I'll pretend I just didn't read that.
The TX is the issue, not the RX. You can fly a champ 1/2 mile away (beyond visual range) with a DX6i, DX7 or DX8.
Used DX6i's are going for $100 and I bought my brand new DX8 for <$185 Shipped to my door after I sold off the $200 in Extras that came with it (which took 1 day)
Crashing 1 plane because you were trying to use a Crappy, cheap TX on multiple planes practically pays for the upgrade to a real TX with model memory.
A REAL TX with Expo and dual rates makes planes that are unflyable, flyable and makes flying anything beyond a Champ so much easier. The Model Memory is just a bonus.
