Collective and Cyclic Servo Speed
Does the faster servos on collective and cyclic management make a huge difference e.g. 0.12s vs 0.22s servo.

I am practising tic-toc in my sim and that manuever has a high demanding on the timing. I notice that 0.12s and 0.22s servos have a significant difference. I can do the tic-toc much easier with the faster servos that the slower ones. But what about in real world? Should I upgrade all my cyclic servos to the high speed ones?

the fastest servo in the world won't help if it doesn't have torque, to back it up.

There has to be a balance between speed and torque.
Hell... I can fix that.
Uh oh..
Nope.

I agree for tic tocs a fast and powerful servo is alot better.

What heli is this for?

but can I still do the tic-toc using slower servos?

Very nicely put. Sometimes people forget that there are trade-offs for speed. You can't have it all

I can't do tic-tocs but I have seen a lot of people fly and I have found that whether or not a maneuver can be done lies squarely on the pilot's shoulders, not the heli. Well as long as the heli meets basic needs. I watched a guy fly an old MA Fury that was big and slow but he flew everything he wanted with it including tic-tocs, things just happened much slower. Actually it was fun to watch because he had to seriously watch his collective management and that forced him to time things well and take things slow. That shows skill by the way!

I think you should give it a try and find out. I mean what is the worst that will happen? You won't pull it off and have to bail. No big deal. Then you will know.

One other thing to point out, are you running your servos at 6v? If no and if they can be, run them at 6v and that will not only speed things up but also give you more torque. Then if you find you want more, you can spend some money. And btw I am really liking all the smaller Align servos so I too would highly recommend the 610s.

Oh, yes.

When I first started trying tic-toc, I did it on my Raptor 50 with .20s servo. It worked, but since it took more time for the collective pitch to reverse, my tic-toc had bigger arc, or as other may put it, the heli dip deeper into each side. The problem with larger arc is it will take more energy to "push" heli back in opposite direction. So, you better have a good motor that is well tune and blades that doesn't twist and soak up the motor power.

Am I missing something. In my book, that's a slow servo for heli use. 0.13s @ 6v is roughly twice as slow as JR8717. I believe JR8717 also have about the same torque.

You can do them with slow or fast servos just the timing will vary. The faster the servo the easier it seems to be.Chris

.13m/s is pretty fast for me.Maybe your flying in competitions but my flying skills will never be able to out-preform the BLS series of servos from Futaba.The brushless series from Futaba are defintely high-end electronics.Some guys can have the quickest car on the road and never win a race.Sometimes the speed in some 3-D manuvers is all in the sticks not necessarly the speed of your servos asm!MAAC#77677 Medicated daily for your protection

I don't fly competition, and I used to feel the exactly the same way as you do now. That's until I had a to chance to fly .10s servo.... Let's just say, tic-toc become easier, much easier...

Now, if you your servo arm can't move as fast as your Tx stick, it obvious become the bottleneck of your setup.

Once your abilities have required servos that have a speed difference of .03m/s to make your flying preformances look tighter and faster your at a top-end level of flying.You can have 8717s running the vitals on your helicopter but with inproper techniques being applied to the sticks its going to look slow and sloppy.MAAC#77677 Medicated daily for your protection

Faster servos will make it easier. With slower servos your going to be holding yours sticks out longer so it won't be as instant with faster servos, but it makes it alot easier when you get faster servos.
Lighter paddles will definatly help too.

Making it easier can also make it much sloppier and mask other issues. If you can do a maneuver with a slow machine, then you really understand what and how to do that maneuver.- Chris

Thanks everyone. I think I will stay with a slower servos first to practise the tic-toc.
