Using CS-5.4 or CS22BBMG servos in s400
Hello,
I was wondering if either of these servos would be strong enough for a speed 400 plane:
Cirrus CS-5.4 - [link=http://www.hobbypeople.net/gallery/444030.asp]CS-5.4 at HobbyPeople.net[/link]
or
Cirrus CS22BBMG - [link=http://www.hobbypeople.net/gallery/444423.asp]CS22BBMG at HobbyPeople.net[/link]
Thanks,

I think it would be dependent on the model in question. We use these and similar servos in our grossly over-powered and over-sized control surface electric foamie 3D models, but they are slow.

What type of model do you have? Will it be flown slow or fast?
Are the any recommendations from the manufacturer of the model?
There are some programs floating about that suggest the required servo power, not sure how accurate they are... You'll need some basic specifications of the model to use these programs.

It is a Cessna 172 kit that is made for free-flight but can have RC equipment installed in it. So, that is what I'm doing.
I'm not quite sure how fast it will go. Is there a way I can calculate the
speed? It has a s400 motor and I am trying different prop sizes. Someone recommended that I use a 6.5 x 4 prop.
I know of someone else who did this in the same plane and used CS10BB servos but, those are now discontinued.

I found out that the CS-5.4 is even stronger then the CS10BB servo the other person used.
I still can not find info on the CS-22BBMG

I'd go for the 5.4's... They work very well for us. The Cessna is certainly NO beast!
Speed can be calculated BUT like I mentioned it's not going to be fast any way. If you know the RPM the prop turns and the pitch theoretical speed can be factored... The 4 pitch prop is a SLOW prop unless it spins really FAST! A higher number like 10 or 12 is much faster...
