    Re: How many of you guys fly RC Planes too?

    Hi!
    Just want to share my newest RC model with you!

    An interesting thing in its design is that I wanted to build a s large as possible model with powerplant I have in stock. To achieve that, I need to build extremly lightweight structure. I manage to achieve 50% of normal flying weight for models of that size.
    My model is 260 cm wingspan, 182 cm in length and weight ready to fly 3 kg. "Normal models" of that size weights somwhere between 5 and 7 kg.

    I even made some aerodynamic calculations to check if my model will fly slow as I expected due its low wing loading.
    And amazing results from on board GPS logger, processed with seeyou software revield that expectations, calculations and ral flight data was done pretty acurate.
    I am more than happy with that!
    This could be a confirmation that there is a real chance to calculate even real homebuild aeroplane.

    I purchased so called "FPV, First person Viev" system so I will be able to piloting this plane virtually from its cockpit.
    Equippment is on the way from Hong Kong, and I am looking forward to install it and test.

    Okey, let see that model:





    and some movies:

    Maiden flight

    Model allow to take very nice aerial video shots:


    Regards!

    Congratulations ! Looks neat too. If I am correct your kite is pretty much at the peak since if scaled up into flyable real size that would be about 80 kg am I right ?

    I bought my first rc when I was 10 and I still build them and fly them now I am 54 retired and this winters build is a 1\3 scale P26 peashooter. You know there been some pretty good full size planes that started out as a rc models. Just a thought Chuck

    I flew control lines when I was 14 but remember, what goes up, must come down. I've been flying gas since I was 18.

    The first turn after takeoff looks like it was done within about 2-3 wingspans with about a 30 degree bank. How would you scale that?

    Nice going Mitja. The FPV system sounds interesting, and would add another dimension to the RC experience. Let us know how you like it...

    Right it should be this big to turn that tight turns; Fieseler Fi 156 Storch (stork) - YouTube

    Beside dreaming of and designing ultralight sailplane, in my workshop is another RC model, 1:3,5 scale vintage school sailplane CIRUS HS-64.
    Wing span 5m, fuselage length 2,5m.
    This is a fuselage preparing for "lost" foam composite technique:

    I am sure that designing and building radio controll modells is very helpful as it gives oportunity to check own ideas, give oportunity to try new materials and technologies and you can refine your skills in workshop, as each of these can help a lot when it came to real planes.

    Regards to all!

    P.S.: another video, made by my Marabu "Giant Parkflyer":

    Re: How many of you guys fly RC Planes too?

    Thats how I started flying UL's, They where at the flying site where we flew RC's. Today I love all the Micro Birds. I change motors and props and make outdoor fliers out of the indoor stuff. I have even made some float planes all Micro. They are great in the off flying season. In the summer or nice weather I fly my Experimental and leave the RC's alone.

    Nice video Mitja. Is that where you live? Looks like a very nice area. Is it a small village, or the outskirt of a larger town?

    It is just a small village, way far from the towns.

    What is the span on that ?
    --

    OOPS...5 m above.

    You have a pretty good sized printer too..are you an engineer by profession ?

    Re: How many of you guys fly RC Planes too?

    I do the r/c thing too. But mostly tiny stuff. I have a few of the ultra-micro airplanes from Eflite. The T-28, P-51, and Sukhoi. (Actually two t-28's... one of them has crashed a lot...) I also have a MCX, MCX2, and MSR. That's to say, yes, I drink the Eflite kool-aid and i like it.

    I have built several revisions of a micro DLG. I've built a Great Plains Spirit 2m. (From stick, not ARF...) A pair of Future Flight Thermal Things, and an Ace Puddlemaster.

    I really like the ultra-micro and parkflyer stuff. It means I don't need to schedule a day to go find a park to fly. I just need to wait for decent wind, and I can fly up and down my street, or around the retention pond nearby.
