S500 Frame

Hi John the kv is a bit high for a large frame you would normally look at 650kv to 800kv as you need to run bigger prop to get flight times , the motors you have run 7 inch props , your find it hard to get the lift ,
your need to run a 5200mah battery on that size quad even then your flight times will be very short

Thank you hotneil. I'm a little confused as to the size and power of the motors. Are 650kv to 850kv more powerful 1200kv?

If possible could you suggest a suitable motor for this frame?

They are more powerful and spin slower for larger props to deliver more thrust to lift a larger multi-rotor. The higher kv is for smaller props and smaller multi-rotors.

The size depends on what type of flying you will be doing with your 500. What kinda flying are you wanting to do?
 
I fly 900kv on my 500, and can get about 10 -12 minutes from a 5000mah. (Converting it now for larger props for better flight times)

The lower the kv the longer the flight time will be, but know the max prop size for your 500 since it will be your limiting factor.

Here is a video from mine with 900kv.

A truly beautiful video, I loved it! So a 900kv,okay, that's a start. Can I be a pain and ask you if you could name a motor and battery,even prop size, it would save me a lot of time. I buy my stuff from HobbyKing most of the time.
 
Thanks!

Do you have a link to the exact frame you have? I think 2216 800kv, 10x5 props, and 4s 5000mah would get you in the teens for flight times. Multistar 5200 4s 10c would probably be a good fit.
 
Hi John the info from the guys is spot on , I fly a 700 quad on 650kv motors and they spin a 14x5.5 prop , and can go bigger but its getting to big to put any where when I get home lol

I don't mean to hijack this thread, but I am curious as to what are your flight times holtneil? I am guessing a 4s setup?

I've just been to Hobbyking and its there with all the information I need (probably not). I'll look at those you suggested, Thanks for you help.

I LOVE that quadcopter of yours, if I win the lottery I'll get one :)
 
Its work in process at the moment 1 esc has gone down so waiting for a replacement to come into stock or I will have to change all 4 , on a 5200mah I hope to get into 15 mins , but it does not have a gimbal its just a quad so its not to heavy
on a test hover I got 9 mins on a 2200 3 cell but thats a hover not flying in to head wind
 
Here is my favorite reasonably priced combo for the size quad you are building;
SunnySky 2216 800kv motors. Virtually vibration free. Smooth, powerful and efficient
ZTW Spider 30A opto Small ESC's. Operate up to 600hz. Run cool. Plug and play. No programming. Only 11g
Castle Creations 10a UBEC. Very,very quiet. Adjustable voltage. Able to handle more than one device. Can wrap the leads around your antenna w/no problem
12 X 3.8 CF props, Rc timer on the lower end and Tiger Motor on the upper end.
If your arms can't support a 12" prop then use these;

You can get all this stuff from your favorite vendor. Ebay, Gearbest etc.
This combo is smooth flying with no jello. Perfect for video. On a 10c 5200mah 3s battery you can hover at a UAW of about 2100g and lift about 3600g at 100% and still get about 20-22 minutes flight time. I used this on a Reptile framed quad which was 1780g and I was at 27 minutes when my awesome flying skill caused it to hit a building.:rolleyes: One more thing. This is so smooth with the T-Motor props that I had my camera wire tied solid to my frame. The video was perfect right up to the wall impact. Wish I had recorded it.

I like the sound of this, I'll definitely have a look. So sorry to hear about your crash,I hope you managed to repair it.

Haha! The crash was no ones fault but my own. All do to my legendary(read; mediocre) piloting skills. All that stuff is going on a 470 I'm in the middle of building. I have another Reptile style frame I'm modifying to a 620 with 3508 KV380 motors swinging 15x5.5 props. I keep changing my mind on parts of the design. Oh well.
The parts list I suggested to you is the lowest quality I will accept and it IS good. I also have a better and best. I got burned by the cheap stuff when I first began. To finally build a quad that performed and didn't keep falling out of the sky cost me more than if I'd bought the good stuff in the beginning! No more. I decided that I will wait until I can get the best for each build. No more crap. Ever again.
Now, this is only MY opinion and I'm sure you can find folks that disagree. I don't want my multi $, multi pound quad digging holes in the ground unless it's because of my amazing(see above:rolleyes:) flying. Hahaha!! Safe Flying!
 
This is a good discussion on motors and props. I'm still learning my way around how all of the components interplay since I have not 'grown-up' in the RC industry. Now I'm an old fart and memory is a challenge, but I love building stuff. My current build is a QAV500 with some Multistar Elite 720Kv motors (I believe). Waiting for a new compass/GPS for my PixHawk before I can take off. The GetFPV, QAV500 frame - while on the expensive side - is well made and with a long frame, room for just about anything. The aluminum arms are very cool indeed. Great attention to detail for sure! I'm still learning the basic of flying, but want to venture into FPV at some point. Already have the Black Pearl LCD panel.

I have a Yuneec for serious stuff, just want the challenge of building one that can compete on that level - with dead-on hover, GPS goodies, and autonomous flight. So far my experience with Naza M V2 has not been so good. Though no fault of the NAZA. That's a bird I'm still trying to get flying properly. Daylight time is my limiting factor during the week, and clear weather on the weekends isn't always available. :( Plus living in the woods with very little (read no) flat area and tall trees all around is even more challenging, and I don't have the skill to attempt lift-off in my garage! So, I have to drive to an open park, or school and hope there are no ball games going on to perform test flights. Great, fun hobby nonetheless.
