    Using uv smooth and epoxy primer
    I'm about to start painting and I'm looking at using Polyfiber's Superfill, UV Smooth, and Expoxy primer on my fiberglass parts.
    Any cautionary tales, techniques or lessons learned with these products that you could pass on to me would be appreciated!

    Thanks,
    Ron

    This is a great upgrade if you fly primarily off pavement and are still using the old Maule style hard rubber tailwheel.

    Thanks for the heads up. This is not for from me. I am planning to attend at least for a few hours. My leash will be pretty short as I will have just returned from 10 days at Osh.

    Makes sense. Which is more important? If I only had a cht, I wouldnt be sweating, but watching my water temps press 180, I'm hot!

    The cylinder head temp uses the ring probe under the spark plug. No water right there and that's where the big fire is.. So the head temp at the plug is higher than water temp.

    Water temp is 180 max from rotax, but I have seen it published that momentary temps of 200 are ok.

    Water temps and CHT temps
    Why is the water temp range so much lower than the CHT "green arc"?

    Water temps should be 175 max

    CHT is 230-270 with 300 max.

    My water temps and CHT are nearly equal which I expect them to be. But my water temps are on the high side, but my CHT is not even close to the "green arc" of 230-270???

    More power = more heat = more water/air flow, radiators work better with low pressure cowlings, not high pressure to radiators!

    I would have gone for the grass too! 
     
    It is pretty sobering when you start reading about accidents.  We have a huge rash of them every year here at hunting season, partly due to bad weather and bad decision making (yeah, I have never been guilty of that...) but more due to the fact that guys have planes that they only fly 10 or 15 hours a year during hunting season and they sit in the hangar the rest of the year... so we have pilots that are not proficient, bad weather, and planes hauling loads at gross (most of the time over gross).  
     
    I feel rusty when I dont fly for a month and I wont take any passengers up till I have done a few turns around the pattern just to make sure the plane and me is up to speed...  This does not mean I wont have an issue that I have to deal with, but it makes me feel better flying the plane empty and gives the engine an opportunity to tell me if something is wrong with it.  We all know what a difference a passenger makes on the performance of the plane, I would rather try to make the runway with just me in it than to know I wont make the runway with a passenger.

    I had cut the bottom lip off my cowling when I was using the belly radiator.  When I went to the incowl radiators like you have I had to glass that lip back on and I had to put baffles around the radiators to keep all airflow going straight through the radiators.  since I have done that I have not gotten it to break 180 in a hard extended climb.
     
    I would also check that tack with an optical hobby tach on the prop (then do the math for your reduction on the gear box) or spent 45 bucks on a tiny tach,  The Analog tachs are about like the skidoo dream o meters they put in the dash on snowmachines that tell you your going 125 when in reality, on radar, you lucky to hit 95 MPH. 
     
    Your ETGS are really low and will lead to carbon build up as well as over loading the engine.  I dont think your getting the RPM that you think you are.  What are your EGTS in cruise?  you really need to get them up around 1100 to help burn that carbon out.
     
    What do your plugs look like?  EGTS have errors in them and are only to be trusted to show a "trend"  You plug color is the life line on a 2 stroke and should be what you judge your EGT temps against.  By that, I mean that if you are getting a nice tan colored plug with no fouling, but your EGTS are only showing 900 or 1000, then use that as you bench mark on the EGTS and keep an eye on them from there if they start showing an up or down trend to let you know something is changing in the mixture or loading of the engine.
     
    What RPM are you getting on take off and climb out, and what are you hitting at straight and level wide open throttle?

    Just watched Fox News live broadcast as a Beech Bonanza couldn't get one of main gears down - he flew off fuel while trying to get it down, but finally brought all gear up and made a perfect belly landing on concrete - all 4 got out quickly, and no fire - perfect video from side of runway.   I believe I would have chosen the grass, but that was his call.....

    Get a tiny tach. Your tach is wrong. Guaranteed.

    I agree with the airfow comments.  If you look at that big muffler sticking out the bottom of the cowling the top half is actually deflecting air up into the bottom cowling.  I would try a temorary piece of aluminum attatched to the bottom cowling to bottom of muffler and add a lip around the rest of thr bottom cowling opening.  You can put huge radiators on it but if the air does not flow through them they will still not cool the water/antifreeze.

    Thnx Bryce, good info. Used to be Dad and GrandDad would McGuyver or Rube Goldberg something six ways to Sunday before retiring a part. In this disposable world of ours, we have now reached the point where we toss a $15 metal part for want of a few pennies worth of rubber. G'Dad would be shaking his head!

    With wing area nearly twice as much as an Avid, if you build it light, it should really be a good slow flyer, and stall should be really slow.
    What was really a shock to me, was the differences in landing gears, from the strong-looking gear on the original GT, to the weak-looking tiny gear legs on the newer EZ.

    This one had a 618 in it originally.  The builder is still here in our EAA chapter.  He evidently crashed it during the test phase and then sold it and it has been sitting ever since.  Too bad the guy that had it didn't store it better, it would make the rebuild a lot easier.  It is good that the company is still in existance so hopefully parts should still be available.  The main parts missing are the landing gear & prop which were wiped out on the crash and engine and instruments were sold separately.  Will have to let Jeff decide what to power it with.  It does have the 618 engine mount so would probably work on a 582 as well (guessing).  It is dimensionally a pretty big plane for the 582 though.
