Any Good Heli Set Up sites on the net?

[LipolyGone]

Hi guys
Is there a website out there that covers details such as pitch setup & tail setup, would be handy to have a section on gyros & gyro settings also.

After failing to learn to fly proper helis a few years back & jibbing out, I've decided to dip my toe back into this pool of torture.
I am flying a hummer V3 at the moment which I'm doing sort of circuits with at an indoor venue, not exactly hard core I know but I scared myself witless with IC helis & little micros arent quite so intimidating for me.

I have now purchased a Trex 450 which I've fitted out with the align motor & speedo combo, an apogee 1700mah 3s1p lipo, a GY401 & HS50, HS65's every where else.The hard part for me is going to be setting this little beast up because I dont have a clue. I'm at the point where the heli is ready but the heli pilot isnt sure & last time I tried setting a zoom up it hit the bedroom ceiling after a frantic session of setting up the tail. I have however learnt to never reverse the throttle at the TX when the heli is thrashing around in a very fast piro on the bedroom floor
Any help or advice would be gratefully received guys.

Ta for now

Try the Electric Helicopters Beginners Guide (EHBG) which you can find at:

why trawl the net when if you ask then someone on here they will probably be able to give you a solution. You will probably get more than 1 answer some may make sense some may not!

So fire away.

Try http://www.rcheliaddict.co.uk/ loads of useful stuff on there

You'll probably find lots of stuff you'll need at:

But as Biggles says - there's loads here too.

Ok what pitch setup would you recomend for a Trex 450x & a newbie who can hover & do a very dodgy looking circuit with a hummer V3?

Do I need idle up 1, 2 & 3 or can I just set it up on 1 setting?

Would you recomend I just set my TX & gyro for HH only?

What throttle setup would you advise I use? is it best to set it like 0 25 50 75 100 for idle up 1 or should I just set governor mode on align speed control?

Ive also fallen foul of having no throttle hold set in the past what is recomended for a micro heli regarding throttle hold & pitch set ups.

So many questions to ask which is why I felt it unfair not to do at least some of the leg work myself.


Ta in advance

I'll try and answer some of them for ya slopey...

Ok what pitch setup would you recomend for a Trex 450x & a newbie who can hover & do a very dodgy looking circuit with a hummer V3?

I'd go for something like +9 to -4
You can set the heli up for +/- 9 to 10, and then use the normal pitch curve for +9 to -4 in normal mode.

Do I need idle up 1, 2 & 3 or can I just set it up on 1 setting?

You can use as many idle ups as you wish. Its fine to start with just 'normal' mode. People set up their modes depending on their flight styles and personal choices. I use normal for startup and hovering, and idle 1 for forward flight and mild aeros.

Would you recomend I just set my TX & gyro for HH only?

nope. you need to trim the model in normal mode then switch to HH. You should not carry the model around in HH as it will try and yaw to correct your walking. Then when you take off it will yaw abruptly. Carry it in normal, switch to HH when ready to fly.

What throttle setup would you advise I use? is it best to set it like 0 25 50 75 100 for idle up 1 or should I just set governor mode on align speed control?

This depends on you ESC. If it has a governor, probably best to use it but they all work differently.

Hope this helps for starters. There's more knowledgable than me regards micros and pertty much everything else for that matter

Thanks for that jimbob
thats enough for me to get started on my setup.

Didn't realise the bit about HH but makes pefect sence now I think about it.

What throttle setup would you advise I use? is it best to set it like 0 25 50 75 100 for idle up 1 or should I just set governor mode on align speed control?

Generally speaking, you set a flat line throttle curve for ESC governors.

based on that, I would suggest the following 2 throttle curves to get you going.

Normal: 0 85 85 85 85
Idle Up 1: 90 90 90 90 90

If the headspeed is too little at 90, up it some more. If you're using an Align ESC, don;t go up to 100 as it needs a little headroom to allow the governor to work effectively.
If you have a Kontronic Jazz ESC, that headroom is built in to the software, so you can go all the way up to 100 if you need to.

I recommend setting the governor as it will give you a constant headspeed with which to fly.

Which ESC do you have/intend to use?

SA mistake often repeated is flyign with too low a head speed. The heli is sluggish, unstable, and the tail hasn't got enough bite.
Aim for 2200 rpm for first flights. You should not go over 2400 with wood blades.
This seems like a vey high headspeed compared to a fixed pitch micro or larger nitro heli.
you need to power up the heli in HH to initialise the gyro or it won't work, and switch back to normal to carry it out.
Alternatively just toggle out and back in to HH before takeoff to reset the HH direction.

If the rex fly's anthing like the Ark 400, if the head speed is just afraction to low, it will 'nod', which is a rythimic smooth up and down motion of the nose.

[jimbob]

I just upped my headspeed to 2400 - what a difference that 400rpm makes on the Trex!

Now up it to 3000 (as long as your on carbons) and then you might be able to catch me

I've got carbon mains but the tail carbons were so knackered they were making tail shake! Can I go to 3k with plastic tails?
