Note that he said "huge 4-bladed prop on the front" in the third sentence, not dinky 4-bladed prop. Like someone already mentioned above, you need to read the posts a bit closer.

The original question in Post #1 was "Why do you folks not use Four blade props on your Mustangs?"

My answer in Post #3 was "model airplane engines do not have the power to swing scale diameter 4-blade props."

My answer still stands. Scale diameter means 20" on a 1/7th scale Mustang, not 15" or 16".

By the way, here is a picture of my Corsair with a "flying" Hamilton Standard 3-blade prop on it:



At least the prop looks like a scale prop.
