Cox Hyper Viper

[Larry Fernandez]

A couple of years ago, I picked up a Cox Hyper Viper at a garage sale.
Except for the wing, which has crushed and folded in half, is in excellent shape. I’d like to get it back in the air for the neighborhood kids to fly.
If any of you happen to have a Hyper Viper wing that you would consider selling, please let me know.

If a balsa wing will work, check with Greg.  https://stunthanger.com/smf/southridge-cnc/hyper-viper/

  Keep your eye on eVilBay, spares and parts planes show up there from time to time. If you know someone that has a Chipmunk or ME-109 wing from the second generations of those models, one of those may work.  The airplanes are all basically the same  in the way  they assemble. I may have the stuff needed to check that out, and if no one beats me to it, I can check on that this weekend.

Thanks Dan. As I said, except for the wing, the plane is in excellent condition.
I even found a new set of decals for it.

I have two vipers. One NEB the other unused hanging in the shop.  I’m not wanting sell but I think I could trace airfoil cross sections some how (have never had them apart) if that might help you with a built up wing type repair? 

[George Truett]

Someone on RC Groups has 2 sets of Cox foam wings for an FW 190, no idea if it's the same airfoil.

Thanks George, I have a couple of those wings myself. They are completely different.

Hi Tony. I’ll probably use the damaged wing for templates to build an new one.
Many thanks.

Hi Freddy, I don’t know what it’s worth, but I would bet that it’s worth we’ll over a hundred dollars.
I don’t want to buy a new, pristine plane just for the wing. Im hoping to find an undamaged used wing.
Thanks anyway.

    Those were for the original Cox ME-109 and Chipmunk. The fuselage had a stub spar molded into it, and the foam wrapped around the wing root and stub spar, and was held together at the trailing edge with tape. They were light and flew pretty well, just not durable at all. They discontinued it and several years later came out with the second generation with a solid foam wing. That is the version that Ted Fancher did a review on in his column in Model Aviation which included a few modifications that made it fly and handle much better. Cox took that to heart, stopped production, incorporated Ted's changes and resumed production with a different part number , as I recall it at the time. The model was capable of the whole pattern, you just couldn't do it on one tank full of fuel. The beginners pattern was possible, and I won a contest for these airplanes that was held between rounds at Bob Roger's stunt contest in Quincy , IL years ago.  The Hyper Viper was the work of one Mike Pratt, and I believe that it's set up and lay out was similar to the revised second generation Chipmunk. Maybe Mikey will see this and jump in and provide some clarity, and Larry Renger knows a thing or two about the story also. I still hope to see if a Chipmunk wing will fit a Hyper Viper yet today, and the day is still young.

  Hi Larry;
    Well, I just checked a Chipmunk wing against the wing and fuselage of the Hyper Viper and they are way too different.  I can think of a couple of alternatives. One, is if you have a decent center section, you could use it as a root section for a foam wrapped wing like the older Cox wings, just have to add some sort of stub spar. Another and more likely is to see if someone has something similar in a 1/2A combat foam wing and do what you need to do to make it fit the fuselage. The H-V wing is more simple that the Chipmunk/109 wing, with just a few holes in it at the center line for screws and such to clear. The Chip wing looks like it was molded and has grooves and such for it to lock into the fuselage. It has a 7 inch root at the center line, and if you can match the taper you just join the wing like you would any foam wing and maybe re-enforce it with silks pan and white glue, then put what ever holes you need into it to get it to mount. You could just finish off the whole wing in silk span and glue, or skin it with gift wrapping paper for some durability. This sounds like a better way to go and not too much work for a guy like yourself. If you have anything left of the original wing you may be able to see everything that I am talking about, or if not, let me know and I'll send you some pics. Another alternative would be a wood wing, and Southridge CNC may have a plan available for the model he was putting out. H e was having some sort of health issues so don't know how active he is right now but worth a shot.
  Good luck with it,

You're allowed near kids?

Ouch
I would expect something like that from Brett but not from you.

Hi Dan, thanks for checking. I dug out the Cox Chipunk (later version) from the rafters this afternoon for comparison, and it turns out that you are correct, the wings are different.

Thanks again!!

   I told you Howard was not ranked high enough, he is one of my few worthy competitors.
   
    As a Grand Master, I feel I have some obligation to "pay it forward" to the craft to offer my opinion on the quality of smart-assery . I would rank this entry as about a 8.0-8.5 - a little out of left field, too much lag between opportunity and delivery, with no prior establishment of the premise, and a bit on the cruel side, but otherwise a very creditable effort. Solid B.

    Compare and contrast the "brown Ferrari" thread, where it was set up carefully with the forethought,  grabbed the opening as offered, engaged other worthy competitors as unwitting straight men, and then delivered the coup de gras nearly immediately with perfect timing. Melvyn himself would have been proud.

Just having a thought here.   When do you decide to cut your loses and just go with a completely new/ different build for the kids to fly?  I applaud the effort to get the Viper flying and know the effort to do so is not over yet, but..... There is another way to go right?   Just sayin!  Ok back to your regular scheduled programming.

   You do have a point here, but but using the H-V main body has some advantages. The fuselage assembly with tail feathers, engine and fuel tank is a pretty tough combination. We flew some that Mike Pratt brought with him once at the KidVenture circles at Oshkosh, and the biggest short coming on it was the wing. It would only take so much abuse compared to the other airplanes. The wing can be repaired most times, but even that can only go so far. If a replacement wing can that can easily and cheaply be devised that takes a minimum of time to fabricate, you are back in business in short order. not the optimum trainer, but as a stunt trainer for someone who can do some of the tricks, it is a step up, I think. You already know that the engine and tank can operate more or less trouble free. And it does look pretty cool also!  And on the other side of the coin is your option of building something else, and look for someone that has a good wing and is looking for a parts plane.

Gee Howard, how are you going to be able to sleep tonight?

Dan.  Given enough time parts will turn up from somewhere.  When I read these types of request my mind tends to put a more immediate need to it then may be necessary perhaps.

I know for a Fact Phil Cartier can cut the hyper viper wing set....jest saying...Bob Hunt can also....very very basic wing....even if Cox patent n copy right
