I just got back into RC after more than a Decade off from my origional aborted start in the hobby . I am also builidng a Dazzler Which is a now discontinued plane which I had origionally built @ 13 yrs ago when I first started. I put a 46 LAin that back then and a guy at theRC feild I went toflew it well. That was before simulators - I never learned to fly - i crashed my trainer(s)- gave up in frustration and sold the Dazzler.

. I played witha simulator for4 Months,did some Heli flying, and Now I've been flying Fixed wing Electrics for just under 3months-Now thanks to Simulators I'm reasonably competant - Doing beginner 3D with my Foam Yak 54 CZ......
