If you have a LHS check them out.. A lot of them will match prices
if you ask them about it.. I used Tower hobbies(Click on ad above)
since my LHS is 100 miles away.. Fellow club members...

I just picked up a OS 46FX from ebay for $85.. I've "yet" to have a
problem on ebay.. But I do email seller before bidding and get their
phone number and call them.. If they won't give you there number
forget it.. But you have to be Careful... A choice only you can make..

Your Avistar will have good power with the bearing 46.. But don't get
to carried away with hi speed maneuvers.. easy to do with more power
And planes like to fly in there flight envelope, Though the Avistar with
take a lot.. Good luck and have fun!
