.049 Golden Beeee!!!

Twin Cox .049 reed-valve glow engines, configured as later product-engines having the horseshoe-style back-end for an external fuel tank. Shown here on my self-designed Lockheed P-38 Lightning. Engine cylinders are the later dual-bypass ported with "slit-exhaust-ports" type. Propellers are DAL brand 5" X 4" r/h and l/h. Both engines are fitted with Tee Dee style AL spinners which engage my 1/2A electric starter's cone. External fuel tanks are NOS "Perfect" #17 .25oz./7.4cc capacity each.

Thanks for the warning! I hope to campaign a picture during a month no one enters...thus ensuring victory!

Bwahahah!

I hurried up to finish my Boddington Cardinal with the Cox SureStart engine with exhaust control.
Well, I'll get it in next month?
Weather has been crappy to fly too.

My featured twins were a test-bed for homemade-experimental "reeds" a few years ago. Here's a vid

Pay no attention to my nervous "ticks".. The engine on "my right" wouldn't smooth-out.. and I'm wondering if it could have been the experimental reed that wasn't seating correctly..

I had to vote for this one!

The prop is 4.5 x 2 Cox black plastic….. I think the photo angle makes it look bigger….

Jim, The motor runs great and is consistent!!…. I’ve ran it about half a dozen times and they’re all about like the video…. Start it a little rich and it ends up just a little leaner about 90 sec later without touching the needle…. Probably would go a little longer if I replaced the old, shrunken pick up tube…. I didn’t have one at the time….After initial warm up run it will start on about the fifth flip without a prime so tells me it’s pumping good which is another cylinder condition  indicator…

The saving of the cylinder adds a lot of character to that engine…..Was a fun project  One of these days I’ll get it airborne on something “safe”

It does look bigger LOL But was a good run and constant is always Good !

how do you bend a cylinder in the first place?...being a long time musician myself i know bout the nails, pick players aint got nothing on finger players and nothing compares to the warm deep tone of a quality classical guitar. distortion is a great way to cover mistakes and have fun but classical guitarist along with some banjo players dont get the credit they deserve and can play circles around most shredders. and no thats not girly in a musicians world
