The Electricub is a great kit to build, but not sure if it's the first one you want to try and fly with. As Buzz has said the kit comes with a outdated brushed motor. For a first "getting back into it" build it would be a good one. Just do some research in these forums as to what motor upgrades are good.

I used a Turnigy TR 35-48-B 900kv brushless outrunner, By Hobby King. I use 3 cell 3300mah batteries and a Thunderbird 54 ESC. The plane flies very well.

But if you have never actually started flying you might want to start with a trainer. Even though some folks think a cub is a trainer, it can be a handful compared to actual trainers.

A great trainer is a E-Flite Apprentice if you decide to get something ready to fly to start with.

Here is my Cub which is a good kit.
