Do the other Spektrum transmitters (DX6i, DX7, DX8 etc.) only need to be bound once to each plane? That is, once they've been bound to a plane, if I used a different plane, and came back, I wouldn't have to re-bind?
Model Match ( already talked about ) is a VERY nice feature, that prevents you from taking off with your plane misconfigured, or your TX configured for a different model.
Imagine what can ( and will ) happen without it... you go to fly, the plane heads down the runway and lifts off, only to find that the ailerons are reversed... crash...
It is a good idea to go with the best TX you can afford.
A good transmitter will support many different planes and will last you a long time.
A cheaper TX may not last you as long, and you may be wishing for more channels or features, which will cost you in the long run.
Spending a bit more on a good TX, not only gives you an overall cost savings over time, but you'll be working with higher quality more feature rich equipment during the same period....
