    Lets see your original designs

    If you have built and flown (any length of flight qualifies) your original design, lets see it. It can be any type of model plane including scale if you drew the plans.

    It would be interesting to see how much and what variety of craft are created.

    Provide the basic details of the plane as well of course pics and other notes that might be of interest about the build such as when, why, length of build and current status.

    It doesn't have to be current... any creation in your modeling history is more than welcome.

    RE: Lets see your original designs

    My only design is a 96" sport/aerobatic RC powered by a 35cc gas engine. Weight is 16.5 lbs constructed with a foam cored wing and balsa stick airframe with forward lite ply box construction covered with UltraCote.

    The design goals were for a '30s era sport/racer look having good flight qualities for traditional and somewhat scale aerobatics.

    The design was conceived during the spring of 2011, plans drawn during the summer and finalized in late December. Construction began in January of 2012 taking four months. It currently gets flown several times a month.

    RE: Lets see your original designs

    This model was first flown in May of this year. Has, so far, accumulated 6.1 flying hours.

    Span is about 80". No plans ... I just made it up as I went along.

    Undercarriage is bungee sprung, rather like the early Fokker monoplane fighter. Works very well.

    The wing is secured by a single steel pin at the TE, which makes assembly very easy. There is, of course, a tongue at the LE of the centre-section.

    Power is my modified YS 1.20, which is a delight to use. Since the fuel tank is under the wing, there is a fuel pump.

    The fuselage is braced internally with rattan strips ... just an experiment. Successful, though.

    Twin flight packs are carried.

    Quite a few bracing wires around the tail end; mostly there to add character.

    Rudder, skid and elevators are operated by exposed closed loop.

    Cockpit and area immediately forward of pilot are made from Cornflakes packet.

    Wheels are homemade. Ply, ali sheet and O-ring material. They weigh the same as Flair vintage wheels. A slight cost-saving, but, "Hey, they're my babies."

    General covering courtesy of Solartex, painted with acrylics.

    Marking is Italian ... just made it up... simple, but tasteful, I think.

    Powerful flaps demand respect.

    Very pleasant to fly. No bad habits. (just like me!)

    In essence, it's a pattern-ship and it goes pretty much where you point it.



    My design philosophy was to create something with a bit of character, but which was sporty. It's a good aerobat (well it's better'n me) but will stooge around at low speed at very modest power settings. Ground handling is very good, despite the tail-skid.


    I like it.

    RE: Lets see your original designs

    As a matter of fact I just finished one! A 30cc 1/4-scale Pitts S-12 designed for 3D, I call her the "Pitts Dash".

    Designed the entire aircraft in 3D CAD, then had the intricate parts laser-cut and filled in the rest. Spent long hours with a calculator and books on aerodynamics and it paid off, she flies solid.

    Here is the build thread:http://www.rcuniverse.com/forum/m_11..._1/key_/tm.htm

    RE: Lets see your original designs

    Here are my four canards I designed just to be different. Sorry for including me in the images but they are the only ones I have. They are in chronological order as you can tell by my hair line. All had the CGs are well in front of the wing and about two inches in front of the main wheel axels. I got the location of the CG from various equations I picked up from the magazines and books. They all survived the first flight and I made the final CG adjustments after that. The first three were powered by VECO 61s. I do not have the details for them any more. The last one is powered by a Brison 2.4. The wing area is 1120 square inches and it weighs 23 pounds which includes 42 ounces of lead in the tail. With a wing loading of 47 ounces per square foot landings were always fast. Getting the proper location of the Cg for canards is easy now with the use of this website. I did check it against what I know and it is accurate. The first three plans were hand drawn and the last one was drawn with AutoCAD. Dan.

