Rich,

I am releasing two addendums to the plans on Wednesday, November 10. One is for attaching a glow engine and the other is for landing gear.

You can contact me direct (see my profile on RC Groups or contact me through http://www.flyingwing.net) for more details.

Best regards,

Jeff

Ho 229 Build Pictures


Hinging the port elevon is complete. I am laminating the port EDF mount. Preparing to install center section sheeting and rib caps. With both servos and EDFs installed, weight is 2 lbs 4 oz. Still on target for a 3.0 - 3.5 lb total build.

Jeff,

It's looking great! What is that in the last picture you posted? Is it just some weight on your lamination, or something else?

Thanks!

Ho229


In looking at the fan installation you have it really looks like your fans are way too big for the wing as well as being too far to the rear. I hope I am wrong but I think for that fan size your airframe needs to be in at least 1/8 scale or bigger for those fans.



Let me know what you think,

EngineerW,

I appreciate your concern over the size and placement of the fans.

The Ho 229 I am building is about 1/11 scale at 72" wingspan. A 1/8th scale Ho 229 would be around 82"

The Junkers 004 turbojet had a diameter of 32". At 1/11 scale the diameter should be around 2.9 inches. At 1/8 scale the engine diameter should be around 4". The EDF's in the Ho 229 I am building have a 3" diameter.

The tips of the exhaust cones on the EDF's are right where they would be on the full scale H0 229.

Thanks so much for your feedback. Much appreciated.


Jeff

Thanks for that explanation Jeff, You clearly have done your homework! I was wondering. Your web site said that you are doing the V3 is that true? I really liked the V2 better because of the flush inlets.

Anyway, I can't wait to see it fly!

Thanks a bunch for the feedback as I really do appreciate it. It is always good to hear constructive criticism as it allows me to see the project through someone else's eyes.

I am in the final few days of sheeting and sanding. Sometime this weekend, probably late Sunday evening, I will begin covering the aircraft. We might (and I do stress MIGHT) be ready for a maiden glide in 9 days.

Here's the latest and greatest pictures....

Jeff

P.S. The round object in the pictures is the intake for the EDF. It's rough and right off of the form.

I get all kinds of email. Yesterday I received a picture of a man pointing at a drawing of a UFO he spotted in 1947. The author of the email said, "This sure looks like a Horten to me. Maybe the US was flying these in secret."

EngineerW asked about the V3's round inlets. I thought about creating a V2 with the flush inlets, then I found these beautiful pictures of the V3 on http://www.luft46.com. Here's just one of the pictures:




Drawing credits to Mario Merino.

I was a bit concerned about making sure that there is a 3" diameter opening going from the intake on the leading edge to the EDF. I could not create a flush opening and maintain the 3" duct. Luckily, the V3 has a round intake and it allows me to maintain the 3" opening.

I predict your Ho-229 will be far easier to balance if you moved the fan units forward.

I see your point in wanting the motor fairings to protrude from the rear. But, the better solution would be to have some fake cones for ground display only.

With the increased use of lighter Li-po batteries, I feel that models should be planned and arranged to minimize the need to add nose ballast.

Nice job, overall. I also liked your N9M. I have a small N9M project of my own in the works.
