Need Help For Mini-t

[helicraft]

Hi Bro,any one care to help?
Jus got another used Mini-Titan and using my existing DX6i. with same setup .This heli can't lift up when throttle stick move up slowly to the centre position.However,as I move the throttle stick down to zero,the heli fly up suddenly and down again.

Does anyone know wat's went wrong?
Here the setting
D/R & EXPO
AIL 0 80% +30%
ELE 0 80% +30%
RUD 0 80% +20%

THRO CURVE
NOR: 0-30-55-77.5-100
STUNT: 100-80.5-70.5-80.5-100

PITCH CURVE
40-55-71.5-85.5.100

SWASH MIX
AIL: minus 80%
ELE: minus 80%
PITCH: plus 80%


thanks

My guess, your main shaft is not tighten properly, meaning there might be movement up and down.

simple!

either ur blade pitch is the wrong direction or ur blades spinning the wrong direction.

when u throttle up, the air pushing the heli downwards so u cant take off.

u throttle down, then suddenly the air pushes the heli up instead (cause the pitch or direction is opposite) so the heli suddenly shoots up now since the blades already spinning fast.

TADAH!

most likely ur pitch is going wrong way.

i think mini titan swash goes down means pitch goes up because its leading edge control on main blades.

opposite of most helis.

Check your swash mixing setting on your controller. It should be wrong.
On my futaba, Pitch is set with a negative value
Ail +80
Elv +80
Pit -80

Yup, like wat Bro Stickman mentioned. Wrong Pitch. The swashplate going the wrong way.

When u throttle up, the motor starts spinning up but your blades getting to more negative pitch.
When u throttle down, the motor begins to slow down but the blades change to positive pitch. That's y the heli will lift up a little when the motor are still spinning

Thanks to all who responded .
Hi Bros, Yes!!! ,You All are absolutely Right, the swash plate goes the gnorw way. I recalled when I was setting-up TREX-250 the swash plate goes up when throttle up .so did the same way for mini-t. which is wrong.....should hv read the mini-titan manual..its clearly shows when the collective pitch stick is at the lowest the swash plate is at the highest level. wat a silly mistake of mine?


Cheers....
