MiniRaceWing

[Schalonsus]

Just a bit of advertising, i hope it is ok:

Two friends of mine started a Kickstarter project. Its a race wing, called MiniRaceWing.
It has a carbon fuselage where you can put all the electronics and is save when you crash.
The wings are detachable, and if you crash they detach themselves and this absorbs the most force of the crash.

I fly a prototype for a year now and i'm really impressed. Nothing broken yet, even if it took some good beating over the time. This concept leads to flying low and fast, chasing your friends around the fields and trees.
With the modular design, you can also make or buy your own wings and easy mount them to the fuselage. With the ability to easy adjust the COG and thrust angle you can make nearly every airfoil flyable.

I would recommend this wing also for beginners, because its really extreme crash tolerant.

Just had a look at the playlist, I really like the concept, it looks like it works fantastically well !

Nice little wing.

I think it's a fantastic idea - I need to watch some of the videos later.  Does come in quite pricey though, but there's a lot involved in getting all the tooling sorted.  I like anything that portable.

One genuine question.

Would you prefer for your entire airframe to be superdurable (like a laminated EPP wing) or have just the centre section be durable and have replaceable wings?

I see this is a good concept, but to me looks like an evolution of the old monkeyblunt plywood centre section that was around a few years back.

Except this time it's made out of carbon fibre and way pricier than many mini race wings out there.

From my point of view, durability isn't the issue as I never ever crash :)

Actually, I was looking at it from purely a portability view.  I take my 1m Falcon wing on holiday sometimes, it's flat and goes in the car ok, but the sticky out bits of the winglets, antennas and stuff means I'm always having to be quite careful with it.

I like the centre section idea of putting all your components for the same reason - take the wings off.  To be honest though, I'm sure I'd bet equally happy with a flying wings.co.uk version that did the same... as it would probably be cheaper.

Being able to move the CG is quite a nice touch though isn't it.

I suppose so, but only if you plan on using different size/weights of LiPo

If you build a wing properly you don't need to move the CG.

As for the sticky out winglets, make them removeable. cut some thin balsa/ply to the shape of the airfoil at the end of the wing, put a captive nut at the front and back, then glue the ply on. Then you just screw on the winglets.

I did similar with my EPP wings, however instead of captive nuts on ply, I would hot glue a plastic raw plug into the wing tip, then just use a matching length screw to attach the correx winglet.

I'm not saying this wing is bad, I'm not dissing it in anyway. Just think they've come up with a solution to a problem that didn't exist... or at least had already been solved in other ways.

If you build a wing properly you don't need to move the CG.

I agree, normally you'd layout your equipment before deciding where everything needs to go, where to make cuts etc.  My point of view was that you'd have limited ability to be flexible when all your equipment is in a thin centre section, so being able to shift the CG slightly means there's never an issue where you have to consider adding dead weight at the nose/tail.

Clearly you're not a fan, which is fine - we'll just wait for you to diss it relentlessly for a year and then buy one *cough* mini quads ;)

[BlueFlyer]

Haha, I'd like to see these relentless disses.

But you might be right.

[Schalonsus]

I'm glad the most of you like the design.

Does come in quite pricey though, but there's a lot involved in getting all the tooling sorted.  I like anything that portable.

You are right, the moulds for the wings and the moulds for the injection moulding parts are the expensive stuff.

Would you prefer for your entire airframe to be superdurable (like a laminated EPP wing) or have just the centre section be durable and have replaceable wings?

That is the trick of the MRW. If you crash the wings are released from the holders and this process absorbs the most energy from the crash. So the wings and the fuselage are not harmed. I crashed this wing uncountable times (yes, i crash often, but not because i'm a noob in flying wings, but because it makes such fun to chase your friends low to the ground through the bushes, and with +100km/h speed sometimes your reaction is to slow) but i had not to replace anything yet. So i would assume this can be called "superdurable"

1. then you are not flying fast and low enough :D
2. yes it is very portable
3. i like this too, because i have two sets of wings for this beast. The OEM ones and a set of homemade 1.2m. The OEM i fly with 3200kv 4.7x4.7 prop around 700W and the homemade ones with a 1200kv 8x8 prop around 400W. Both with 2200mAh 4S LiPo.

We are going to test a 6000mAh Li-Ion 3S battery to see what long-range capabilities this wing has. The pack is made out of INR18650-HG2 so one can fly full throttle without risking the battery.

I suppose so, but only if you plan on using different size/weights of LiPo

If you build a wing properly you don't need to move the CG.

Or if you are using different wing sets. One slow flyer and one speeder e.g.

Hello Everyone!
I'm Markus one of the developers of the MiniRaceWing.

First let me say, that we had a lot of feedback about the price and we decided to change our strategy and lowered the price significantly!
Check it out!

About the MiniRaceWing itself: You neither damage the fuselage nor the wings in a crash.
Crash, pick up the wings and the fuselage, reassemble and you are ready to fly again.

That's the twist ;) but that's not the main feature. The crash resistance enables you to fly really close to the ground and try difficult stuff without the fear of damaging your plane or equipment.
Because all the components are in the fuselage we were able to design the wing like we wanted. Thin, for high velocity and efficiency. It is also extremely hard to tip stall. Combine this with the shape, big area in the center small area with high aspect ratio outside, and you get an exceptionally fun flying wing.  Agile, fast and on rails in the tightest turns.

Enough of me talking ;) If you have any questions feel free to ask!

Regards,
Markus

Hello Markus, welcome to FPVHub

[Ratty]

With a wing racing league starting this year in the UK, i wonder if this will be the answer to the durability worries i have.

Look forward to seeing some of them on the circuit.

[Loopdreams]

Presumably they'll have all sorts of rules relating to size and weight etc, though so I guess it'll depend on those.  I think what I like most about this design is that the prop is well away from the trailing edge so it shouldn't make that absolutely godawful noise that most wings do.

Hi Markus,

I'm liking this idea a lot... but with your project only around 20% funded with nearly 50% of your kickstarter time gone, do you have a plan about what you are going to do if you are *not* funded ?
