This has got to be the best idea ever.

I'm going to put together two arf's. Probably a pair of Uprar .40's.
I'm going to build them exactly the same.
Same engines, props, servos, everything.

Then I'm going to put the same receiver crystal in each of the receivers, so that they'll both respond exactly the same, at the same time, to my transmitter.
Then I can do perfect formation flying with them.

Right?
