Please glue the wing halves together with 30 min epoxy, don't depend on the small joiner straps and trim tape. The Avistar is my favorite to help students to learn; you can fly in more wind than the flat bottom versions without feeding in so much down to keep it from ballooning during landing.
I don't recall if the ARF has the same vertical stab bolt on as the RTF, but you need to epoxy in if it is. Too many times the nuts will vibrate loose letting the horizontal stab shift and or the whole tail group breaking off.
After break-in, change to a new glow plug. Small metal sludge will coat and burn onto the glow plug coil and cause hard starting and deadsticks. You'll know it's time when you remove the ni-starter and the engine suddenly drops rpm.
