Here's a video of my Hornet that was taken a while back .Iam going to do another which will be better.

Dam! Another vid for the collection
Rinsing the moves. How low can you go... millimetres!

What's the total AUW, Duzi gear ratio, paddle and blade choice?

Hi DarkHorse1

Auw have not yet checked
Duzi main gear and 13 tooth pinion
Std paddles
Weighted MS Blades

Flying a Hornet really becomes fun when one gets the nack of these small machines and there setup.

The Duzi flying style must come standard with thier upgrades.

That's some great flying. I'll look forward to that next Vid.

wow man that thing has got power, what batteries are you flying??

Mine is 370 gram auw and i fly tp1320prolites but it hasn't got near as much power even with a greater headspeed

Blade-x the link seems to be working just fine only left click on the link and on the file at gigashare.

I am using thunder power 1320 batteries and 13 tooth pinion although it goes like a bat out of hell one is limmited to the amount of pitch one can pull and if you over pitch it will seem slow and slugish,keep the headspeed up and not to much pitch and all works well.

I will try to post a better one in a few weeks,this one is a bit old.

Thabks for the response guys.

What's the pitch range on it?

It does have get up and go. But so do all the Hornet 3d vid's I've seen. From what I remember, the Duzi Hornet videos star a bloated pig of a Hornet, and that thing's still got some serious spunk for something that small.

The DUZI hornet two 'only' weighs 350 grams which was alot but compared to all the hornet x3d is rather light as most tend to be in the 360-380 grams.

Mine is 370 grams and i fly with a maxir maingear glued to what's left of the stock maingear one way. (goal was to achieve even higher headspeeds for testing what the max is on 3s with readily available pinions)

It's got 120 teeth and i fly it with a 18 tooth maxir pinion 18/120=0.15

i believ the duzi maingear has 88 teeth 13/88= 0.147

so my headspeed should be a fraction higher then yours.


That's why id like to know your auw, if it is significantly less, it might prove good to put mine on a diet (decasing the RX and soldering all the leads directly to it etc..)

Hi Jonnyb

Not sure aout the pitch ,i set it up to fly as i want it to fly however at full pitch and full cyclic it must not loose to much headspeed.

Mattijs

It's got 120 teeth and i fly it with a 18 tooth maxir pinion 18/120=0.15

i believ the duzi maingear has 88 teeth 13/88= 0.147

so my headspeed should be a fraction higher then yours.

Actually a lower gear ratio gives you a higher head speed but the two ratio's are so close it does not matter.
The only thing i removed was my receiver casing .

Get your machine to run nice and smooth and use good batteries and fly the hell out of it , i ballance every thing that is possible to be balanced, like the head,blades and tail.

Spinout, watch closely , the ratios i calculated are inverted.

18/120=0.15....if i'd go to a 19tooth pinion (upping the headspeed)
the calculation would be 0.159.

So, my headspeed should be slightly higher, you are right ofcourse in saying 0.147 vs 0.150 isn't enough to be seen though.


I did some climb outs after some tweaking at the tail (it had a little wag in hard 3d moves...i'm trying to do tic tocs etc)
but it seems that the removal of the slop in the system didn't solve it so right now i've come back to a 17 tooth pinion (0.141 gearing).

I'm hoping it will perform more like i remember it from a week ago and before.

I think at even higher headspeeds carbon tailblades might work better because of their stifness but it's too early for my to conlude anything.

Okay i see what you did with your ratio's

Are you still using the standard belcrank on your tail that comes with the H2 ????

I did a mod there i will post a pic in a few days when iam back home.
Yes technically carbon blades should be better.

I like to keep the head speed up then the tail holds better as well.

yeah, i'm using the stock bell crank as it worked very good up untill now

It develops slop after a while but i fixed that.

Great video.

Is there a specific training route to learn to be able to fly this way? Like learning inverted hover in all orientations... then circular flight in all orientations upright then inverted---> DFLipping... ? Or do we jus "stick it" once we know invert and can flip?

Apologies if I sound brainless. Because I'm jaded about what training path to take. (Learning to fly 3D on a Hornet 2 isn't exactly idea, but I'm sure it's cheaper coupled with suitable sim training.)

I haven't been able to stick to a sequential training plan myself. I said I was going to when I started, but I just bounce around following whatever interests me at the moment. I can blame my ADD for this.

When I feel I've got a trick pretty well nailed on the sim then I'll take it to the H2 with lots of altitude. The squirrely H2 never feels quite like the sim so it takes me a few attempts at first.

Just keep doing it at safe altitude until it's ironed out, then start bringing it down to where you can actually see it.

I'm learning 3D on an H2 also. I don't think my Shuttle would hold up.

Problem solved, turns out the kok blades i used before (i used the stock ones for the ultra high headspeed tests ) make the tail perform better.

i am flying those now again on 3200 caclulated headspeed.

What also contributed was that the kok's need a little hogher pitch for the same climb so i was stalling the stock blades after going back.

I even lowered the pitch some more and it's really smooth again through all the manuevers

I flew today on very high winds and the tail performed flawlessly (not perfect becuase of the wind but it didn't wag when jerking the collective)

turns out the kok blades at the headspeed i'm running it at are capable of real tic tocs... not those sissy archy tic tocs i've seen in the eric larson x3d video but actuall 45 degrees to 45 gedrees tic tocs.

I'm thrilled as i didn't even know the hornet could do them, i certainly haven't seen any as good in any videos before


I'm gonna try a 20 tooth i think but i might use safety glasses at first.
3500 HS is scary fast and i've never heard somebody doing it on a hornet....never heard anybody do it at all i think.

*****Apologies if I sound brainless. Because I'm jaded about what training path to take. (Learning to fly 3D on a Hornet 2 isn't exactly idea, but I'm sure it's cheaper coupled with suitable sim training.)*****


I've learned to 3d quite well and i've never extensively flown any thing other then a hornet.

I've never flown a nitro or anything bigger then the hornet for that matter.


I think it will take quite some time longer on the hornet but if you fly sim enough the sky is the limit.

I'm flying about 19 months now but there have been atleast 5 of them where i didn't have time or something.

On average i don't think i've flown more then two packs a week average.


I'm starting to be good at 3d, i can do alot of cools things with the hornet.

Start with loops and short periods of inverted hover but only do so when you not only can manage an inverted hover on the sim but also are capable of turning it inverted in flight and stop it to a hover on the sim.

The braking is important as it proves you will not pendulum swing the heli if it gets unstable.

> not those sissy archy tic tocs i've seen
:lol: your killing me. We must see yours soon.

If you want more accurate head speed measurements without a Tachometer:

With a PC microphone record/sample the low frequency hum from the rotor (at say 44100 samples per second). Then using a audio editor (such as SoundForge) you can measure and calculate the time per rotation by marking and measure out 2 cycles per rotation, for 2 blades passing in samples:
( ((44100) / (2 cycle sample length)) x 60secs) = rpm.
