UKIE .35 Competition Set-Up

[Jim Catevenis]

                                                               “Ukie” Competition Set-Up

     At the 2017 King Orange Meet I flew my Ukie 35 in Profile, finishing 2nd out of 13 entries.  My score was 481 (winning score was 491) and I flew only one round.
     The performance of the simple Ukie surprised everyone…except me.  In the interest of “open sourcing” of information, here is the set-up.


   *  Stock Ukie 35 airframe.
   *  2 wheel main landing gear from 3/32” wire, with a cross brace of 1/16” wire,
      attached to the bottom of the fuselage.  2 inch wheels.
   *  4 inch Brodak bellcrank, pushrod in the innermost hole, mounted on the bottom of
      the fuselage (now standard location on current models).
   *  Elevator horn length, 3/4”.
   *  Sullivan C-D cable leadouts.
   *  58 foot eyelet to eyelet, .015” lines.
   *  Brodak bar-type handle – Overhang at 2.0” from finger grips.  Line spacing 3 1/2”.
   *  Stock Fox .35 with Double Star Fox tube type muffler and Brodak .25 needle
       valve assembly.
   *  Sig R/C long plug
   *  2” Goldberg spinner.
   * 11 X 5 Zinger wood prop cut to 10.0 “.
   *  4 ounce Brodak deep wedge profile uniflow tank.
   *  Sig10% nitro, 25% castor oil. 3.5 ounces used.
   *  Balance point 2.0” from leading edge at the wing root.
   * A big part of this is the handle, with the large overhang, as it deadens control feel
      just enough to smooth out the control response.  This is also ideal for teaching
      others to fly, as the instructor can fly from the bar of the handle, while the student
      uses the handgrip.  (Leave off the safety thong for this!)

     Jim Pearson has stepped up Ukie production, and they will be quicker to get. Losing a foam supplier slowed recent production, but they are going out now.

Jim:

Have you any idea about the control handle for training that Tom (or Jim Pearson) discusses in the above post? I'm on the lookout for something to have on hand in the event a non-flier shows interest.

Thanks.

Dave...

[Mike Haverly]

Check here, http://brodak.com/reyco-adjustable-control-line-handle.html There are many.

[Jim Catevenis]

Dave- The Brodak handles that are suitable for training are SKU#'s BH-360, 361, 365 and 366. Any of these handles will work very well.  I personally use the BH-360 for this purpose.

Jim:  Very good choice at Brodak, and thanks a bunch for your recommendation. Just what I've been looking for.

Jim-

I swear I am not being a smart ass, but why use a cut down 11x5 Xoar prop when they have a 10x5 available?
Is there a difference between the cut to 10" 11" prop and a stock 10" diameter one?
I have Xoar's on all my planes so far, they just work.

Thanks,
Target

The great plane is NOT a Ukie. The name as designed, and sold by the hundreds, is and should continue to be,..UKEY!

The late Jim Carpenter and I decided that calling it a "Ukey" would indicate the "key" to your learning, having a capable ship in just minutes after opening the box.

OK, Rant over. Rally pleased to see the continuation of this great ARF!

I had all 3 in the series.  The Ukey 40 was powered with an FP 25, the 35 had a Fox 35 and the Ukey 15 saw a Norvel BigMig 15 and an FP 15.

They were all great flyers.  I particularly enjoyed the 15 size.  Was difficult to fit a fuel tank on it.  I didn't get the wing panels parallel but they still flew OK.

   He was out of 10x5 props, so he had to cut down the 11" prop.

[Target]

Ok thanks. Just checking. The 11" prop blades might be a touch wider in the mid span than on the 10" factory prop.
That's why i asked. Checking for secrets, you know.....

[Joseph Patterson]

     U R welcome Chris. You are probably right, but he was just making do w/what he had.

Ok...jumping in to this a little late. I was recently gifted a UKIE 35 (complete except for lines). I seem to remember thinking one of the few posts regarding this plane says to use .015"x58' lines.
Looking around I'm half-tempted to try synthetic braided lines. Any 7-strand stainless steel lines .015" look to be 40 lbs pull. .018 is 50/60 libs depending on brand.

How heavy is the .35?  It can't be 4 lbs.

[Dan McEntee]

   Um, weigh it? It depends on your engine for over all weight.  If you don't have a scale of any kind, take it to the post office or a local produce stand. A scale is a good thing to have, and really good ones are not expensive. 20 to 30 bucks will get you a really good one. Spring loaded postage scales are even cheaper and good enough for most of your needs.
   Type at you later,

Are these still available? A club mate has one but it’s still unflown. I’d like to find one if they aren’t too expensive.

  Google Tom Dixon Control Line. Call him. He doesn't do computers.

[944_Jim]

This thread is bookmarked now. I'm right around the corner in breaking in the fresh FOX .35 it came with.

For all the other listed engines, were they on scaled-down models? Or just different engines on the same airframe? The threesome picture shows what appears to be same airframe with different engines.

My kids enjoyed several of Joe's UKEYs when they were learning.  Here's our only remaining one with an OS 20 fp.  This might be the 35 size..? 

[944_Jim]

Gentlemen,

Foam and wood construction are foreign to me. I have ZERO experience with foam.

I have most of what is needed now for this plane. It is time to mount wings. I've been told to use Gorilla expanding PU glue on the wood dowels/foam interface, and to attach/seal the wing roots to the fuselage. Some research indicates that foam can be destroyed by some epoxies.

I have some BSI Slow Set 30 minute epoxy on hand, and it is accessible locally (big plus). Will this stuff work? If not, what did (or would) you use?

Thanks in advance,
