    Hello in Australia!, We are on similar paths. I used to fly an Airfer Tornado before switching to these little microlight helos. Thanks much for the comments. Testing on this sit-down model should start in the next several months. Work & other life's interuptions have slowed things down a bit, unfortunately. Still all is looking very well for a positive outcome & flight! I STRONGLY suggest you get into these little micros. They are a blast and will be fun little flyers!

    thats exactly what i had in mind, i never thought someone would think about it, i made an rc plane exactly same setup, this is a lot of hard work, good luck.

    Your project looks very interesting, and feasible; I hope everything comes out just right. Also, I like your chipboard walls!

  • @MikeUSA777
    @MikeUSA777  11 років тому

    Yes, the info you provided was very well thought out! This particular project is now in NJ being completed. A larger version coming soon :-).

  • @MikeUSA777
    @MikeUSA777  12 років тому

    Some good points....... the 20-30 feet is a safety thing. Will it go higher - absolutely. These are prototype builds. It may seem expensive to you, but in relation to the "bigger brother" to be built following this one, it is dirt cheap! As for the 30 feet - I live in an area filled with large pastures and rolling hills. If you have ever flown any UL craft at all, you might understand. To eventually cruise through field after field jumping over small hedge-rows at low altitude WILL be a blast:-)

  • @MikeUSA777
    @MikeUSA777  13 років тому

    Hello striderfly, Thanks very much :-) ................ Safety factors, mainly. The rudder system stayed the same - just using foot control vs. left hand control (also a bit safer and more of a "normal" feel).

  • @MikeUSA777
    @MikeUSA777  13 років тому

    No, the downward air thrust turns you against the rudder. In hover, you would just spin though. Doesn't take much !

  • @MikeUSA777
    @MikeUSA777  12 років тому

    These machines, in the next step from what you see here, can become very practical. Again, redundency with even two motors could provide the safety needed - using quality equipment, of course. Done correctly, an engine-out would allow safe landing with the other motor. The Simonini / MZ 313 would be my choice or the Aixro 50. As for a BRS, yes, the height would be needed for deployment. That said, these coaxials have a stationary shaft. Hooking a BRS to the top would be extremely easy.

    @MikeUSA777  13 років тому

    You are absolutely right, kz1300club. Why it has not been done or attempted yet in the US, I am not quite sure. The Aixro XR50 motor would be an excellent motor to use. Just two of these very light and powerful motors would give almost 90 HP. Cost would be steep on the motors, but as you say, combined cost would still be at a third that of the GEN.

  • @MikeUSA777
    @MikeUSA777  13 років тому

    Very possible, noname1963, but these are designed for the utmost of simplicity and control. Variable pitch control is a good addition, but slightly more complex in control / flight.

  • @MikeUSA777
    @MikeUSA777  12 років тому

    Hello 8883iron,
    A friend of mine is actually using the motor you mention in a true backpack helo project in Scotland. It is a fantastic choice in motor, especially if combined with multiple units. 4 of these would be quite powerful with minimal weight - Go for it !

  • @ExMachina70

  • @striderfly
    @striderfly 13 років тому

    Excellent work Mike. That hub is very cool looking. I wonder, what made you transition from the three legged thing you were doing before to this one with the seat inside the square? Is it the addition of the rudder? I would think having your feet involved with the landing would "feel better". . .

  • @MikeUSA777
    @MikeUSA777  13 років тому

    Hello kz1300club, Yes, I agree with you - the GEN-H4 is a very well built machine. The 4-motor config. is excellent for safety. At this point, there is still not a firm distributor in the USA, nor are there many GEN's out there. It is a mixture of a lot of things - ongoing developemental research / testing, US sales issues, backlog of buyers wanting them, etc. All said, you CAN get one in the US, but your cost will be in the range of $60,000 And have a 2 year wait once all is said & done......

  • @MikeUSA777
    @MikeUSA777  13 років тому

    Yes, the PPG motors would also be a great choice for micro-helos. I used to fly Top-80's and then the Airfer Tornado with an Eden II years back - great machines and fantastic power out of the Airfer.On the build here in the US?, probably just about anyone with a good shop and the right tools- and the cash, of course. Even building for profit as long as they are sold in "kit" form with the right marketing.

    Twin-tipped fat snow skis are extreamly durable and light. They would make great skids for Your copter.

  • @MikeUSA777
    @MikeUSA777  11 років тому

    probably a tough-to-do project, turbo charging, but not impossible. I know someone working on that project right now. These modern (Vortex Super ROK) motors are highly advanced now - they should handle it, I would think.

