Need help for setup of DX6i with TT mini titan

[feudallordcult]

Howdy folks, good evening to all.

Managed to borrow a dx6i from a friend a few days ago. need to try it out before buying a 2nd hand from a fellow bro here.

in gist, tried to set up the mini titan but to no avail. tx is already bound to bird.cyclic, throttle, elevator, aileron, pitch and rudder controls are all in correct order. gyro has been set to INH cos I'm still a newbie flying with training skids. swash mix also set at a value of 55. when the motor wires are unplugged, the rx & gyro would both flash a solid red light but when i reconnect the wires then the battery, both rx & gyro kept blinking. bird can still be controlled by tx. throttled up but bird just won't take off no matter how high i push the stick.

I hope senior bros who own a MT could kindly share on the set values. Or is there something that I am just not setting correctly. Many thanks in advance.

Best regards
Meng

sounds like u seriously need to join a funfly with experienced pilots

Hi feudallordcult,

the forum is a place for sharing info and helping each other out, but from your description it sounds like you are not aware of some rather basic setup steps and have missed them out altogether. Hence johndyl is right to suggest you get some face to face help instead. You should be able to get the help of the friend who lent you the dx6i yes?

in any case,

1) your rx is blinking because you have not turned-off your tx since you last disconnect and reconnect the power to your rx, so your tx and rx are thinking that there has been a brown-out and is telling you so by blinking.

2) gyro has nothing to do with your skill level. your gyro is blinking probably because it is working in the rate mode. you need to allow the gyro to initialise properly and also to configure your tx to send it the correct value for it to go into AVCS mode.

3) standard swash mix value for Spectkrum/JR is 60/60/60. Why do you set it to 55? Smaller value does not mean it is better for beginner.

4) you cannot lift off probably because you have not checked and set the pitch to the correct working range. that has actually turned out well because, since you did not mention that you have setup your tail servo correctly and your gyro is not working correctly, you would probably have crashed the heli.

Have fun!

Much faster to learn and understand by going to a funfly.

Possible on self-learning but can be daunting, depends on individual.

Always good to read more, go funfly and ask. Speeds up the learning curve.

Alot of gd info.

Look under Heli trex450 build videos. Not the same heli but concept is the same. Understand the purpose and it can apply to many types of heli.

Do note on the swash and pitch relationship. The Trex and mini titan is the opposite, use a pitch gauge and you will understand.

search for finless bob videos on youtube to understand the pitch setup

As for GYRO setting, it is actually the gain setting and it cannot be inhibit. that's why u get gyro lights blinking

Rx blink is no issue if u can control ur servos. The rx thought a brownout occured since power was cutoff and returned within 30 secs. Thus it flashes to indicate brownout.

I assume ur blades are swinging but then its not taking off. Then it is a problem with ur pitch setup... you need to go into ur dx6i and set to pitch swash mixing to -55

Many thanks to all

HI all, my heartfelt thanks to all who contributed solutions to my heli. it's finally lifting off. now it's the setting of the gyro n i should be able to fly a great bird...with training skids attached of course.

[feudallordcult]

Chums,

finally got the reverse & swash mix in order to get the new bird to take off but it's very strange that the swashplate actually moves down instead of up when I throttle up & vice versa. when i flip the idle up switch, the swashplate moves up.

when the bird is powered up, the canopy tilts forward and does not keep level.then the tail just keeps spinnning when throttling up. I have checked the gyro settings and set it to 30% at Nor & 72% on HH mode.

should there anything else that I should be checking? and any advice on how to rectify the spinning?

Many thanks in advance.

tail setup

MiniT is trailing edge pitch control, as opposed to leading edge ptch control as commonly seen on Trexes, hence the opposite swash travel. Just a different system.

canopy tilts forward at spool up probably because your swash is not level at neutral tx position. use of a swash leveller will help. sounds like your servo sub trim has not been done right. typically swash has to be levelled before pitch setup is done. so after you level your swash, you will need to recheck your pitch setup.

tail spinning out of control? are you spooling up on HH mode? is you tail servo travelling in the right direction, does it need to be reversed? is your tail rotor even travelling in the right direction?

