Breaking the seal on a Scientific Kingpin

Trace it, scan it, digitize it...please!

I don't think Outerzone has this one.

Not long ago, I opened an NOS Scientific kit, 18-in. Piper Super Cruiser hollow log, same smell as yours, ditto with an old Comet kit, 15-in. Porterfield 65, and 10.5-in. Estes Star Wars Y-Wing Fighter. All have that new balsa aroma.

Cool !Brand new out of the package , it looks good to i know what you mean about the intruders that get into our kits . You going to build that baby or just ogle it

Yea i hear ya on the been a while would love to see and i think you would too get the satisfaction out o a nice easy build // with the restoration skills you have I think it want bee that hard ... take your time // and there is the 2023 Run what YA BRUNG event and would love to have you over there

Bob, just looking at the photos of your Scientific Kingpin kits, except for the easier to build profile fuselage, they follow very closely to the aerodynamic profile of the Cox TD-3, IMO. Once constructed, I imagine that the Kingpin's flight profile would be very similar to the TD-3.

Hi Bob,
Cool thread !
~1967 I mailed a letter to Americas Hobby Centre in New York.
Asking if the 'Kingpin' was built up construction, and how much to send me one.
Did not get a reply...
There was a 'duty/dollar difference' at the time.
Never got to see a 'Scientific' kit here.
Thanks for sharing your project...
Take care,
Have fun,
Dave

Dave, what half-A C/L kits did they sell in Canada at the time? Were they British kits instead, like Keil-Kraft, Mercury Models and Veron?

Bob, I doubt if you really hurt his feelings. May be he already has a buyer?

Hi GG,
I do not want to 'booger' this thread. But..
Here in Canada we got American non glossy magazines.
Half the prices we paid here. ($1.95US for a Kingpin ! )
I was 9yrs old.
I have not seen a Scientific kit here, hence the interest.
Anything Cox, was very expensive.
The local hobby shop owner must have bootlegged Cox stuff here.
Yes, on all the British kits here. Tariff thing back then.
Hi Bob,
I have some paint-able heat shrink covering for you.
Message me. Could be there by the time you get to 220 grit !
Thanks for sharing this project with us,
Take care,
Have fun,
Dave

@Kim, I saw your Kingpin in another thread, downloaded the plan JPG scan.

The little .020 is using one of the new 3-D printed backplates and runs fine, though a little cranky (like any Pee Wee worth it's salt), and I was able to log several flights.  

The Kingpin is definitely NOT over-powered with the Pee Wee, but clips along fast enough to pull big inside loops.  One problem I need to work on is it's inverted flight, but I'm too tired and cranky myself right now to think about it.  Safe to say that it survived it's inverted landing in the soft turf.  We shall return!

I didn't realize that the Kingpin plan shows a .020 Pee Wee installed.

All Scientific magazine ads only show the wing square inches of 50, Bob's box show 62 square inches. What is the wingspan of the Kingpin?

Hi All,
The Kingfish looks very Ringmaster ish...
OR...?
Is it... the other way round ?
Just inquiring...
Take care,
Have fun,

George/Bob,

You asked about the wingspan...one of the Scientific eBay auctions shows this kit right now. The ad indicates a 14" wingspan.

The rib slot count looks right on Bob's fresh kit wood LE. Add a bit for wingtips.

I've scanned many Scientific "plansheets" in the past. For each I always rescan the overhead "mini-view" at high resolution, and then re-save as a full size overhead view. I'd be glad to do the same for this plan, but I don't have an original to work with. Sigh...

Thanks Jim for the 14-in. wingspan info. @Kim uploaded a scan in this thread:

CEF imaging upload rescales to reduce storage. He may still have the original scan somewhere, that may be of use to you. Short of that, his scan upload, even though reduced to 1024 pixels wide, can be scaled to provide a scale print. Even better, a slight more upscaling could allow this design to be flown by a hopped up .049 reedie, Medallion or Tee Dee .049.

I just got the Scientific Kingpin and a P-40 and thought - why not? Made my usual one-time proxy bid and won it. Still haven't heard from the Kingpin guy. I might have to tickle his email again. I would really like to build that broken up kit. No guilt ya know.

Great score on the Mustang, Bob. If you're looking to build one, this should be it. The 23" Mustang has one of the largest wings of any of the hollow logs, and flies very well because of it. I "cloned" one a few years ago, and it is one of my favorite flyers.

Duane,

That is one stunning log! No cartoonist proportions, fabulous finish, and just enough wear on the finish at the front to call this "not a hangar queen."

If you ever got a flying shot/picture from the starboard side (to show the engine), that would be an engine of the month contender. I'd vote for it.

Any chance you care to make a thread just to showcase it? What  did you use to glue the canopy on?

That Kingpin’s a cutie Bob…. I like the treatment of the front end, Just works on this plane…Profile Plus? ….. Looking forward your build…. I think you’ll enjoy it…. Watched Kim’s KP video many times…Nice little plane…

Beautiful work as always Duaneh…. You’ve really mastered nice finish

I had some nice engine runs on the Kingpin years ago with an OK Cub .024. on 25 ft. lines. I really think that even a Cub .049 would seem to overpower the little 65 sq. in. wing plane. Too much nose wt. seems to take away any stunting ability it would have here. My original Kingpin plan has a date code of 1958 that states for a half- A engine. My original Kingpin still hangs in the basement, it has a 13 in. wing span. I have around 30 of the Musciano Scientific plans kept over the years, not as many as to what was produced. I do have a somewhat rare set of plans for the Piper "Sea Scout" that flew with floats from water or wet grass. A project I could never find the time to build an fly Eddy
