the fox engine came... and it was great. when i was tuning it... i put it to full thottle and let go a bit of the plane and it would just fly out of my hand. so i am now confident that this plane will hover. the throttle response is fast, this is a great engine. she is ready for the maiden. i'm planning to go out to Chatfield.. and maiden it this Sat if it's not too windy. i will keep you posted on the maiden ( look for a new thread)
