    Concepts only: Doodles without numbers

    I've thought about the moment created by the drag of the floats, maybe mounting the engine in tractor configuration would help partially cancel the moment? Also, by elevating the wings from the water's surface, the wings will be (at least partially) lifted from ground effect, potentially making...

    Concepts only: Doodles without numbers

    My idea for an all-metal aluminum ultralight float plane. This design has floats as opposed to an integrated floatplane hull so the floats can be bought or replaced, and to give the prop better clearance from the waterline while keeping thrust inline with CG. The wing would be monocoque and...

    Flyout game

    Thought I'd share a fun game for anyone that's interested. It's less a game and more aircraft modeling software that lets you fly your models. It's pretty primitive, but I found it very fun. The editor is like OpenVSP but easier to use, less complex and you get to fly your plane at the end...

    Flying wing as cheap and simple option for basic fun flying.

    I don't think that a low aspect ratio planform is best for the original mission set out in this thread. If the goal is to make something dirt cheap, simple to fly and simple to build for beginners I think a plank or swept plank is superior. The build process is far more straight forward and...

    my part 103 ultralight build -thread

    Hey everybody, I'm finally back from my vacation. Now its time to start building my plane. So, yesterday I went to Lowes with my dad and we bought enough wood for the first part of the plane. They did not have T-88 epoxy at Lowes, so my dad told me that I could just use the wood glue at home or...

    my part 103 ultralight build -thread

    Alright, I gave myself a deadline of June 30th to have my design completed right? Well on the 24th I'm going on a trip with family and won't return until early July. What this means it that these few days before June 24th are my last chance to make design changes before I begin building it...

    my part 103 ultralight build -thread

    Ok, so I revised my design (pictured below) and I'm a little happier with it now. I've decided to go with a tapered 4-sided T tail. CK LuPii, I love your design, but my tail will be a T-tail, and I don't think that your design would provide enough support for the horizontal elevator in my case...

    my part 103 ultralight build -thread

    Alright, I need some help here. Bellow is a side profile of the entire tail section. There is 7 ft between the trailing edge of the tail and the trailing edge of the wing. I have two questions, one, how many sides should the tail have, and two, what should I do to make the tail surfaces more...

    my part 103 ultralight build -thread

    Yeah, I'm starting to think that maybe using a wheelbarrow will create more problems than it will solve. My UL will be almost entirely wood, the only exception being a rectangle with an X in it made out of aluminum that connects the fuselage and the two wing halves. I circled it in the picture...

    my part 103 ultralight build -thread

    Thank you, I am very lucky to be able to be apart of a community of such knowledgeable and helpful people. I'm going to use the entire wheelbarrow minus the little supporting legs in the back, and with the handles chopped off. The wheel in the front will be used as an overkill front wheel in a...

    my part 103 ultralight build -thread

    I feel like I'm asking all the wrong questions for all the wrong reasons here. Sorry for wasting your time with the wheelbarrow question I believe that it was a stupid question to ask. And yeah as BJC pointed out on my profile I'm 13, have little to no engineering experience and am trying to...

    my part 103 ultralight build -thread

    Well thats exactly what I'm looking for but its also worth half of all my savings. I think that I'm going to try to make do with a regular wheelbarrow. Thank you for finding it though.

    my part 103 ultralight build -thread

    Yeah, I think so too. I'm probably just going to end up buying a regular wheelbarrow since those boxy ones don't seem to be commercially available. It's not like I can't make a traditional wheelbarrow work for my purposes I just believe that one with edges would be more convenient.

    my part 103 ultralight build -thread

    I used the values you listed in your post and I got a volume of ~17"x17"x1" for the horizontal volume, and a volume of ~11"x11"x1" for the vertical volume. Thank you very much, your advice was really helpful. I'm going to round out everything and go with a volume of 24"x24"x1" for the vertical...

    my part 103 ultralight build -thread

    Alright this is a weird question, but anyone know where I could buy a wheelbarrow like the one bellow? All the wheelbarrows that I've seen have rounded edges which get in the way. I believe that most wheelbarrows do not have edges like the one bellow because it makes them harder to cast, and...

    my part 103 ultralight build -thread

    Hey everybody, my name is Daedin and I plan to build a part 103 ultralight. I've been designing the ultralight for the past 11 months, and while that sounds like a long time note that I had school going on at the same time for 9 out of those 11 months, and school takes first priority. But I just...

    Anyone have any recommendations for a 15 hp engine under $1000?

    I'll consider it, but (however idiotic it may be) I am quite married to the idea of creating and designing my own plane.
