Bravo!! [sm=thumbup.gif][sm=thumbup.gif]
I got an Avistar for my return to RC flying after 15 years away from it, and you're going to enjoy the airplane - it has no bad habits, which makes it a great first airplane

(If you haven't already, do a search on RCU for AVISTAR and read what others say - universally positive.
You have probably thought about this, but I suggest your friend fly the airplane until it is set up and trimmed properly, then give you the transmitter with enough altitude so he can rescue it from any "student induced" danger

.
I also suggest he take off and land for the first several flights until you can control the airplane in low passes close to the ground, then you will have the skills to land. Takeoffs are easier than landings, so you should be able to make them sooner
Let us know how it goes!!!
Cheers!
