Glad you started this thread,
jimmilew. I bought the yellow one ("upgraded brushless") a couple of months ago, and knew very little about it; couldn't find much information on the web and the included instruction sheet is almost comically un-helpful. The video was enlightening, I'd thought the plane was a real dog at first, but am trying to both tune up the plane and improve my flying skills. Had no idea about putting the battery up under the wing until I saw the video just now, I enlarged the space underneath and made a new cover. I'm new at this too. Good luck, if you buy one of these, my guess is you'll do OK.
Having said that, I bought a
Hobby Zone Champ prior to getting the Cub, and it's proven to be really good to learn on. It is much smaller, but has a popular following as one can see in the forums. I've flown the Cub 3 times so far, but take the Champ out every chance I get, it's so much fun.
