Mum is the word!
I think the 1000 kv is a tad low for a zeph,I would go with 1200 to 1400 kv on 3s and 1000 to 1100 kv on 4s.

Like these.

Or even better since they will pull a little less current and are in a good torque range.

thanks klique. my only worry was that the servos would be too weak too - I had some lying around from the old zephyr and they served me well at speeds up to 250km/h, so I thought I could use them as well for the time being.

since I'm doing a hobbyking order today anyhow for the batteries, I think I'll throw in 2 of these. that was my 50g weight budget, though, now I can't add anything else ...

have you used any of the 2 servos you suggested? a lot of pre-testing goes into using new servos, so I hope at least they center well ?

I got my Zephyr kit on order as well, I'll be using the Hitec HS-645MG servos, as I've used those a lot and they're indestructible.

Right, well, the HS-645MGs can be had a lot cheaper on eBay, I paid $29 for each.

Cheers,

Sander.

I was planning on using these for mine: http://www.servocity.com/html/s3004_...l_bearing.html

They're only 44 oz-in, but I'll probably only be flying 50-60mph. The main reason for using them is because I already have them (and I'm cheap). I've heard they are good, reliable servos. Thoughts?

not metal gear. you can try it, but I'd keep an eye on them. They won't break in flight, but on rough landings.

Mum is the word!
Trap those servos look good .

Aero K Those are really not enough,cheap is cheap till it goes in then its very expensive.
The servos we are recommending are not expensive.
I just find analog servos with not much power will make the wing feel out of trim all the time, the dont hold their center,been there done that.
Servos play the most important roll in my opinion.

Now for cheap these are perfect, http://www.hobbyking.com/hobbycity/s...idproduct=9442
they are not to torquey so the wont draw too much like their 130 and 190 inch ounce brothers.

I'm guessing that it was a tank! Very nice build, but it looks heavy...

Oops, I was thinking Klick's pictures in this thread were the same as an old Zepher build thread. The colors were similar. I'm assuming this new build will be much lighter...

Waiting for more info...
