  1. nlappos added a post in a topic weight and balance Model C vs. Mk IV   

    A Rotax 670 has 91 hp, and weighs about 10 to 15 pounds more than a 582 (including a belly radiator), fits in the same mount and drops in easily. Also, the Rotax Rick zero time 670 is about $3600 with a used 582 as a core to Rick.
    My 670 works like a charm, and really moves my Mk IV.

    For my single caliper Avid MKIV, I tried everything, even the power re-fill systems that blast clean fluid up from the calipers to the reservior. The ONLY thing that works for me, and it really works, is grandpa's old fashioned tube in the glass jar method, were the tube, pushed over the bleed fitting, is under fluid in a jar. Then you open the bleed while pushing on the brakes and the bubbles come out. It works well, costs nothing, and gets the brakes to feel solid. 
    I think is works best because the air-trapping corners in the claiper as best cleaned out that way.

    The main gear itself comes aft, so it will shift the empty CG aft a bit (but not very much since the arm is so short).

    cost, yes. The single is about $270 list and the double is over $480, as well the single is lighter (a big deal when the aft CG component is accounted for). My pneumatic tail tire is swell, and the extra couple of hundred bought a transponder (on eBay!)

    Check this Rotax Installation manual out, page 18-4 and 18-5:  https://m.cps-parts.com/cps/pdf/d00287.pdf
    Basically 170 watts at 6000 rpm, or a 16 amp fuse at 12 V DC. The rectifier is very efficient, so AC Watts = DC Watts

    A new double spring is a great answer. Try Wassau Spring, they are responsive and have done several of ours. Just search on this site for their info.
    while at it, I recommend the pneumatic 8” Matco single arm tail wheel over your Maul. Smoother landings and no noise taxiing.

    branded Macralon, marked by the manufacturer, is unknown? I can read, I'll send you a link to the alphabet, so you can figure it out. And it is abrasion resistant, vs the regular that you list, at a fair price. I have no idea why some folks think Ebay is a pejorative. Half my plane comes from Ebay.

    I contacted the guy in the ebay ad listed above, he said he could provide a 48x60 piece of 1/16" abrasion resistant polycarbonate for $210. I think I will trigger that in the spring to do my windshield.

    I have found the specs for the polycarbonate materials, and I think they each have several variants for different applications, including abrasion resistance and non-static electric. Otherwise, I bet the various brands are virtually identical.
    The abrasion resistant types are priced high, they seem to go for over $300 per 4x8 sheet, while most sources sell plain vanilla poly for about $50 a sheet. I am doing my windshield in the spring, I think I will buy a half sheet of the abrasion resistant stuff. I can provide the links I found if anyone is interested.

    After some on line searching, I see that the Makrolon is just a brand name for a Bayer polycarbonate, the Lexan is the brand name for a Saudi company that makes their brand of polycarbonate. Both make "abrasion resistant" versions. I will try to find some on the web.

    I find that even when I keep the doors closed, junk finds its way in. I am mystified.

    Easy way to see is to make a scale model "bird farm" with an outline of the hangar and a scaled cut-out shape of each airplane. With a 30' span, high wing. 20' long Avid, and another 24' span high wing that is 13 feet long I bet they will not fit in a 36' without a lot of shuffling. But the bird farm will tell you. Good Luck!
