Rubber-Powered Haines Racer - Anatomy of a Trim Session

Ғылым және технология

Trim session for the 24" Haines Racer at Wawayanda on 7.10.14.
Perfect day for flying, which became thermalitsic as the flights progressed from 400 - 1820 turns.

    I use to do free flight and rubber powered but with rubber power there was always this massive surge or thrust at the beginning with some disastrous results. But I learnt something today. I might go back to it after seeing this today. Rubber powered can be scratch built too so its not so hard on the pocket like RC.

    RE the Haines looking like a Caudron C.460, the R-1 Chambermaid 22" 1938 by Russell Chambers also looks like the Haines (kinda). I was positive I had the plans for the Caudron so I went looking in my plans and nope, but I did have the Chambermaid plans. Around 2001 for some reason I ran across an estate sale of old stick & tissue plans and I don't think the guy knew what he had and I thought oh my gosh, I can't turn my back on this. Anyway, I bought all but maybe three and once I got them and saw how nice they were, I went back for the remainders, but they were gone. These plans are like works of art to me and as far as I'm concerned, they're irreplaceable - they're history - they're museum pieces. It's a lot of work unrolling these, so I thought, I ought to make up a list of what's here while I'm looking for the Caudron. I'll paste in the list. Wonder if any of these are near and dear to you - if any tug at your heart? Here's the list: Megow Waco Cabin Model 23" 1935 biplane by Fred W.

    Does an airplane with a fuselage longer than a wing have poor longitudinal stability? Does it feel that the fuselage is smaller than the wing and fly more stably?

    Nice flights! When you say 2 loops of 42", is that 42" total length looped twice creating 4 parallel strands of rubber at 10.5" long?

    Thx. No, each loop (and strand) is 42" long.

  • @TexMechsRobot

    Ok. So then you have a total of 84" of rubber in two separate 42" pieces and each piece is put into a loop so you wind up with 4 lengths of rubber 21" running from the nose to the tail? I'm needing details because I'm trying to get my plane flying and everyone seems to use the terminology of "4 loops of ...." or "6 loops of..." and I can't seem to get an actual setup of how the rubber motor looks and is built.

  • @maxfliart

    @maxfliart

    7 жыл бұрын

    Here's how I translate (for example) 2 loops of 3/16" x 42" long. Each single strand would be 42" long. So in effect I am starting with a single piece of 3/16" rubber that is over 168" long (a few extra inches to tie the knot). Tying the ends makes an 84" loop, which is doubled over, making two loops, 42" long. However, before I double it over, I wind in anywhere from 140 to 200 forward winds, which allows the rubber to braid itself, and keeps a rested tension in the rubber to prevent shifts in CG.

    Is the constant turn generated by rudder offset or lateral balance weights? Amazing to watch.

  • @maxfliart

    @maxfliart

    5 жыл бұрын

    Yes....haha. Actually, it's a blend of a few things. I'd say that the thrust is what affects the constant turn the most, but then you're dealing with thrust and torque, so as the torque fades, the thrust isn't nearly as powerful. That's when tweaks to the rudder, or gurney flaps on either TE, or small amounts of wing tip weight will keep things in check as the model transitions from the power run to the glide. Each model is different, so it's like reinventing flight each time out. Even with building the same model twice, you'll probably end up with two different trim patterns...which in the end is good, because it increases ur knowledge base and experience with trimming. Glad u enjoy the films.

    The stab on this airplane pivots on the center spar to "dethermalize" it from the uplift thermal it was in that made it go so high. If this had'nt happened, Tom would probably lost it on a flyaway! Just join the Flying Aces Club of the world because all it's members are eager to share all the secrets that make these ships fly.

    Not always, but usually the wings are glued onto the fuselages except on the bigger planes, above 30" w/span.

    Here are two methods for the DT setup. Both use the same internal approach. How you decide to pop the tail depends on the model design, and what's most efficient. hallmanstudio.com/waco_DT_5.jpg hallmanstudio.com/Gadfly_DT.jpg

    I've always suspected that silly putty was used as the "viscous material" that creates the resistance. The button timers are definitely reactive to changing temperatures, so you need to be aware of those tendencies each time at the field.
