You'll probably know when you're ready to land without asking. If your instructor hasn't offered maybe he knows you're not.

Slide something in with a low wing and in tail-dragger configuration with a higher wing loading before you try a war bird. A Sportster or a Uproar maybe? Warbirds are unforgiving of hard landings with the relatively weak and scale landing gear or when you mistakenly attempt too slow of a landing and stall at a low altitude. Crunch.

We have lost the concept of "low wing trainers" and "stunt trainers" and think of only one type of model when we hear the word "trainer" now. R/C used to be a progression. Simulators help, but the real world is still different.
