Summary of Contents for Titan ZG 45PCI-HV

  • Page 1 Instructions Toni Clark practical scale GmbH...
  • Page 2 Instructions Titan ZG 45PCI-HV 5 years guarantee for TITAN model aircraft engines More than 20 years experience with TITAN engines plus our quality control allows us to extend the period of guarantee from one to five years. This guarantee covers the engine and the ignition only.
  • Page 3 Microprocessor Ignition, given towards the end of this manual! The Titan ZG 45PCI-HV is not a complicated engine, it is a well proven industrial two stroke engine. To ensure your engine reaches you in perfect condition, we have specially trained people to completely strip each engine down and thoroughly check it.

  • Page 4: Rigid Mounting

    Instructions Titan ZG 45PCI-HV Rigid mounting The rigid mounting of your engine has the attraction that it is cheap and simple. A well constructed model can easily withstand the vibration. It is preferable to fit the receiver in a Balsa box with plastic sponge material as opposed to fitting the receiver to a rigid Balsa sheet with rubber bands or similar.
  • Page 5 Cooling air opening For cooling the Titan ZG 45PCI-HV it is not necessary to have a specially large opening in the cowl. But it is essential to ensure, that as much air as possible entering the cowl flows through the finning and around the carburettor, which also needs cold air. Air takes the path of least resistance and will not normally flow through the fins, unless you take positive steps to force it to do so by means of air-ducting.
  • Page 6 Instructions Titan ZG 45PCI-HV Ignition installation in the model The most important rule covering battery ignition systems first: Never ever switch the system on without the spark plug cap being on the spark plug! Keep all parts of the battery ignition as far as possible from the receiver, mini- mum distance being 15 cm.
  • Page 7 Instructions Titan ZG 45PCI-HV Pickup installation Fit the pickup head with the power coil screws as shown. The ignition timing is automatically correct and cannot (and need not) be adjusted. The gap between the pickup and magnet is not critical, it can be anything from 0,2 to 2...
  • Page 8 Instructions Titan ZG 45PCI-HV Battery With the new PCI-HV ignition we have set the greatest value on a really strong spark. Of course, high- energy sparks are not possible without higher input power from the battery, but we believe this is a fair price to pay. With modern battery technology, the...

  • Page 9: Spark Plug

    The contact gap is 25 thou or 0,6 - 0,7 mm. Different long versions of RCJ-7Y Spark plugs are in existing! The Titan ZG Engines are delivered with an extra short version of the RCJ-7Y spark plug. Only this "Bantam"-Version of the spark plug...
  • Page 10 Instructions Titan ZG 45PCI-HV Fuel tank With a tank of 500 cc, without an intake tube on the carburettor, the Titan ZG 45PCI-HV will run for about twelve minutes on full throttle. But with an intake elbow between the carburettor and engine plus a bellmouth intake tube, so that the induction air is drawn out of the fuselage, a 500 cc tank will give almost twenty minutes at full throttle.

  • Page 11: Fuel Tank Connections

    Instructions Titan ZG 45PCI-HV Fuel tank connections Make two air vents made with fuel tubing, fitted to two single sided nipples in the tanks topside, central at the rear end. These two air vent lines must be led forward over the tank and then down into the fuselage floor at the cooling air outlet of the engine cowling.
  • Page 12 Instructions Titan ZG 45PCI-HV It is the best to leave a little fuel in the tank at all times even when the model is in your home or workshop. This remaining fuel will prevent the carburettor diaphragms from drying out and becoming hard. Partially emptying the tank only when really necessary i.e.
  • Page 13 Instructions Titan ZG 45PCI-HV Mixture afterwards 5 Liter gasoline and 100 ml oil = 50:1, or per liter gasoline 20 ml oil. TAKE GREAT CARE WHEN HANDLING PETROL: USE ONLY THE SPECIAL AIRTIGHT RESERVE CANISTERS NO SMOKING! Propellers We have tested a range of propellers with the 45 and here are the results: Menz “S”...
  • Page 14 Experience has shown that, without doubt, the safest method is to fix the propeller onto the ZG 45PCI-HV with a single large bolt and a wide flange on the prop hub. As long as the bolt is tightened down enough, the prop will not come loose. Should the propeller come loose by normal starting, then the prop bolt was not tightened down sufficiently, or the propeller has shrunk under pressure from the tightening down.
  • Page 15 Instructions Titan ZG 45PCI-HV Changing the propeller hub We have 3 different lengths of propeller hubs. To remove and refit the two socket head screws, securing the propeller hub only requires a propeller to be firmly fixed to the hub to act as a lever.

  • Page 16: Carburettor Settings

    Instructions Titan ZG 45PCI-HV Never remove the butterfly valve from the throttle lever shaft so as to ease the fitting or soldering of a larger lever. The reason is, that the manufacturer spreads the end of the small screw, so that removing this screw damages the threaded hole beyond repair, and re fixing the butterfly valve safely is practically impossible.
  • Page 17 Instructions Titan ZG 45PCI-HV run decidedly rich. A good setting for the low speed needle is 1 1/4. Both needles are more sensitive to adjustment with a manifold fitted. The engine‘s ability to turn larger propellers increases in proportion to the length of the intake ram tube.
  • Page 18 Instructions Titan ZG 45PCI-HV Carburettor Intake Bend If you have very little space under your cowl, a good centimetre can be saved by fitting our aluminium intake bend #4587 between the cylinder and carburettor, so that the complete carburettor is directed rearwards.
  • Page 19 Instructions Titan ZG 45PCI-HV forget the short piece of brass tube for the pump impulse. The rear screw on the cyl- inder flange is difficult to reach, better use a hexagon headed screw for this. Secure with Loctite. The copper bend can break due to vibration, to prevent this, fit a steel supporting strap 10x1 mm between a carburettor and motor mount screw.

  • Page 20: Tuned Pipe

    These power curves are from a test carried out by Dietrich Altenkirch for the magazine “Modell”. They show the values of the old ZG 45SL. The power of the ZG 45PCI -HV with the new standard silencer is more than shown, but the header lengths and rpm are correct also for the ZG 45PCI-HV.
  • Page 21 Instructions Titan ZG 45PCI-HV Stainless steel silencer unit with tuned length header Tuned pipes are very long and far from simple to install in a model‘s fuselage. The stainless steel silencer #5770 is a realistic alternative. Including the header it is only half the length and thereby lighter.

  • Page 22: Starting The Engine

    Instructions Titan ZG 45PCI-HV Starting the engine Due to the Microprocessor battery ignition starting the engine is very easy. Although the starting method is entirely different to what you are possibly used to with the magneto ignition. One important point to begin:...

  • Page 23: Running In The Engine

    Titan ZG 45PCI-HV to a normal position and fly the new engine with very short periods of full throttle and long periods of tickover. You will of course ensure that the mixture setting is not on the lean side.

  • Page 24: Very Important

    Instructions Titan ZG 45PCI-HV Very important: Although the microprocessor ignition unit is perfectly screened, please make a range test with full throttle before the first flight. Use a small propeller to simulate the rpm when the model is in the air. The range difference with the engine shut off and running at full throttle should be minimal.

  • Page 25: Maintenance

    Instructions Titan ZG 45PCI-HV Maintenance The Titan ZG 45PCI-HV requires almost no servicing. If your engine is difficult to start after the hibernation, suck fresh petrol into the carb to loosen the thick oil left after the petrol has evaporated, and let this stand for a few days and you will find the engine will run again without any adjustment of the needle valves.
