I appreciate each one of the previous posts.[sm=thumbs_up.gif]

We have deviated a little to discuss pilots' skills and advisers' wisdom and curriculum; however, those are the thinking softwares behing the radio sticks, and I would like to return the thread's focus to the hardware on the other end: the model airplane.

For example, reading about propellers tonight, I have found this statement that again, mentions what for any beginner sounds like vague and unclear concepts (highlighted in red):

"Trainers and many lower-performance sport models are unable to take full advantage of the performance increase that CF propellers provide .......Hollow CF propellers are light, allowing for the fastest engine acceleration possible. They feature excellent performance across the entire aerobatic spectrum."

Other examples:

"IMAC and Pattern are two different but similar AMA events, both aerobatic. IMAC is flown with scale aerobats and Pattern is flown with unlimited design requirements except for max weight (5 kilos) and size (must fit inside a two meter box). F3A is a type of schedule flown in Pattern, more specifically the top International schedule flown at World competitions."

"I build and fly the old school pattern planes because they make great sport planes too. Today's pattern planes are much more advanced but you can fly the basics with planes like the Kaos."

I would like to see this thread developing in a direction where concepts like those (types, specifics, limits of different models) are explained to beginners by experienced RC pilots.
