    Re: Tell us what you are building!

    Hello there,
    You might know of, or have heard of the Steyr Puch motor. Its a flat( boxer) 2x cylinder engine. There are a few on You Tube. They were fitted to Fiat 500`s. I think they would do well in an aircraft. Also air cooled. Maybe just another option to think about. Would like to know if anyone has ever used one for an aircraft.

    Re: Tell us what you are building!

    I am at the cover stage of building a full scale, ultralight legal replica of the 1929 Aeronca C-2 Pellican. Below is a photo of it at my friend's place in Nunelly, Tennessee.
    A bunch of us got together on a Yahoo discussion that I started just for all of us to "flesh out" our ideas, and this is what resulted. It's planform is very true to the original, the fuselage is 4130 tubing, the wings are from a Challanger two ultralight, and are of 6061 aluminum "ladder" construction. It is powered by either a 42 HP, 125 pound, 84 cubic inch, flat four cylinder, four stroke, Continental Designed Army surplus Genset engine that has a 1,500 hour TBO.
    If you want an accutate engine layout, Continental also designed a 30 HP, 79 pound, 42 cubic inch, flat two cylinder, four stroke engine with a 1,500 hour TBO. Except for the crank, cam, magneto, and case, it uses exactly the same parts as the 84 cubic inch engine, only half of them.

    Re: Tell us what you are building!

    Wellcome JetFox......to my understanding this Jetfox was launched few months ago right? Here is a good place to learn alot and lots of folks out there to shear ideas and experience with you, myabe you can elaborate more on the type of materials you needed.

    Re: Tell us what you are building!

    Please I welcome any comments I am as green as they get . Learning to fly an UL without any local instruction Is a real scary thing .My instruction comes by phone and e-mail from far away.
    It the plane had control issues and they came from the sponsons and the V-tail. Both are being changed here the new floats but unfinished not even sanded a solid foam core with a better shape and more control friendly on step.
    the new tail is currently under construction and feature an innovative rib construction. I am told foam ribs with aluminum cap strips have been discussed here. These foam ribs are a bit different in that they are channel capped. I am interested in discussing the ribs with anyone. this is the components of the new tail close up is the stabilator having a 3 ft chord and is a lift generating airfoil . This style of rib construction is proving to be very light and super strong for the weight ratio at 4 oz. these are enough structure to need only the marriage to the spar tube and the le an te cap skins standard TE form I create mine from 6061 .020 @ 2.5" chord lgth. similar to those sold by Aircraft Spruce. Expecting the new tail all to weigh less than the V-tail at 10#

    Re: Tell us what you are building!

    Good morning: I am a polymath who holds patents(then given to relevant organizations)on bio medical/mechanical devices. I have always wanted to try my hand at aircraft design, so with my large blackboard, piles of cardboard, foam core, I am up to my fourth model. Each gets larger and points out needs and not needed. My work ethic has been that if, a big, if I can model it up to around 3/4 scale, then, I can build it. It would definitely fall into the experimental class as I have not seen anything like it and there may be a good reason for that. Once I finish the fourth prototype, I will put it on site for member critiques. I very much like the attitude of this site and it is vastly interesting to see and hear of what others are doing. Regards, DOWTONg

    Re: Tell us what you are building!

    Hi,
    I am STILL sanding down the plug for the little Razorback. It is slowly becoming more true. I have found that it is better to put micro on in small amounts, than trying to true up a whole section. On initial application, the micro is nice and wet. Within a few minutes, however, it begins to thicken up, and the more I try to smooth it out with a bent plastic ruler, the worse it gets...

    Re: Tell us what you are building!

    Hi all,
    I'm new member here undergraduate engineering student.

    first I have an 220CC engine and asked to design an UAV which suitable for this engine
    Until now I decided about the design to be similar to Piper J-3
    But since I'm not expert in airplanes I don't know about the length of it or even the wings
    If you can give me the estimation of this please.
    I also have a hand sketch of my design I can send it if needed.

    Here is the attachment of the engine details.

    Thanks in-advance.
