9g Servo's?

[NewZee]

Hi All,
My first post here, I'm halfway through building my first swappable. (FT Spitfire), have a qquestion about servo's the build video shows the crew using 9g servo's my LHS only had 5g (HXT550) so I bought them? I thought the control surfaces are not too large and are lightwieght foam. Any thoughts if the 5g sevos will cause me any grief? thaks in advance for your insights.

I think for most of the flight test foam board planes, 9g's are overkill however it doesn't take much of a bump to kill a 5g servo. Just keep an eye on them, realize 9g's are in stock at Hobbyking again and order a passel for future projects.

Your profile doesn't mention your location, so I can't suggest another source.

All I know is that Josh specified 9g servos, even with the FT Nutball and FT Flyer. And knowing how cheap Josh claims to be, I would think that if a 5g would work, he would have used them.

On the other hand, I've never tried to use 5g servos on any of the swappables, so I don't know for sure that it won't work.

Not much of an answer, is it?

Not really knowing, I'm going to say that your lucky you shop had those. My hobby shop only sells cars and heli's. the only servos they sell are high torque copter ones that are $20 for 2.

Thanks RoyBro, I'm in Western NY (Near Buffalo) I have the 5 g's intalled so I'll see how they work and reply back once I know.

Thanks MrClean! I'll let you know how I make out! I'll get the 9g's when I need to replace them. (might be soon):black_eyed:

Thanks Nathan, I am pretty lucky LHS is 4 miles from home and has been in business 60 years are RC flight specialists and have lots of gear!!! just a little pricier than the big internet supply houses.

There is not even a town within 4 miles of me (Closest Model Shop is 80 miles and they don't do much electric at all). Parts have to be shipped in but I am in uncontrolled airspace as a BIG +. FAA says first come first served (whoever is flying in the space first owns it till they leave).

Servos are cheap. Buy a bunch.

If you are in the US, you can get them from HK's local warehouse in a week.

Here's a good economical 9g servo.

For heavier use/high dollar planes, buy a metal gear servo:

Because of their popularity, you can get a 9g servo cheaper than a 5g. They're the real workhorse in the RC world.

I accidentally bought 5gram servos for a plane that was supposed to have 9gram servos in it. It wasn't even that big of a plane. It was the $20 Cub that Hobby King sells. I crashed the plane and completely stripped out one of the servos. On one of the very first flights. 9gram servos might be 'over kill' but 5gram servos are a lot weaker and are only really needed, or wanted, when weight is a big concern. Like micro planes. Definitely get some 9gram servos. I've never had a 9gram servo break and one of the two 5gram servos I used broke almost instantly.

Thanks I'll definately go with 9g on all future builds and when the 5g's fail!

I agree 9g's are the way to go, but for what it's worth the 5 g's worked we'll on the maiden flight of my Spitfire!!

I agree that 9g's are the way to go, but for what it's worth the 5 g's worked well on the maiden flight of my Spitfire!! So I'll leave them on till they break.

I believe most people use 9 gram servos with foamies because they are cheaper than the 5 gram servos. I have seen 9 gram servos used on some pretty large foamies, so a 5 gram servo is probably even better for a smaller foamy if you are willing to spend a few extra bucks.
