Tutoriels Drone

Après avoir décidé de me lancer dans les drones DIY (Do it yourself), j’ai rapidement réalisé qu’Internet débordait d’information, mais qu’il fallait un effort significatif pour trouver ce qui m’intéressait. J’ai donc compilé l’ensemble des infos dans une série de tutoriels. L’object est de proposer une succession d’étapes simples, expliquées le plus clairement possible, et accompagnées des liens vers les sites qui m’ont aidé à comprendre.
Le premier tutoriel est désormais en ligne et porte sur le choix d’un contrôler de vol pour un drone: http://wp.me/P2lVFQ-1qn

A dream comes true

Début octobre, Shaun Palmer, Brian Lopes et Bernat Guardia sont en France: ils viennent au Roc d’Azur avec Intense. Le distributeur Intense France m’appelle 10 jours avant:
« Allo Laurent! Tu peux descendre début octobre dans le sud? J’ai besoin de toi pour un film: on va faire une session avec Shaun, Brian et Bernat et je voudrais que tu te charge des prises de vues aériennes. »
Il m’aura fallut plusieurs jours pour me remettre de cet appel. Difficile de se mobiliser sur d’autres sujets après un tel échange.
Malgré une météo apocalyptique, j’ai donc pu passer 3 jours de folie, avec ces icônes du sport, qui hantaient mes rêves, adorées sur papier glacé, et finalement encore mieux en vrai. Cool guys ! Et en prime, voici la vidéo finale:

Video: Kilian Bron Heads To Uncharted Desert Territory

After a first episode on the highest sand dune of the world and another one on the Chachani volcano at more than 6000 meters (around 20000ft), the third Mission will be absolutely different.

For this third episode, welcome to Namibia – South Africa with Kilian Bron, for a different goal. To get lost in the middle of the Savannah and to ride fantastic spots, as you all remember the famous The Lion King cartoon.

Starting in Namibia’s capital city Windhoeck, we’re hitting the road with my filmmaker/photographer Pierre for a first week in autonomy. Nothing else but a satellite phone to get in touch with us.

Forget about 4g and Instagram! Welcome to the Savannah, surrounded by zebras and warthogs. The first stop of this journey brings us to Spitzkoppe. An unreal spot more than 3.5 hours away from Windhoek. 3h30 of straight road before the sight of these amazing silhouettes, drawn in front of a crazy sunset. This massive granite rock seems so close, while we’re more than 100km away. Looking around us, we’re surrounded by emptiness. As far as the eyes can see, there nothing but clouds and plains, put in music by the noise of the wind.

While it’s a bit frustrating to arrive at night, we have very fond memories of our first Namibian sunset. To such an extent that we never missed any sunrise or sunset during our trip. Well, just this one time while exploring the deepest trails of Namibia in the Arnhem cave.

In the continuity of a fascinating trip, discovering the Spitzkoppe at sunrise was magic. We could compare this area to Moab – USA for its texture and colors to the famous Cervin (Matterhorn) in Europe with which it shares some similarities.

Between pink sky and orange rocks, we distinguish a large part of the spot through an impressive natural arch. No more time to waste. It’s ride time!

There is a thin line between stress and excitation. To be fair, I never rode such steep lines before… I can’t climb most of the lines by foot, that’s impossible!

These rocks are sharper than a cheese grater. And without any emergency services anywhere near me, I can’t make any mistakes.

By contrast, the grip here is crazy and there is an infinite amount of lines. Everywhere and for everybody. On my side, I have to be creative to imagine how and where I could ride the famous Spitzkoppe area.

Step by step, I found lines than I could have never imagined. That’s a real drug and it seems difficult to be reasonable.

I’m under pressure, at this highest point near that rift. It looks like a long steep ridge of hundred meters with two holes on each side. The start is too steep. So steep that I can’t even check the line by foot. The first ten meters will just be crucial.

At the starting point, I’m feeling dizzy and I don’t know how I will be able to jump on my bike and ride. Without a doubt, the most difficult part is to make the first move and clip my pedals… But I have also to control my speed and take care to the trajectories, that’s crazy.

