What multirotor to build next?

[Crash_Expert]

Hey guys!

So I have a Titan tricopter that I've heavily modified into a mini-tri and want another multirotor.

I'm thinking a quadcopter since I already have a tricopter.
I have the wood to scratch build one but I don't know if I should go for a racing quad or a full size quad.
The racing quad would look like the one Josh was flying in the Argonay video.
I want it to be able to carry my GoPro for FPV etc.

Any suggestions on what motors and such to get?
I'm really clueless as to what is out there in the mini-quad market for electronics.

Should I even make a racing quad or should I make a normal quad?

Any input would be appreciated.

Dual Copter or a single copter! I am thinking about the same once i get my Tx Issue fixed.

 

[Crash_Expert]

I can already 3D helis.

I'm trying to decide on a full size quad or a mini quad.

Well the mini craze is the thing right now.

Exactly...

So that is what's pulling me in that direction.

But is it worth it?

A full size quad costs about the same as a mini doesn't it?

A mini quad or hex around the 250mm size is definitely more fun to fly than a 450mm or larger. But they can't lift a whole lot past the bare essentials of a small camera and a Vtx. A larger multirotor can do an FPV gimbal. . . .articulating lasers. . . ultra bright lights, etc.

Twitchity hex... /thread

 

[Crash_Expert]

Hmmmmm
A hex.
Didn't think of that.
It sounds like it would be a ton of fun.

I want to use a 3s 2200.
What can give me the most flight time?
I get 4 minutes with my current setup, 4.5 if I'm lucky.

I get about 8min with a 2200 on the hex

What frame?
Motors?
ESC's?
etc

Psst ssteve, make sure you recommend a KK2

Well if you can already 3D helis, I'd definitely go for a racing quad. LOS flying a slow multirotor is boring compared to a CP heli (my opinion). A different story for the quads that have the performance of FinalGlideAus, I've seen a few videos from him and it's absolutely different from a CP heli, you can do different kinds of aerobatics (3D if you will) compared to a CP helicopter.

FPV is a different story obviously. If you want to go FPV I guess you can tame down the quad before you actually race the thing.

So it depends what you want to do with it. Reading back my own thoughts, go with a racing quad (with KISS ESCs! )
Unless you want a camera ship with gimbal.

Twitchity hex frame, dys1806 motors, naze32 acro, rtfquads fire red 12a esc's, and genfan 5030 props.

With those props I am very aggressive on the throttle to get it to do what I want, and I just tested out some 6" props that allow me to fly with far less constant throttle inputs so I am thinking it will have a positive effect on flight times. This setup could also easily carry up to a 3300 3s as well.

The ONLY time I would do that is if he didn't own a computer lol... Actually scratch that, I'd download baseflight on a computer at the library to avoid using the kk board.

Thanks for all of the input guys.

Is it just me or would a racing quad cost about the same as a normal quad?

The price of parts on a medium sized quad are generally in the same neighborhood (part for part) for a mini-racing quad . . . but from what I've seen you'll pick up slightly nicer parts for the racer for performance, vs. it's a little easier to cut corners on the copter with a bigger weight budget.

I suppose you could cheap out on parts for the racer and gain a small advantage, but after the performance cuts, it's just a mini quad and not a racer . . .

That's the best part. You get more fun for the same amount of money. In the end it costs less for breakage and such though.

My thoughts were more along the lines of why pay the same amount for something small when I can go bigger for the same price?

So you would rather pay porsche prices for a school bus?

It all depends on the end goal. For me, a small, agile, fast flying quad that wont destroy itself in a small crash is worth more than a larger quad that's really only good for hovering around and capturing video. Don't get me wrong, I see your point, and I own both, but in doing so I can tell you that the fun per dollar amount is much much higher imo with the smaller quads or hex's. particularly if your flying fpv.

The direct price isn't always reflected in what you see on your initial purchase either. Bigger means heavier, which means bigger batteries, more expensive props, harder crashes etc.
