"My Cox .049' Hot Rod Lincoln..
This engine is a Cox reed-valve .049 2-stroke/glow-engine made from mongrel parts. An integral 8cc Golden Bee stunt-vented late-model* tank-bowl and matching backplate which has a larger .082" dia. venturi. The Needle has a Paul Gibeault recommended mod. to cure air-leaks.

!["My Cox .049' Hot Rod Lincoln.. Hot_ro11](https://i.servimg.com/u/f76/18/50/45/90/hot_ro11.jpg)
The cylinder is a #2 w/SPI.. and has delightful compression. The reed is an old-school beryllium/copper star-type w/circlip retainer. The C-case is an early plain-anodized example.. but more than capable of delivering the punch. You guys know what I'm talking about. It's rat-rod style.. which I kinda' like..
Here's my engine.. with a pair of stock/OEM Golden Bee's that I was lucky to score a few years ago.
This engine will be a test-engine for my latest C/L design; The Fulcrum Flyer.

Re: "My Cox .049' Hot Rod Lincoln..
Thanks Jacob! That's a funny song! I like Johnny Cash.. but I'd never heard that one before. Similar style as "A Boy Named Sue"..
Re: "My Cox .049' Hot Rod Lincoln..
If you want to make it a hot rod you are going to have to lose the #2 cylinder. Increasing the venturi size isn’t really effective when it’s choked down with the single bypass. Good candidate for modification though.

Golden Bee R/C, which also featured a two bypass cylinder with
a throttle sleeve.

Hi guys! Wow.. I appreciate your chiming-in.

Ron, yea.. you're right. I'm having brain-farts lately. Maybe I'm Covid Asymptomatic?

.. I'd actually misplaced the engine that Matt (ExModel) sent me back in July of 2019 (Prize for CEF Cars are the Stars contest) well.. I'd mounted it in the F8F-2.. and had forgotten about it.

It's been a tough model to get flying;: this second engine was easier to start.. but the gear-mains are too close to the CG, causing nose-over/R.O.G. stooge-launches. Luckily there isn't any significant road-rash from the very-few launch attempts. I sOoOo want to fly that airplane. Maybe try adding tailweight in sm. increments..
![Huh...](/users/3015/29/34/60/smiles/3929217648.gif)
I think that I still have a decent C/L flying site though. It's a school/property that was donated by an area philanthropist.. which was closed a couple of years ago. It's a popular dog-walking area.. but there are several spots to fly.. even if you're flying 60ft.+ lines. The fields will need mowing though. There's plenty of pavement for 1/2A R.O.G. launches!
Re: "My Cox .049' Hot Rod Lincoln..
I have a new R/C Golden Bee. Not in the package, just never run. I believe it might be a dual bypass cylinder. I should look at it closer.

R/C GoldenBee, and I'm pretty sure it has a stepped

"Ambiguous".. true-that. Photos of a #3 that I have. It "does have a #3 stamp.. tough for me to photograph..)

my #3 appears to be a later (thick-wall) cylinder, which has flats milled for the Cox wrench.. but its OD has not been ground for a sleeve (exhaust-throttle). It has the later dual-slit exhaust-ports.. and doesn't have SPI.
!["My Cox .049' Hot Rod Lincoln.. Cox_0423](https://i.servimg.com/u/f76/18/50/45/90/cox_0423.jpg)
..and is a single-bypass cylinder..
