First a little background. I have been flying electric RC for about 3 years. From fast to slow, foam to balsa, but blimps have held my imagination. I would like to build and fly a small RC blimp.

Our electric club flys in spaces as small as a basketball courts and as large a a professional football dome. Ideally I'd like something that I could fly in my 3 car garage with 12 foot ceilings.

I am thinking of something in the 4-5' range with two direct drive GWS IPS motors a 2 cell Li-poly pack ~ 350 mah, FMA M5 reciever, and GWS pico servos. I was thinking of designing something with a pair of servos to provide vectored thrust (one providing up/down, one left right). Is this stuff too heavy for the size I'm looking at?

So, just how far off my rocker am I? Can someone suggest a good "kit" or supplier of blimp bags?

At this point any help would be appreciated.

I am building a blimp myself and would like to point you to:

NYblimp (www.nyblimp.com)

My Blimp thread in the micro/indoor forum (http://www.rcgroups.com/forums/showthread.php?s=&threadid=151681)

one thing I HIGHLY reccomend is e-mailing the person at NYblimp, he helped me a TON with building my blimp!

On my blimp, as I wanted to have maneuverability with zero airspeed, I modified hs-300 servos into little forward/reverse 1amp speed controls using the directions from the nyblimp site. those "ESCs" power two edp-20 motors running off of a 5cell 300mah nimh pack. pics are linked in the micro thread posted above. Any other questions?

I built a really inexpensive blimp out of a X-mas Santa balloon that I got from Safeway, and ZipZap (one of those little remote control cars that can be bought at Radio Shack or Walmart). I gutted the little car of its electronics, and replaced the "turning coil" with another motor from a pager.I then placed the motors on a small square of balsa at right angles, and angled them slightly downwards as well. The battery was placed in the center of the balsa, along with the "brain" of the car and all of this was glued to the bottom of the Santa head. I carved 2 small props out of balsa, and forced them onto the motor shafts. To make the airship float almost weightlessly, I added a bit of clay at a time to the "cabin" of the blimp until it just hung in the air anywhere I placed it. So, one motor could push slightly up and right, while the other motor could push up and forward, or the first could pull down and slightly left...
