Whats a space hopper like this worth?

Tee Bee

I think it's worth $4, but I'll give ya $5 for it just because I'm feeling generous today.

Thanks Tee Bee,
Your generousity is overwhelming as is you ability to be informative LOL[)]
Yeah I don't have a clue either.

EX Model Engines

I'd say between $60 and $80 if there are no defects and good compression.

Well it is a rare thing I guess so here is the deal. Its ON Eba^ in a lot of 049 stuff and is at $50.00. I am NOT going to go for it so have at it boys. I am going to limit myself to TD 09s, 049s, 051s, Black Widows and Sure Starts. Thats plenty for me.

air-madness

Yeah, that's one of those engines that everyone hated. I think it's worth about 3 dollars[)] I'll give you...

If one of those engines had all the little tricks a KillerBee has, it should be a screamer.

Either I have looked in the wrong Eba^ haystack or it is no longer listed.

I have one I bought at the time. Gave it to a friend and got it back a few years ago. The piston is a two part piston. I replaced it with a modern Cox piston and ran it on the bench. It is a powerful engine, as was the Thermal Hopper. Going to build something for it one day.

The Space Hopper was the engine of choice till the TD 049 came out. Memory is foggy but i believe that they were 6/7.95 when they were available in the 50's. Used them in 1/2A speed at the time. It's a desireable motor to have and I'd keep it and enjoy it.

Wow
I thought it had a couple days left yo go. I suspect they got a clue and pulled the listing.

Set a $200 reserve on that auction-site-not-to-be-named and see what happens. Sometimes folks go nuts and you get way overpaid. Most of the time NIB gets big money from collectors.

If that Space Hopper was mine I'd cherish it and fly it half a dozen times a season in something like a 1/2A sized Quaker. Spares might be problematic, but where are you going to get a sweeter glow engine in the $60 - $80 range?

jjscott

Does anyone have any hard data on what a Space Hopper is worth - like auction sales or a forum sale. I've got this feeling that a Space Hopper is worth more than $60 -$80 but no evidence to back the feeling. What happened to the one on ebay did it disappear before selling?

Well
I could not find it again after 2 LONG looks. it was in with other stuff and labeled funny and it was not NIB. but it looked OK.

It is rare to see a good condition space hopper sell for over 80 dollars, I've had them on my watch list for a couple years now.

Made only one year, 1959.

The new in package ones can reach 200 bucks.

OzMo, is this the lot you were talking about?

It's the only beam-mount reed valve .049 engine Cox ever made. The case is unique to this one model.

It is a beautiful engine design and very compact, suitable to speed models of the day.

Of all my different Cox .049 engines this will be the last one they'll pry out of my fist.

yup thats the one.

Picked this one up for $68, and the condition it was in looked like it should have been another ten bucks or more less.

I asked the seller if there were any wrench marks on it at all before I even decided to bid on it, because I wanted to polish one out for my collection.

The problem with finding a good example, is Cox engines (for the most part) don't use screws. Each part is its own "bolt", and if ever touched with a wrench you'll see it.

It has a later piston, and possibly the cylinder isn't the same as original...and finding an original style glow head is pretty hard to come across. If I am correct, the original glow plug the fin diameters are all different. Later ones the first three fins are the same size.

I have seen them with two styles of fuel nipples also...one is the Thermal Hopper style, where it is not conical, the barb is rounded and located back from the opening a little. The other the same as the current TD's, unanodized. I have both, I dont know which one is correct.

The one I have pictured has an original Cox twin needle valve assembly that was issued out as an accessory for the Thermal Hopper. From what I have learned it is used as a "throttle" for the engine, using a third string on control line...using it to pinch one side of the twin fuel lines to lean it out and go faster.

Oh, another thing I should mention if your looking for all original is the prop spinner. It should have no lip at the prop end like a TD, and it is not the same diameter as a TD either, so don't be fooled by a TD that has been shaved down.

EX Model Engines

JetpackReally nice engine, and $68 for that is realy a great deal in my opinion.

jjscott

Yes, that is a beautiful engine.

Has anyone ever done comparisons of the various Cox performance engines? I'm thinking about:

Thermal Hopper
Space Hopper
TD
RR1
Venom

Did they just get better as time went by?

Jim

jjscott

To keep pricing current, a NIB space hopper just went for $163 on ebay.

I watched that one end also, big cash huh? That one was mint in box though with all the goodies they came with. I would be proud to have that one, but wow the price. It even came with the white cardboard sleeve which is pretty rare to see. Someone correct me if I am wrong but shouldnt the yellow on the package be reflective gold hot press printing?

Here I found a pic in my archives that shows metallic printing. For an engine made only one year, they sure kept busy with changes - even with the packaging.

build light

As much as the Cox company did, I would bet they did not print their own packaging. To explain what may have happened in these two differences I would guess that the original metallic printing was so expensive that they quickly changed to the less expensive printing method.

Another theory might be that a competing printer may have offered the metallic printing at a very competitive price and these may indeed have been used after the non metallic. Who really knows?
