Have you flown biplanes??

Kyosho tiger moth will teach you basics and you can use your current engine however if you are good, jump strait to CG Ultimate 10-300 ARF or kit, 90 2-s or 120 4-s; any extra in that engine range will do as well!.
Do your best not to jump to 1/4 scale before trying 1/5 !!
you will save money and frustration!!
