    I originally had the nose tank so I don't currently have a dash to meet up to so that's no problem I can just make one that goes where ever it needs to. just want to know if I will be introducing any issues by not having the cowl fair up as it transitions into the lexan, I can't see any reason not to other than maybe keeping it clean? I have seen other cowls like this with just a hole hadn't noticed the cover on your cowling I think I will do the same, thanks for the hint.

    The PC 680 should do fine for your suby. It stars 032 and 0470 engines all day long up here in the winter. Most of the guys that have gone to the firewall mounted batteries in C-180/185 use the 680 as well as 90% of the cub drivers I know up here.

    I flew a PA-12 last week that has a 680 in it and did not have any issues starting it.

    I was hoping and waiting to read what some more knowledeable person might write, like SUBERAVID in Alaska - Since none have written so far, my best guess is the Odessey 680 or larger - depends on where you are putting it, and how much weight you want too.
    Look up this one if you dont get a better answer.

    If it is like mine, if you cut the flare off it wont cover up where the dash and the windshield meet. I too have the rubber moulding around mine to keep the rain and crap out. On mine, they must have had the same issues as you because they cut out a hole in the front of the cowling for the front spark plugs and make a small aluminum fairing that they riveted in place to cover the hole. I will look and see if I have any pics of it.

    Here is the link to mine showing the bump in the front of the cowling

    Cowl to windshiled fit problem
    So i checked the cowl with the spinner. No good the build manual says the cowl should sit 3/8" above the spinner. As it was from either the original builder or where the factory drilled the holes it sat about 1" below the spinner. To fix this I Hysoled the holes and sanded smooth then started over, this cowl is poorly designed to say the least. I was able to get it to be just barley above the spinner but not the 3/8" called for in the book it looks good though so I settled on it. Problem now is in order to raise it up this much it now interferes with the front spark plug on the bottom- solution cut a hole for the spark plug clearance not too much of a problem. Next problem now is its too close to the windshield and I have to cut it back to make room for the windshield to go into. I'm thinking just cut it back and put some sort of rubber molding around the edge where it contacts the lexan. Is this enough or do I need to do some fiberglass work and make it fair back up like it was. I have never worked with fiberglass before and was hoping not to have to do too much work to this cowling as I would like to replace it at some point anyways. I took a pic of the problem but forgot to upload it off of the camera so I'm borrowing Joey's pic just so you can see what type of cowl I'm working with. Second pic is one I found that used rubber molding on the edge sorta what I have in mind only without the fiared up part. What do you guys think?

    Randy,
    My books on using the Chevy AC condensors says to have AN 3/4 inch fittings welded to them and use AN fittings on hoses.
    I dont see why you couldnt use push-on fittings instead. That would be cheaper, and probably lighter yet.
    Used condensors At $5 each at junkyards - Lighter and makes $ense. Condensors cannot be repaired for AC use because of the extremely high pressures in the AC system.
    I think that Reinhard used these on the first Stratus engines.

    SuberAvid Randy, just wrote in another post that both of his are a Facet - He has the Stratus with dual bing carbs. About 4 pounds of pressure.
    One important thing he said was that they had check-valves in them to let the fuel flow from the tank if the pump is not working and not backwards from the engine or other pump.

    Ed,

    What radiator do you have for it? I am looking for a set of MK IV radiators so I can get rid of my belly mount radiator. I want to put a big cargo pod under there instead of the radiator... of course, this is assuing that the wind storm does take care of the plane for me in the next few days..

    Think I already have one - Got a 532 with 80 hours, gauges, rad, mount, everything, and cant get an offer.
    Need to get a bigger boat for the weight of it.

    All it says is Aerobat - no model listed - no weights. Only 4 pages. No clue if there was an Aerobat Magnum - but something may be in the builders manual - I havent looked for it.

    This for a Aerobat version of the Magnum? Or Avid Flyer? I have a copy of the factory supplied 'Avid Aerobat Manual' for Avid Flyer. Not dated but I believe this was distributed with the C model Aerobat. It gives entry speeds and basic techniques for how to perform Loops, Barrel Rolls, Snap Rolls, Wing Overs and Spins.

    Thanks for the pump info. There are several Facet pumps in Spruce - I have the number of the one Dave complained about, and there is a larger, round one that has several check-valve options too.
    Do the tiny holes work - Dont have a clue - just guessing - Maybe Mr. Piper thought so? Probably wont put them on mine, but cant see that they hurt anything.

    My 532 flew just fine with a belly rad 1/2 the size of my VW Rabbit rad.
    Sorry, thought you had a Soob, and these need more cooling. If you decide to ditch the cheek rads, I would be interested.

  20. EDMO added a post in a topic fuel pump   

    Depends on what Carb you have. Maybe you have a suction leak in lines or pump? Maybe you can rebuild your pump?
    Mine has a Holly 5200 - most Holly and Carter carbs take 2 to 6 pounds of fuel pressure. I dont know about the Jap carbs.
    My builder told me not to use Facet, but others do. Automotive Accessories makes a pump, but do not know model.
    Some, like Airdale, on the Stratus with Jap dual carbs, used a 1970s or 80s Ford pickup 6 cyl fuel pump.
    Maybe something similiar, if you have a Jap or American carb?
    I havent bought mine yet. Randy "Suberavid" has two of some kind on his Stratus - trying to find out what kind.

  21. EDMO added a post in a topic Sandblast, wire brush, or soda blast ????   

    The "aviation guys" are probably used to working on spam cans. Glass beading is used on aluminum. Light blasting will not hurt your 4130 steel tubes, or hide defects.
    Enjoy the offer of approx $300 for blasting your fuselage - By the time you finished doing it yourself, you would give $1000 NOT to have to do it again!!(been there and done that)
    Get some paint on it asap and dont handle it with bare hands before painting.
    Dont use gray primer because you cant see where you have missed spots.

    Travis,
    FYI: My Magnum manual has an additional insert that describes all of the maneuvers for the Aerobat. I havent read it - Guess it is available from Avid, or was?
    I just try to fly from A to B, and try to keep it between the telephone poles!

    Doug,
    I agree with you 100% - No one should go "into the unknown" without some kind of logic, and the kit manufacturers have surely protected themselves and reputations by being cautious and having a large safety factor, and lots of stress tests.
    To add to what you said about Avid, we also have the Avid clones and mods info to look at, aka Kitfox, Magnum and Airdale, so it is easy to make comparisons on GW, structures, wings, etc.
    Then, there are the Aerobatics, which most of us dont even consider because we do not do them.
    A bigger factor in most cases would be hard landings or turbulance with a max load - then, we get into that old bugaboo that some like to agrue about where light wing loading is more dangerous than heavy....I dont even want to get into that discussion again.
    Best thing I can say for myself is: Build it strong - Fly it well - enjoy the view.

  24. Tree top pilot added a post in a topic Sandblast, wire brush, or soda blast ????   

    After some discussion with the guys at Timco aviation , they said it was becoming an alternative to media and glass bead blasting in some cases. They warned me of sandblasting will change the hardness of the outside of the tubes...like shot peening and making it harder to inspect weldments. He said it abraided the metal and would hide things from the eye. They said the important issue was the removal of all salts and application of rust inhibitor.Hold tight Also spoke with a local gent that will come to my door and take care of the job. His fee is $140 / Hr. He stated that the job would probably take 1 to 2 hours to complete. I think he will be coming out this weekend.....He blasts the parts dry...and then pressure washes the salts away and applies the rust inhiting agent at the same shot. He said he would use the compressor to blow everything dry at no extra charge. Said he finished a PA-18 last month. He knows airplanes a good bit too.
