Stick Bender

I think aluminum is better for a beginner. I personally broke 3 carbon fiber landing gears trying to learn to fly an Extra 260. (including a graphtech set which are very strong but brittle) The one set of aluminum I used got bent back several times before a dead stick that finally broke the aluminum. I'm doing well enough now that I use mostly carbon. But back then aluminum was best for my skill level.

I hope this info helps you decide.
