DX6i setup for Trex 450

[Davy Crockett]

Hi folks

can anyone help a numpty please?

DX6i tx arrived this morning and need advice setting up for Trex 450.

I have managed to bid the tx & rx . . . so far so good!!

everything seems to work but when I apply throttle the head speeds up and when I go past mid-stick it seems to push down?

with my neon blaze, as I increase throttle it lifts off, and i can hover.

I realise the trex is a different heli, just want advice so I can set up the DX6i and know its right

many thanks

not sure on the setup but sounds like you need to reverse the swash from +60 to - 60 and then your model will go upwards
the swash on a trex 450 should move upwards for positive pitch and downwards for negitave pitch

[sacko]

Yup, I reckon you got it in one

Check it with a pitch gauge.

Have you selected another model memory on your DX6i or are you trying to use the one associated with your neon blaze?
As the others have said it would seem that the pitch is going in the wrong direction.
Up for positive pitch, down for negative pitch.

Also make sure you activate Throttle hold then you dont hurt yourself...

the blaze is on a different tx, one that came with the heli.
all the helis i have had (medivac,blade cx2,blade msr) all take off with increased throttle and thats all i know.

maybe its my being a novice but i thought i could set the DX6i up to be similar and then change as i progress.

sorry if im missing something but as i said 'a numpty needs help!!'

however, i realise i wont be inverted tomorrow, i'm doing something i've wanted to do for 20 years and want to do it right and appreciate all your help/comments

Here's some good HeliAddict info on the subject.

Googling "DX6i setup 450" will get you a load of links as well.

The Finless videos over on HF cover most things but his 450/TX vid uses a DX7 as luck would have it, for you.
They're still good watching though.

Check out this link, all people have there own preference to how they like there Heli to be set up but this should get you started

As already said in one of the posts, set up your throttle hold so that when you flick the switch if you move throttle by accident it won't start the motor, I learnt the hard way and had a 450 start on the kitchen table when I was messing around with settings and the bloody Heli shot up into the celing

thanks for all your help fellas.

spent 3 hours trying settings and heres what happens...

F.mode switch at 0

left stick up - swash fully fwd
left stick down- swash level
left stick left - tail left
left stick right - tail right

right stick up -blade tilits down (back of blade) generates lift??
right stick down -blade tilts up
right stick left -swash tilts right
right stick right -swash tilts left

switching F.mode switch to 1
as above except
left stick up swash fully fwd
left stick centre swash level
left stick down swash fully back

sorry if i'm missing a trick here but I am SOOOO confused!!

with the motor disabled


the channel reverse and swash mix may be different so to set these up first follow this quick guide.
set throttle hold or better still disconnect the motor then

move the throttle stick up and down. all three servo's should move together,as you raise the stick the swash should rise. as you lower it the swash should fall.( if there is a problem go to the reverse menu in the set up list and alter the pitch/airl/elev servo's till they all work together correctly.

now the right stick.
stand behind the heli.
each movement of the right stick should move the swash the same. eg forward tilts the swash forward etc. if you have a problem go to the swash mix menu. you will see the 3 values set with either a + or - %
if the swash tips back instead of forwards change the value of the elev mix to opposite what it is now set at(eg from +60% to -60%)
if the swash tips right instead of left change the airl value to opposite.
if the swash tips at an angle when you apply forward stick change the pitch mix value to opposite

spent all afternoon learning!

thanks for the advice, heres where i'm at....

reset model in tx and set up as boggy's post, when left stick up/down, all 3 servos do same... brilliant!

but now controls on right stick are all reversed. if i reverse servos in reverse menu, then right stick controls work, but left stick is reversed!!!!!
and if i change the values in the swash mix menu, i'm back to square 1

[Boggy]

as above davey get the servos working together first then if the right stick controls are completley reversed change the airl % and elv% in the swash mix menu to opposite what they are now so from + to - or vice versa

[Davy Crockett]

Boggy, you're a star

think the rest of the setup i can sort

just got to learn to fly now!!!!
