    The obvious would be to move the engine back to help with CoG.

    When the rotax back fires, which turbo says is inevitable, the extra manifold volume full of explosive vapour will not just set fire to the K&N filter(s) it could blow the engine off the aircraft. 🤣 On a more serious note, at altitude in very cold air fuel vapour could condense in that large un heated non standard crossover tube. Not sure if that would be a problem. If it ain't broke don't fix it. Doing nothing is free. Fly or fiddle, that's a personal choice.

    Turbo, there is perhaps some differences between race cars built by amateurs running methanol, hot cams, wild ignition timing and a rotax or Lycoming. A lycoming with a straight pipe makes almost no sound due to very mild cam timing and overlap. There is also the possibility that race car engines get turned backwards during a spin, the is would lickly cause fire to come out the wrong place.

    K&N air filters are the standard part in the 13,000+ Van's RV aircraft that are flying around the world. K&N air filters have been fitted to every Rotax 912,915 installation that i have seen. K&N air filters are fitted to many other experimental aircraft, example Glastar. If there was a problem I think we would know about it by now. Over priming, carb leaking, fires that happen while attempting a start will happen regardless of the air filter type. We had one such case at our airport last year, an RV with a K&N air filter, surprisingly there was no damage to the filter itself. I got to see all the damage with the cowl off.

    We will be to scared to fly if we read much more of this.

    Have you tried a GL45 or 45-400 cap, can see pics on Ebay.

    Air in the hydraulic lifters causing a problem is a bit of a myth imo. At every oil change a filter FULL OF AIR is placed on the engine. On lycoming engines, a cylinder change or six requires the hydraulic lifters to be removed and cleaned of all oil so that the DRY TAPPET clearance can be checked and adjusted if necessary with different length push rods. The engine is then started often with a dry oil filter as well. We probably shouldn't be having these discussions on the Zonsen engine thread.

    Also see very little carbon when examining the cut open oil filter paper on Rotax 912,915 engines. I think they have them very well sorted. No carbon stuck to the filter can.

    Have never seen a heat shield for the oil filter on any 912,915 that i have serviced. They all have similar exhaust manifolds.

    Is it a requirement for student pilots to be able to demonstrate a late go round with full flap before being sent solo? Would it be a good idea to limit student pilots to only 20° of flap to make a late go round easier to handle. Less pitch up and no need for flap retraction to get some climb happening.

    Nev, I get that you post things to enhance aviation safety. To suggest that the engine or wind was a factor just muddies the water and detracts from the learning experience. The copy of the cctv i have is quite clear, the camera is tilted at a 16° angle relative to the runway , the Cessnas spinner to tailcone is at a35° angle . Wing angle of incidence would be similar. Yes the aircraft was initially climbing which would have reduced the angle of attack. Once the aircraft stopped climbing critical angle was achieved. 35°-16°=19° That will do it. This video and there are plenty more like it if one goggles "cessna 172 stall crash" should in my opinion be mandatory veiwing for all student pilots.
  12. Thruster88
    The cctv video showing the stall, wing drop, yaw, spin entry, can be found by searching.

    Almost unbelievable for a company that has only been around for a year or two. No patents filed. Time will tell.

    The 18hp mk3 Skycraft Scout only weighed 59kg empty.

    The ATSB has produced some very good educational short videos recently on simple accidents like this one, often within a month, much more value that a report in three years time.

    The Fokker F27 friendship beat it to market.

    I don't see the attraction. The used price on these high end gyros is more than a nice RV. 90knots cruise v 160 for the RV. Turbulence? the impressive climb rate of an RV soon gets one above that if one is going somewhere.

    Tyre Pressure

    Thruster88 replied to Siso's topic in Thruster

    I run used, because they are free and lighter than new, 6.00x6 aircraft tyres. Goodyear flight custom etc because I dislike getting punctures. These are fitted to 6 inch kart wheels. Pressure only needs to be about 8-10 psi. Tyre creep on the wheels is a problem solved by two small self tapping screws each side into the bead.

    xair standard

    Thruster88 commented on BrendAn's classified in Aircraft

    Fast aircraft have to be a lot faster to make a real difference on a long trip. The main advantage with the gazelle would be fuel economy if that is something that concerns you. Fit your HKS turbo to the xair and there would not be much difference in speed, range between the them. I am minding a Skyranger with 100hp rotax in my shed atm, they are a great all-rounder if you can only have one aircraft.

    To end 2025 I got the thruster T85 single out for a fly. Compared to the RV, Beech23 or two seat thruster it seems a little tricky to fly, perhaps I just need to fly it more often. I did see that I had missed a piece in the fallow spray for the 2026 crop.

    Welcome, your machine looks something like an Australian designed Corby starlet. These started life with a vw, many have been retrofited with a Jabiru 2200, more power and lighter. The jabiru may be a better option than the long discontinued KFM.
  23. Thruster88
    Interesting, what are you going to do with it.
  24. Thruster88
    Unfortunately I sold the 1984 mk3 scout i bought new after the first year of flying and moved on to the Thruster.

    Looks like a taildragger doing taildragger things.
