Ah ok, thanksI think the plans have to be available to others or able to be repeated by others

Oh, I didn't read that part of the challenge. In that case, I'll definitely not be able to join as I don't make plans for my scratch builds. Anyways, have fun guys!I think the plans have to be available to others or able to be repeated by others
Yes, this will be a first build that i make plans for however i think i know how to male plans, if not… YouTubeOh, I didn't read that part of the challenge. In that case, I'll definitely not be able to join as I don't make plans for my scratch builds. Anyways, have fun guys!
I'll just sit this one out if the requirements include plans, seeing that I chose a complicated airplane and really just don't like making plansYes, this will be a first build that i make plans for however i think i know how to male plans, if not… YouTube
you can make a master series one and one with the lathe just to see how it fliesJust asking, could i use a lathe and some foam to mould the fuse of the HE-176 or would i have to make it like the master series?
I'm not running the challenge so I can't tell you one way or the other, Maybe @kitten01 needs to clarify. Not trying to discourage you or anything like that from participating, hope you do, I'd like to see your plane flyRatcheeroo
I have available all the drawings that I used to build it so in theory anyone else could but I suspect if they could they could just as easily create them as I did from the internet. As it includes many printed parts, I do have the stl files, but you would need a printer to create them.
I did say in the first post it was not an FT type of construction. If such is required by the challenge then my Heinkel would most definitely not qualify but I will still follow the challenge progress with interest.
One thing I may suggest it that you get rid of the stall category, because quite a few of these airplanes will inheritly have a high stall speed, take for example @quorneng 's jet, that thing is probably going to have a stall speed of mach Jesus because of the stubby wings among other things. Just a suggestionDetermining the winner:
determined based off of stats by builder/pilot and community decisions.
#1: does it fly? 5 points. if not 0 points.
#2: Ease of build? 1-10 points.
#3: In air handling? 1-10 points.
#4: Scaleness? (compared to actual aircraft) 1-10 points.
#5: Stall speed? 1-10 points. lower stall the better
#6: Flight Envelope? 1-5 points. 5 for slowing down to a crawl, and also being able to travel fairly fast.
MAXIMUM POINTS 50.
PLEASE SUGGEST SOME MORE CRITERIA FOR JUDGING

in terms of making it as easy to build and power.... if it is possible i would suggest you use an edf.Im going to try the HE-176 which is an experimental rocket plane, would i be able to use model rocket engines (seeing as i have 5 spare) to power it or would i have to buy and edf.
I'm all about history my friend, no apologies necessary. You obviously think out of the box so to speak and like to challenge yourself . This is a very interesting plane.My He 162 is really a bit 'over the top' as far as information for anybody else to build so I might try a Heinkel using my simpler? 5 mm XPS foam board technique as I have had some success with it but unfortunately none are Heinkels!
So how about an EDF He 178 EDF.
Actually quite a challenge as it used a tiny jet engine which results in seriously inadequate inlet and exhaust sizes for an EDF.
The history of the He178 is interesting in that Hans Von Ohain designed, built and patented what he called a 'garage' jet engine which just about worked in 1936. It was done completely independently of Frank Whittle. His professor at University wrote to Heinkel who arranged a meeting with Heinkel's engineers present. Heinkel could see the potential and set up Ohain in a lab with Heinkel's engineering facilities at his disposal.
The first engine made worked but only when using hydrogen as a fuel. The second HeS 3 used diesel fuel and was reliable enough for flight. All this work was done in secret and as a private venture as was the Heinkel designed small plane, the He 178, to put the 'flight' engine in. It achieved the first flight in 1939. It had a modest performance which did not impress the Luftwaffe officials when it was displayed to them
The He178 V-1 that flew in 1939.

Note the typical Heinkel wing shape. Secrecy resulted in very few photos of the V-1. The second prototype V-2 had bigger span straight taper wings. It was better photographed but never actually flew.
Although the RLM (German Air Ministry) were very interested there was concern that as a aircraft manufacturer Heinkel's team were not experienced enough to develop the jet engine. This view did not impress Ernest Heinkel who continued to fund development independently with the result that none of the more powerful Heinkel engines got past initial development before the end of the war whereas engines developed by engine manufacturers Junkers and BMW did.
Even in the UK it was only the 'intervention' by Rolls Royce that got Whittle's engine into full development and series production.
Apologies for the history lesson!