  • @kz1300club
    @kz1300club 13 років тому

    @MikeUSA777 Well, I was thinking about the 40hp Paramotors instead of the Aixro's, but the main thing is they're extremely light for the hp output. Expensive but light, and that's imperative if you're going to improve the flight characteristics. Apparently they underpowered it because they already had the little 10hp 2cycles. So who could build this do you think if the money was available? It's patented, but anybody can build one for themselves if it's not marketed to the public.

  • @MikeUSA777
    @MikeUSA777  11 років тому

    You know, that is an idea well worth experimenting! The only draw back would be that the cone may direct the delivered force too far outward and not give as much downward force. Still, Some type of design like you mention, I'm sure, would increase some efficiency.

  • @MikeUSA777

    Very Cool! Think that there will be homebuilt copters designs that will be battery or graphene supercapacitor powered anytime soon? (not an r/c toy)
    Playing with the idea of a battery powered tip jet design myself. Like old Jet Jeep, or Do 32. Copters are a very fun subject. Thanks for this post.

    Great job! I want to develop a pretty similar project like yours here in Brazil, but on my own. I got all the stuff to build it, except for the two-bladed airscrew. I really need those blades. Please, where did you get’em? Who did you buy them from? Would you help me, please? I’m too excited to have my own machine working and I will have it done as soon as I can finish it. I promise you I’ll pay you a visit, from the sky!!
    Thank you Mike.

  • @MikeUSA777
    @MikeUSA777  12 років тому

    You are right there. Only problem, you'll need a runway for a gyro. A VTOL machine, there is really no limit to where you can fly or land :-)

  • @MikeUSA777

  • @MikeUSA777
    @MikeUSA777  13 років тому

    Hello @1bengrubb, Seems you know your stuff ! ..........Yes, Schoffmann's blades were fixed, as these are. This mini will not be subjected to the forces of "normal" helo flight, nor are these propellers as long and flexable as standard helo rotors. Initial testing has gone very well with my Schoffmann. Motor rpm, for my application, in flight, will be around 10,000 - 11,000 at peak used throttle (max out on the Vortex is 14,000). Rotor - about 1,000 - 1,100 I believe. Bal. Chute - coming :-)

  • @michaels5691
    @michaels5691 12 років тому

    How were you able to rotate the engine to a vertical shaft position without causing all of the oils to rush toward the piston while leaving the crank bearings dry.
    Did you make any internal changes to the motor?

  • @MikeUSA777
    @MikeUSA777  13 років тому

    I've thought about a web site, but just don't have the time, unfortunately. But, feel free to post the links to the vids I have if you want! I love your water rocket launcher design !

  • @thegreenfiddler1
    @thegreenfiddler1 12 років тому

    Hi. Great concept but why not use a clutch on the top rotor to vari the speed difference between the two rotors to turn left or right. Then you could completely eliminate the rear tail fin and boom and probably drop your weight another 20lbs. Wish I had plans to check out.

  • @noname1963

  • @MikeUSA777
    @MikeUSA777  11 років тому

    Vortech Super ROK with 35 HP. Based on this design and craft weight, rotor lift, etc, 25 HP would be a minimum. This Vortech - with its very responsive and smooth throttle, low package weight and reliability - is a perfect motor for this application.

  • @kz1300club

    Hi Frits, ......one step at a time, my friend! :-) Still, even with the gear lube on, this hub will run 20 minutes straight with no heating or wear issues at all. Its one smoooooooth machine :-)

  • @BrilliantDesignOnline
    @BrilliantDesignOnline 13 років тому

    Nice review video.
    Ballistic chute is ineffective below 100'-150' or so, so don't count on it. Even so, 20' is VERY high,so if engine fails (which it inevitably will) take the unit, suspend it 20' up and drop it with you in it at x mph-see if you like that scenario-I think you won't. Not saying don't do it, just saying..I suggest radiator aft horizonally mounted with some slant angle for rotor wash AND fwd cooling, and weight balance. Fuel tank mounted above seat inside of frame top for CG stab.

