Ivan, When we flew U-control the beasts were so overpowered that the airfoil meant very little. Exact airfoils mean a lot in free flight and RC. In UC just about anything flew. If the undercamber disappeared due to ballooning the thing still flew so we were happy. UControl got critical with the Stunting and Carrier Landing events because there the fliers had to have a controllable airplane that would not change its characteristics. For scale or sport flying it did not matter all that much.
Now with RC one wants a well balanced airplane with predictable flying qualities. Especially with WW1 biplanes in the scale events because there one cannot change the proportions of the wings, tail, etc. The more factors that enter into the model the more interesting it becomes. 
At this point in time I do intend to make a RC slow flier for Reginald of his 6 gun Se5-A. I'll keep you guys informed as to my progress.

    Hi Stephen,

    I guess "ballooning" is a relatively new thing to plastic modeling, so it may be seldom seen in plastic kits. I´ve seen this effect in Roden´s kits.
    Regarding stick and tissue flying models, the "old" modelers suggested sticking tissue to each undercambered rib using blasa cement instead of dope because if tissue becomes detached, it will run flat modifying the airfoil.
