<p>If you haven&#8217;t seen/heard about it yet.  LiPo batteries can be dangerous, <a href="http://www.youtube.com/results?search_query=lipo+fire&amp;search=Search">check it out</a>.  It is very rare that a lipo would ignite under normal use.  It would take charging it at a higher rate than recommended (typically 1C) or a internal short.  People have had serious property damage, <a href="http://www.rcgroups.com/forums/showthread.php?t=209187">here</a> is a list of what causes the fire and what is damaged. They make commercial battery bunkers, some people use cinder blocks and bags of sand.  I have also seen ammo cans used, but I could not find them locally and I didn&#8217;t want to pay for shipping.  I found a honeywell steel lockbox at WalMart for $10, that is pretty stout.  I don&#8217;t have the desire to test it (yet), but I think is should hold just fine.  Also to help suppress any fire that could arise, I put a Pyrex pan over the battery.  I did buy one of those LiPo charging bags, but it is a pain to open and close every time I want to charge a battery.  I have it lining the bottom of the box.  it is definitely not necessary, but since I have it, why not.  The way I see it, all this effort is the cheapest fire insurance available.</p>

			<content:encoded><![CDATA[<p>I have always been a fan of radio control; cars, robots, computers now planes.  As a child I had several RC Cars that were a bunch of fun.  At the time airplanes were too expensive and the technology<span id="more-3"></span> was not all that great. I had left RC altogether for the past 10 years or so.</p>
<p>Recently my Dad sent me an AirHogs Aero Ace and boy I am glad he did.  They are a ton of fun.  You can get them at WalMart or Target for $30.  Without a doubt the best toy for the price.  They have a 2-axis controler for throttle and lef-right.  There are two small motors setup in a push configuration.  The throttle controls the prop speed and the left-right governs the speed to allow it to pitch side to side.  They fly great and take a lot of abuse.  Here are some pictures:<br />

</highslide></center>As you can see it can take some abuse.  The plane itself charges from the 4 AA batteries in the transmitter.  It is an amazing use of technology.  More to follow.</p>