I’m feeling good on my bike on the first meters and I know exactly what the limits of my brakes and tires are. It’s reassuring to be able to control your speed to keep the right way.

For a short instant, my head is somewhere else and I’m trying to enjoy my line. But the width of the ridge decreases as the speed increases. I’m scared but I have no choice to stay focus to finish my ride in one piece.

It was not easy but I did it! I’m taking a few minutes to catch my breath before finding another great and impressive line on the neighbouring summit.

About one minute of pure freeriding for one full day of practice, that’s the deal! I found a new face to shred, just in front of the Spitzkoppe. The landscape is amazing from here… The starting point looks like a huge dome before diving into a long left off-camber with sketchy gaps.

The rules are the same, no crash permitted! First tries are always delicate and some areas are doubtful… That’s frustrating, I don’t know precisely where the limits are because all my usual landmarks are distorted. However, I know exactly where I have to put my tires to the nearest centimetre.

At this key moment, Looking at the bright red sand dunes of Sossusvlei, I’m not sure if we should be spending more time there. Pushing your own limits is a good thing, but you sometimes need to step back, take a break and breath, to be able to return to it later.

It seems difficult sometimes in the heat of the moment but with the benefit of hindsight, that’s just vital.

By all means, the Spitzkoppe earned its number one ranking on my spot lists. It’s above any other places I’ve ridden in the past, for the quality of the ride as well as the surreal landscapes.

We’re now on the way through the Namibian Savannah for the second part of the trip, the Arnhem cave.

As I was looking for even more originality for my Missions, It seemed interesting to discover the African underworld. In the middle of a mountain range, lost in the middle of nowhere, we found the entry of the cave with a local guy. « Boyboy » guided us through this huge cave :4km long, divided into various chambers.

Previously exploited for bats excrements, it’s now abandoned. Wait… what? Yes, Namibians were turning excrements into fertilizer and Were selling it all around the country. Indeed, it was a flourishing industry, and it seems that they may restart it soon.

Let’s enjoy it! What a surprise to discover that we can ride quite everything with a bike, except for extremely narrow parts that are going from one gallery to another one. Some spaces are sometimes so huge, that our lights are not sufficient. So that it’s difficult to analyse the relief in detail.

It’s even trickier when I have to cross these parts on my bike. But what a pleasure! The trail is really technical and is composed of rocks and And what seems to be sandy parts, but in reality, it’s bat excrements, with a putrid smell…But we have to pass over it !

I put a neck tube on to cover my face and avoid this bad smell. It helped me breathe alright. The temperature is rising, and after 4 hours getting deeper in the cave, the heat started to get to me.

We spent hours between each gallery, looking for jumps and atypical spots. « BoyBoy » Who knows every single inch of this place, is probably still wondering why I wanted to ride inside the cave with my bike. But for sure he had fun.

Pierre: « Behind the camera, I tried to ignore those faeces particles. Kilian is sending them everywhere… On my lenses, into my bag, stabilizer engines…my nose…I’m consoled by the knowledge that I never had the opportunity to do that before and you can’t put a price on that (nor sense to it). »

As a nod to my first mission of the season, we’re back in the sand dunes for the ultimate part of the trip.

In some ways the landscape here makes me think of Peru and Cerro Blanco… Just in time to enjoy a new sunrise, we are now sitting at the top of a dune in the middle of Namib’s parc. As far as we can see, for hundreds of kilometres: There is only sand… with an amazing color panel: orange, red, violet…Below, on the floor, the contrast is really emphasised by the arid floor.

Deadvlei is obviously the most atypical spot of the region. Covered with some ossified trees, this landscape seems to be from another world. This zone also hosts the highest sand dune, which is about 325m high.

Under a blazing sun, the ascent is challenging. The sand is much softer than during my previous experience. But it doesn’t matter, I have time eventually…

Several times during this trip, it was good to be reminded that our office was absolutely breathtaking and that we are lucky to be able to discover a lot of different spots, as the main job.

