I bought the Dx5E for use with a BNF plane; works great. If you are only going to have one plane; there's not a lot of reason to get the Dx6i. I thought I was only going to have the one plane in my fleet that plan didn't last too long!!! Re-binding each time can be done but it's annoying; so I have ordered a Dx6i.

This is what most of the other contributors are alluding; if you stay in it, you'll eventually want something that allows you to store multiple models, and the cost to have both is pretty high compared to the cost of just the higher end unit.

Having said that, I don't think I made a mistake as
1) I can use the DX5e for student box, the DX6i as master, to buddy box my son;
2) We can both fly at the same time when he has progressed
3) The Dx5e can be my back-up in the even the 6 is down for some reason (very unlikely...)
