    On the ABC a short Time ago.. Not good. Nev

    Better if you are not LSA. It's a stop gap concept anyhow. Nev

    You don't actually see it but can gauge the extent of it from windsocks, the surface of ponds or the crab required at your airspeed. Nev

    Good idea but they aren't cheap. Check no seats have moved in the heads. Nev

    You're NOT wrong. Nev

    The seats are what counts and if the stem has stretched. The valve TEL was developed in the Late 20s do enable more power to be obtained by enabling higher boost or higher compression to be used with out detonation, Rotax Valve material and the seats (Inserted) should be hard enough to last ok..

    Lead works like a flux and if it's not hot enough on the surface it doesn't lubricate the SEATs. It does NOTHING for the valve guides. Nev

    Having the Plane under control is better than fluking a good landing. Most planes have a stated x wind limit. That's only a guide. You have to work much harder with a cross wind and never let the down wind wing get low, or put another way never let the wind get under your into wind wing.. Gusts are an extra hazard. Varying power is a necessity. and be ready to do a go around IF you are not sure and don't muck that up. Nev

    Liquid cooled heads on a Rotax keep the parts too cool to properly handle 100 LL. Uneven build up on the valve SEATS can affect compression. Sometimes that's temporary and will recover when you go back to Mogas. Nev

    THAT gives no certainty or consistent path. All rules should be based on a proven path to improved safety at a justified cost. There are always people who will skimp inspections, fake engine log books and abuse aircraft. (over load and overstress).. The variation of compliance is large and some repairs would not pass muster. That's even happened with the big stuff. Look at Boeing lately.. An acceptance of what IS PRACTICALLY ACHIEVABLE should be in the back of ones mind while we still try to improve the situation 100% is never going to be achieved. Some clarification needs to be done for sure but it needs wisdom and effort and good organising. It's a potentially thankless task, as whatever is done will be criticized by somebody or other who thinks they are hard done by and want's everything for nothing.. The only way anything on a plane can be zero timed is from NEW. Everything is built as Light as is safely possible. It all has a LIFE. Nev

    You've made plenty of use of your plane without flying it and kept safe. Nev

    Some people are still doing it and in the Past, many of them flew to Natfly which in some circumstances could be a pretty EPIC event. Most had 2 stroke power.. RAAus did present themselves as "The NEW GA". I personally felt that was a "step too FAR " but that's just me. . Why duplicate GA? Well, they CASA want to be rid of this" troublesome stuff" and that seems pretty clear.. One court case nearly eliminated the RAAus by it's cost. Who in the top echelon flys 2 stroke powered Basic U/L's? Where you fly from should be a hive of activity so there's a Social side of this as well.. If you are mostly doing it on your own, it maybe is not a lot of fun. This is a bit off topic but a logical development of the inexperienced pilot aspect. The event could be something out of the control of the Pilot also. Never rule out "weird" winds. Nev

    We all get addicted to it. It's expensive and is an unforgiving environment with a lot of annoying paperwork. Always assess IF it's giving you bang for your bucks.. That's permitted. . IF you build, that will probably take all your time and money but I respect those that do.. If you fly, pick your times and circumstances If there's a doubt about something eliminate the doubt where possible. No "she'll be right mate" Nev

    Why does a helicopter taxi like that? It only needs a pad or clearing.. A lot of concentration for nothing. Their WAKE is also dangerous to light aircraft particularly. Nev

    Not as good as that. Nev

    When you are pushing a C-182 around, particularly when turning it, you need steel pipe. Nev

    They never changed,. You still have to get all dimensions right. Nev

    The Mumbo Jumbo is the one to avoid. Nev

    That's how I did it. ESP? Nev

    I explained "Confirm" always relates to some thing, like Confirm LEFT turn onto HDG 320 when it's the long way around. .. Or confirm "clear to take off." or land if you have any doubt. Nev

    The high wing Cessna's stall warning is about 9 Knots above stall. Used to rely on it when limit flying, (using ground effect etc). Heavies have them in some form or other. (SCAT) Good back up when flap settings vary and total weight also and density altitude.. HUD is best of visual options. Nev

    Multiple points on plugs were common prior about 1930. I don't know of any real advantage. They tend to fire on one point only. Line of least resistance and it's more places for a piece of carbon to lodge.. What about heat range. ? Surely with some conditions a slightly hotter or colder plug would be needed. A plug that is not tensioned correctly can run hotter. Plugs overheating gives pre ignition or detonation or an engine running on when switches cut. Nev

    The way gas flowing has developed poppet valves are superior.. Heads warp unevenly though and a seated valve cold may not seal as well when hot. Valve inserts in alloy heads can loosen or hammer further in.. Nev

    Cherry red and quench in oil to harden and temper back to toughen and reduce brittleness. For long thinner items for evenness a nitrate salt bath or a metal alloy that melts at the required temperature. IF you overheat any part of it the Grain of the metal will coarsen and it's ruined for all intents and purposes. If you need to reset the spring subsequently heat that part to the Temper colour. Straw colour on clean steel surface. For any spring mob who makes leaf springs its a normal thing. A better spring is tapered in thickness as well. Lighter and spreads the stress more evenly. Nev

    That's the management bit. Also when you get air into the system you won't get an assured result with a selector change alone.. Nev
