Kit question

[Zec Richardson]

I have just ordered a kit from China, I know they will be Chinese copies of motors but it's a cheap way to start and I can then build another quad over time with better items

 

[Mike]

What is your question? Pretty much every motor is manufactured in China, even the good ones.

 

[Zec Richardson]

Sorry, I spent a good few days looking at a kit and couldn't decide but in the end I went for it.

Its based on a 525 frame as I want something stable, I know for sure I couldn't cope with those small 250 racing quads, even watching a video makes me dizzy.

Is it best to solder ESC or use connectors?

 

[ringolong]

It always best to solder, but I have been using bullets on the last few builds.

Good choice, but it may be a little scary starting out so big lol. I think you will love a 500mm. I really enjoy mine.

How about a link to this mystery kit?

 

[Zec Richardson]

This is it http://www.ebay.co.uk/itm/231508589366?_trksid=p2057872.m2749.l2649&ssPageName=STRK:MEBIDX:IT

I don't expect great quality but for a first build it will help me to learn

 

[Jackson]

Looks decent. Get more props now, some different colors for the front vs. rear to help with orientation would be advisable.

Also get a USBasp, KK2 specific so you can update to some Steveis FW.

Have you flown quads before?

 

[Zec Richardson]

I did plan to get more props, I know I will wreck plenty.
I haven't flown quads before, I have been wanting to build one for a couple of years and building it is something I am looking forward to.

What is the update?

 

[Zec Richardson]

Can anyone advise me on what battery to use for this set up?

 

[ringolong]

I run 4000mah - 5000mah 25-50c 4cell on my 500. The time range is 8 - 12 minutes of flight time with 900kv motors.

Those motors are 2-3 cell. You could use eclac to figure out what would work best for you.

[Zec Richardson]

Thanks, so the 2200mah I was looking at wouldn't be much use.
Is it best to use 3cell rather than 2 then

 

[ringolong]

I would go with a 3 cell, but ecalc is failing on every combination I checked for your setup.

I run 2216 motors on mine which are a bit larger so I really don't know what battery to run on yours.

You could check with the seller for recommendations. Thats what I did for my first build.

 

[Zec Richardson]

All they said was 2s - 3s, I did a search on Google for X525 and tried looking for a similar build

 

[Jackson]

Thanks, so the 2200mah I was looking at wouldn't be much use.

A 3s 2200mAh (lighter) will be provide for zippier sport flying , but short run times. You could then also a get a larger (heavier) mAh battery for lazy longer flight times. You need to match the plug that comes with your kit. Labeled as either Deans or T-plug.

These appear to be the motors, made by SunnySky. Actually a decent budget motor.

We see Max amps @ 10.5. A battery like this is a good compromise (weight vs. runtimes) to get you started.

That one works out to 115A (35C rating) available or 29A/motor and it has the correct connector.

 

[Zec Richardson]

Thank you

 

[Zec Richardson]

I was way out, I was looking at 5000mah and 6000mah batteries.

Will a 2200 give me about 8 mins?

 

[Jackson]

NO. As I noted at about ~180 grams for the 2200 (which I didn't quite recommend, just noted it's advantages) your quad will be at it's fastest and most acrobatic and the motors will not have to work as hard. Short times but fast speed. A 6000mAh will weight about 2 1/2 times more ~ 480 grams. That will affect your speed while lowering your thrust to weight ratio.

You'll need more than one battery. With one, if something happens to it you're SOL, bad cell bad wire, things happen. 2 of the 3300mAh I linked to will cost less than a single 6000mAh, and you will have a backup.

That said maybe you will be happier with just longer flight times, may as well well get a 5000 and 6000mAh.

Good luck.

 

[Zec Richardson]

two of the 3300 it is then.
Thank you for the help, it is appreciated

So I have flashed my board to the latest Steveis and I'm going to order some batteries and a charger tomorrow.
That means that it will get its first test flight next week, I can't wait and yet I'm nervous.

Haha, taking a couple hundred fragile bucks into the air has that affect.
