RC V-22 Osprey Testflight #3 with jet-engine (full fuselage)

[initialsareAK47]

You should try to make it horizontal flight capable, also the reason the nose is going up is because the propelers are supposed to be tilted a little while hovering around, to hover in place the should be straight, and to fly they should be sideways. Still learning about rc's, plan to construct 1. any advice on electrical components will be helpfull. i plan on making a regular beginers plane.

[Cheesyfreezey]

Dear santa...

[LETSD0THIS]

Does it go any higher?

[ProNoob05]

18 Point Streek



[biomech]

model is fairly big, you should be able to add retractable landing gears in it. And lights. =3

[gobyheli]

@biomech

retract is onboard and still works (Gietzendanner)

lights follows when flight tests are finished

regards

[EvilPyjamas]

so it hovers but can it fly?

[piotrstapor]

I think your nose-up problem is due to pendulum effect, common in all rotary wing aircraft.

[rcpilotp51]

reducing your flaps' angle of attack during foward flight will help keep the nose down. thanks...happy flying!

[stoddern]

I'm sure you or someone has figured out the extreem nose up issue by now but if not I suspect it's from the way you have the exhaust exiting and as you throttle up it is producing to much thrust in an upward direction on the tail

[AZIlluminati08]

please win awards with this. you deserve it.

[SlamDuncDrummer]

Serious friggin props man. You have managed to do something that it took the U.S. Military about 10 years to do :-)

[usmc1stin100]

@SlamDuncDrummer correction, took bell boeing 10 years

[SlamDuncDrummer]

@usmc1stin100 - touche. 

[Batchelli]

Very nice model!

[blackhawk438]

Is that legal?

[antoniskirkos]

Hi!Maybe as it starts to move forward the tail gets into the wake of the rotors and it's pushing it downwards resulting in nose up!Keep up the good work!!!

[SolarAlliance]

Would it be possible to make such a VTOL purely jet-powered, with no rotors?

[peepsbates]

u shud make it so that it can drop little army men out the back when its landed :D

[LiquidSexWax]

THAT IS KICK ASS!

[seminolePP]

Very cool turboprop, must be a real mission to keep the throttle under control!

[Mateo12368]

The goes up because all ospreys do that

[SuperCoolDude2014]

Pandora

[angelisreal]

The reason for the 'nose-up" is because of the airflow coupling when the blades are biting the air. I would suggest adding the Til Rotor feature that is used to overcome this issue.

[PERIZ99]

Nice..!!!

[Hibbicon]

Super Teil!

[tracym427]

Very nice..

[20NASCAR2020]

can u email me the blueprints?? i want to make an aluminum version....

[piratecheese13]

i hate to tell you but i think those are propelers

[violinbubi]

@piratecheese13

who said a jet turbine couldn't turn a propeller/rotor ?

what do you believe a modern helicopter is flying on - steam ? ;)

those engines on that model seem to work like the real v-22 or a normal helicopter with a turboshaft, similar to a gas turbine producing more shaft power than jet thrust.

by the way, i'm sure you know turboprops on planes?! they produce shaft power to turn the propeller and jet thrust, see for expl. the tupulew 95 bear...

[piratecheese13]

@violinbubi to tell you the truth this comment was the last one i was expecting to be replied at and infarct i think the reply feature was a bit patchy 3 months ago when i created it...

anyways i think modern helicopters run on gas and infarct i believe jets also work on the same fossil fuel just modified and processed different

ether way i defy you to convince anyone that there aren't propellers on that plane

[Freakman33333]

With this fog it looks much more realistic!

[bigt129]

if the aircraft is well balanced nose pitch up usualy means horizontal pitch is up note you also have flaps set down which contributes lift in forward motion

[ipodkiller6]

very cool. you crash it yet? haha

[KoolThing14]

You should sell these cuz I vant von :3 How much did it cost to make it?

[gobyheli]

@KoolThing14

Hi,

have no kit available.

Maybe in future

[toysbyus1]

Beautiul job, man.

Does this balance approx. 1/3 of the way back from the LE of the wing? It seems tail heavy from the video.

That would cause the nose to lift as soon as you start moving forward.

You're close.......very close.

Steve

[dodgedart74]

beautiful

[7249xxl]

yes i want to make them myself but can u explane because i dont know how

[PERIZ99]

Excellent-

[7249xxl]

own disign or you buy it beceause thats amazing i want one

[gobyheli]

@7249xxl

Hi,

It's a self made fuselage. You want to make the mechanic parts yourself?

