E-wings - a new UK based EPP wing manufacturer

Ouio ok

Ha ha, sure, I'll take that as a pre-order request! Won't take any cash just now till I'm happy with the product though, give me a few weeks to get everything finalised and I'll make a post with the kit contents and final cost including shipping.

I should still be on target for £70 kit cost for forum members (+shipping) but I think I'll need to retail a bit higher outside of the forum, the build costs are creeping up with each refinement!

Lol. Um no idea on that one! May have replied to the thread from my pocket!

Cheers, I had thought of that but I've got most of what I need now, I'll be working in batches to begin with so once the first ones are out I can order more materials for the next etc.

I kind of purposely went all in, I figured that if I stretched myself it would force me to make it work! :P Bit of a risk but hey-ho, you only live once!

're the spars- can you use 2 or 4 spars of 4mm instead of a single large one? see how the price affects it?

But I believe people are moving away from a single central spar and more towards v thin spars directly ab9ve and below eachother. Saves weight, use cheap spars (and fibreglass perhaps to help the rf pass through) and I suspect it's stronger than a big central spar system.

I would go for 1 4mm central (if That!) and 2 spars above and below each wing would probably be more than enough

It's also easier to balls up a central spar imo and then the wing isn't straight

[Badlands]

I agree - forming an 'I-Beam' configuration with 2 x thin spars makes the wing SUPER stiff.

Its quite EZ to do too - just cut a nice straight line & push the spar in.

Cheers guys, yeah each wing has 3 strip spars, 2 in the leading edge, 1 in the trailing edge. The wings are super stiff with this configuration, there's no real flex at all. The 4mm spar is to attach the wings to the fuse (and each other) though, and to make sure you get the correct alignment. I did wonder if I could use strip spars for this as well, it's still an option.

It is a bit of a headache really to get right, I want this to be as straightforward a build as possible so trying to hit the right balance of pre-configuration and what the customer needs to do themselves. I know most people here would be fine cutting their own spar slots but also a lot would be a bit daunted by that.

Not really what you asked, but hopefully the below is relevant

You're entering a tough market imo. What % of fpv is quads and what % wings? 99% is quads imo.

Remove the off the shelf drone phantom sales from the above- you're diy wing can't really be compared to off the shelf products- and you're left with the enthusiast sales who don't mind doing a bit of diy. Of all these "enthusiast" sales I suspect 90%+ of them are mini quad sales.

So- as a % of the market- you really are selling to 10% of fpv flyers- not 90% of them.

You also have fairly strong competition. Ritewing and high end DIY airframes. £££££ and very time consuming build. and £30-60 banggood wings.

How you choose to price and place yourself in the market is up to you. I would suggest a few promo videos of mountain surfing, cloud surfing (in a legal country of course) diving under trees and racing 6" above the ground would make a great selling video.

However- if you want to half compete against the banggood stuff- making it super easy to build would be a damn good start. This IMO means having every slot and groove pre cut for essential components. perhaps not tx Rx etc- but certainly spars and perhaps battery bays etc. If this plane needs half a dozen spars glued in- hot wore a 1-2mm groove in the perfect places (super quick after you have built a jig!) would just make building easier for customers. It also makes them ballsing it up less likely- so your product doesn't get blamed when it doesn't fly straight.

Again- I point to the success of the tbs cap- and say it was successful because it was as straight forward as a wing build could be so appealed. I have never seen a wing review where the builder said "I wish it was harder to build".

Maybe you want to keep buyers options open- and so won't cut grooves for tx Rx gps etc, and that's sensible IMO. But spar slots are well worth it imo!

Doing this on my own, I have some nice CAD software for wing design so I've been using that to define the wings. I've had some advice along the way from various people on the design but it's my own labour of love! :D

It's more dense than the flyingwings stuff I've experienced, I've only used Ritewing moulded stuff but I'd say it's pretty close to that in terms of weight and density. It's super strong, I'm really happy with the quality of it.

I have a few plans with motor mounts to try before deciding on the final option, I'll update on this when I'm closer to release. The angle will be fixed based on the mount so you shouldn't have to mess with it.

I think this is probably true, but I much prefer the look of black EPP. My foam supplier can do white also but wouldn't mix batches so I just went with black to begin with. For the stabilisers do you mean the small fences on the wing or the large central vertical stabilisers? I had considered doing these with correx but I much prefer the look of the V-tail. I may still experiment with others and can laser cut correx so it's not out of the question, but I wanted to avoid it looking like I'd just copied the Ritewing design to be honest, and I like the look of this just now.

Designing alone? What fun! Happy Flyers made some design mistakes by all accounts- but I'm sure you know what you're doing :)

Glad it's dense and black EPP. FW stuff is a bit misleading imo. I'm used to the old school rite wing stuff.

Motor mounts from the flyingwings feel so rubbish imo. And a heavy crash changing the angle of the fuse throws them off. Ritewings latest mounts are pretty great imo. IBCrazy seems to use similar to flying wings.

I was referring to the large central stabilisers. Agree with you not wanting to copy Ritewing. Perhaps the race versions will need some large stabilisers of some kind?

A v tail and forward swept wings is def a unique look!

Hi Rob, thanks for this, will drop you a mail!

[iwan_canobi]

First two kits heading out to beta testers, hoping to get some impressions on the build and get the flight setup finalised asap!

[Badlands]

Oh very nice - does it have a name yet?

[FPVSteve]

Call it the Bazinga :)
