    Depends where the engine failed. He would normally be airborne about half way down the runway so would have had quite a bit of height if the engine stopped near the crosswind turning point for a normal left hand circuit. For anyone attempting a turnback, a turn to the right would be logical as it would keep you in relatively open country away from the hangars, and probably more into the prevailing wind as well (typically E/SE). If the engine had failed early in the takeoff he could probably have got down successfully in the open area where he finished up. Either way, a very sad event for all concerned.

    Or better still let the player decide whether they want to be listed on the public scoreboard once they know what their result was. The public list could include the total number of people who had played so you could get an idea of the interest in the quiz. That way you wouldn’t discourage people from having a go because they don’t want to be identified or possibly embarrassed by getting a low score. That would make the quiz a more effective learning tool, which is the aim after all.

    Hard to see how the XP77 even got to the prototype stage if having the cockpit so far back you could see the undercarriage was considered a good feature in a plane intended to be an interceptor. The whole thing is a collection of bad ideas whichever way you look at it.

    Might be better if all the scores weren’t visible and ranked. No self-respecting aviator wants to look bad.

    Careless reading cost me points. Should have got them all really.

    Whatever is the cheapest and easiest for you is fine with me.

    I practice gliding, stalls and slips on most flights to try and keep reasonably proficient. Another useful exercise is to slow the plane in 5 knot increments down to about 55 kts and practice shallow coordinated turns to get a feel for how it behaves as you get closer to stalling speed. Do this at a safe height of course.

    Like Spitfire, I'm also using a Lightspeed headset (Sierra). Haven't tried adjusting the mic gain yet. I've got an old passive headset so I'll see if that makes a difference.

    Thanks for the suggestions. I’ll have a go. I did have an intermittent loud feedback squeal on transmit that has plagued me ever since the plane was built that I finally traced a few weeks ago to a loose nut on the antenna cable BNC connector that plugs into the back of the radio. Just needed tightening half a turn. I went from readability 2 to readability 4 so that was a good result. The cable was supplied with the kit so it wasn’t one of my dodgy wiring efforts. Now I sound no worse than many other aircraft I hear out there, but I’d really like to get rid of all the noise and have clear transmissions.

    Static as in squelch noise, no pulses. Headsets are not the problem. Intercom is good. Mic jack is isolated from the airframe. Headset jack isn’t - all as per plans for the RV-12. I suspect it may be an earthing problem, but where to start looking?

    Sounds exactly like the static I get on transmit. I’m not sure that it increases with rpm although it probably does. I’ll check next time. All other checks match yours. Also readability 4. No noise with engine off. My radio is a Garmin SL40 and I’ve been trying to find the noise source too. Engine is also a 912ULS. Side tone is matched to volume. All suggestions welcome.

    Would that chuck be at take-off or in the cruise?
  13. rgmwa
    I agree. That’s how I understood it. What’s the next question?

    Being in good company always makes me feel less of a failure. 🙂

    OK, how about this. Since it's a nice day and I'm not in a hurry, have plenty of fuel. and the missus has fallen asleep, just out of curiosity I'll turn 180 deg and backtrack for ten mins, then do another 180 and resume course. If I'm not back at my first turning point after ten minutes, I know the wind has come up and I'm flying into it. Therefore nothing wrong with the aircraft. In that case, I can also time how long it takes me to get back to the starting point, use my map to work out the distance (old school), and figure out the wind speed.

    Ground speed less than expected so need to speed up a bit if I want to stick to the plan.
  17. rgmwa
    Applying Occam’s Razor leads me to conclude that the simplest explanation is “something’s gone wrong”. However as it’s a minor problem and I know where I am, I’ll just add a few more revs to make up for lost time and enjoy the flight.

    Radio a request for an area QNH and check the altimeter setting to see if you're flying at the altitude you think you are.
  19. rgmwa
    You are flying lower than the altimeter is reading so your indicated airspeed is higher than than you expect you TAS to be for your planned altitude so you are slower over the ground than you anticipated.
  20. rgmwa
    Winds have picked up and you've now got a headwind?

    Funny you should say that! When I was about 9 or 10 I’d spend school holidays at a farm owned by family friends in southwestern Victoria. I’d look over the cowyard fence in the early morning as the sun came up and watch the magpies landing in the paddock by the swamp exactly as you describe. I imagined being able to fly like they did. Six decades have passed since those days and I’ve been lucky enough to learn how to fly a plane and also to build one. Since then I’ve done a couple of long trips that have covered a lot of Australia, but I’d still like to cross Bass Strait to Tas one day. I’ve also been lucky enough to have flown in the outback but flying the old Qantas routes through Qld and the NT is still on the bucket list.

    ...and me.

    I’ve always wondered how engineers on Catalinas tolerated the engine noise when they were stuck up on their elevated perch between the two of them. They’ll must all have gone deaf.

    Vans have two RV12 demonstrator aircraft, one with a 912ULS and the other with an iS. They found similar results for fuel consumption to that described in the article.
  25. rgmwa
    If the aircraft weighs 600 kg then as a minimum your two wing tie downs would need to take at least 300 kg each to keep it on the ground. I think I read somewhere that tiedowns should be able to take 500kg.
