Raptor E550 (30 size) heli tail servo best mounting position?

[BigBadDom]

Looking for some help and feedback on this please: my Raptor E550 has the tail servo mounted on the boom with a sturdy looking connecting rod to the tail. I note however from my Raptor manual that the tail servo should be mounted in the main frame at the front of the heli with a connecting rod kit (PV0043) that runs to the tail.

I'm thinking of converting this back so the servo is mounted on the frame at the front (purely from an aesthetic perspective), but before I do I was wondering if there is a good reason that the tail servo has been moved in the first place: perhaps for less slop/more tail authority?

If anyone has any insight or advice, it would be much appreciated!

Cheers
Dom

You're right, the tail mounted servo kits were generally to try to get a smoother and more direct link to the tail with less flex and drag on the linkage. For electric helis I think this is still the best way to do it. For nitro helis the tail mounted servos can get exhaust residue on them (but so far this has not been a problem on mine). Another advantage is that if you need to pull the boom in or out to adjust the belt tension the servo moves with it.

The other consideration sometimes is C of G but with electric power you can usually move the LiPos around a bit to adjust the C of G.

Thanks for the feedback Trillian. Glad I guessed right for once! LOL.

It only costs about £8 to convert back so I'm tempted to try it especially as I'm only flying gentle circuits currently, so wonder if I would notice any difference anyway. I can easily convert back if I'm disappointed with performance I guess.

Cheers

That has reminded me, I thought it wasn't as purdy as mine mounted at the front, but I do feel a little drag from the linkage.

I know its an old post but when I had my Raptor E550 - the tail servo was mounted up front in the frame - I wasn't happy with the amount of length, flex/slop and drag in the linkage, so using a servo tail mount kit off ebay I fitted it to the tail with a direct carbon linkage... less flex, less slop and much smoother..
