RE: What type of Propeller?
Hi!
Just forget the P-51 Mustang...at least for a year or two and at least 2-3 simpler airplanes.
Remember ...you will crash...this despite how much help you get or how old you are.
Get a high winged trainer first ...and learn on then a low winged sport model.
Kyosho Calmato is a good trainer airplane.
