Hey guys I just went out to fly the mini titan after doing some tic tocs and some inverted hovering I brought it back in for a landing and it started shaking in the air, the blade tracking was spot on but it was shaking so I landed and inspected it and I don't see anything wrong with it. It was flying fine through out the flight in idle up but in normal it started shaking? Any ideas?

Maybe the gyro gain setting in normalmode?
Mine also shakes a little in lower RPM's, once I'm at 60% throttle they are gone.
Could be many things though IMO, or a combination of things...
Bend Mainshaft, blade balance, ball links binding, Gyrosettings, tailservo, paddle alignment, bad ESC, etc.etc.

My tail doesnt wobble at all, could a slightly bent flybar causs this? When I first got the heli my battery went dead on me and I crashed it, didn't break anything not even the blades because I was low and going slow but the flybar was slightly bent so I just bent it back by hand. I'm pretty sure it did not hit hard enough to bend the mainshaft but I will take it apart and check it.

Most likely the flybar, or paddles slightly out.

Thanks guys I will pick up a new flybar tonight and see if that takes care of the problem. Its weird how it works fine until the end of the flight when I take off it doesn't wobble at all.

They wobble at lower headspeed, you can lubricate the dampeners like you would a larger heli and it will help but when your battery is shot and your head speed is lower you will get a case of the shakes.

I will take it out and land it in idle up and see what happens.

If i leave it in idle up its fine so thats what i have been doing
Are you still still using the stock main rotor hub?This might be the problem

Stock everything except for metal mixing arms.

The stock rotor hub where the main shaft is insert might have enlarge over a period of time.Trying to a new one.And it don't really cost much too.

hi, i also have this wobbles on my MT when im doing hover or stick less than 60%. sometimes when spool up, i experienced lost of take off power also....is it due to the stock esc?

I don't have weak take off power just the wobbles but I would guess its a battery problem. I'm going with an all metal head soon so I will just stay in idle up til then.

I have the shakes at maxed out head speeds. I'm ordering a metal head this week.

LoL we just cant get consistency can we. What head are you ordering? I'm probably going for a dragonus CNC head.

The Dragonus head is very nice, a little more complicated than the standard head where the blade grip mixing is concerned but nothing nasty.

GForce head for the MT is VERY NICE. I've got one coming after seeing two of them at our field.

I'm sure it is very nice but its just to bulky for my taste.

Wobble could be happened if damper is deformed . The tail rotor could lost balance if it is damaged / dents . Also, the metal servo mount can cure the weak points of the plastic main frame, where has a big holes on it .

The G-Force head can fit the plastic seesaw only . I heard that they are making their own metal seesaw . I am hoping to see it soon .

At this point kasama seems like the better way to go IMO.

me too. My concern is does Radix blades fit it? I've heard no but they should.

Why wouldn't radix blades work? I dont think a company such as kasama is going to make blade grips that wont fit 1 of the most popular blades on the market, just my opinion though.

I heard that the grips are to tight measuring 4.3mm or 4.4mm The Radix measure 4.5mm I'm about to buy both and we will see for sure.

Do they fit?
