    Painting with latex house paint

    I have decided to use a quality latex house paint on my airplane. If any of you have used this for yours did you use any fabric sealer or primer first or just start applying coats of paint?

    Rotax 503 Question

    I am putting a rotax 503 on my airplane in the tractor configuration. could i get away with removing the shroud and fan to keep it cool. I don't plan to tightly cowl it. Just wondering if free air would be enough for it with the prop wash blowing over it?

    No Excuse Now

    Is one gallon worth it?

    I have a 6 gallon boat tank in the fuselage of the ultra-piet that I'm building. I am putting a rotax 503 on the front of it so I'm guessing a fuel burn between 3 and 4 gallons an hour. that means 6 gallons will give me around 1 1/2 to 1 3/4 hours. I don't have much room for more fuel but could...

    I got around to digging the rotax out and it appears to be meant for a snow machine. Can this be made to work on an airplane and if so what parts will i need?

    Varnish

    My plans call for baltic birch or finnish birch, I see Aircraft Spruce has finnish birch and domestic birch both meeting aircraft specs, the domestic birch being cheeper, can domestic be used or is finnish birch that much better? Also a local lumber yard (not a big box) has baltic birch in the 5...
