E-Wings experience

For almost a year I’ve had a chance to fly FPV wings designed and made by Ewan Harwood from E-Wings – Scotland based pilot who decided to make his own aircrafts and sell them to masses.
I have built and flew every single wing Ewan has designed and also I helped him with beta testing. In this article I will put my thoughts on each of the wing to shed some light on their flying properties and so on. Let’s get started!

Vortigaunt (Vorti)


This was my first E-Wings creation purchased as an upgrade from AR Wing which reached it’s limit of crash resistance ha ha (see my previous post for details).
It is 1200mm big bird with generous fuselage holding compartments  for components and large battery, both of which are super spacious giving lots of options during the build.

My Vorti setup:

Turnigy SK3 3536 1400kv with 8×6 Graupner prop
60A YEP ESC
Matek F405 Wing
M8N GPS
Crossfire Nano RX
RunCam Eagle
GoPro Session/ Hero 7
Multistar 5200mah 4S

How does it fly? If I could use one description it would be “flying bus”. It is a large wing and gives very stable flying performance. Wind does very little to the overall stability so it’s perfect wing for unpredictable flying conditions.
I flew Vorti in 30mph gusts and I noticed that I was being pushed off the course but there was no additional shakes etc often visible on smaller wings during windy weather.
Due to it’s size and lack my neat wing building skills it turned out on a heavy side. 5200mah 4S packs gives me rather modest flight times of around 10-15 minutes but it’s by no means a slow cruise. Vorti can do around 160km/h easy but large motor consumes amps easily because it’s not a light aircraft. Mine including battery weights around 1.6kg.

Who is Vorti best for?
Vorti is without a doubt best suitable for more experienced pilots who like to have very stable aircraft that can go fast.

Below few flight videos from Vorti:



 

Firefly


This is a different style of wing to Vorti. It has 1000mm wing span (same as Mini Drak) but battery bay is big enough to accommodate Multistar/Turnigy 5200mah 4S LiPo which is great bonus.
It is a very versatile wing suitable for general flying as well as long range adventures.

My Firefly setup:
SunnySky 2216 1400kv with 8×6
YEP 40A ESC
Matek F405 Wing
Crossfire Nano RX
Partom 1.2Ghz / TBS Unify VTX (I switched between the two)
RunCam Eagle 2
Turnigy TGY9018 Servos
Multistar 4S 5200mah

How does it fly? Firefly flying performance depends on the motor choice but the one I chosen for this wing gave me very fast performance while maintaining good efficiency throughout. I clocked 165km/h with this wing so far. Average amperage was lower than Vorti so I was getting slightly better flight times on the same battery (5200mah 4S), purely because Firefly is simply smaller.
Firefly is very stable in the air – very similar to Mini Drak although it is not as agile as MD because of a different wing style.

Who’s Firefly best for?
Firefly in my opinion is a very versatile wing, suitable for beginners as well as advanced pilots.

Vortini

Here comes the recent addition to the E-Wings family -> Vortini. It’s Vorti little brother or child if you wish 🙂 Scaled down version of the mighty Vorti. Ewan asked me if I could do some test flying / beta testing this little bird so I was actually flying Vortini No. 00001 weeks before it was actually released! Lucky guy am I? 🙂
Anyways, Vortini is approximately 690mm small wing that can be build to meet 250g weight restriction (proven by GizFPV).

It has pretty generous battery bay but components compartment i rather small so bet suited for tiny bits like Matek F411. Please bear in mind that I didn’t get the final revision of Vortini, so my flying experience is purely based on the prototype kit I was flying.

My Vortini was not built with weight saving in mind so I ended up with rather heavy aircraft. I have started this build to be run on 2S and F20 T-MOtor with 4″ prop but it didnt even lift so after testing 3-4 different motors and props I settled with 3S batteries and F80 motor + 7″ prop. That gave me plenty of speed (120km/h tops) and pretty good efficiency (cruising at 4A and 50-60km/h). My aircraft has RunCam Split 2S fitted at the front as a second camera just for HD so I am still able to get HD footage of decent quality.

My Vortini setup:
T-Motor F80 1900kv + APC 7×5
LittleBee 35A Blheli_32
Matek F411 Wing
Crossfire Nano RX
TBS Unify Pro SE
Emax ES9051 4.1g Digital Servo
RunCam Phoenix „Oscar Liang” FPV camera
RunCam Split 2S HD Camera
3S 1550-2200mah

How does it fly? Vortini has the smallest wingspan out of all wings I talked about and as a result it doesn’t fly as stable as the bigger siblings but….with really calm weather it is possible to get this bird on rails. Overall I find Vortini stability in the air to be even better than popular AR Wing which is 900mm!
It doesn’t take much effort at all to launch it which is huge bonus. You can fly that thing for a long distance as well as do close proximity fast flying.
One note worth mentioning – Centre of Gravity (COG) location has big impact on performance. It should be around 1-1.5cm from the wing front edge. If it’s shifted to the back Vortini will show “pitch jumping” which is super annoying.

Who’s Vortini best for?
This is easy question – for pretty much everyone. It’s great for long range pilots as well as occasional close proximity wing fliers. Depending on the setup it can be super lightweight as well as more powerful with big prop – all depends.

Summary

I wrote about Ewan’s wings in the same order I got the build. Vortini is one of it’s kind with fantastic stability. Firefly can be easily treated as Mini Drak alternative for those who need cheaper wing but offering similar performance. Vortini, as the smallest here offers a lot in a small form. In my opinion E-Wings aircrafts offer wide variety of flight performance and everyone can find one that would suit the most.

(I can tell you a secret: my favourite one is Vortini 🙂 )
