Forged for a King in a distant realm, the legendary Excalibur is here.
The most anticipated Durafly release this year, The Excalibur must be flown to be truly appreciated. Innovative design features, such as the cantilever forward swept wing, V-tail tail surfaces, incredibly strong construction and stunning lines.
Just like the legendary sword, Excaliburs strength is paramount. The engineers at Durafly were given their hardest challenge yet, to design a wing that is ultra thin but incredibly strong in EPO foam!
The wing has carefully positioned carbon fiber reinforcement and pre-tensioned glass fiber strips. The fuselage is feature packed with a square carbon fiber tube and glass fiber strips. The V-tail along with control surfaces are reinforced. All these features combine to make the Excalibur a weapon.
Servos are all pre-installed with a whopping 3542 800kv Aerostar brushless outrunner motor up front. 60amp Aerostar brushless speed controller. Two piece removable wing makes assembly fast with wire-free PCB connection between the wing and fuse.

High landing speed. Stable and precise , no stalling tendencies.. Used 4s 2200 mAh high performance LIPO. Used engine in unlimitied verticals and it flights long time after without engine. Air resistance low giving long flight time Air intake below the engine picked up the soil when landed on wet surface. In next flight i put tape over lower vent without high heat when using motor intermittent during flying. I used some degree of flaperon during landing giving more break and lower landing speed. Ailerons was much more insensitive but no stall tendencies. Exponential set to -60% on all rudders gives good controlllabilityLo primero que me sorprendió de este avión en sus primeros vuelos, es como silba y lo bien que vuela, le gusta ir rápido. Tuve que repasar el sistema de cierre de la cabina para que cierre bien pero en general se aprecia una fabricación de calidad.
Opté por utilizar 4S de grafeno, siendo todo un acierto, las trepadas en la vertical son interminables y la batería baja ligeramente templada.Great warm liner well impressed with this great glider 1800 4s flys like it's on rails great high speed low passesi'm running this with the 13x8 prop from the start, and it has unlimited vertical. it's a very stable plane to fly, and very fast in a dive. once you start to go horizontal after a dive the speed bleeds off, due to the plane being foam. as as i can tell this plane has no bad habits at all, you just need to program the ailerons separately so you can put them in spoiler for landings.
the only problem i had with the plane was the Y-cable provided with it wasn't working, good thing i didn't actually use it! also it rattles a bit from a tiny bit of play in the square spars, not that big of a problem but you can hear it in the air when flying with high winds and going crosswind.
overall a great step up to hotliners and diving fun! with the 60C 2200 4S lots of flight time too. i bring this plane everytime i go flying, it just doesn't care if there is a minor storm going on, it just slices the air with ease!I suspect this is essentially an improved version of Durafly's Dynamic-S. The designs are so similar that I think they just reviewed the old design, found the flaws, and tried to put the fixes into this plane. It has more power, better reinforcement in the wings, a bottom plate on the v-tail to improve the mounting, decals that are pre-installed, and and a few other improvements.
There are also some other changes (such as a slightly forward-swept wing design) that I am not sure if they actually improve anything.
Assembly is very fast and I didn't run into any issues other than a small problem with the canopy I will describe below. Everything fit together perfectly. After it was assembled, it looked great.
The Excalibur has many positive features, but it also has some flaws. The vents on the side of the fuselage are a structural weak point. RC Groups forums recommends putting carbon strips above and below them. I didn't do so and it cracked there when I crashed. RC groups mentioned a flaw with firewall on early versions of the Excalibur, but I did not have that problem... maybe I bought it after they fixed it. I did have a problem with the canopy's latch mechanism. One plastic piece in the fuselage was poorly molded and had some extra plastic hanging down on the bottom of it. I could use the latch, but I had to be careful or I would strip out the plastic latch in the canopy. To fix the problem, I had to cut the plastic latch point out of the fuselage. Then I cut off extra plastic and glue it back in place. It wasn't hard to do and there is not any visible indication I did so on the fuselage. However, for the price, I expected better quality control.