All helis have some offset even if u have a perfectly level swash, so just trim the tilt off for a start. Other things u can do is to shift your cg to coincide with the main shaft.

I presume your tail spinning is only during the spoolup proccess, if not you wouldnt have been hovering This happens in rate mode, so just fly in HH mode. If that also happens in HH mode, then you need to increase your gain (under GYRO in TX)

Many thanks

I will remove the linkages off the titan and redo everything all over again. hopefully will make it this time. thanks to all for the advice. Many cheers.

Update

In the midst of the learning how to set up the MT, i also tried my hand at the e-flite blade 400d.

when i first bought this bird from a fellow brudder, my thoughts of this bird was only so-so. all the rave reviews abt this blade sounded a little too good to be true. in addition to buyer's remorse, only skyhobbies carried the spares and there weren't many left. when i did my first hover, i had this niggling feeling that i was screwed.

so i searched the net for info and there was an avalanche of info for this bird...fortunately. however my personal experience wasn't that fantastic like what the others expressed.

so i bought 3 hi-tec hs65mg servos and changed the gyro to xm hobbies g401b and the tail servo to hyperion 12dcg. then i bought the honeybee king 2 feathering shaft and replaced all at one go. so after setting up the electronics and all that jazz(minus tracking),I also finally got the chance to catch up with my flight mate, Ameen to fly tonight.

My thoughts on the blade 400d: it's an absolute dream! I am not kidding. It's so much more stable than the MT but taking into consideration that the MT was flying with 315 blades, i prob shouldn't expect too much on the latter.

I seriously didn't do much after the blade took off and it steadied to hover. there was really nothing much for me to do save for aileron and throttle control. in short i'm delighted to say that the blade 400 is a grat bird to fly and should anyone see it overseas and there's a discount, i'd say GRAB it at first instance. really no regrets.

btw, the settings indicated by horizon hobbies didn't work at all for me so a tiny obstacle would be to set up the bird yrself. other than that, just enjoy this wondrous bird.

i learn hovering with the blade400d when i was overseas, but after coming back to singapore, found out that there are no shops carrying spares except for skyhobbies. i was hovering it with stock electronics. it was a handful just to maintain hover. crashed it one day and didnt bother rebuilding it. decide to go for more main stream heli in the future.

well, i had the same experience as u when i first received the blade in stock condition. it was to say teh very least. with a somewhat decent gyro (clone) and new servos, the feel is completely different. anyway, it's renowned that the stock parts of the blade are crap.

Wonder....

I'm just wondering the thread by Heli_fanatic useless? The whole thread covers everything from alot of helis to Basic setups to reviews to headspeed calulators!! And still we getting threads which people still ask alot of questions which can really be solved by watching a video on helifreak,
I am not saying this thread created is wrong, im only just wondering is the thread created to solve all these problems(Basic setup Problems) useless?

well, it's definitely not a useless thread or at least not to me.

it's also my appeal for help to senior members who are helpful & willing to share. in fact, it was through this thread that I learnt abt finless bob videos and subsequently learnng how to properly setup a heli. and I also got plenty of help esp from Bro minipilot who made the learning curve "less steep". Thanks Alex and all those who offered advice.

whilst there are plenty of sites (helifreak etc) that offer a one-stop solution, one may not easily locate such resources or information.

Hence in future, when someone new to this hobby appeals for help, i would definitely share to the best of my knowledge albeit being extremely limited at this point in time.

To perhaps answer if "this thread created to solve all these problems(Basic setup Problems) useless", it is an affirmative NO. This cannot be used as blanket thread to cover all issues pertaining to basic heli setup.

Simply put, there are quite a number of variables to consider when setting a heli. It's easy to spew terms like reversing, setting gyro gain& limit, dual rate, expo, travel adjustmts and many more (i am still learning!), it's the directions that senior members have pointed to me which enabled me to gain more in-depth knowledge for this deeply enriching & satisfying hobby. Not forgetting it's darn expensive.
