forget the cub. your much better off with the apprentice. first of all, the apprentice will fly way better and handle a little breeze unlike the cub which gets bumped around easily. also, the apprentice has much better construction and will survive the given bumps and bruises, unlike the cub's type of foam. the apprentice will also have a huge parts availability at nearly all hobby shop, besides online. the quality of flight, construction and electric components are superior on the apprentice. so don't be cheap over a $100 bucks. you get what you pay for including headaches. ive been an instructor for many years and have used both aircraft may times. listen to what im telling you and skip the cub.
the apprentice wing is easily removed for transport too! you can buy your batteries at hobbypartz.com look for a 30c 3s 3800mah , great prices and ships from CA. you only need two packs. you can add whatever decails you'd like for visibility to any plane
