Thanks for the info guys.  I'll take a look at the 450's and and 50 size gassers.  My next question would electric or gas?  I have a vacant lot next door to me that I keep mowed so I was thinking of an electric.  My only obsticles would be the privacy fences (lol).  Are there any heli flying events around the Houston area.  I used to fly at the Brazoria Cty Modelers Club but therewere never any heli's out there.  Thanks
