Mini Titan Servo Setup

[Lemmingkje]

Hello,

I'm new to the hobby and I've just bought a mini Titan V2 but I'm strugling with the assembly of the Servos.

1) The tail servo is a BLS257, but it seems to come lower then the ACE Servo that is recommended. This makes that the linkage rod going to the tail rudder touches the rod guides. Is this a problem or how should this be fixed? I read that bending the rod is an option, but I wanted to be sure first.

2) The ball linkage of the tail servo should be installed to begin with at 10.5 mm according to the manual, but 7.5 mm according to the gyros manual (GY520) ... which one should I take?

3) The Cyclic servo rods seem to touch the frame slightly when I attach them on the recommended 12.5 mm from the center of the servo. Is this normal or should I move them a hole more to the center?

Thanks in advance for any advice.

Cheers!

Hi welcome to the forum

1) I would replace the wire tail rod with a carbon rod and remove the original guides, I fitted the Beam E4 rod on mine.

2) Fit the ball at 7.5mm

3) Look at this link on how to space the servo's away from the body Mini Titan V2 - Servo List & other Mods Needed During Build - HeliFreak

Hope this helps

Thanks for the quick response.

Is the Beam E4 rod a hollow one, or does this mean also changing the linkage balls?

I'll try whether I can place the Cyclic servos a bit farther away from the holders. I just thought it would normally fit from the start, since I'm using one of the recommended servos (C1016MG)

The carbon rob is solid and it comes with in a pack of two with alloy ends (with screw threads on them) that need to be glued on, you can use the original mini titan ball links too.

The servo fitment is a pain and I see they have changed the servo mounts on the new V2 SE so that you can fit different sizes.

Nice, I'll look into that. I've also just noticed that the servo horn I used didn't have a hole at 7.5mm, so it was actually 8.5. I've just changed it to the other hole nearer to the center (6.5 mm) and there it would actually fit perfectly, in which case I could just use the guides to begin with. But what is the effect of having the ball link at 6.5mm?

I've also noticed that the cyclic linkage rods are either just touching or not touching. Very difficult to say since it's a black rod on a black frame. Even with a little peace of paper behind it I'm still not sure. I could try tightening the screws of the servo, but how tight may they be? I suspect that tightening too much will render the rubber o-rings useless ... or shouldn't I even be using them?

Hello,

I just wanted to mention what I finally did. I've used the beam E4 rod as suggested by simplyraptor. I've mounted the tail servo the other way around to have the straightest angel for the servo mount without hitting the tail braces.

I've also used Trex 600 balls and rings for the futaba servo horns, since otherwise the distance from the center was too small.

Thanks for the help!

Regards.
