Wow, how sad!!!

Looks like the meltdown has wiped out most of November and all of the Threads through Jan 23rd!! A huge amount of good information has been lost. I have my computer set to backup critical data every night and just once it has saved me -- but once is enough. Of course, I didn't start the daily backups until I had a bad experience with NO backup.

Anyway, Bill you have my phone number and feel free to give me a call anytime. I hope others will repost the kind of information they had originally posted. Maybe just maybe someone has saved this and/or threads and that Sparky can then restore.

Here is the information for running the two Ducted Fans with my U/Tronics Single Channel control.

Please follow the starting sequence given at the bottom of the instruction sheet.

Bill,
Here's my 2 cents.

You are beyond where most of us have experience. I applaud you for your efforts! 
 I think it is a good idea to start where you are at--basically something in the "15-20" size category.
 
So I would just do it! Somewhere on this board I have a thread about my 1/2 A pusher canard plane. Not sure if I will continue with it or not, but I learned a few things (also they were pointed out to me). Certainly was a bizarre first flight!

I have a similar rc ducted fan-a Fantom ---http://www.hobbypeople.net/gallery/107310.asp

It is a hoot to fly, and when I'm in the mood (which is soon--it looks like above 32F on Monday!) it is a lot of fun. Big open maneuvers and the "swoosh" factor can't be underestimated. It is a single fan of course using a 3s2100mAHr battery for energy.

As a prototype, you might consider changing your plan to a single fan. The only reason is to save a few bucks to see whether there are any show stoppers. A two fan setup requires 2 ESC's (mine has a single 30A ESC). I know that what you show looks cooler, but I am a big believer in "small baby steps" when tip-toeing in the dark! If it looks like it might be a success, then I would go for what you want to do.

Anyway that's my take on it. There are a lot of issues---jets aren't known for their square maneuvers for example. However there is a real "cool" factor here.

In one of the lost posts was a tag to another forum.  I remember reading it and looking at the other information.  The thing I remember most was that for 3D RC they want 2 to 1 thrust to weight so you should have plenty of thrust for what you want to do.

Good luck friend,
Clancy

Bill,

You say the all up weight of the model will be 20 OZ.  Is this correct?  2 EDFs and batteries are going to eat up a big chunk of that.

 Sorry Bill, gots big fingers --- meant to hit the 3 for 30 ozs.

 Don't get me side tracked Dennis. That's a heck of an idea though. I put that one in the book, will look into it after this one.

  Looks like I'm runnin into trouble already. Here is the gear I wish to use and its weight.

 From Hobby Lobby  (2)Alpha Fans  ALF5103M 1 oz each ---- (2)Mega Motors mm1675 1.7 ozs each ---- (1)Thunder Power 4s Xtreme V2 3300 mAh  12.4 ozs

 FromCastle Creations  (2)Phoenix 45 ESC's  1 oz each

  If I added right this comes to 19.8 ozs total. Dosen't give me much room for error does it? Does this equipment seem right to you?

I'm really  impressed by your squirrel torture rack (picture #2).

Hey Bill,
Are you familiar with this company. In addition to the EDF unit shown on this page, in the "Propulsion" section, there's a $200 EDF set that produces 4.2 lbs. of thrust! See:   http://www.Ductedfans.com/Hoffman_brushless_Beast_Wild_Beast_Mighty_Might.html
