Have Kit but not manual or other instructions. I am interested in any information that any one can provide concern assemblying the model, batteries, motor, prop, CG etc. This a 2 meter glider.

To HLC, I checked the Airtronics website but couldn't find this glider listed. A few general observations; When a manufacturer lists a motor as "550" it's usually what we (now) call a Speed 600 which would be a pretty good replacement. That is a fairly large brushed motor, easily available. Without gearing it would turn a 7 x4 or 8 x 4 prop ( folding prop for a glider) and likely use 7 or 8 cell NiHm or NiCads, mAh anywhere between 1100 to 2000, depending on how long you intend to run the motor. The motor will cost about $ 20.00 and the folding prop about $ 15.00. You will also need a brushed ESC, at least 25-30 amp, figure $ 40.00. A decent brushless upgrade would be anywhere between $ 60.00 to $ 100.00 for the motor (outrunner), a brushlees ESC about $ 60.00 to $ 75.00 and the same prop.
As far as building, if you don't have the directions I would suggest you try to get in touch with an experienced glider or e-glider flyer in your area. Maybe a trip to the local flying field will help or a hobby shop employee might be able to hook you up. I know this isn't much help, maybe more readers will pitch in! If you have more questions, feel free to PM me or post here. Good Luck!

I have an Airtronics Eclipse kit it is a 2 meter electric with the same 550 motor with the folding Master airscrew prop, I have not started the kit yet, but do not hesitate to ask me assembly questions. I bet both kits are very similar in construction. I can email or fax the manual to you, it has many pictures, for such things as dihedral, etc, that is easy to work out, etc.
I will be setting rid of the 550e motor and gearbox (550 is about the same as a 600 speed), I have a geared Astro 05 FAI, and a 50 amp Electrify ESC that will be used with Lipo's. Thanks, Dan

The airplane you are asking about was state of the art in the late 80's and early 90's but is out dated by todays standards. But don't be concerned as it still is a fine sport plane.

The Falcon 550E was designed to use an Astro Cobalt 05. It was a high performance sailplane in its time. It would be awesome with a modern brushless motor. I have seen a couple powered by Aveox motors. Aveox was about the only brushless available when the Falcon was still being produced. I have seen a couple of examples at various flea markets and swap shops and have been tempted to add one to my hanger.

Finding information on a plane that has been out of production for a while can be a challenge. Posting your need on a for sale/wanted forum may provide the results you need. Might cost you a few dollars but it would be well worth it. The Falcon was a beautiful flyer.

Hi thermalfish,
Was wondering if you still have the .pdf file for the build instructions for the airtronics eclipse. I have the large blueprint but lost the instruction booklet. If you have, is it possible to sent to:
home: 408-238-1753
work: 650-318-4572
fax: 650-318-4601
I'm in the process of building but want to avoid mistakes etc.
Any insight you have on building is appreciated!!
Many Tx
