The Mini Titan Thread

[BloodClod]

Hi,

Anyone using Kong power 2200 batteries in their mini titan? I installed a pack to find that it makes the heli slightly nose heavy. I'm wondering whether I should add some weight to the tail to balance it out.

I'm just moving on to rolls so I'm concerned if the slight nose heavy condition is going to affect my flying. Should I leave it as is, add weights or get lighter batts?

thanks.

The last thing to do is to add weight.. Have u tried to shift the battery up on the tray? I'm using a 2500mAh battery which weighs heavier then the Kong Power by about 10g but im not having much problems when doing forward flights and rolls.. I guess abit of nose heavy helps in forward flight as Mini Titan tends to pitch nose up while flying fast forward flights..

Sharing this tracking experience with everyone.

Last night I changed blades and did my blade pitch adjustment. This morning when I flew, there was a minor tracking issue. No matter which direction I adjusted the link, the blades were still out of track.

Upon closer examination of the head, I found out that one of the screws that screwed the mixing level to the seesaw hub was a bit loose and therefore caused a slight side-way wobbling of that mixing level.

Once I tightened that screw, it removed the slight wobbling of that mixing level. After that when I spool up again, the tracking was perfect

Hope this is useful to someone

Think it's better not only tighten it. But locktite it..
Best is to tighten it without any linkage attached to either end to have a better feel that it is firmly tightened and not overtightened.. Cos I found that overtightening it will cause restriction to its movement, and u can't gauge if any of the linkages is still attached.

this is yet another prob with the mT..

do make sure that all screws are tight(with loctite) periodically, they tend to loosen themselves more quickly on the MT

usually, even if u supertighten it, it should not bind because there is a bearing on it.

if it binds, it is likely that locktite has gotten into the bearings and u'll have to take that piece out to clean it or change the bearing.


when applying loctite to areas where the screw has to pass through a bearing, use a toothpick or thin stick to apply inside the hole instead of on the screw thread..

Hmm.. wonder y mine is different from urs. Mine does bind when I overtighten it for both sides. I discovered that before started using locktite.. Probably cos mine is plastic?

oh that could be it also

Some of the places have a small washer which the bearings ride on. Remember to put those washers on, or else you can't tighten the screws without causing binding.

And yes, I do apply thread lock on all my screws which go into metal parts. But some how that mixing level screw became a bit loose. Important thing is to go over the screws before each flight

thanks. I tried shifting the batt up in the tray but it was still nose heavy. Not very off balance. I've read that a slight nose heavy balance is okay (some say better) for aerobatics?

[Brandon Chng]

the binding that happens when you tighten it down so much is not because of the washers. i run mine without washers so i can tighten it more securely. the reason for the binding is that once you apply the force on such small bearings, the bearings become notchy. these are radial bearings, not thrust bearings, so when you tighten the screw down, you exert considerable force on the races and balls. this effect seems lesser when you don't actually use the washers. there is no problem of the outer race rubbing the non moving component.

What kind of cyclic angles should I be getting from my swashplate? Just moving into mild aerobatics so I want to make sure my setup is sufficient.

Thanks.

for the MT try 7deg first.. if not enough.. 7.5 then 8

[john_3330]

Yup! As what johndyl has said, try out 7 degrees first.. I always have a crazy thinking that if the heli is nose heavy, it'll move away from me automatically, so in case anything happens, no one will get hurt.. But that was only when i started hovering.. Recently found out that if nose heavy, while doing invert nose-in hover, the heli will come right at u!

So it depends on what kind of feel u are looking for.. I personally like nose heavy.. But now with the 2500mAh lipo, its TOO much nose heavy..

[BloodClod]

Will try 7 degrees to start.

thanks.

I'm still practicing my inverted nose in on sim... be a while before I actually try it on the heli.

Did my first loops today... not the prettiest but the heli came out alive so I'm happy. No success getting it to loop properly on axis, hence my question about swash angles.
