Title: FPV 250 Quads
Post by: sihinch on January 18, 2015, 09:22:56 AM
I thought the Star Wars style FPV 250 Quad racing looked pretty cool in Zoltans video. I know there was some chatter about them, so I thought I'd start a thread to see if anyone is going to build/buy one.

So, anyone got plans to get going on an FPV 250 Quad?

Which one? What components? What's influencing your choice?

figure it will be a good starting point :)

Looking at them on YouTube and they're cutting leaves and running into trees.


I don't know they have no appeal for me.


Good luck with it.

There are two well brand outthere.

http://www.minihquad.com/

http://xhover.com/

Their frames are durable.  The only thing that possible to break are the props.  Both have their suggestion in motors, controlboard, setup.

For others who not familiar with building the race quad, you can try the RTF version from Helipal.

well it's official i joined the dark side (see what i did there ;) )

I'll post a build thread once i get all the parts but for now I've ordered:

Frame:

ESC:

Motor:

Controller:

Planning on getting the quad flying first before i worry about a FPV system (but welcome any recommendations.)

Also i welcome any comments, questions, or concerns with my choice of components.

Way to go, Greg!  I just can't quite pull the trigger yet - I'm not 100% convinced it's what I'd like.  As I've said before, I can't really fly a quad (at the moment!)


But if I did, I would go for similar frame, the same ESCs, but the Multistar Elite motors.  They have a 3mm shaft, I didn't like the 2mm shaft on the regular Multistar ones.  But what do I know!?


I'm excited for you!

Cool Greg! Do you think it will look more cool with led lights added at the front and the back, like green/front, red/back?

Title: Re: FPV 250 Quads
Post by: battlestu on January 21, 2015, 12:30:18 PM
for sure red leds will be on it (if i'm keeping with the dark side/star wars theme)

Oh heck Greg! Robert guilted me in to ordering tonight!!! He said I "can't start a thread saying 'hey this is cool' and then say 'yeah, I'm not sure about getting one!'"

So I decided to take the plunge!

Similar spec to yours (same ESCs and similar flight controller, K2.1.5) but different frame (low hung clean-and-dirty!!!) and motors (multistar elite 2300kV.) Also no FPV gear for this quad yet.

Like you, I will start a build thread. Now I'm excited !

Go Greg!


Still waiting for mine.
Title: Re: FPV 250 Quads
Post by: battlestu on February 13, 2015, 08:55:23 AM
Attached the motors to the frame. Wired the ESC, BEC, and lights to the power distribution board. Also started to clean up some of the wiring (still more work to do ;)

With some luck i can have it ready to fly this weekend... now if the weather was a little better

Nice progress!   :)


Mine arrived last night, will un-box tonight and post photos of parts.....
Title: Re: FPV 250 Quads
Post by: Papa on February 13, 2015, 10:18:39 AM
Greg, did you solder that distribution panel or did it come already soldered?


Jack.
Title: Re: FPV 250 Quads
Post by: battlestu on February 13, 2015, 10:32:53 AM
Hi Jack...it had some bullet connectors on it but i removed them so i could get the board to fit in the pocket of the frame.... i know it's not my best work but i'm going for durability :)

Hi Simon...can't wait to see the pictures!!

Greg
Title: Re: FPV 250 Quads
Post by: Papa on February 13, 2015, 11:44:36 AM
I wasn't being critical. It just didn't look like mechanical soldering and I wondered if it was sold with the buyer having to do some soldering?


Jack.
Title: Re: FPV 250 Quads
Post by: battlestu on February 13, 2015, 12:47:30 PM
no worries ... if your only going to connect ESC to it you can get away with no soldering but if you want lights, voltage monitoring, fpv, ect you'll to break out the iron.

But there is tons of bare PCB to work with:

Post by: sihinch on February 13, 2015, 10:00:14 PM
Here are my bits. Just need to work out what to do with them! I got the frame with the "low hung" accessory frame with vibration damping. So it'll be a little different than Greg's.
Title: Re: FPV 250 Quads
Post by: battlestu on February 14, 2015, 09:54:16 PM
well... test hover is complete and it's still in one piece :)


I still have some drift i need to tune out but i got some time before spring gets here.


Greg

Post by: Ededge2002 on February 15, 2015, 06:34:26 PM
What is this "Drift" your talking about?

Mine wont qualify for the 250 class but I too am building something that has multiple motors!
Title: Re: FPV 250 Quads
Post by: battlestu on February 15, 2015, 10:03:51 PM
Just needs a bit of trim.... I'd take it outside and fix it but Ill wait for better weather


Very cool Ed .... And feel free to add some more build photos

ImmersionRC is releasing the 250 Quad in RTF.  This comes with the vtx built-in.  All you need is the FatShark goggles.  Interesting to see is the special design EZUHF r/x for the QuadCopter.

very neat idea with the motors (just use your finger to set the rotation CW or CCW)
Title: Re: FPV 250 Quads
Post by: sihinch on February 20, 2015, 04:02:50 PM
That IS awesome.  Speaking of motor direction - which way are they meant to spin, on the 4 corners of the quad?



Title: Re: FPV 250 Quads
Post by: battlestu on February 20, 2015, 04:46:01 PM
i used the default setting on the KK2.1 controller

Very cool...be sure to post any build pictures when you can


Greg

Post by: fearless on February 23, 2015, 07:28:26 PM
Will do Greg.  I was wondering if you used connectors for the esc to motor or did you just solder the 2 wires together?
Title: Re: FPV 250 Quads
Post by: battlestu on February 23, 2015, 09:28:10 PM
No connectors for the power into the ESC (soldered the wires to the power board) but I did use the bullet connectors for the three phase outputs to the motors


Greg

Awesome I'll see what i can come up with once mine get here.

I finally got round to looking in my Quad box. That was scary! At least with an aeroplane you know where a wing goes! The box was full of screws, rubber balls and random plastic plates! I shut the lid again!

After searching google images and a bunch of other forums and quad blogs I managed to start piecing together how it was assembled.

So I took a deep breath and started to build last night. After 2 hours I had a frame with motors on it! This morning I connected the ESCs and flight controller so I just had programming and set-up to do.

With the help of YouTube and 30mins tonight I had a Quad that was ready to test. I rushed on to our back deck just before dark and successfully completed my first hover!

It was a fun build and it all went together really well. And seriously only took me 5-6 hours. Now I just need to tidy the wiring and add the FPV gear!

Pod racing here we come!

Hi Simon
Is your Quad airborne yet?

Title: Re: FPV 250 Quads
Post by: sihinch on April 08, 2015, 03:28:57 PM
Yeah! It flies great - much better than the little quads I've flown. But the limitation is the pilot! Infact I crashed it today!

just saw this on horizons web page:

http://www.horizonhobby.com/mach-25-fpv-racer-blh8980

but at $430 I'll need to start saving my pennies :)
Title: Re: FPV 250 Quads
Post by: sihinch on April 09, 2015, 12:28:12 PM
Looks s****y, I like it.  But very pricey and only a 25mW transmitter.


Wonder if they may do an "ARF" or "PnP basic" version?

I just saw the working prototype in Toledo yesterday. Also spoke to one of the developers of this unit.
It actually look a lot better than the the picture. They are using aluminum arms, carbon fiber body and got castle creations to create a single ESC that will handle all 4 motors.
One of the very interesting aspects is that the CG is towards the back rather than the typical central CG most people use. He was saying that they feel they can stop faster and have better straight runs because of that. Something I will have to try with my quad!
