Title: To those who have experience with Electric Ducted Fan models
Post by: John Cralley on February 06, 2009, 09:17:14 AM

I suspect that many forum members also fly RC and some, no doubt, have a great deal of experience building and flying electric ducted fan powered models.

Bill Gruby is planning on experimenting with EDF power for a modified control line Ringmaster. He had some useful information in a thread which was lost in the recent server crash and he is hoping to regain some of that information as well as gather new advice for his project. If you do not follow the "Gettin All AMP'ed Up" forum here in Stunt Hanger, you may not be aware of this project and Bill's need for help choosing a workable combination of motor/fan/battery/ESC to power this model. I urge those with EDF experience to contribute your suggestions in this thread:

Thanks in advance.

Several years ago John Grigsby and I built a modified Twister
with a K & B .21/Kress Jets ducted fan setup; the Twist-O-Jet.
The plane had very little power, but it was a hoot to fly. Starting
it up and hearing the sound of 20,000+ rpms was the best part.

Later, Steve

Another site to think about is:    wattflyer dot com  .  They are hard on us that still fly nitro and gas.  DOC Holliday

Mr. Cralley:

Just to throw in an item, I would like to first be a disclaimer. I own no stock in Flying Models magazine, however it is by far my favorite one. I have been a subscriber beyond my memory.

For your request, may I say that the March 2009 issue of FM has an article that should wow any person with any interest in electrics, ducted fans, etc., etc. The building article is truly a work of art including foam and wood structure. The machine is, as presented, RC. However as almost any model airplane, changing an RC to CL or vice versa is no big deal. I strongly reccommend anyone with any real modeling interest check this out.

For me I have no interest in electric. Another week and I turn 73 with modeling junk dated back into the late '40s. Still this FM article is fascinating. 40" wingspan, 67" long, B-58 Hustler, Composite of sheet foam and balsa.

FYI, I am now trying to get back into some OT Stunt after 35 years away from CL. Man, it ain't easy  %^@

Horrace, Thanks for the heads up on the Flying Models article. I do not subscribe to FM and would most likely have missed it.

As to returning to Stunt, I'm in the same boat except that I am 76 and my reaction times are not that great. Still I have fun just flying.
