New r / c model airplane project for Cox!

Wow that surly looks great Mauricio. A very simple yet very nice looking color scheme.

Thank you friends for your comments!....
Here is the engine test.
Cox Tee Dee .051 r/c

Dear friends, here I share the flight video of the SCAMP model aircraft with Cox Tee Dee .051 r/c engine...beautiful trainer with very good and fast response to your commands. 1/2A, beautiful category to enjoy.
This video is dedicated to the Memory of my Great Friend: ROBERTO ISHKANIAN, whom I remember permanently.

Excellent, Mauricio,

I like those low passes with the stable low engine rpm, exactly as a trainer plane is supposed to run..

Hello dear Eric, how are you?...Yes it is a Tee Dee .051 r/c...thanks for your comment.
I recently placed a Golden Bee, here the video...

RURAL ROADS
Some time ago I started cycling on rural roads in the countryside near our city. Those roads are full of nature, their simplicity and nostalgia is wonderful, seeing a sunset there, personally makes me thank life over and over again to be able to enjoy that, so simple and so beautiful at the same time, enjoy nature. For this reason I wanted to relate my SCAMP model to those places and thus link a beautiful moment that is recorded there.
I hope you enjoy this simple video, but it connects directly with nature itself.

Excellent flight, and landing on that narrow road, Mauricio..

Very nice, accurate flying as well.
The video flight above, is that 049 powered ?
Throttle response seems very good, a throttled intake or exhaust throttled, maybe both ?

Nice spot of wilderness to fly it in also.

I downloaded then enlarged Mauricio's photo of the Scamp so I could see engine details. His Golden Bee is using an exhaust throttle ring for engine control. I have used these, they work very well on an engine that has SPI (sub-port induction - the air gap below piston skirt seen through the exhaust port with engine at top dead center. It allows an additional puff of air to boost the fuel air charge for additional power).

Both are excellent. Bernie's (Cox Engines Canada) has an added advantage in that the Circlip Ring used to connect throttle linkage to can be relocated from its shown lower position to the slot above the exhaust cut out for more flexibility depending on your situation.

One that I have is an older one from the 1970's from Ace R/C, which resembles Matt's (Ex Model Engines). I had a blast during the late 1970's flying my Q-Tee on Rudder Only with auxiliary throttle on my Golden Bee like Mauricio's.

There is a caveat with these rings. Certain year cylinders may not work if their outer diameter does not smoothly fit the ring's inner diameter, because Cox made changes to the cylinders several times. Ace used to sell two with different inner diameters depending on what cylinder one had.

as I mentioned at the beginning, the idea is to enjoy several engines in action!

Tee Dee .049/.051
Medallion .049/.051

Hello, thank you very much for your comment, yes, as GallopingGhostler mentions there in his excellent explanation, it is a restriction ring, it works perfectly!
