Well, you almost impressed me. Just make a PTO from your main power plant to do this spin-up thing considering the weight penalty. You could add 'electric start'... and now that you have a battery and a starter, make the starter a starter/generator to power the electric spin-up motor. All of this justifies the rest. How about this?: Come off of the main power plant with a differential. One output goes to the prop and one goes to the 'spin-up' stuff. 'Lock' the prop for spin-up, and once 'spun-up', lock the spin-up so the prop is direct. Use an overrun clutch somewhere in there. Oh-my god ... you almost have a 'real' helicopter with that. I know the swash plate stuff adds way-more complexity/cost, etc. That nonsense being said ... Kudos for the effort, and thanks for the post!
Fantastic. Thanks for your reply earlier. Two more questions for you. 1. How many complete, dead top rotations can you get in a single charge. 2. How do you know how much power to give the prerotator during spin-up. Thanks again. Mike
The pre rotator battery isn't charged in flight. It has an external lipo battery charger although the charger runs off of 12 volts and I have used the ship battery as an input to the charger and charged the pre rotator battery, so I guess you could figure out something, but its probably more trouble than its worth. 1. Two complete run ups used 1/3 of a 5000mah battery, so I guess you could assume that you could get 6 runs out of one charge. It took about 15 minutes to charge the battery from 2/3 to full capacity. 2. I just start out slowly taking 40 to 60 seconds to get up to speed. I may even be conservative because I just started testing it.
I still haven't had flight instruction yet, but I did take it to air Gyro in Spanish Fork, Utah and had it flown by the CFI there. He stated that it flew fine and no adjustments were needed. I hate to have it sitting in my garage, but sometimes life gets in the way and slows down your progress.
The gyrocopter as originally presented could pitch nose over, go inverted and ultimately lead to a fatal crash. This phenomenon is referred to as porposing or PIO - Pilot Induced Oscillations, which I as a pilot, sailplane, powered, and gyrocopter, resent and when discussing this will tend to refer to it as Pitch Induced Oscillations, because there are a few other factors that can lead to a sudden rise or drop of your aircraft's nose which will lead to over correcting for the problem and then starting a series of other (over) corrections due to 'panic' which usually leads to the eventual pitch over and crash. There is a basic remedy to prevent this from happening by lowering the Center of Thrust , but due to the amount of time it takes to properly explain this, the best thing for you to do is to go onto the PRA site and refer to their explanation.
original designs had the keel pretty much inline - front to rear. this forced the engine to be placed higher in the frame, so the prop would have enough frame clearance. The thrust line was higher than the center of gravity- Certain conditions could 'push over' this design then it's tumbling out of the sky. This is a non recoverable situation. So, stagger the keel line, puts the pilot higher... lower the engine a little, and the thrust line is now at, or slightly below the center of gravity.
Point well taken, cause obviously he doesn't (fly higher, well you know). Would have been more informative with a brief description of what was being performed with the per-rotator and the taxi test to verify the handling qualities in maybe a minute tops.
if I wanted to see gocarts I would have looked that up . impress us man and make that bird fly . hell I could just take off and run bare foot across the sand a piece and back and make it more exciting than that.. shit dawg I want my money back
For those who understand gyrocopters, this is great. Mechanical system works, but is just that...Mechanical.
это был незабываемый полет.не отрываясь от земли)))5 минут впустую
This thing went back in time causing him to finish the flight before he started so he just taxied back to the hangar.
Ooooo boy 5.34 minutes of watching some guy tool around, it's like watching kids riding go karts
I forgot to ask earlier, can you charge the battery pack in flight?

Too heavy and complex IMO. Better to use a hydraulic system or an electric one than a transmission.

Did anyone see that Butterfly actually flying?
What was the location out of curiosity?
Hey Mate, can you provide a link to the LIPO you're using? Thanx Gb bg
sounds like a sci fi movie sound effect ,,, epic
I cant handle all the excitement. A true daredevil. Uh i think the rotor needs to be spinning for it to actually fly.
Can you make the propeller also be powered by an electric motor?
But does it fly ??
What do ya do to charge the battery....fly it?...lol
I would think a supercapacitor pack would be lighter weight and could fully charge faster and dump the needed energy for take off.
No take off after all that?
I know, you're right. Don't worry I finally got there. It's on another video.
Right? Another 20 rpm or so an it would have at least got off the wheels.
It was a year, did you get it flying?

Is it a goofy go cart or does it actually fly ? Numb nuts !
WHY DID I NEED TO SEE THIS?
el video se me ha hecho muy o maravilloso
SI SENOR.
Can someone tell me why some designs sit so high?

Don't fly higher than your willing to fall?

what he must have chickened out its a gyro copter not a sand buggy
I think he made this walker for their childrens 😂😂😂
Use full topic

shit dawg I want my money back
its very skinny on the undercarriage ,,, where did those six years go ,,, lol
Что то он очень низко летает )))))
Wht the fkkk he dont lift
may I nominate this for "The Most boring, time-wasting Video" award
completement con........
Rubish vid
This is the safest none flight I've ever seen. Boooring.
