It seems some like a transformer, some batteries. I bring this up as a new thread for benefit of us newbies, mainly not to garble another thread when someone does a search. As a long time large scale RC airplane (and 'N' scaler) guy, I'm pretty familiar with remote control, nicads and lipo's (lithium). I see advantages in both-except for the pretty long recharge times. Would someone please outline/describe..and/or pics of how to run remote control w/battery power. I'm trying to understand here voltages, controllers, servos etc. Is there a preponderance of one system over the other for, specifically, outdoor use? Thanks guys, you folks are a helpful lot!