    RE: Lets see your original designs

    Ok.
    I am a returnee. About 1983 to 1986 I was messing around changing Craft Air's Drifter II.
    I quit all R/C in 1992 and the "evolution" had stopped at 100 inch span poly and spoilers.
    Drifter IIs were adaptable or so I and an OFB thought.
    V-Tails T-Tails, 2M and Std 100". Flying Stabs, Polyhedral wings, straight wings with and without ailerons and on and on.
    We found it a great trainer and good to experiment with.
    I now wish I had never quit.

    I returned in 2008 and scratch built this plane in 2010 as a mule based on the evolved 1986 version to serve as a trainer for myself as well as others.
    Therefore I built it a little sturdier but kept simple and stable.
    Rudder Elevator and Spoilers, in this photo the blade and frames for the spoilers were installed but I didn't have the right servos at that time.

    I widened the fuselage one standard servo width wider in case I want to use a channel for something else. Chute drop? Candy drop?
    It is all balsa and spruce and a dash of ply. I fly hi-start mostly so I didn't use carbon fiber in the spar as I would if I built it now.
    I never named the thing in 1983 so why start now? Airplane num 1 I guess.
    I am overall pleased with it, it flies like a floater like a big Drifter II pretty much. Not as twitchy as a 2M though.
    I bet some folks will recognize the lines of TomWilliams' 2M aircraft.
    Yes, there is a new Airplane num 2 based on the 1986 plane more LSFtask oriented and less "trainer". It is stuck in the CAD-land right now though.
    Good things to all

    RE: Lets see your original designs

    This is my Gemini GT40. It is the .40 size version of the Gemini GT25 which I designed a few years ago. It has a 66" wingspan, all wood construction, SpringAir retracts and is powered by two ThunderTiger Pro .40's. A very good handling twin with a top speed in the 130 mph range. Also has good slow speed handling and is very maneuverable, a pleasure to fly. Flaps allow smooth landings with no tendency for the plane to balloon when the flaps are lowered.

    Night bipe. 32" suffered its demise when I got disorientated on landing approach. should have become more accustomed to it before I flew it at night.

    RE: Lets see your original designs

    I designed and built this one, called it the "Purple People Eater".
    K&B Sportster 65 for power. Only needed about 1/2 throttle. The most enjoyable part of flying it was shooting touch and goes. Darn thing flew like it was on rail road tracks. I could get 30 minuts on a 16 ounce tank.
    Construction was foam board, Paper left on. Fuse sides, top and bottom, foam board. I did use some ply as doublers up front to cary the fire wall and all other stressed attach oints. Tail feathers more foam board with spruce spars. The wing ribs were also foam board. Spruce spars, balsa leading edge and trailing edge.
    Covering was fabrick and dope.
    I think it was about a 6' wingspan.

    And here is another plane I designed and built. This one control line. Grossly overpowered with a piped .60. It about pulled my arm off.
    Again fabrick and dope finnish. Normal balsa construction this time

    RE: Lets see your original designs

    This is a stand off scale version of a U-2 that I scratch built. I made my own mold and the fiberglass fuselage. The wing is built up balsa and covered in Ultrakote. The fuselage is 35" long and the wingspan is 67". It weights 3 pounds ready to fly with a 4 cell li-po battery. I got tired of only getting four minutes from my EDF RC Lander F9F Panther. This plane now has about 30 flights on it and it flies for 8 minuets.

    RE: Lets see your original designs

    I've done a few sport types in the distant past but did not take many pictures and what few I did take are 35mm. No scanner so can't share them I'm afraid. These days all my designs are scale, typically WW2 subjects but not exclusively. Here are a couple recently completed and a couple still under construction.

    RE: Lets see your original designs

    I engineered, disigned, this plane. It's for fun flying. 58" wingspan, 59" long, powered by a O.S. .61 FS, J R 7202 radio. It even flies the pattern pretty well. Unfortunately, it can't be classified as SPA or CPA. One of the other members of my club flew it and his only comment was, " Sweet" !

    From looking at all these originals, and they say that there are no more builders !

    I have a long running love of the old NotForSale design, and my control-line roots are evident in a facination with profiles. Lots of fun!