The plane flies great. The speed is good--it is not as fast as some other models out there, but it is still faster than many other planes. The manual recommends a 4s lipo, but it also flies fine a 3s. You won't get unlimited vertical on a 3s, but it won't have any problems doing steep climbs. I use a Spektrum radio and I did have to tweak the default v-tail mixes a bit because the default settings left me with very little rudder authority.
It flies very well, but keep in mind that this is not a beginner plane. It does not handle crashes well at all. The reinforcements keep things stiff, but also rip the plane up on a hard crash.
Overall, it is a good plane and I am happy with it. I was hesitant to spend the money on it, but I am happy I bought it.All I can say is.....Wow
Easy to put together. Although the tail can be a bit of a fiddle to get the servo cables tucked in. I took the advice and glued the v-tail in for security......and having now flown it within an inch of MY life, I can say it probably doesn't need it. All the stress is through the massively strengthened wings.
On that subject. I have never seen a plane with as much reinforcement throughout its entirety. Fuselage has carbon runners either side of lower joint.
The wings have multiple braces at different points throughout the span and chord. The elevator and ailerons are also notable for their inclusion of a full length carbon rod.
3S batteries (30c Turnigy) are too light making it tail heavy, and a real handful in downwind conditions (20 knot winds).
Vice versa, it climbs far too much into wind.
4S Graphenes are a dead size fit at 2200mah size. 1800's leave a bit more room (Not much!) to get cables tucked under beautiful strap.
Be careful about position of balance cable as it is VERY close to the back of motor.
It flies superbly, going from a virtual crawl to ballistic vertical in seconds.
Point it at the stars and watch it disappear VERY quickly.
Then, power off, let it nose dive vertically and pull out at head height and have it tear past you sounding more like an edf than an unpowered glider. That noise is addictive........
It DOES tip stall if you are not careful flying into wind off power, and quite violently. Hence apply power straight away or you have a 'moment like I did. Virtually unflyable and almost tears and early bed.
Buy one. I'm going to.
That is....ANOTHER one
I'm going to set one up purely for windy slope soaring (plenty of wind here on the west coast of Scotland), and the other for power at the club runway.
Love it. Love it. Love itLove this thing. Easy assembly and set up and a versatile flier. Flies well on 3c and very fast with 4c. Put each aileron on a separate channel instead of the provided y connector which allows for differential throw and mixing a spoileron function to slow down for landing. Has a nice fast flat glide power off. And fully aerobatic.Have owned this plane for about six months now and is my go to plane when going to the field, my only knock on it is the plastic fire wall/ nose cone continually brakes, on to the third one now. Don't know why mostly on 3s, only a few 4s packs through it, myself I think it is the prop brake is to violent a stop for it and it just brakes the plastic nose cone /fire wall.Would be better if it had fibre reinforcement. Even though all this still love it, flys in any weather and is the reason I bought another one as a spare.Came in good shape, easy to setup. First flight was a blast, and it did turn heads i can tell you. Was warned about tip stall with the forward swept wings, but seemed not to be an issue. Only beef is that after just one flight, the screws that hold the wings to the fuselage were pulling through the rather flimsy plastic, and one wing was about the come off. With the spar, it probably would not have come off but would have rotated around, and caused a crash. It is easy to fix using for example, good strong hinge tape at the wing/fuse junction.Brilliant plane but it should come with the upgrade prop as stock tbh. I had the walrus a while ago and this is like that, but on steroids and crack at the same time. I had a 2.2 smah 4s 60c zippy lying around that I threw in and I get unlimited vertical with it and around 10 minutes on climbing, shutting throttle and enjoying the satisfying whistle as it scoots by at silly speeds on the glide. Off throttle this thing is just amazing, it glides FOREVER and will test your landing skills becuase it doesnt slow down (find a large field to land it). Stall is a non-event and I would say it carves as good or better than my efxtra (which is AMAZING too). Love this plane, may buy another as a spare its that good, but I will get the upgrade prop to get just a little more oomph out of it.
