UMS Engines - CH Ignitions

Check out this new line of gas engines...

Splash

New from CH Ignitions...

This just in from CH:

Adrian Ciulei, the owner of CH Ignitions, has just introduced a brand new line of affordable gas radial engines from UMS technologies. All CNC machined from aircraft grade aluminum stock. Cylinder construction is ABC type (Aluminum body, Brass liner, Hard chrome plated) for durability and reliable long lasting performance.

There are 11 different models to choose from:

  • (5 cylinder) 55cc, 75cc, 125cc, 180cc, 210cc, 260cc.
  • (7 cylinder) 50cc, 90cc, 160cc, 260cc.
  • (9 cylinder) 115cc
With all these options it makes it easier to match up the right engine to a greater selection of model aircraft, that would look and sound so much better powered by a more realistic four stroke gas radial.

How to TIME an RC Engine, by CH Ignitions & RCEXL (33 min 25 sec)

All engines are pre-run and tested for quality control at the factory. Engines include a factory installed collector ring muffler, electronic Ignition, motor mount, drill pattern template, auxiliary fuel line pump, pushrod with ball link for throttle or choke connection, operation manual, and one year warranty.

CH Ignitions is now the USA distributor and will handle sales, warranty service, and replacement parts.

Please visit www.CH-Ignitions.com for more information and complete engine specifications.

Is that Van Morrison in the background? And why does it run cooler with 100 octane? How often you gotta lube those open rockers? I do like me some radials, though.

They are also working on the Inline 2,3,4 cylinder. I will know more in the Fall when I go to the factory. I will look to see the boxer option but that will have to be a study of demand. Will be based on existing parts .

Horizon Hobby still handle the Evolution brand that is their brand and mostly GLOW.

The UMS is based on the same design but redesigned for Gasoline operation, more improved .

Machined heads from AL stock not cast.
Valve seats inserts to support higher temps from gas operation.

Bigger cooling fins on the cylinders,

Stronger cams materials and heat treatment process.

Working now on NEW CDI's between CH and Rcxel that we develop as we speak and test.

ALL the North America service and parts will be trough CH , I will do the service and parts.


Thank you
Adrian

And I thought that the UMS was connected to/ or a derivative of Seidel? But I looked it up and Seidel seems to still be operating as as separate company....

Yes and NO.

UMS are gasoline engines with CDI's. and a NEW line of 5 CYL Gas .
Evolutions are GLOW and you have the 160 and 260 7 cyl gas but looks different.
Sidel...not sure what they do this days I heard all kinds of stories...
But confusing as it is...be glad that you have choices .
Before you had Moki ... mostly 5 cyl, big $$$ the only kid in town.
Now you can choose

Let's not forget the Valach 250 and 420, but like Moki, a bit expensive for most. I most definitely would try one of yours if there was a boxer, those are the style I run. The one in my Avatar has a Valach boxer in it.

I had one of the UMX 260cc motors from Horizon... constant problems with oil leaks, and the motor never ran consistently... great one day, very sluggish the next. I never got the motor off the ground, sold it and put a Moki on my plane... problem solved. I hope UMX worked out their problems, from what I read, there were a lot of people with the same problem as me.

Glad to hear that! They are great looking motors, and it will be good to have options for radial engines.
