RE: Futaba 8UAP TX how good is it?
Well the diffs between the Super and non super versions are as follow:
Airplane mode: The super has 7 prog mixes, vs 5, and these two extras are 5 point mixes.
better trainer function ( don't need to have the slave transmitter fully programmed) on the Super version (this applies to all modes)
Heli mode: CCPM mix added in the Super version, as well as gyro function ( both can be programmed in the non-super version, with a little help from the futaba website.... they describe how to manually program those mixes)....
Sailplane mode: No clue, never used it.
I have a Non super futaba 8UAP since 1997 and it's still an awesome radio. I recently got a 9C super radio, but only because I wanted two transmitter to control over a dozen planes.... would be a shame to be grounded because a transmitter needs repairs.
