  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. 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.

     

     

  3. 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.

  4. 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.

  5. 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.

  6. Last weekend, 18 & 19 May Colac Airfield was raided and six hangers were broken into. Locks just cut off. Not sure of value but many thousand dollars worth of fuel and equipment. Plus damage to aircraft.

     

    Some of the items STOLEN

     

    Aircraft Parts, Equipment and Accessories.

     

    Avgas, aircraft engine oil, many other parts.

     

    Aircraft damaged.

     

    Items stolen include:

     

    Multiple tool boxes and tool bags.

     

    Aviation tools

     

    Avgas, siphoned, and in jerry cans

     

    Jerry Cans, red plastic type

     

    Bulk aviation oil in 20 litre jerry cans

     

    Aviation Headsets, approx. six sets

     

    GPS devices

     

    Aviation Radios

     

    Gas welding kit in Chrome style case

     

    9kg gas bottle

     

    ARB Winch

     

    HF Radio

     

    UHF Radios

     

    Piranha Dual Battery System

     

    4wd accessories

     

    High Pressure water pump and hp hose

     

    Space Cases, Blue

     

    Air Compressor

     

    Spray painting equipment

     

    Country airfields seem to be a target and I believe Wangaratta and Bairnsdale  have also been victims.

     

     

  7. Welcome to the presence of TL-Ultralights on the forum. Anyone particularly TL owners and pilots is welcome to add comments and photos relating to TL aircraft.

  8. My plan is to disarm the rockets and have them disposed of legally then freight the chute as normal freight to the manufacturer for repack and sent back with new rocket as dangerous goods.

     

    I have a friend who has dangerous goods license. The better the volume the better the cost.

     

    John.

     

     

  9. Apart from the valve and plug fouling mentioned above the issue with using Avgas in Rotax is the lead buildup in the gear box which affects the clutch. You should change oil and filter every 25 hours if using Avgas. The gearbox needs to be serviced at 600 hours if using Avgas and Rotax recommends using Avgas no more than 30% of time. Better to use unleaded.

     

    The problem with using Aeroshell semi synthetic oil in Rotax is that it is not suitable for the gearbox and clutch.

  10. Hi RR, your estimations on fiberglass aircraft are not accurate. I have done surveys and life extensions on fiberglass gliders that are over 40 years old and some have flown 9000 hours.

     

    Some of the very early one had problems with gel coat but the new technology is very much better. Like any aircraft they are better kept in a hanger. Some of the new composites are not life limited.

     

    I also know of many metal aircraft that have been grounded because of fatigue.

     

    Happy flying, John.

  11. BirdDog from your description I am guessing your Woodcomp Prop is a SR3000. If so I can send you the operators manual (PDF) if you don't have it.

     

    Pitch stop adjustment is critical to stop over revving in fine or propeller stall flutter in full coarse and full power. John.
