O.K. so Here is what powers our planes. Since we are in the Ducted fan section, I will explain what or how they work.
What does a ducted fan do, Basically suck air in and then blow it back out Simple as that. It is a two stroke nitro engine installed inside
the airplane that turns a propeller (actually called and IMPELLER) as fast as it can to generate thrust. There are two types. Pusher and Tractor.
They operate in the Same exact manner the only difference is that they face oppposite directions.
First we have the Cream of the Crop the Bob Violet Models .96 Special Edition. At a little over $500.00 USD, On the Right is the O.S. .91 That
sells for about 280.00. Notice the small, slick cylinder heads.
.
Now we move on to a Rossi Pusher. I must admit some of the pictures I jacked from ebay sell ads, so not all are mine. Notice how it has a Larger Cylinder head.
This is what the Fan and Inpeller look like. The has the engine mount and the other line going fromt he center outwards are called Stators, their job is
to try to get the airflow straight.
There are a couple of different type of Ducted fan unit, Byron Pusher, Ramtec, Dynamax and Of course Bob Violet Viofan and Viojet.
Here is a couple of pictures of what they would look put together and ready to install on a jet. the purple handle on the top is an Inflight mixture to
lean out or richen the carburator settings while in flight and the yellow ny-rod is for the throtle.
Here is a Byron unit The pipe faces forward and so there is unrestricted airflow going to the back of the plane. Also notice that it is a 6 inch fan and
fewer blades on the impeller. The Ramtec, Violet and dynamax are all 5 inch fans.
