RE: Do fly it or not?
The manual has sections for a number of JR radios.
I'm guessing, but you've got a 6 channel receiver don't you? And you're using Section 19 in the builder's manual to setup the airplane, right?
When you're setting up a new aircraft, make sure you reset the radio's programming for that airplane in the radio back to the factory defaults before you start plugging everything in.
