Med .09 Intake Throttle

All the images are inverted. Not sure why.

Troy,
It appears to be the intake throttle portion of a Hiscott throttle/muffler assy.
It appears just opposite of the way the Hiscott unit fits on a Med .049.
I was not aware that Hiscott made such set up for the Med.09.
It could be a one of a kind.
Many here have more knowledge/history that can better answer your question.
FWIW, Steve...

I think that's part of this from Cox, although the linkage arm looks different.

Interesting! Thanks, guys. I wonder if it was effective without the muffler. Will need to do some test runs on it.

I think Steve is right i have all sizes of the slide throttle and the arm and throttle bar are not the same + the slider has a hole in the center The .09 is a odd one and hard to get . ck. these pics out info .. https://www.mh-aerotools.de/airfoils/cox_3rdparty.htm and then https://www.mh-aerotools.de/airfoils/cox_medallions.htm#Medallion%20.049%20R/C

Thanks. I now see how it works after looking at those pics. The odd of stumbling across the matching muffler are probably very slim. Oh well...

Heck as you said try it the way it is there may bee a reason the muffler was removed ? I have not had the honour of owning one > Would bee interesting to see if it would still throttle ( it should ) But how good is the Q

Hi all, i resume this old post because today i received cox throttle control as in pic for my medallion .09, and surprise, it doesn't fit.
inner muffler diameter is 17,6mm , .09 external diameter 18,5mm
checking the reason, i'm looking if in period production cylinders shape was changed, but no good response...anyone has few 0,9medallion pictures to show me? kit is declared for 0,9 and easy to fit ( lol ) but the only way to fit is enlarge diameter, but i wouldn't modify that rare kit.

thanks all

Hi CT,

Give me a bit to check my Medallion .09s. I seem to remember one (if not both) have a shiny section at the base of the cylinder(s).
I had assumed they were for throttle rings like in throttled Babe Bees. I do have a decent electronic dial indicator, so getting good measurements will be easy.

Oddly, I bought a regular muffler that won't work. I seem to remember it was a sloppy fit on the cylinder. My muffler is the round disk that encircles the  cylinder, with the black spring band that slides/rotates around the he muffler to expose exhaust ports for a prime, and has a small stinger for an exhaust pipe. Again, just like on early Babe Bees.

If so, we may have an opportunity to trade parts so we both wind up with a working setup. Where are you located?

I'll have that info/pics to you in about two hours.

Hi thanks for your answer, i'm from Italy i can do now a pair of pictures of my .09 and throttle

I'm far from an authority on the 09, but I'm pretty sure the earlier models had thin wall cylinders (I have one of these), later ones were thick wall, like the early and later model 049 and 051.  

I know that the muffler/spraybar throttle for the 049 Medallion was made for the thin wall cylinder. I don't know but would guess that the same would apply to the 09 Medallion throttle as well.  

That might be why the engine you have doesn't have the muffler portion Tee Bee, it appears to have a stepped thick wall cylinder, probably not stock on the Medallion.

Hi, thanks, it could be correct...i just done few pictures

Cescoturbo, WELCOME TO THE FORUM!!
I've been through this with the Medallion .15.
I bought a muffler throttle and it will only
fit a thin wall cylinder.

Hi CT,

Thanks for your patience. I have to apologize for retracting the offer for a potential trade. It would cost more to ship piston/cylinder sets back-and-forth internationally than the sets are worth. I do hope the data sets help you identify what you need.

However, I did collect some data for you. Each cylinder data set was made just above the exhaust port, right below the first cooling fin, and at the cylinder base where it touches the block.

Additionally, the muffler was measured for the inside diameter of the top disk, and at the bottom of the body, where the bottom of the cylinder would close off the muffler base.

Silver Cylinder Engine:
Top     18.36 mm
Base   18.36 mm
I call this a parallel ground cylinder, and suspect it could be used with an exhaust restricter throttle (like Babe Bees).

Black Cylinder Engine:
Top     18.50 mm
Base   18.50 mm
I call this a parallel ground cylinder, just like above.

Cylinder Only:
Top      17.54 mm
Bottom 19.04 mm
Since your muffler splits across the cylinder, this cylinder seems to be a likely candidate for you.
This cylinder is stepped-ground with a difference of 1.5 mm from top grind to base grind. Because the bottom is wider, I doubt it was made for an exhaust throttle or factory muffler like mine.

Muffler Top Plate hole:
18.41 mm
Muffler Body Base hole:
18.91 mm
The top plate would fit only the top-most cylinder (silver), but the muffler body would be loose around the cylinder base. The top plate is just a bit too small to fit into the black cylindered engine. Neither piece will fit in the bare cylinder listed last.

not real, small package fly fast and cheap, part of my cox collections and spare parts come from usa, if package is less than 50dollars also duty taxes vanish. so please, let's me know if something could be interesting. here in italy vintage engines are starting a new era.

my muffler has same inner diameter top and bottom, so i guess wall has to be parallel cyl....i'm thinking my medallion has very low value, i could put cylinder on lathe and do a pair of groove with righ diameter, so muffler one time fitted, could rotate only and not goes un and down

Hi: I am happydad from the US and I think I have one of the muffler-throttle assemblies you are talking about in my cox box somewhere. It was supposed to be for. .049, but was too large. I will try to find it tomorrow and measure the inner diameter of the muffler and post the pictures for you so you have more information.

Bob: do you still have the measurements for the Medallion .15 muffler-throttle?
I quickly measured the one i have and the inside measurement was 20.7mm.
More after i get home and take pictures and post them.

so it appears mine is a medallion .15 muffler-throttle.  see pics of all parts. since i have no medallion .15 engine, please pm me if you are interested. all parts will me shown.

overall pic.


measurement of moving throttle part in mm.


measurement of bottom side of muffler


measurement of top side of muffler.

please pm me for further info.  happydad.

i'm waiting this

it could fit

Hi Cesco, I don't think it will fit. I tried the
throttle on a .15 stepped cylinder, and it
didn't fit. Sorry.
