What do you mean by prop control? The Decathlon has a fixed pitch prop. Do you mean the throttle?
I was referring to the Super Decathlon with the 180hp lycoming and constant speed prop.
By the way, I agree with everything that Ramjet555 says.
And even with around hundred back seat hours instructing in the Super D, I most of all have a huge respect for the lack of forward visibility during approach and landing. Especially at slow speeds where the wing profile of the Decathlon gives you a very high pitch attitude compared to other light aircrafts.
I know of at least one accident where this was the contributing factor.
