It's fixed ! I am a stupid moron !

[D.Yeo]

I'm a stupid idiot goodness it turns out my hornet tail troubles were all due to the gyro/ servo system after all goodness now the tail is so steady !

i'm damn stupid- i happily installed the servo arm at one hell of a cock geometry which not only gave it an insane amount of throw but gave it an exponentially rising rate which took the gyro outputs and made them really big mechanically.

dont know if anyone else was as stupid as me, but if you got hornet tail wagging problems try a smaller output arm length and a more straight servo arm pull.

goodness i'm so pleased i feel like crashing and breaking it just to make myself calm down.

Well judging from your look....ooops.... better not..... anyway "Your Hornet" belongs to Ah Tai right ...thats why ...... I don mind bringing to the nearest rubbish chute for you. what time and what place?


Joke aside .... Can you just help to measure the distance from the center point inwhich the horn sit to the point inwhich the push rod is connected...... not sure u get what I want....

oh yeah haha ! forgot it's not mine damn.

i get what you mean, the control arm length right?

dont have it with me now but it's 3rd hole down from the outermost location on a standard pico arm.

i still have enough throw and the tail is not only keeping still, it's also behavin very well.

Haha! Glad you solved your happy hornet syndrome.
When I first build it I did the same thing, placed the linkage in the outermost hole thinking ahhh... super fast response... yeah right... turned out to be super fast wagging!

The closer the hole is to the servo the higher the gain and the more resolution you have for the tail. I even drilled another hole beside the inner most hole and it was even better

Like the way u mounted the servo.... It reminds me so much of an Eco 8.... ehehehhehe

[D.Yeo]

hey ray, you mean the servo on the boom?


I'm really pleased with it. scary thing is i think i now understand how people can spend hundreds more adorning their hornet with funky cnc hop ups.....it's a real money trap where the victim not only finds himself spending huge amounts of money into a tiny toy heli, he has to note how he's doing it willingly and happily.

[Super-Hornet]

Hmmm!! Dark side of Hornet force are strong I sense. Don't let your anger cloud your judgement.

anger?
quite the contary now i'm so happy with it i want to spend even more on it arghh

Batteries are charged... electronics are working..... gyro activated........coiling antennae wire

Hahaha super fast wagging haha ! yeah man we both did the same stupid thing!

but hey at least you didnt put the servo arm at the extreme angle i did.....that was what killed my tail.That was the royal cockup

Hmm I'm quite happy the way it is now , i was thinking i didnt want to limit my pitch range on the tail too much otherwise it'll start to feel pretty dead, how long is your servo control arm ?

[Fit]

I just did a major cock up all along causing my crash yesterday

My tail servo was slowly dying and finally burnt itself out yesterday. It chose to die on me while I was like 3m up (smart servo!)

On my gyro I have this thing called travel limit and I ignored that and didn't realise that my servo hits the ends of the tail travel causing binding. All this binding finally took its toll and burnt the circuit board out!

Lesson learnt: If the gyro has a travel limiter, use it to prevent the servo from travelling over the mechanical limits. Then use EPA/ATV to adjust piro rate.
I didn't limit servo travel thinking my piro rate would be slow so I just set my EPA's until I got the piro rate that I want and ignoring the fact that my servo is binding..

We have a blackhawk down...blackhawk...Ah.. Hornet II down.

Don't scare me leh.. I haven't started my Hornet II and now the Micro-Heli Ace pilot crashes his chopper already.

Not pilot fault ah , mechanical fault hahaha!

Will atv on the TX affect the output of the gyro or only the servo?
a bit curious about that....never got down to checking it out (busy flying bleh)

so how did you get the servo to go beyond it's throw range? through your gyros atv or tx atv or a deadly mix of both?

[Fit]

From center of the horn screw to the center of the pivot hole is 7mm. Its as far in as my horn allows.

I don't know how to explain it but the ATV seems to affect both.... maybe this will help:
http://www.futaba-rc.com/faq/faq-gyros.html look up on how to adjust piro rate.

I got it out of its travel range through both the ATV and the gyro' limit.
I didn't really pay much attention to the limit on the gyro. I was ignorant about the ATV's and stuff and just wanted to put in more stick time than tweak time.

With 100% ATV's I couldn't get enough piro rate with the servo limited. So I ignored the limit and set my ATV's till I get the piro rate I wanted (which binds the servo).

Then after I read the FAQ above, I realise what I've done wrong.
