Default Hitec 545 vs 605

Which of this 2 is better?
From what I read, the 605 do not center well but is more powerfull than the 545.
I need to high torque servos and hitec have a
good price. Thanks for your help!!

I would definetly go with the 605BB's, I have alot of these and they have no centering problems, with 77 oz. torque with 4.8volt pack theyre great. Daz...

Default 545/605

The 605 is dual BB, 545 is top only BB; 605 is 77 oz.in. vs 545 62; 605 is .16 sec transit speed, 545 is .22. The only thing the 545 has going for it is it's 0.1 oz less weight, very slightly smaller length & height.

For a couple of dollars more, you better the batch with the Hitec 615mg. I'm using quite a few of them, and it's a darn good servo for the price.

Default Hitec 545 vs 605

Last year I tried both the 545's and the 615's in my heli. I personally had much better results with the 545's. The 615's would not return to center so it seemed like the heli needed trimmed all of the time. Now, for planes, I would definately use the 615's since exact centering is not as important and the control surfaces take a little more abuse as far as extreme stick movement is concerned.

I was thinking of using the plastic one because I read somewhere
that the MG are not that precise as the plastic gears.

That may be true....I dont have any experiences with the plastic gear version. I loved the 615s in my Goldberg Extra 300 with a Saito 150, but in my heli, the machine just wouldnt stay trimmed to one spot. With the 545's, I could actually take my hands off all of the controls while in a hover and just watch it for 5 seconds or so until it started to move. They took all of the aerobatics that I could dish out.

Default 605 hitec

I love the Hitec servos. I use a lot of the 425's in my smaller planes. I put the 605's on my 30% Carden Extra but after 6 flights I could'nt keep the ailerons trimmed. I replaced them all with Futaba 9202's. What a difference. If your looking for precision the 605's don't have any. The 545 is much better at centering consistently.

I didn't notice this on other slower planes but when put to the test on a larger aerobatic plane the 605 didn't perform.

Good luck
Chris

These servos use a three-pole motor geared *way* down. This gives great torque, but lousy resolution.

Lots of heli guys have tried these with predictable results - a machine that won't "lock-in" to a hover. Yuo can search the heli forums for more info.

That being said, I have a set of 615MGs running the tail of my Ultra Stick. They are slow to find absolute center, but are OK in this application as the plane is rarely going in a straight line.

Did not understand your answer, yours 605 or all 605 because they come with mg also.
I am asking because most of the people
that have centering problem are with the mg.

The 605's Im using do not have metal gear. And they do not center well. I've never used the 605 MG or the 615.