    Mike -- what' the latest? Seem to recall that you were moving in another direction due to liability issues or something? Would be interested in knowing the current status and what's left of the assembly? I'm a competitive karter and yes, the Vortex ROK is a beast, as is the Super Rok... The Parilla X30 may be a good option to -- I think it has a balance shaft and may have less vibration.... PM me if you'd prefer.... Regards, ~Ted

  • @MikeUSA777
    @MikeUSA777  13 років тому

    Hello @vondeliusc, The ballistic chute will be an add-on once a larger model, multi-engine is built in line after this one. As for the height concern, 20-30 feet will be the limit. that does not mean 3 hour flight at 30 feet, rather 10 - 15 minute flights that will more likely be 10 feet - with a max height of 20 - 30 feet on OCCASION. As for your "drop test" scenario, you need to relisten to the end of the video. Not even an idiot would fly more than 5 mph in this! The rest?... obvious.... :-)

    Actually, light-weight 4-point restraint harness - not yet installed.

  • @kz1300club
    @kz1300club 13 років тому

    @MikeUSA777 Being that it's an ultralight and it's only 186lbs approx, then I think someone in the USA needs to be looking at building something similar here. 40hp total from 4 engines seems a little underpowered. I know they were talking bumping to 60hp. I'm think 2 or 4 of the 40hp rotary engines they use on the paramotors these days. Very light and running on just 2 would be plenty of power albeit expensive. No reason we couldn't make this here for $15k minus the motors.

  • @MikeUSA777
    @MikeUSA777  11 років тому

    Yes, emergency kill switch connected to controls - in thumb's reach

  • @MikeUSA777
    @MikeUSA777  13 років тому

    Actually, that has been done on a somewhat larger scale back in the day ...........look up the Kamov Ka-56. Same could happen on one of these little micros before too long - similar to the old original ParaPlane PPC.

  • @JetPack9290

    Mikeusa777- is it possible to design and build a maned micro Helicopter that can be folded up into a big case for easy portability?

  • @ExMachina70
    @ExMachina70 11 років тому

    Do you have a cut off in case the throttle gets stuck?

  • @MikeUSA777
    @MikeUSA777  12 років тому

    It all depends on design. A true strap-on "back-pack" helo might only need 20HP IF designed right. The helo you see here has a 35HP motor - Vortex Super ROK, 125cc. 40HP would be better. The fact is, unfortunately, WEIGHT to HP ratio is EVERYTHING in these projects, not just rotor design as one may think. That said, extreme light weight to high HP motors like these will run at least $3,500 and up to $7,000. The only way around this is redundent motors, increasing design difficulty.

  • @MikeUSA777
    @MikeUSA777  13 років тому

    Thanks much, rbp864 ! Yes indeed - this is a slow flying fun field cruiser. 10 - 15 feet with some 25-30 foot short hops for additional fun. Some narrow minded people look at these little helos and think they are "death traps" ....... because in their lack of common sense thinking, they're picturing the little machines doing 185 mph combat rolls at 1000 feet like an AH64 ....LOL. EVERYTHING has its limit. Ya gotta keep it realistic.

  • @MikeUSA777
    @MikeUSA777  12 років тому

    This motor is a liquid cooled motor by design - air alone won't cool it. The Vortex Super ROK 125cc motor you see here has about the highest HP ratio -35 HP- to weight -51 pounds total run weight - than any motor in its price range - about $3,500. The only true air-cooled design motors, having the same or higher HP to weight ratio, will run about $5,600 and up. Its like anything else - Money!

  • @MikeUSA777
    @MikeUSA777  12 років тому

    Hello, No, autorotation is NOT possible on this micro machine. A machine like this should only be flown at very low heights and slow. These are basically concept vehicles and also helos to be constructed at the most minimal of weights. This one is 110 pounds complete with fuel. As for the rotary motor, YES INDEED, that would be a great way to go!! The Aixro XR50 would be my dream motor. Just too expensive for me.

    I"m dying of antisapation! If you need a test pilot I'm there. I once(or 3 times) jumped off our barn roof and survived so i think I'm a qualified test pilot. QUESTION I noticed your blades are fixed in position with 2 bolts and helicopters always allow the blade to pivot to prevent ocillation did shoffman have his blades fixed like that? What was his diameter? What RPM are you planning for your motor and rotor? OH! Add a ballistic shute like Martin aviation did and go as high as you want!

  • @MikeUSA777
    @MikeUSA777  12 років тому

    The dynamics of autorotation can be thrown out the window on one of these single engine sub-microlights. Just not going to happen. The exact configuration you see in this video - with a rudundant 2 or 3 engine set-up is where you want to go for ANY real altitude safety, still no auto-rotation, but safety in numbers. This machine should only be flown for short trips through fields, etc at no more than 25-30 foot height - SLOW speeds. Cost - figure on $8,000 - $10,000 with all new componants
