Flying with CO2

When I started flying again in the power field the1950s, we only had the internal combustion engine are generally available are the terms to appear in the press from time to time in 1960 on the use of CO2 engines

Unfortunately, the internal combustion engine has some disadvantages, particularly if that out loud, where no silencer for this in those days, and as a line of flight control at its peak, had started a number of complaints about noise in the role, causing the loss of many Flying Sites, producesstarted, silencers for many of the larger engines and there, where for the production of the first attempts to produce electrically powered aircraft, said that the disadvantage has been very difficult to batteries, engine size and the remote control at the time

Some CO2 engines began to appear in Britain at this time, Bill Brown in the United States had built the first engine of CO2 that ran in 1942, apart from the Brown British American Shark, Telco and Model czech, were available to and aboutEarly 90s, that's how things remained,

Enter Gasparin Stefan. For the first "international" in Nottingham in 1991, this name was only a few people outside the model fraternity in what was then Czechoslovakia, known as a couple of very small engines Stefan made for his friends.

The advent of the Velvet Revolution, which allowed him to consider the sale of its engines in the West and in this sense has got together with a small farm, instruments for the total size of the aircraft is applicable (usuallyRusso, the company was then hit by a sudden drop in orders) with the idea of ​​producing for the plant in a new series of engine design for him.

Am Inter Scala, Gasparin engines were the editors of the magazine model czech, Otakar Saffek, an international court FAI, stunned a group of models who do not believe, an aircraft model could be shown in the form of a 2 oz can of tobacco , let alone have an engine of the working group is installed, it actually worked.

So today there is now aOpportunity to conduct a series of small, scale, light, sport, type of aircraft competition, either for the construction of free flight or RC, indoors and outdoors. It's the name. A safe, clean and satisfying to fly. The power for its size is produced surprising.

A word about how they work. The CO2 and steam engine working on the same principle. Are engines of growth. The main difference, the fuel. The engine uses CO2 gas generated from liquid CO2, as opposed steam. The steam and gashigh pressure through a small tube from the tank in a room with a ball valve seat and fed to the cylinder head. When the piston can contribute is centered at the top, the ball moves from home (to TDC), rushes gas pushes the piston down. The exhaust gases through the gates, as the shaft swings around toward the bottom dead center. When the piston comes back up, the cycle is complete. The motor runs in both directions.

The information presented here is veryGeneral and the newcomer to remove CO2 that some problems may arise not lend a hand after a couple of key processes. Following this procedure, a high level of satisfaction and good old fun will be yours.

Engine Maintenance: If necessary, open to clean the engine, dirt or debris from a bad landing, replacing a damaged seal, etc., install only the parts by hand, nut, cylinder head, fuel tank, nozzles, etc. Do not use pliers orany type of key.

Lubrication: It 's very important to keep your little jewel well-oiled. For the oiling procedures are mfg. Instructions. Every six to eight flights should do it. make a small amount with an oiler August Not oil. Extra oil will not hurt, but the engine is, if done repeatedly damage your aircraft.

Chargers for the C02 engine.

Currently there are 5 different chargers.

In the UK, we usually use only 2 simple `The 'Art spartlet that8GM bulb uses to produce soda water is to buy low, but can be very expensive, used a box with 10 light bulbs that last only 80gms of gas and, in general, the larger engines of the fillers are small impractable as the tank has a greater capacity to fill the bulb. In this case, by far the cheapest way to get the engine is responsible for most of adapter to use in a "Sodastream" fits the cylinder. These are generally around the world in some way, but make sure if you do not have "use Sodastream"Cylinder, the pressure relief valve on the side of the cylinder and not integrated into the head of the valve.
use in countries where there are 'Sodastream "bottles available, it is often possible 12GM bulbs, typically used for air rifles. For this bulb size will be needed for the deluxe charger with 8 or Gasparin 12GM bulbs will be used.

In Britain, the `Sodastream 'cylinders from Boots, Tesco, etc. can be obtained, simply purchase the cylinder onceFrom here, the empty return and exchange for a filled for less than the cost of a box of light bulbs. Each cylinder contains 250 grams of gas and can last forever. The incorporation of C02 engine is very simple, the hose from the engine to the tank can be easily bent to any desired shape, if Parin gas pipe can be wrapped around a pencil, getting the game side. The only rule is to be noted that the reservoir should be mounted more than 45 ¡from vertical. It does notDifference to the engine, how it's installed.

Filling the tank can be made in two ways. The filler pipe of the engine down and die on the charger, a "gas" is done, this is to trim and flight-testing and under conditions of high humidity. this is very fast to avoid burning the gas, can lead to freezing of the engine's cylinders and thus very poor performance.

The other way to free a charge "fluid." Thisis with the charger to the bottom and top of the feed pipe of the engine is facing. LPG is introduced into the tank and takes longer to burn a fill gas which is much longer than the engine is running. Warning! E 'possible if the pin on the piston lifts the ball valve in the head at the time of the survey to obtain the liquid gas into the cylinder. If this happens and you swing your arm, the result is a destroyed piston ring, which is frozen to the cylinder wall bySub Zero Gas. Always check that the piston is at the top of its travel before filling the tank.

If you are unlucky and freeze the ring, it is very easy to change, just unscrew the cylinder all the safety ring and all, and lift the piston. You will see the ring on top of the piston, the shot out and replace it with a new one, do not forget to put a little 'lubricant of C02 on the first ring of the cylinder carefully ease upgrading, do not forget, before putting the ring Securitythe rear of the cylinder, put gas in the tank and tighten the cylinder flipping between the rotation of the arm, is set to the correct speed, then lock the retaining ring. It 's simple! MA! If you form a ring with a smaller engine, G24 test below, I recommend you take a glass jewelry so you can see what you are doing!

C02 engines are now reliable and relatively inexpensive to buy. He looks at a model that should have a good engine and, in particulareven though they are virtually silent, the noise that make the most realistic and do not offend the neighbors or the public, when in use

Setting the speed of the engine RPM can be changed by rotating the cylinder. Nut, turn clockwise cylinder higher revs. RPM counterclockwise decreased.

Choose the size of the motor for your model: See mfg. Manual. However, it is advisable to install a slightly larger engine throttled down when a small motor to berunning wide open the desired performance.

model of assembly of the tank: Locate the tank on the center of balance, or slightly forward. The weight of the container varies with the amount of liquid, and if it is too far from the center of balance can be cut planes in flight.

Model Weight: Build light. Keep Wing loading. patterns of light look better, especially of scale, as they fly more slowly.

Good luck and happy landings
