Default First flight of 50% Spacewalker

Yesterday a good friend flew his 1/2 scale Spacewalker for the first time at the H.O.T.M.A.C flying field in Waco TX. It flew great.

It weighs 37.5 lbs and is powered by a 3W-100.

I thought you would like to see a few photos.

Beautiful plane at a beautiful field. Is there any more information about this plane?

A good friend here in Corpus purchased a partially buily 50% Spacewalker in June. The guy he purchased it from said it came from someone who was building 2. Maybe it was you friend.
He is planning on a ZDZ 80 in his. It is all completely framed and set-up now, and he just started covering it. May be ready for Bomber Field in Sept.

Texastbird, there is really not a lot more information other than this: The design was based on the Sig 1/3 scale Spacewalker. I believe it is about a 156" wingspan. Another friend developed the mold for the dummy engines. It is covered with Solartex. Three of these planes were started and Terry if your friend bought his off an RCU add, it was the second one of the three. The first one flew very successfully for a couple of years and very recently was reclaimed by Mother Earth when a very good tail slide developed too close to said Mother Earth. Pretty much totaled but a new and improved version is on the way.

I think I have Jack talked into taking his to Bomber Field. Maybe we will have 2 there.

Geistware, I think that this one has been in on again, off again construction for about 2 years.

Are you going to be at the bme imac show on the 6 and 7? If so, you should bring it out and show us all how to fly. It's an awesome looking plane. Hope to see it this coming weekend.

Ken,
Based on your friend's plane, will Miguels do OK on the ZDZ 80? He wants to fly scale-like with just a few loops and rolls etc.
BTW, yes, he got it from the RCU ad. The seller delivered it to Bomber Field at the June Warbird meet.

Matt, I doubt that Jack has plans to attend the BME IMAC show, but you never know.

Terry, I fly a 1/3 scale Super Decathlon weighing about 35 lbs with a ZDZ80RV. The plane flies really good. Big loops don't require diving first and do not use full throttle. It will go vertical probably 500' before it really starts to slow down. The 80 is turning a Bambula 26x10 at 6000 and using a Bisson Pitts style muffler. With a pipe it would probably do 6300. Based on all of this, if Miguel will keep the weight below 40 lbs, he will have a real winner with the 80 in the nose.

Ken,
again, this is a superb looking model airplane. Why don't you talk Jack into posting some pix of the building process, or even some close-ups on the finished model?

You mention 3 of those being/having been built, is Jim Dietrick's the one that was totaled? Or is that the one that you mention as possibly being the other one at Bomber Field?
Just curious...

Marcus,

I don't know if Jack took any construction photos. I'll ask him. Jim took the photos that I posted. I'll make some close ups when I see the plane for the first time. Yes, Jim's was the plane that crashed. He has a new one under construction.

Come on up to Bomber Field in September. I think Jack will have it there. Bomber Field is only a few countries north of where you fly.

Ken,
I would be glad to come to Bomber Field or any other big event in the USA - it's been 9 years now since I was last there. But for now I'll have to wait a little more. My business is taking me more in the direction of the surrounding countries as well as across the big pond. However next year much probably I'll be coming to the NY and Pennsilvania area. And once being there I sure will try to sidejump to visit you...

Back to the Spacewalker: It's a pity that beautiful model crashed - what happened?

See ya 'round

Great looking airplane. We have just finished framing a half scale Spacewalker as well. Would love to talk to the builder, have questions about servo size, weight and balance. Please let me know how i could contact him.
Thanks
Jack Wilhelmi
