Go to YouTube and type in B-29 model. There is a HUGE one out there as well as one that launches an actual rocket propelled X-1 controlled by a separate pilot.
Actually, YouTube has an amazing number of model airplane and Model Helicopter videos.

The larger one is so big that they said the four blade thing would not work and they had to go with two blades. It may be why this B-50 has two bladed props as well.
