Repectfully, I would personally reword that to say...
If the student relies on the radio for somethings then they never really learn how to TRIM properly. mixes are use to correct trim issues, not pilot issues unless its because the pilot os too lazy trim the plane out right..

Ken is right,,, there are a LOT of lazy pilots out there that never take the time to learn how to mechaincally setup a plane correctly which results in a plane that doesnt fly well regardless of how much mix you put in

BUT>>>

Computer radio mixes can help to make up for inherent trim deficiencies in an airframe. However, If the new pilot ( at the 2nd plane level IMO) learns to adjust the basic mechanical parameters (thrust, cg, lateral balance, properly set throws) to get the plane flying as true as possible and THEN use the radio to mix out that what cannot be trimmed out by having a well setup airframe, they are WAY better off in the long run..... There is no way anyone should need to mix out a trainer, cub, cessna or whatever.. They all do fine for what they are designed to do without using computer mixed trimming....

BUT if you are flying an 3D Ultimate Biplane and you want to take the inherent pull to the canopy that cannot be corrected with any amount of mechanical adjustment without sacrificing other qualities then a computer radio is a priceless tool.
Learning to fly an airplane that flies like crap even after the person trimming has done everything in their power to setup the plane correctly, is not learning to fly properly its just being heardheaded.

I will repeat what I have said before as a comparison.. Who in their right mind would try to drive their car down the road with the front end 6" out of alignment and the car pulling hard to the left just to prove that it makes them a better driver... NOONE. Why should you not use mixing to fix what you cant fix mechanically...



So in short..... the 9C is PERFECT for a beginner if you want a pretty simple radio that you can use for anything you could ever want to fly including a basic trainer,,, to a pattern plane, to 3D planes and complex heli and glider setups... The radio is ridiculously simple to use,, all it takes is sitting with the radio and the manual for about 30minutes to an hour to be able to setup the basic parameters with relaitve ease..
Respectfully, some of the older guys that arent computer saavy do struggle a little with computer radios... But the typical person from 15- 50 have no problems mastering the 9C really quickly.
