Default Bell-Imel group plans

Hello I wondered if any of you that have experience with the Bell-Imel groups 82" wing span GO-229 model would by anychance know if I might be able to fit the Schubeler DS-94 E D F into this scale. Or if i will have to custom scale up these plans. I would prefer not to but I have these fans available to me at very low cost and i would love to make them fit. They are 120mm fans and i beleive the outside diameter of the fan housing is 124 mm If anyone has any information to offer me before i purchase these plans it would be much appreciated.

If you are using 120 mm EDF, scale would be 1/5 , about 132" wing span. 82" is perfect to 90mm EDF. But you may open the inlet more than scale, then it will work also with 120 mm Schuebeler's

Hi Heiner,
Sorry to dig up an old thread, I've just read this and your HO229 V3 is awesome!
I wanted to know if your friend is selling the kits yet? I would be interested in the same V3 as yours, But also possibly a 1/5 with retracts.
Could you PM me with the info?

Thanks
Aaron

Looks like a nice flyer. The Hortens, Lippisches, and Gothas are starting to interest me, as the light wing load puts you in a whole new territory.
Listening to the beginning of the video, a truck starts out in first gear and then shifts to second, in perfect sync with the Horten's takeoff roll. For a minute there, I was thinking what's he got in there?

I'm admittedly unknowledeable about flying wings, and have always worried about having success with a design like this. Since Getting 3 jets to fly on the EDF30 fans, I've really been interested in an EDF30 Gotha or Horten design with the fans. The 30mm fans fly nice in a 22" heavy 262. Would be excellent in a wing, to forego the additional airframe weight.

Heiner, if you remember, you are one of the first people to respond years back when I built my first 262 scratchbuild.

Default absolutely stunning...

what a gorgeous aircraft. amazing to think its design is 60 years old.
it reminds me of a manta ray, the ones i've seen while diving in mexico.

your is much faster though.

congrats on a magnificent plane.

I was watching NatGeo the other night, and they had a show on the Ho-229. The Northrop guys built up a replica and did stealth testing to see how stealthy it really was (it was not a flying model). IIRC, the show said the only flying 229's were done by the Horton Bros, and one of their test pilots was killed when he lost an engine and crashed.

One of the originals is still in military storage near DC, but it is not flyable.

which is kinda weird me thinks since the diam is so different.

however the alfa at 20A is at 50k rpm where the mini around 27k.

so what is power to weight estimate and wing loading?

am i making this too difficult?if so, let me know and ill just go for the minifan setup.

Cheers,

Tim
Tim , why don't you try Tahmazo 55mm EDF ,thrust of 520 grams at 20.1amps,
and 480grams with the 3.7KV rhino motors (17-18amps)

http://www.tahmazo.com/products/catalogue/75/160

Price wise is comparable to Alpha fan and more hardy from my local store.

Cheers

Default Some things never change.

Took 60 years for Northrop to admit the WW II Germans invented our B2 bomber.

The reason for the secrecy is to hide ALL the engineering costs that they charged to the USA.

Northrop could not fly their wings UNTIL computers were available ???

Tell that to the Horten brothers who dogfighted the ME 262 in mock combat. & won.

Love war & politics.

British Avro Vulcan bomber when fighters need their butts kicked.

Few tailed planes can ever come close to flying wings in real life.

Hallo Herr Heiner !
Ich habe mit grossem Interesse IHR Horten HO-229 Projekt bestaunt !!
Wunderbar!
Sie schrieben das Sie das Projekt von einem Herren übernahmen der auch den Design verändern kann.
"I bought the Ho-229 from an older RC-pilot, who caught a balsa alergy. He is able to calculate those Hortens at the computer to scale you want. Minifan, Midifan or even turbine. If you build them, according to the plans, they fly very well. If you are interested in drawings I can contact him for you. (I think he speaks no English) . Next winter I want to build a Horten 229 for 2 x 90mm EDF......."

Können Sie mir BITTE den Namen und die Kontakt Adresse des Herren übersenden.

Ich möchte die Ho-229 als 1:32 Model bauen.

Meine Tewlefon Nummer ist 07032-994090 und meine email lautet
GKCherry1@t-online.de

Funny - yesterday watched the National Geographic programme on the Horten 229 : "Hitlers Stealth Fighter" and the 1:1 scale model built by Grumman in USA to test it's stealth capability ~ 60 years later ...

Amazing ... thinking maybe a nice couple of 50mm EDF's would do nicely ........

And I just realised that www.amtjets.com (gas-turbines, Bennie van de Goor) is just a stone throw away from www.jepe.org (EDF planes, Jean-Paul Schlösser) , only 5km.





www.rbckits.com (e-planes & -boats, Rob Bulk) is a bit further away, 125km.

Click pictures for more EDF-kits


(here ends the commercial for Dutch e-flight manufacturers )