[7249xxl]

@gobyheli yes yes yes yes tell me how i even give you my mail if i have to

[7249xxl]

@gobyheli eys yes yes i realy want to yo uwant my mail so you can send pictures ore somthing

[mrmoney185]

well i bulit mine but mine could turn into a airplane and helicopter it took months to build

[robertcoxon]

you are a very talented man indeed, was this built only by yourself or was it a team project??. just out of interest...how badly were your hands shaking after it touched down?lol. hope you can get the newer twisted blades up and running, they will change everything,any chance of a walk around video showing the fun stuff inside?

loads of questions...cant do them all lol, best of luck in the future with her...p.s.....how many gyros do you have helping your hand-eye work?

[gobyheli]

@robertcoxon

thanks for congratulation. I appreciate this very much.

To your question concerning the project: It's a real one-man-show.

Please watch testflight #4 from 28. of May 2010 and see a tremendous progress with tilting the nacelles up to 25deg.

regards to UK

[Avibeagle]

As others have posted the V-22 is not designed to for forward flight with the nacelles in the vertical position and that is the reason you are seeing the nose raise up as the aircraft moves in a forward direction. As you start to build airspeed across the wings the center of lift starts to move foreward of the CG. Having the flaps fully deployed increases the component of lift. To counter act this you need increased airflow across the horizontal stabilizer.

[gobyheli]

@Avibeagle

Hi,

thats not true.

Nacelles can be tiltes 90deg. forward. Perfect stabilisation is realized meanwhile. No nose up problem anymore. Tilting will be tested this weekend (when the weather allowes it) max. 20deg forward. More I think is not possible because I hav'nt twisted blades for the trust I would need. This is the next developing step

regards

[crazystufffff]

is it just me or are your rotors out of scale?

[gobyheli]

@crazystufffff

you are right. They are actually not twisted. Next step :-)

[crazystufffff]

@gobyheli

Oh cool! have you built this from plans of the real thing, or have you got plans somewehere? also i would be intersted to see in a video the mechanics from your turbine to the rotors! thanks!

[v5dan]

bloody hell that thing looks a handful to control!!! I can see your inputs just to keep it stable hover. To fly a pod and boom turbine machine must be nerve racking enough, but to fly an experimental machine, where you are learning to fly it, well you have balls of steel my friend! I look forward to see your progress. Oh by the way did you think of doing a Fairey Rotodyne, when planning this project?

[gobyheli]

@v5dan

Hi, no eggs of steel :-)

because of vibrations in the right nacelle (you cant see) i was afraid to fly away.

This problem should be solved and I will fly this like my Raptor30 upside down :-)

I know F. Rotordyne but wasnt the rotors driven ba rockets in the tips of the blades? Anyway no project is planned, the V22 is enough for a one-man development.

regards

[lucasjibhi]

thats the coolest thing i´ve seen all day

[TheSabre18]

I want this kind of hobbies since my father bought me a rc helicopter Named "soaring falcon"...im just 11 years old. i really admire your v-22 osprey coz it flew very good and it hovered, to bad i didn't saw or it didn't tilt it's engine it was a really an awesome toy wish you good luck!!!!

[Naturepheonix]

PLEASE HELP ME!!!!!!

I WANT TO BUILD ONE ALSO!!!!

Please start me out with the turbine hobby please?

Please help me out with some good links and models.

[Sweetdancer01]

I would like to build a Osprey. Can you please give me your contact details? Thanks.

Regards from Switzerland, Patrick

[helierez]

goby, the pitching up is caused partly by the rotor downwash hitting the horizontal stabilizer at a certain speed. You could try removing the stabilizer to prove this. As an example the UH-60 has a moving stabilator that pitches up at low speed and goes flat a higher speed.

[TheDarkone1111]

Very nice test flight ... and Very nice Osprey ... you (and friends?) did a beautiful job building it ... it looks great !

[masterflizzle]

Great detail on the aircraft. I'm really impressed.

[airtaxi2006]

did you build this from scratch or is this a kit I can buy?

