    Rotax 582 with engine mounted radiators as used on Thrusters and trikes etc have twin radiators. Flow is in series. Twins are used by Rotax in this situation because it makes a better package, reliable mounting etc. There are two sizes of radiators used on 582, standard and tropical. The small sizes cools 65hp on very hot days at low airspeed, 35-40knots. The tropical may have enough area for a 100hp 912, they are supplied by Rotax. We recently had a Sling tsi at the shop. The way the coolers were mounted was pretty neat. They just clip to the cowling, no air leaks, reduced vibration on the radiator. To get maximum efficiency you will need cowl flaps. It is a simple way to reduce cooling drag when you don't need maximum cooling.

    The hole is 47 feet and the wing span of an A-4 is 28 feet. It could have been done with a high power telephoto lens, aircraft is behind pulling up over the rock. No photo shop required.

    A diagram of the complete fuel system would be helpful.

    Is that a crack in the top right corner?

    I wonder if Mike may have tuned that Rotax 582 2 stroke to produce a lot more than the stock 65hp @6500rpm. There were plenty of knowledgeable 2 stroke tuners at that time.

    Most Van's aircraft do not have wing root fillets including the later models like the RV14. Have seen some on a RV4, if they made any difference they would be more common. If they made a 5 knot difference they would be on every RV.

    Rotax make all the engines for BRP products plus kart, aircraft and some OEM motorcycles.

    We all thought covid would tank the used aircraft market. Quite the opposite happened. One thing to remember, they are not making anymore used aircraft, the used supply declines each year due accidents, maintenance issues etc. New prices regardless of the category are very high. Go to the Van's store and price all the components for a RV7, the already flying RVs are excellent value. Supply and demand. Current high prices may bring more used aircraft to the market, plane sales Australia has increased from the usual 24 pages to around 32 in recent times.

    I have always watched the aircraft market, there are no good cheap aircraft. In 1996 I really wanted a Cessna 172M, they were then about 40k, I settled for a 25k Musketeer that I still have. Today that same 172M is worth 100k.

    One wing has detached. I think it would be difficult to do this after landing a Cirrus without hitting anything. Perhaps a pre landing stall.

    This could be the first loss of trust in an electric aircraft in oz. The electric version of fuel starvation. 11/3/2023 Lilydale VIC Pipistrel Alpha Pipistrel/Emrax EEM60MVLC (Electric) STATUS: Under review OCCURRENCE DETAILS SUBMITTED TO RAAUS: the aircraft was conducting circuit o... STATUS: Under review OCCURRENCE DETAILS SUBMITTED TO RAAUS: the aircraft was conducting circuit operations on when, on the climb of the 4th circuit at 600ft AGL, an instrument display warning appeared 'Power control lever failure' which resulted in complete loss of power. The pilot pitched for a glide and a turn back, attempted a reboot cycle of all switches off, pulled the power control breaker, powered on all systems in sequence but the same warning appeared. They repeated this one more time, but power control was not restored. The pilot didn't feel they had enough height and speed to reach the aerodrome/runway, so made an uneventful emergency landing in a field to the immediate North of the runway.

    Cost would be similar at Cowra aero club. We probably are not charging enough to allow for aircraft replacement in future. Flying training is not a gold mine.

    This accident certainly had it all in the lead up. The sad part is it was just a simple stall, often the case in fatal General Aviation accidents. We can safely manoeuvre our aircraft close to the ground with or without engine power.

    Puting an aircraft on and off the trailer four times, plus assembly, to go flying will get old very quickly. Rent some hangar space or join an aero club. Aero clubs are still the cheapest way to fly up to 50 hours a year.

    As long as you understand that pulling back on the stick puts more load on the wing and pushing forward puts less load on the wing you will be fine.😁

    I just had a look, there is only 112 places remaining for an ONLINE seminar. How is this possible, no bandwidth?

    Imagine you are inbound to this airport. How many radio calls would it take to get situational awareness versus what can be seen in a few seconds on a screen. The future is here, we just all have to get on board.

    Jimmy's world is a great channel.

    144 ktas very impressive. Faster than those euro ones ay. What rpm and manifold pressure to get that speed?
  21. Thruster88
    24 registration so factory built. We would assume it was done correctly.

    A good ear at the engine breather, exhaust or intake will identify the source of a cylinder leak.
  23. Thruster88
    Most maintenance organisations will have a master orifice tool. This allows checking against a known leakage.
  24. Thruster88
    Reflexing the ailerons up should have minimal effect on the differential ratio. Any change in the differential ratio will depend on where the ratio is produced, at the bell crank or at the aileron connection. If the aileron pushrod connection and the aileron pivot are at 90° to the cord in the neutral position then no change to ratio. One advantage of reflexing ailerons up and maybe even reducing flap up reflex could be better stall behaviour. By reflexing only flaps up you are effectively reducing the wing wash out. I would seek the advice of the manufacturer.

    I would not buy that. The second pressure gauge should have the same markings as the input pressure gauge. We dont use % in aviation, it is always just a number eg 65 over 80. Manufacturers will specify a minimum number. The one RFguy linked above is the one to get. It has two identical gauges and the correct orifice.
