  1. Servo for CS.pdf I have been using CS propeller on Rotax for the last 8 years. Very satisfied with the result. Maintains propeller speed within 100 revs over the range of 4800 to 5500 engine revs. Operated by pushrod by servo motor mounted on top of gearbox. Push for coarse, spring loaded for fine just in case anything goes wrong. Moves blades through a 10 degree range. Can also be used as fixed in flight adjustable by the flick of a switch if required for training. If you require any further info PM me. John.
  2. That support bracket is on TL-Ultralight aircraft. It continues down to incorporate a drip tray. Makes very stable carbies.
  3. You check the Bing floats by weighing them. 3-4 grams is ok, over 5 grams replace.
  4. The TL Sting S4 has a factory built in roll bar just behind the forward opening bubble canopy.
  5. David is well aware of the quality and capability of the TL 3000 Sirius.

    Rotax 912

    Every 912ULS uses the same amount of fuel to produce the same horsepower if setup to spec. You need manifold pressure readings to know what is going on. Rotax recommend cruise at not below 5000 rpm and idle not below 2000. John.
  7. I use the Ping running on a portable USB power supply.
  8. The better BRS are fully deployed in 3 seconds and are shot well clear of the plane to avoid tangles. Believe it or not they can be deployed down to 30 meters ( 100 feet ). I wouldn't recommend that. Having worn a pilot chute for many years I know it is very hard to exit a plane in an unusual attitude. John.
  9. Obviously made from broken hay rake tines - spring steel. John.
  10. MH134 took off with 3 pilots up front, they must have taken off when the far fence appeared. Four pitot covers were left on. Three for air speed and one for altitude. Thet also did a heavy landing and the A330 was not moved for some time. Pitot covers have been mandatory in Brisbane because of a wasp problem. In the case of qantas the ground engineers remove the covers with a long pole then take them up to the cockpit where they are signed for before take off. John.
  11. I have a friend who flies behind a 6 cyl. Jabiru and does not have any overheating problems if he avoids a certain (narrow) rev range. Sorry can't remember that rev range but could find out. John.
  12. I will have another look later, may have been too close to Sydney.
