Update and Advice

[inpar]

Hi Mojo,

I was in your position a few months ago.
I bought a twister 3d, got it home and thought what do I do now, I was scared of it and scared of changing the settings on my DX6i, but don't worry, you can't break it.

In reply to your earlier question about setup, I used Boggys bible and it worked fine, you may well want to change one or two settings as you progress, but to start with use the settings he suggests ... he certainly knows what he's talking about, it helped me no end and gave me confidence with the sticks knowing the heli was setup correctly.

I don't have a sim, so I can't comment on that, but the only advice I will give you in getting the heli off the ground is be aware of the headspeed because it is a very fine line between just sitting there spinning and lifting off ... When the heli gets light on the tg this is where your bottle will be tested ( It did mine and still does ) be as confident as you can with the throttle, by that I don't mean give it lots but be smooth, but be sure to give it enough to lift off and not catch the tg on the ground.

I hope that makes sense... Oh ! and experiment with plenty of expo It's your friend.

Good luck,

Dave.

Your eyes will tell you that the heli is doing one thing when your brain knows it can't be.

Love that

So true!!

Hi and good luck with your quest for heli competence.

Am a newbie too with the mCX and a twister medevac but have decided to build my next heli and have planned a trex 450 and a 500 after much advice form the site anf forum etc

There is a safety warning out about the DX6i. Some versions have faulty control pots so producing erratic transmissions and therefore heli movement from smooth input control movement.

The safety notice and checks can be found at the BMFA website:

http://www.bmfa.org/news/2009/02/03/...sx9-tx-notice/

It seems that bigger helis are easier to fly especially for a newbie.. I have booked some lessons to get me going in right direction.. and if your flying outside a club make sure you have insurance as a country member of BMFA. Membership of a club will include insurance as part of your fee structure.

Good luck

Hi,

Thanks for the info about the fault on the DX6i.. i have done the monitor test and it seems fine..

I have been on the BMFA site but didn't find any information about fees, etc.. However, i'm supposed to go to my local flying club and have a chat with them on a flying day (if the weather gives them a chance) : ) and i'll ask them about their membership, insurance, etc..

Good luck with your helicopter building, did i get that right though.. Are you building 2 at the same time? Good effort!!

Hope it all goes well..

Hi Dave,

Thank you for the encouragement and advice.. I was scared a bit of the twister, the reason being the setting on the DX6i it came with. When the throttle hold is released (and the throttle stick all the way down) it starts spinning pretty fast so i didn't dare move the stick.

I am going to program Boggy's beginner settings into my other DX6i and bind it to the heli.. i would guess it does not spin at the lowest stick position, thus giving me a feel for the response of the speed in relation to my stick input : )

Thanks again and one very newbie question! (what is a tg?)

I am on the look out for some training gear for when i go out on a field, or might attempt making some, but will be starting with RADD's instructions indoors first.

Cheers...

Hi mojo,


tg = training gear, my fault, not a newbie question at all.

Yep I think with Boggys settings your throttle should be ok at low stick, if not you could give the throttle trim a couple of clicks down.

Indoors is ok if you have wood floor, ar at least a hard floor, but indoors be carefull m8, this heli reacts in the blink of an eye.

Training gear is a must, and when you do go outdoors lay something on the ground, something smooth, firm and flat to take off from, because untill you're confident in lifting off with commitment even grass will "trip " the heli over ... ask me how I know !

Good luck

Dave.

Hi, the doomed to failure comment was my attempt at humour. I liked the comment someone made about take off and not being too cautious with the throttle, very true on grass, although if you are on a really smooth surface you can move the heli around without it leaving the ground and keep going like that until you are ready to take off.
Any large bits of ice would be ideal.

The dodgy pot recall is a bit misleading. A pot by the way is a potentiometer. It's got three terminals. The two at each end connect to a resistor and the one in the middle, sometimes called the wiper moves up a and down as you turn it. So if you connect each end to a battery, you can vary the volts coming out of the wiper by turning it. The old name for volts was potential, hence the term.

I checked my DX6i and it was fine, then a couple of weeks later it went wrong and I had no control over my Cx2 and it took off on its own.You can get them to check it over for you by taking it to your local shop. I forgot what to do, but I should have hit throttle hold.

Cheers guys,

And thanks for the insight into the training gear pitfalls on grass ..

I'll make sure i keep it in mind when i do take her out.. I was thinking of building a set of tg but i'll just go and buy a set as soon as i get a chance..

I have put Boggy's settings into my Tx and they work a treat.. i spun her up and on my wooden floor sort of turned her right and left (didn't dare do anything else until i get the tg). However, i can start on Radd's method (with care of course).

The thing that concerns me is that the throttle on my Tx is very sensitive so as i move the rudder there is inevitable changes to the throttle. With the mCX and on the Sim there is no problem as neither have lightning response so i can re-correct it..

Is this a case of opening up the Tx and tightening up the stick travel or is there a programable parameter that would do that?

And i'll take the Tx back to a hobby shop and ask them to check it (just in case)..

Thanks guys for all your input.. Much appreciated..

[Boggy]

you can add a little expo to the rudd channel. that will make it less sensitive around center

[Mojo]

Thanks Boggy,

That will numb the rudder i gather, but will it desensitize the throttle?

Cheers..

[Boggy]

just rudd

Cheers.. Will give it a try!!
