RE: Horten Ho 229 Build
Almost finished with the Ho 229. I am attaching the elevons this evening and I will balance the aircraft tomorrow afternoon.
The weather does not look good tomorrow with wind gusts up to 35 MPH. Monday looks much better. We'll play it by ear tomorrow. Video and still pictures will be up shortly after we get back from the field....if it flies.
More updates tomorrow. Pictures of the completed H0 229 will be posted in the next 24 hours.
Best regards,
Jeff

RE: Horten Ho 229 Build
The Ho 229 successfully completed 12 non-powered test flights this afternoon. Winds were out of the west at 16 MPH, gusting to 22. I have uploaded a low resolution video of a few of the flights. You can click on the link below to view the video.

The next phase of flight testing begins tomorrow with the installation of the EDFs.

RE: Horten Ho 229 Build
We are preparing for powered flight testing this weekend, weather permitting. While the fiberglass nacelles dry, I have been working on the plans and the Builder's Notes. The most effort is going into designing the nacelles so that they are easy to build and can either be made out of balsa wood or fiberglass. In one design, using fiberglass, a 3" PVC pipe can be used as the mold. In another design, the nacelles are built up using an internal balsa structure with external sheeting. I am detailing both methods so the builder can choose either one or use their own method.
Best regards,
Jeff

RE: Horten Ho 229 Build
Almost finished. I am sanding the nacelles today and plan to fly tomorrow, weather permitting.
We released the foam cutter package for the 20 foot Northrop N9M yesterday afternoon. This flying wing is 1/3 the size of the full scale Northrop N9M.
Best regards to all,

RE: Horten Ho 229 Build
The two 3" GWS engines do the job on the 72" Horten 229. I am getting 6 minutes of full throttle burn time on a single 2400 mAh NiCad pack. With throttle management, I can get 10 - 12 minutes of flight time.
I have flight testing to do, weather permitting, over the next few days.
I am adding updates to the 72" Ho 229 plans and I believe they will be ready to be released in about 10 to 14 days.
Best regards,
Jeff

RE: Horten Ho 229 Build
I performed more flight testing today and while the existing fans get the wing into the air, it could use more power. So I am shopping around for more powerful fan units. I am looking for something in the 400 - 500 watt range.
The Ho 229 does not exhibit any bad characteristics. Stalls are gentle drops of the nose and no tip stalling. Stall speed for this version is 11 MPH.
The person that shoots my video is out of town for the week, so all I have is a grainy video of me launching the wing. I sat an old video camera on the roof of my car and hit "REC."
I am finishing up the plans and builder's notes this week.
Best regards,
Jeff

RE: Horten Ho 229 Build
Flight testing continues with the WeMoTec Mini Fans and brushed 480 Race motors. The Ho 229 flies great and I have found it to be an enjoyable aircraft to fly. Flight characteristics are identical to the 70" Twin Speed 400 powered Northrop N9M. It is a pleasant aircraft to fly and it is an unusually striking sight in the air. It does grab people's attention.
I've made a handful of changes to the plans, primarily to make the build a bit easier.
I have released two sets of plans -- an Ho 229 V3 and an Ho 229 V1 -- both with 72" wingspans.
This has been a good size (72" wingspan) for me. It's easy to transport and with the electric power I am in the air in just a few minutes of arriving at the flying site. I'll use what I have learned in this build in the larger and smaller Ho 229 projects now on the drafting board.
Best regards,
Jeff
