so i plan on building a balsa and tissue paper model and i have spare electronics, radios, and plenty of wood to work with, i just need a way to make it able to withstand a wing clip or ryanair slam-on-runway and to make it small enough and slow enough to fly indoors, i plan to make the wingspan 10 inches with a Piper cub-cessna mix look with high wing config, lotta lift, big @$$ wheels, if anyone is into this type of stuff and makes tougher balsa planes, please teach me how to make balsa wood strong enough to withstad a wing clip or ryanair slam-on-runway. thanks for the help if anyone responds with info.
