*Cox Engine of The Month* Submit your pictures! -July 2014-

There are only two of the engines in the world! They're the prizes for the COX Flight Contest. Their name has been chosen as: The COX VICTORY .049. Very fitting, you think, as the were the award for the flight contest.

Mine is mounted to a trusty steed, and will soon be fired-up, and going Mach ONE around the circles. That's why all the secrecy around the airframe. Probably have to change the propellor, to get the utmost out the engine. CAN DO!!!

Looks like a TD .049 and a TD .09

.049 Space Hopper One of my favorites with Tatone Hopper mount, Hiscott exhaust throttle with high compression head and TD 09 spinner - going for an all aluminum look.   

Hi Jason

Yes it is a TD .049 and a TD .09.

The 049 is a specially nice one. With the fine thread needle/spraybar assembly. The best you can get!!

And, from the OTHER side of the Tracks,

My 'Bee-of-Questionable-Lineage' cranking up in the Franken Hawk !!!

Can we choose one engine size please, try to showcase a particular engine. Thank you!

  

I have the lil stinker (same plane) basically. I like the 4 x 2.5 props made for that plane can recommend for the TD .020 great for flying fast. Rare props to source though if you ever see them for sale buy buy buy.
I have collected 4 so far they hold up well being flexible / when boinked in the grass.

I think I only count nine so maybe I sneak in. Are these allowed?
Fair comment Jacob. I have resubmitted my engine with no distractions.

There is a vid on You Tube of one of these running COX "O-Sixty Special" tether car engine   

Sorry for that.

Here is only one. My TD .09

1/2A Nut,

How does the 'Lil Stinker fly? I'd love to get a plane of this size in the air, but I'm sure you can understand my reservations on flying the Art Scholl Pitts!

Lil Stinker started it all with an inverted engine in the 50's later cox remade the mold to have the cylinder upright for ease of use late 60's renamed the Mini Stunt came in many colors they honored Art with his signature colors from 67 to 74 as I recall. They made a all red color one they started calling it the red baron for a short spell anything to juice sales / interest.

As a undercambered wing on 15ft lines the plane is fast loops are easy if you use 30% nitro on a cool day but inverted flight pancakes around. The landing gear is what it its I have only flown over short cut grass 2 flights one day and 3 on another may never fly it again as I want to keep her in good shape. The pee wee is a great fit but if you want to really crank n yank insert a TD .020 should you obtain a more common Mini Stunt version.

The props are great do to 2.5in pitch one of only two designs by cox the other 2 bladed being 4.5 x 2.5 in white (airfoil is thicker) later the foil was thinned out and pitch reduced to the common 4.5 x 2.
The only other option a 3 bladed 4 x 2.5 prop.
Shown in this pic the bi plane weighs in at 100g on the dot vs a 3ch scratch TD .020 at 158g and scoooooots on the 2 bladed 4 x 2.5 lil stinker prop. I want to use the dimensions of the stinker to frame up a balsa RC 4 ch version is the plan with a TD .020 on a throttle sleeve. The top wing 11.5in rather than 10 and bottom wing 10 rather than 9.25in. The rc plane shown is 21in span 64Sq in.

This is a great picture but we need to try to focus on the engine if we can. Don't mean to be such a stickler but it is "Engine of the Month" Thank you, Jacob

Jacob,

I completely understand. I'll have to post an engine picture this afternoon.

Best,
KP

Jacob,

Please reconsider my first post. My entry for this month is this Cox Olympic .15:



KP

I have one of these olympics and 2 of the Sportsmans. What prop size do you go with for speed flying and percentage of nitro?   

Good choice KP

NICE! Thanks! I'll get poll set up in a little while.
