  1. Telco Antennas sell a little gadget called the RFI TLA4100 - it is a sharkfin mobile cellular band antenna that they have fitted to the underside of RFDS aircraft with some successI'm thinking of getting one for the Drifter and hooking it up to a Netgear Nighthawk M1 modem/router...wotcha think ????? oh yeah, only $189 AUD - bargain !!!

    RFI TLA4100 Looks good. I was wondering if anyone had fitted an antenna. Never seen a thread or topic on it....

     

     

  2. I’ve noticed that my iPad has terrible reception for mobile data compared to my iPhone. My dad seems to have the same experience.It’s annoying because things like weather data or traffic often does not function on OzRunways on my iPad, but is fine on my iPhone.

    My iPad is about a year or so older than my iPhone, so maybe that makes a difference, but does anyone else have comment on this?

     

    Thanks,

    I think you'll find it is to do with what frequencies your phone/tablet accepts and what system your on (telstra or optus/vodaphone).

     

    Telstra shut down the 2G network and some older phones failed to work when out of the 4G/3G areas.

     

    They bring in new frequencies for the latest, fastest speeds and slowly make old systems redundant. One of the main reasons people upgrade.

     

    Also different countries use different frequencies, so you need to be careful with internet/overseas purchases.

     

    Google your device and find out what frequencies in receives and google your provider to see what they transmit on.

     

    Your device, at that age (5yrs), may not be 4G/4GLTE capable?

     

    So if a 3G/2G tablet you will only get 3G.... Your phone maybe picking up 4G.

     

    5 years is a long time unfortunately.

  3. The HGFA will always have a focus on weight-shift and minimum aircraft - we are seeing growth in Powered paragliding - both foot-launched and wheel-based, as well as a renewed growth in light single-seat powered hang gliders eg Airborne T-liteHGFA is not seeking an increase in the max weight of CAO 95.32, is not seeking access to controlled airspace/GAAP airports, instead it seems our members are looking for fun flying at minimal costs, usually from dirt strip (no fee, no AVID, no ASIC) airports.

    I like all that and I'm keen on Powered paragliding but as an RAA member and 3 axis owner, I can't bring myself to join another organization and and go through the full training syllabus.....

     

    Is there really that much difference between aerochute/powered parachute and a powered paraglider?

     

     

  4. Original post 2011. .....

     

    Rotax spec 80 hp UL engine min 91 RON fuel.

     

    100 Hp ULS min 95 RON fuel....... many prefer 98 incase the fuel octane degrades. RAA produced a paper indicating fuel octane does degrade in vented tanks over time and states some solutions to the problem.

     

    Other countries use different octane rating standards. The USA uses MON. The numbers tend to be slightly lower than our RON rating.

     

    91 in the usa maybe fine for a ULS but putting 91 in a ULS here is a no no....

  5. That plug cap is for fitting over the round "nut", not for going on the thread by the looks?

     

    The thread on a plug is quite small, that looks too big. Maybe just the pic.....

     

    The 582 plugs are available as "solid" with a fixed non-removable head or with a screw on nut type.

     

    Rotax do specify the "solid" types for the 582 as there is a risk of the nuts unscrewing in flight they say....

  6. We need more younger instructors coming through because there is a looming shortage of experienced instructors in both GA & RAAus. So far, in 12 years of operating this school, I've had one - yes 1, enquiry from an SI about doing some instruction at the school. And in that time, only 2 enquiries about doing an instructor rating. RAAus might need to look into just where the next generation of instructors is coming from? happy days,

    There was talk at the RAA meeting at Whitegum farm last year (with pres & ceo) about the age and future of instructors.

     

    There was a plan of allowing experienced pilots to do some sort of limited tif with potential students. Under cfi control I would imagine.

     

    This allowed pilots to get a taste of instructing and hopefully move them forward in that direction.

     

    Gordon at white gum would have more info....

  7. The basic engine doesn't justify being developed to this extent .They (Rotax) should have designed a new motor from scratch. This is gilding the lily too much. Nev

    Yes, I agree, but you wouldn't be leveraging on the marketability of the most successful light aviation engine ever.

     

    And the parts compatability from the ULS means more profit.

     

    I can only hope this engine gives someone like Honda some interest in manufacturing an engine.

     

    With Honda's engine data, engineering history and manufacturing capability, a junior engineer should be able to knock one up in a couple of months and beat the 915 in every way, including price.... (only half joking)

     

    915 is still a pushrod engine FFS...

     

     

  8. A quick and easy way to test the strength of the starting system.

     

    Remove one plug on each cyl and turn over with mags off. Record rpm. This gives an unloaded (no compression) test.

     

    Re fit plugs and test again.

     

    If rpm's are the same, it means your system is strong as it can crank the same rpm's loaded as unloaded.

     

    I'm personally getting about 420-440 rpm in both situations, so pretty happy about that. 912 ULS (100 hp)

  9. To open yet another debate I also agree with being able to turn a motor off completely, while overhead an airstrip and carry out a practise forced landing all the way to touchdown. This should only be done with a CFI on board and at a suitable strip that has safe options, at a time when it will not affect other traffic. I have done this and believe it is worthwhile to experience it. Having done it in a controlled & supervised fashion will help reduce the shock & possible panic when it eventually happens for real.

    I 100% agree with this and have done it. I think being unfamiliar with your aircraft in a true glide, the shock and panic as you state, plays a major factor in all these fatalities which seem to be in survivable situations.

     

    I started turning the engine off at a fair height and just consentrated on maintaining good glide speed, managing energy, going through checks and re-start procedures. Then re-starting and climbing back to height. Obviously all this over a suitable strip.

     

    After a while you realise that you have TIME. The aircraft still flies relatively normally at glide. You are able to make unflustered conscious decisions rather than panicked, potentially wrong decisions under perceived pressure.

  10. Yep...he didnt stick the nose down...just run out of speed...also probably hauled it off and started climbing at minima also he was 2 up so made it even worse...then of course he has pulled back on the stick. No inertia...I alway climb out at 60kts or a little more. Gives you some extra breathing space if the engine quits to get the nose down and maintain some speed

    First thing I was taught in RAA was "immediate nose down, maintain airspeed" and I think in all BFR"s this has been checked.

     

    I was at a club safety meeting a few years ago and the (GA) CFI stood up and said to all and sundry "What's the first thing you do on engine failure?" .

     

    Answer "Use momentum to climb".......

     

    I can really see problems with GA pilots coming over to RAA aircraft....

  11. CASA would Luv to ground all GA A/C & deal with the RPT guys, far safer. Remember CASA's Moto......safe skies are M/T skies

     

    Have you got any evidence of that Gravity, or is that just what you've picked up from other sites?

    After my attendance of casa safety seminars over the last couple of years, I see nothing dissagree with in Gravity's comments.

     

    What's funny or ironic, is that the majority of the attendee's are one form or another of recreational pilot actively being pro-active about safety, yet I think there is a strong distain from casa about non-proffesional pilots....
