Hi Ajax. I started learning on a condor. Very basic instruments and no radio. Half way through training I had a good look at the inside of a PA28 ( Cherokee) it was stuffed with instruments and my immediate reaction was how could I possibly get to grips with that lot and fly the aeroplane!
When it came to converting to the PA28, no problems at all. Its just a matter of familiarity. Trust me!
Best wishes and enjoy!
