Tee Dee .09 with throttle ring that carries a camera.

Before launching the plane, open transmitter and begin to recording. LH X13 drone camera is 640x480 pixels and has a 1 Gb micro SD card on it. After landing remove SD card and insert it a USB card adapter and watch the movie. Movie is AVI format. LH X13 is a cheap indoor drone.

Sincerely

That's interesting. Can you explain that hack to a Neanderthal who is not up to speed on all of the drone/electric stuff ?

Just a thought...

Mauricio just might be talking about the "adjustable aperture" of the silencer/throttle. If my memory serves me right this time, he sometimes uses Google translator to help him translate his thoughts to English, and we all know how the translator is sometimes (although it has improved a lot lately).

For example, for all of us language geeks, here is the etymology of Camera:

----------------------------------------------------------------------------------------------------------------------

camera  /ˈkam(ə)rə/

noun

noun: camera; plural noun: cameras

a chamber or round building.
"the Radcliffe Camera"

Origin

late 17th century (denoting a council or legislative chamber in Italy or Spain): from Latin, ‘vault, arched chamber’, from Greek kamara ‘object with an arched cover’.

----------------------------------------------------------------------------------------------------------------------

I personally have no practical experience on that type of a silencer/throttle, but I do own one installed on a NIB .049 Medallion R/C. It looks like a good design for engines with SPI as it probably has very little back pressure when the outer aperture is completely open. I think I would run it without the black spring steel part altogether.

Sí señor, un acelerador/restrictor de escape con cámara silenciadora.

Mauricio,

I used the muffler on the TD09 on my Cosmic Wind R/C plane but I would not consider it an efficient throttle...the difference in rpm between fully closed and fully open ring is hardly measurable, especially if the engine has non-SPI cylinder where the only impact of the muffler is the slightly increased backpressure with fully closed ring, that slightly restricts the flow of exhaust gases.

With a SPI cylinder setup the fully closed ring will cause some additional peak rpm drop on account of the exhaust gases inhaled under the piston skirt at Top Dead Center position.

I use these mufflers only to control castor splash - not really efficient even if you put an O-ring under the muffler to prevent dripping of castor from the muffler through the gap between the crankcxase and muffler body, because castor will also bypass the ring - and for a slight reduction of noise.

You are right. I couldn't understand camera meaning. I thought that he want to use a camera on plane

Hi everyone, Hello Kari, this is my friend, thanks for making the effort to interpret my language.
The term camera is basically a vault, a single space, it can be:
Air Chamber (on the bicycle for example)
Photo camera (tool to take pictures)
Video camera (Tool to make videos)
Exhaust chamber (Place of engine exhaust)

I was referring precisely to:
Engine exhaust gas chamber
