    Ultralight Float Plane Concept

    Having adapted floats to a few ultralights over the last 20 years and been kite foiling for the last 3 years I would say it would be very difficult to pitch control a plane purely on a foils.

    Is there a cheapest/lightest/simplest wing structure other than aluminium tube and fabric?

    Yes the scout was my first aircraft and dead simple. We had it on floats and was the best bang for bucks ever. It would be a perfect battery electric project.

    Converting Sail Cloth a/c to standard fabric covering?

    Stick with the original Dacron covering.Your costing analysis has a lot of holes in it. Just the painting will be a PIA and a lot of work and wont look as good.As others have mentioned, resale will be a issue.

    Could floats be this simple in an UL ?

    It just a basic rag and tube meets 95.10 Recreational Aviation Australia MTOW 300 KG. Iam only 65 kg so that helps. Floats are hollow fibreglass weigh about 32 kg all up. They have a Vee bottom not flat which provides better handling and directional stability.

    Could floats be this simple in an UL ?

    Well have been flying on wheels for about 10 years then the floats came up for sale and I decided to adapt them. Just re calculated the so the cog remained exactly the same and it flew perfectly as with wheels.

    Could floats be this simple in an UL ?

    So her's my Rotax 503 powered U/L. Can change from wheels to floats in about 15 mins,almost the same both modes but a whole lot more fun over water.

    "Jet ski of the air"

    This one is 503 rotax powered, cruises at 50 knots and can be configured on floats or wheels. Normally lives in a trailer.

    Belite 2 Place

    IF it had a ground stike the A pillars will fail in tension and I would doubt if they would offer much resistance in Compression.

    Rotax 582 grey head

    Run it for say 2hrs then do leak down and compression tests. A lot of 582's have done 1000 hrs easily. My 582 cruises at 5500, and the 912 5000 rpm, not much differance.

    Hi, Have a existing plane with dacron wings front and rear spar 50mm and 45 mm tube, chord about 1500 mm. Any suggestions on how to reasonably accurately measure the washout with the dacron in situ?

    Float Design

    Shawn, The plane is a Lea kestrel 95.10 design tail dragger,came from Ces Lea in Brisbane. I can fly on wheel or floats, it lives in a trailer and is easy to rig. I purchased the floats from Perth WA. They were built for a T85 thruster which is about the same weight as the Kestrel. The only...

    Float Design

    I recently put my ultralight on floats and the illustrations are a good starter. It flew perfectly first time up but I did make sure that the COG was not altered from when configured with wheels. It important that the ONE float at least displaces enough water for the MTOW. The step position...

    Trailer Hangar

    Wing covers are made from sign board (alum/polyethylene/alum sandwich) the rest is just rhs and panel rib sheeting.

    Trailer Hangar

    The wing covers are separate and bolt on. Can transport plane fuse complete and wings suspended inside easily. The intention was that its a relocatable hangar, and not for a rig/de-rig type of a/c. Its very quick to get out/in and no a/c to move as in some hangars. Needs good storm tie downs...

    Kestrel ultralight on floats

    Question on Drag on the above set up. If I lighten the two cross bars that connect the two floats (50x3 shs) with a series of holes, would the drag increase or decrease? I will make sure the section modulus is not compromised as there is some BM in the rear bar. I was thinking of a series of...