[airtaxi2006]

Did you make this RC V-22 OSPREY or is it a kit I would like to buy one

[onebadevox]

give your nacelles a small degree of forward angle it should get rid of the up nose affect when try to acc remember this bird wasnt meant to be flown like a heli in full flight so the more you want to fly forward the more you need to start transition the nacelles to keep it level in flight, it will still hover but want to move fwd more, since your running ccpm are your aileron and rudder mixed in with the ccpm so when is in forward flight you get no pitch in cyclic other then collective?

[gobyheli]

this is a very good statement and seems very logical. What 'I would like to know ist if this is your oppinion or expirience? :-)

Thanks for reply

[michaelstanger]

very nice work.

[Rotormast]

Nice work, Would love to see inside. The pitch up problem is common with flybarless heads. If you run twisted blades it gets much worse.  (another story all together) I put a gyro on every axis on my V-22. Not necessary but It makes it flies almost perfect all the time. I get a bit of pitch up in descending flight just as I get back into full helicopter mode, But I have found this is due to me not pulling out enough collective as I break into a hover.

[gobyheli]

Hi,

Congratulation for your project!!

You reached the primary goal to do conversion durign the flight.

Absolut perfect. :-)))

Meanwhile I've 3 Gyros too. I'm sure that flying is a different to your Osprey because the inertia is relativley high compared to your "bird"

Youre right that its primary not necessary to adjust it at every axis.

Would also like to see it inside.

If you like to change expiriences let me know, I'm interested

best regards

Gobyheli

[nakazatoGTR]

you and rotormast are the only serious guys in the RC vtol field.

i hope i get to fly your products in the future

[sierra043]

this thing is beautiful :D

[gobyheli]

Hi

thanks for your reply.

I appreciate that very much.

best regards

Gobyheli

[gobyheli]

thanks.

Ill continue the job, be sure

[pipeliner345]

absolutely OUTSTANDING !!!! guy's!!! this is AWESOME !! work. following closely from texas U.S.A.

[gobyheli]

Hi

Hi

thanks for your reply.

I appreciate that very much.

best regards from Austria/Europe

Gobyheli

[RobMcAnally]

In any case, the sheer magnitude of technical hurdles you have overcome to reach this point leaves me in total awe. This is by far the most impressive RC project I have ever seen. It is one thing to buy a complex kit and do the assembly and flight tests.  It is an entirely a different game to do a clean-sheet, turbine-powered V-22 project. Magnificent!

I assume you participate in an RC forum, if so, may I ask which one? I want to follow this project more closely.

All the best.

[gobyheli]

Hi,

I thank you very much for your reply.

Sorry I'm not present in a forum.

If you have any questions just let me know.

best regards

Gobyheli

[schlusselmensch]

I'm guessing you could have bought a used Ferrari with the money you've put into this?

[RobMcAnally]

I think the pitch-up situation when increasing the forward speed may be from increased prop-wash deflecting the horizontal stabilizer. My guess is that once you progress through your flight tests, you will gain confidence in the flight characteristics. That will allow you to take your Osprey through this transitional, cross-control section of the flight envelop. You should find that at a certain forward speed the elevator will have enough airflow to control the pitch-up.

[skinnywhop87]

Should get and inflight camer for that thing

[pavejim]

You are probably experiencing what we call PITCH UP WITH SIDESLIP. We see it on the aircraft with sideward flight at higher speeds. It has to due with the tail (elevator) and how it reacts to the increased airflow from one side.

BTW, it looks good...keep it up

[gobyheli]

Hi Pavejim,

Thanks for your comment. You're flying the "Big One", am I right?

So doesnt the flight-control-system compensate things like that?

[MSJDesign]

I think the nose up during increased throttle might have something to do with the nature of the fuselage. perhaps the downward airflow flowing off the back to the tail is creating more lift.

[gobyheli]

Thanks for your reply.

Actually the position of the flaps is combined with the tiltangle of the rotor-shafts. 90deg.=max flaps / 0deg.=0deg. flaps. Think Ill try to reduce the position of the flaps when increasing speed

[TheodorKK]

so when will it be able to tilt the engines over for some flight?

[gobyheli]

Hi,

technical its able to tilt forwards.

With the mounted rotor-blades (standard and not twisted) I wouldnt get enough forward-speed. With this non twisted blades a max. angle from 20degrees (from vertical Position can be reached.

I will make the twisted blades when all systems are still working, otherwise I probably would do some work for nothing. So one step follows the next.

Back to yout question: I think that I can show you a video flying with 20degrees tiltangle before xmas. ok?

[TheodorKK]

sounds great! i have followed you since the start ;)
