Hey there SirCole, I've tried most of the planes talked about so far and also started out with the HZ Super Cub. My recommendation would be:
1. ST Model J3 Cub - 4 channel aileron high wing and very scale. This looks great in the air, flys like a dream, is made of tough foam, is cheap ($140 here in Oz) and lands like a dream with a sprung under carriage. This is still one of my favourites and will often come down to the park with some of my other faster aircraft like the PZ Spitfire, PZ Trojan and e-Flite Sukhoi.
2. The ParkZone Trojan is also a great flyer but it is a fair bit faster than the cub.
3. Get a new transmitter lime the DX6i if you don't already have one.
Hope this helps.
