Well, I'm no pro yet but I'll try to explain it the best I can
But he did stay at a Holiday Inn Express last night.

One thing to remember is a Telemaster has a airfoiled tail section so that translates to the tail lifting very quickly on takeoff and really really slow landings. So you need a less pitch more diameter prop. We have a guy where I fly at with one of these. He first had a 6 pitch prop and in a head wind it was nearly impossible to get it to land as it simply just did not want to stop flying. You literally had to kill the engine.
We finally got him to change to a 5 pitch prop and it really did make all the difference in the world. So as was already mentioned, keep the diameter up and the pitch low
If the engine is new then a 12X5 APC prop. If the engine is already broken in then a 13X5 APC prop would be just about right for that airframe. Telemasters do not like speed. They can take it but they need tons of trim when flown fast. They also make great tow planes when done being used as a trainer and if you convert it to a taildragger then you have a whole new plane
