I live 5 mins from this guy, he’s quite the engineer and his passion genuine towards building these aircraft’s , unreal video jp!

[@jpkrucker]

thank you : )

[@crawford323]

Soak up every moment with him like a sponge.

[@leemnav]

Some nice controlled flying there !! Well done !! Amazed by the , seemingly easy , azimuth stick controle. You're an inspiration to many people Mr. Krucker.

[@jpkrucker]

thank you. I should have a video of it flying on floats this summer.

[@Ben-Dixey]

Thanks very much for the video, amazing and you make it look so easy, even with the backwards controls. Would you be willing to do a walk around and explanation video sometime? Details like drive train, rotor blade size and airfoil, empty weight, engine cooling ect would be very interesting. Cheers

[@jpkrucker]

yes I will do that

[@bensclassicbodywork]

Thank you. 👍👍😊

Wow JP! Once again amazingly good work!

Well, jp, you just started my day with a big grin on my face. I think I could see your grin under your helmet, too. Soooo envious!

Very happy with this one

Very cool! You are amazing...

Sweet I'll take one with pontoons and casters

[@shandusa]

Nice 🎉

[@BalajiSankar]

Great job sir. Are you using swash plate or are you working the rotor head?

[@shandusa]

What are the rpm of the main rotors?

[@bogan4009]

I want one!

[@mikemaxwell2591]

Nice job! A bit drafty but worth it no doubt. Love to put one together like it. Why the caster wheels?

[@Patriottoo2]

Perhaps to reduce chances of a dynamic rollover.

[@jpkrucker]

Castered wheels are because I'm still training myself to fly that thing.Keeps it from tipping over when I'm low.

[@mikemaxwell2591]

@@jpkrucker Okay I get it now.

[@cloudusterable]

Great machine, is this of the fully tilting head system, with no collective or cyclic pitch ?

[@jpkrucker]

yes it is and no collective or cyclic pitch

[@cloudusterable]

@@jpkrucker one other thing JP the coax reversing mechanism have you used gears, or chains ?

[@rotor-and-soft]

I see that you have a great rotor blades. Which country are you from?

[@jpkrucker]

Poland Gyro-tech

[@rotor-and-soft]

@@jpkrucker Blades are from Poland, but where are you from, where did you build it? Also in Poland?

[@leemnav]

How come you can make a complete "U" turn without moving the foot bar that seemingly seem to controle the yaw vane (s) ? Is the lower rotor set at a higher pitch ?

[@jpkrucker]

it might be I'm still in the very early testing stage.

[@crawford323]

I hope you write a book!

[@thrustprop67]

JP what is the name of the supplier you get the gears from ,,,, please

[@bradsamers3014]

Hi JP - you haven't posted for a while so I hope you are ok! _ Your current build is fantastic, I love the work you've done through the other prototypes. What rpm is the hayabusa running at to control it in the air? Please more videos!!

[@jpkrucker]

engine rpm is around 8000 rotors 700.I haven't had time to do anything with it but 'm planning to put it on floats this summer.

[@bradsamers3014]

@@jpkrucker that's a lot of rpm considering the power of that motor. What pitch are the rotors set at?

[@jpkrucker]

@@bradsamers3014 about 6 degrees

[@jpkrucker]

it's also heavy. empty weight is 470 lbs but I lifts me 200 lbs and an extra 350 lbs of sand bags.Still have power to spare.This is why I know it'll fly floats.

[@bradsamers3014]

@@jpkrucker these blades are optimised at 14-17 degrees. You could get more lift at lower rpm. There's a report done by institute of aviation in Warsaw which used 2.5m long blades. I'll send it to you

[@jmdesertadventures803]

Do you have full cyclic and collective on both rotors or just the lower?

[@jpkrucker]

none there fixed pitch rotors I use engine rpm for thrust

[@jmdesertadventures803]

@@jpkrucker so what you are telling me is that if that engine fails, you're ready together your maker. Because with fixed pitch and no engine power that aircraft will fly as well as a 20 case coke machine, instead of a having a glide ratio of slightly better than a brick?

[@airpicturesfotoflyget3953]

How on earth is the collective working? 👀

[@jpkrucker]

no collective engine rpm lifts it fixed pitch rotors

[@davidhillberg7623]

anything higher than 5 foot you risk your life, weight shift, no collective, harmonic vibrations..

[@Golfwhiskey]

Where is your collective?

[@markeezbaroon2033]

you definitely don't need an oxygen mask for this machine.

that flight was about 4' to 20' high I'm still learning how to fly that thing.
