Rudder servo

I've done it!!.

Last week I finally bought the Raptor 30 V2 KIT. In fact, I have bougth a bunch of screws and other small pieces. We'll see if they become a helicopter.

I have one question for you. I still haven't get the radio, servos and gyro. I have been adviced to get the Eclipse 7 from Hitec and Gyro GY401 from Futaba.

The question is about the servos. I can buy the Eclipse with 4 servos in a pack. I dont known which are the servos but I think they are quite simple (and cheap). I have to buy another additional servo and it can be a better one to be used to control the rudder. Futaba S9253 is the one adviced to join the gyro.

Is really important to have a faster servo to be used with the gyro or it can be a cheaper one as the others?. Any suggestion about this subject will be welcome.

Hi Vicente

First things first all the wonderful high speed and high power servo's will not make much difference to being able to fly a heli or not

Now I have got up the purists noses there are some things that you can do that will cleary make a difference

I have a 12 year old Moskito that is original with woody blades and Futaba 148 servo all round with a 154 mechanical gyro. This was what I could afford at the time. It still flies well and will tolerate light aerobatics but more than that will shurely kill it.

What I am saying it is not a requirement to have top of the range to enjoy flying. A modern gyro with heading hold option is to some extent an advantage. all of the kit can be upgraded to meet the needs of your flying style. I have seen new/training pilots arrive on site with more money in the electronics than two helis would have cost, but still had the woodies on.

Sorry for the rant, I will continue below

I need more space.

The GY401 is a very good gyro and to be able to do its job needs a servo that will respond quick enough to the command inputs.

All manufacturers make one servo in a range then gear them differently to get more or less power at the expense of some speed compromise. Digital is different in that they will usually have enough power to snap a composit arm when stalled and are very fast and accurate. Great for very aggressive flying styles, also for those out there who have pockets deep enough. This includes me I will spend money on a new heli engine or gyro without a blink but when the phone bill arrives, do I moan?
Happy landings

So I understand that would be a good idea to use the faster servo to control the rudder, combined with the gyro. I will have to break my piggy bank.

Thank you very much for your help.

Best regards.

I would start out with a standard gyro (piezo, but not heading lock) to learn how to keep up with the tail. Why? If you get a heading lock gyro first, and it fails you won't know what to do!

Also- use a standard gyro for the tail for now. The high speed ones are only needed for the heading lock gyros because they can and do move much faster than you would or could.

Stick with JR or Futaba (for the radio). Airtronics is cheaper but you'll end up paying for it in the end (lack of features and durability). JR is the biggest name with the most compatible equipment. You could get a JR transmitter and all Hitech receiver/gyro/servo equipment. This will give you the features of the good radio with the price savings of the Hitech equipment on the receiver end.

JHP is 100% right on the ball.

A correctly set standard gyro will give you all you need for learning and good positional sense it will also allow your heli to feather when you are in forward flight

Happy landings

hi vincent

if your budget is realy limited i still have my mechanical
futaba bb it might be the 154 ..works great...
i have 2 gy 401 now so don't need it anymore
can trade you for a few anya 3 glow plugs
