Henschel HS P75

Hi,

did anyone ever built a HENSCHEL HS P75 in scale with an wingspan of about 48 inch. Are there any plans or drawings avaiable?

Man that is cool! This is one of the experimental designs that I have not seen. I LOVE IT!

I am equally interested in any information about this aircraft (3 Views, Plans, etc).

Go to www.luft46.com Click on Henschel. There is some info and a 3-view. Also some more oddities.

Heiner Skroblin, did you ever build your Henschel P.75 or even find plans for it?

@ Wartoy,

No, not up to now. I made a lot of other projects, where I had more documents. But may be in future, I may start that project. In what size you were interested? What WS?

I am wanting to do one between 36-50 with full control surfaces and landing gear. That is the funkiest langing gear I have ever seen.

He p75

I am building one with 44" wingspan from Depron. Its built but not flown still mixing servos. Running a 700w outrunner, 60Amp esc, 4 cell lipo, and 3 servos. Painted like the one in the picture.

Keep me informed of your progress! Can you show some pictures? How did you cut your parts?

Hand launched and powered at 1/4 throttle to adjust trim. The elevons and canard are mixed with a ratio of 60% canard to elevon movement. Pitch was sluggish. Forum advice from Canard Addict suggest that canards S/B 25% - 30% of main wings, mine was 10%. This was the scale comparison to the drawing from Luft 46. I am in the process scaling the canards to ~25 %.
Horizontal tail is split from 8" facing downward to 4" up And 4" down. This was to assist belly landing. Larger canards will prevent belly landing as this will cause canards to hit the ground or brush in the field I fly at. I'm looking at placing 0.125 music wire for landing gear with 1 1/4 wheels or skids. This will keep wings horizontal when landing and hopefully not allow canard damage.

The main wings are 44" long. Aircraft weight is 42oz.

Redesign rev b

After 10 flights and many crashes I Jjst had alot of issues with trying to make this design fly right. One big issue was that scaling the wing from the drawing led it to have a large camber which caused the ailerons to have no slow speed control. I used a flat profile canard that was undersized and rescale it to 30% of the main wing surface area. I just had to make this thing fly fast for any real control. The Large canard caused porpoising due to over control, linkage slop and later finding that pivoting it should be at 25% of AC it was at 50%.
So now for rev b and the only thing that will look like the original drawing is the fuselage. The wings are going to be more sweptback with an clark-y airfoil and wingtip verticals instead of the single downward facing type. I going to put landing gear instead of bungee launching.

I commend you for your efforts with the design. I've thought about building a few of these tailless/and/or/canard Luft '46 planes, but always chickened out, due to fears of non conventional aircraft. There are a few that just slightly resemble planes like the Stryker, Synape, etc, such that they may be a good start point, and only a start point, for a bash. I may go that route, simply because I could use a proven flying wing as a start point, given that I don't hack it up too badly to ruin it's characteristics.
This Henschel design is one that I've drooled over for years:

As of now, I've stuck to the Luft '46 designs with tails.

You have some great looking planes. I also like LUFT 46 aircraft. What are the wing spans and the size of the fans? I have built a 6' Horton HO X and posted some information in the flying wing forum. Unfortunate that I could not add build information to those that were interested.
Although not flown yet,taxi test and flight controls are looking good.

Thanks. They are around 32" span, using the GWS ME109 wing. The Flitzer is Himax 2025-5300/EDF55 and the FW250 is Don's Wicked outrunner/EDF64, both with EVO 3s-1800. The ME109 wing seems to perform better swept, than on the GWS plane. At one time I had categorized the airfoil type (can't remember which Eppler offhand) and read that they do perform well when swept.
I'll have to look at your Horton.

Version 2

After reviewing the old drawings and design I am thinking of a new direction. The new one will be 60" long with a 65" wingspan. The old version had a flying canard that lead to over controlling the pitch. New design will have a canard with a 3 degree incidence and a trailing edge control surface. Many other projects going on and may take a while to get back to it.
