I will sound extremely harsh and blunt with my next statement, so I will apologize in advance and will leave this thread alone at your request. You do with your money whatever you want, all I can do is provide advise and try to help you along to avoid headaches....

Honestly you sound like a newbie that did a little homework and fell in love with the TRex 500 Flybarless. You seem to lack the experience required to fly that machine. Although not a bad machine to start off with, I will strongly suggest the help of an experienced flier in your area. Only you can find a person that you trust.

Here are a couple of sites to get in contact with some people around your area:

[link]http://www.modelaircraft.org/clubsearch.aspx[/link]

Then after saying all that, I would also suggest that you find out which helicopter is the most popular in your area, and you could get that instead of the TRex 500 FBL. The combined experience of the local pilots in your area will be much more valuable to you than anything that gets typed here or any other forum you visit.

Again, I apologize if your level of experience is higher than what your questions lead me to believe. I cannot see your body language and facial expressions when the question is typed, so I have no clue of your backgorund.

Hope I was of some help.
