over 15 pounds as an unpowered sailplane (I have built two noses for it).  It has completed almost 50 flights presently, with about 10 as a motorized sailplane and the remainder launched from a winch.  I am quite pleased with the whole project.

Mini-Fan 480 and a HP 200-20-60 motor or the Aveox 1114/4Y on 8-10 1250mAh cells.

Henschel Hs132 Article

I read with great interest the article called "LET'S TRY AN EDF." in the July Ampeer. Why? Because I am the one that designed the Hs132 that is described. I am very surprised that the model became tail heavy. He wrote that the fan is located behind the CG. This must be a misprint. The fan and motor are placed exactly on the CG so you can test different fan units and motors without a CG change. If you look at the picture you can see the white spinner from the impeller, and it is located on the wing where the CG should be. My model with 7 cells gets the right balance if the front of the battery is lined up with the rear of the silver painted cockpit (see picture). He must have had very bad luck with heavy wood when he built his model.
Anyway, the model was design to be a easy to build and fly EDF model, and at the time I design the model (several years ago) the only electric fan unit on the market was the Morley Jet Elec.
I fly my model with 8 Sanyo 1700SCRC or RC2000. The motor I have found best with this fan is the Kyosho Mega, 2x20 windings with the timing fully advanced. Static test with this combinations gave 400g(14oz) of thrust (28A). This model flies OK with this combination. With no wind the climb is not great, but it is fun to fly and it looks great in the air.
At a Jet meeting a month ago I was the only model in the air the last day of the meeting. It was to windy to fly for them!
I have talked to other builders of this model that have used the Mini-Fan 480 with a 480 race and lighter cells with great success. A very good setup would be the

I'm building a 48", high-wing rubber powered model that I intend to convert to Electric.  I envision a REALLY LIGHT WEIGHT plane using  rudder only with the smallest receiver and servo I can find.  For power I intend to use the rubber prop and about 8" of rubber motor mostly for a drive shaft/universal joint kinda thing.  Now comes the really wild idea...I have removed the motor and gear reduction drive from a Polaroid camera.  This sounds hokey...but this is a really powerful motor along with the gear reduction drive.  The 6v batteries that are available in any spent Polaroid film pack should give a nice flight duration and are very light weight.  I might even use them for Rx and servo power....though small button cells would do nicely here.  I picture a really slo flyer with a lot of time for controlling.   Just a word about me...I started RC in early 60's flew CW and escapements, pulse, reeds and finally proportional 10 channel.  Most successful was a Logitrol/KAOS stunt plane.  As you can see I have some hours at the stick.  I am now retired and have the urge to get back into flying, but I don't have any desire to carry gas cans, starters, flying boxes oily rag cleanup etc, etc,etc.  Just pop the plane out of the trunk and FLY. 
I'm also building a 30" Ryan ST that will be quite small for what I had in mind but it was my first experience with laser cut kit and CA glue...What a joy to build.
P.S.  Why don't I hear more about Lithium Rechargable continue
