you are willing to find a mentor/instructor and to work with him and not go off on your own.

If you are the type who will not work with a mentor and insist on self training then that type of airplane will not live long for you. Its the strong compulsion to have something that looks sexy or like a P-51, Ultimate, B-17, Extra or Cessna and on and on as a first airplane, that is the major reason so many fail and move on.
