    Painting with latex house paint

    My Eindecker has Behr latex. No primer, just rolled on the paint.

    Peter does it again

    What happens when you experiment and iterate ideas? Often you find yourself going toward more efficient and practical designs....which also tends to be what others have found to work.

    Peter does it again

    I guess you took a nap and Peter already built a new plane! Look at the video in post #1 and see his latest creation.

    Peter does it again

    I found that having two axis controls did not limit my flying anymore than that ultralight planes aren't suitable for high winds anyway. The main issue is cross wind...two axis planes have to crab into a cross wind and often touchdown in a crab. For a tricycle gear (Quicksilver or Ercoupe)...

    Peter does it again

    I like that he chose to go with 2 axis control. I flew a Quicksilver MX for several years and really like the way it handled. This is sort of a 21st century Skypup.

    503UL DCDI, Static RPM Expectations

    Until you get the plane in the air you won't know if the rpm and carb mixture (ie, EGT) are correct or not. At full throttle in level flight your max rpm should be less than 6600 and your max EGT should be 1050-1100 F. Adding pitch to a prop normally decreases rpm and EGT....reducing pitch...

    503UL DCDI, Static RPM Expectations

    Your numbers are pretty close to ideal. I always tried to set my static rpm at 6200. The engine would usually turn between 6500-6600 in flight at max rpm.

    What is an affordable ultralight?

    No. More like 20 mph and 100 miles per tank full.

    What is an affordable ultralight?

    You bet it could. I once did some design plans for a Flitzer bipe using a combination of Baslee and Texas Parasol construction techniques. I'll bet it would be a nice flyer on a VW engine.

    What is an affordable ultralight?

    Yes, a Baslee airplane. Actually, it's a very nice flying airplane if built and flown within the design limits. The original design has a 23 foot span wing with 92 sq. ft of area and a design max gross weight of 450 lbs. Build the plane at 250 and you've got a 200 lb payload to work with...

    Affordable Flynano concept

    If 48 is anywhere close to stall speed then maneuvering will require some care. In a 45 degree bank the stall speed will increase significantly. Less than 20 mph between stall and cruise is a tight margin.

    What is an affordable ultralight?

    Some of my greatest fun involved having to climb to get over barbed wire fences. Flying low in an ultralight is reasonably safe given attention to certain factors. These include being careful of wires/obstacles, keeping a good margin of speed above stall, avoiding maneuvers that might get you...

    What is an affordable ultralight?

    The plane does have top wires. Wings are two piece that just plug into sockets in the fuselage. No top wires and the wings just fall to the ground.

    What is an affordable ultralight?

    Adding a roll over structure isn't really feasible....by the time it was safe enough the weight and drag would be significant and the plane would not be a "replica" any longer. The kingpost is there but it's lower than the top of my head. This thing has tried to bite me a couple of times so I...

    Affordable Flynano concept

    An aircraft is said to have positive stagger, or simply stagger, when the upper wing is positioned forward of the lower (bottom) wing,[1] Examples include the de Havilland Tiger Moth or Stearman. Conversely, an aeroplane is said to have negative stagger in unusual cases where the upper wing is...

    What is an affordable ultralight?

    We are in agreement...what you fly dictates where and how you fly. My current plane worries me more than any I've ever flown in regard to making a safe forced landing. The highest point in my plane is my head. In a roll over I would be the first point of contact. The A frame for the wing...

    What is an affordable ultralight?

    Not necessarily. I've had close to a dozen forced landings on various hay fields, plowed ground, pastures, etc. and haven't bent anything yet. This is in Quick's, CGS Hawk, Starflight two place, Airbike, and maybe another one or two. Always important to think that the engine will quit in...

    What is an affordable ultralight?

    I have had several ultralight planes that cruise at 60 mph. My longest cross country flight to date was 700 miles.

    What is an affordable ultralight?

    OK, now I understand. The "debate" is over two place wheeled carts used for "training". Single seat powered paragliders with wheels are absolutely legal under Part 103.
