RE: Out of trim trainer
Teaching is not an easy task. You're not just teaching someone how to fly straight-n-level, a level turn or a loop, you are also teaching the newbie pre-flight setup, engine tuning and ground radio setup / trimming. If the instructor is not familiar with how to ground prep an electric trainer - don't give 'em a bad rap, take responsibility for him and help do the ground prep. If the instructor knows the Spektrum DX7 but doesn't have a clue about the programming of a Futaba radio, take responsibility for radio setup and trimming. Team work will result in a very successful training experience for the new flyer. They will be able to identify the go-to guys for their particular equipment.
On plane selection, fly what puts a smile on your face as long as it's within your flying skills. What puts a smile on my face might well turn you off. And, what you fly may put me off. That's cool. Diversity is a good thing, a very good thing.
