felix i think its a good choice for your first digital radio eather one will do fine i own both the t6xa will do heli's if you decide further down the road to do so for an extra $20.00, i use both and find them very easy to program and use.EXPO is used for taking some of the over stick handling of a plane..... ive been flying some of my models with about 20% expo in them so you dont over steer it... it sofens te throws...... it will do all you need to get started,and the price is very reasonable $189.00 for the 6exa and $200.00 for the t6xa..... ive used it on a buddy box sorry guys i never noticed a diffrence it worked fine for me