This last section notifies the end of our trip to Namibia. A country full of contrasts and the most surprising place I have ever visited. Time to say goodbye to the last animals on the road before going back home.

Stay tuned, for the next unconventional and disrupted Mission.

Syntace C33i Straight Carbon Wheelset – Review

wheel are low-inertia, straight-pull hubs, a fast-engagement star-ratchet freehub with a steel-reinforced cassette spline, and oversized high-load bearings and axles. C33i Straight Carbon wheels use 28, same-length spokes and are available in Boost or Syntace’s zero-dish EVO6 spacing for 1400 Euro. Weight for the pair in 27.5 (tested) is 1580 grams and Syntace backs the wheelset with a ten-year warranty for manufacturing defects.

Full specifications here.

Features and Construction C33i rims:

Syntace has been on the cutting edge of the wider rim movement, and they have learned a lot about the concept since the inception of their aluminum

MX wheelsets

five years ago. Short rim flanges free the tire to follow the terrain, while providing more support. Bead locking internal profiles that guide tubeless tires through the inflation process and efficient V-profile cross-sections that transfer loads without creating a non-compliant structure are a few gems.

Syntace included those lessons, and then took advantage of the carbon process to add some new features that were not possible or practical for aluminum construction. The rim flanges are double thickness for impact resistance, and, inside the rim, triangular cones are molded into the structure to reinforce the spoke entry points, which are correctly angled and tapered to fit Sapim Q-lock nipples. The new interface, says Syntace, is stronger than the spokes. The carbon used for the rims is engineered to be much more ductile, and thus can survive impacts, reportedly, far beyond those survivable by heavier aluminum rims. Finally, Syntace has reconfigured its hub-flange spacing to eliminate most spoke dish, which means all the spokes are the same length and nearly the same tension – an improvement that eliminated the need for the spoke offset of its original W-series rims. Going forward, all Syntace rims will be drilled symmetrically.

Straight MX hubs: Syntace is especially proud of its latest MX hubset. They incorporate straight-pull spokes, made for Syntace by Sapim. Syntace says that the smaller flange diameters help reduce fatigue and rotating mass. Internally, both the front and rear hubs use thin-wall oversized steel axles (20mm for the front and 17mm for the rear), and special triple-sealed high-load bearings, said to increase load-carrying capacity by 90 percent. Axle widths are Boost 110/148 and Syntace supports both conventional, centered-rim lacing and its EVO6, offset-rim lacing that is used on Liteville frames to maintain near-perfect spoke angles and improve the chain line. Both conventional hub caps and SRAM’s Torque-Cap interfaces are also supported, and rear hubs support SRAM XD or Shimano cassettes.

Both the hub body and the cassette splines are machined from 7075 alloy aluminum. The freehub splines are reinforced using the patented and proven steel insert developed by American Classic. Inside the freehub, Syntace uses a star ratchet similar to DT Swiss, with 45 teeth, dropping the interval between clicks from 10 degrees to 8 degrees. Syntace says that they designed in some noise reduction to mute the ratchet, but it still makes a deceleration whine that is wonderful for some and….. well, I like it.

If you are the hands-on type, Syntace’s MX hubs are easily serviceable with simple tools and they stock parts. To ensure smoothly rolling wheels, the hubs have threaded preload collars that lock with a small Allen screw. If you are familiar with this feature, you can attest to how simple and effective it is to achieve perfectly spinning hubs.

At present, Syntace only offers the C33i wheels in the 27.5 size, but it shouldn’t be a long wait for a 29-inch-wheel version. As mentioned, Syntace has an extensive in-house testing facility, in addition to a cadre of real-life test riders that they employ to vet out any flaws that may require design improvements before going to production. On that subject, Syntace offers a limited, ten-year warranty that covers manufacturing and material defects free for the first three years and at 50% of the MSRP thereafter for the years remaining.

Ride Report Setup:

Our C33i Straight Carbon wheelset was supplied with the

Liteville 301 MK14

we reviewed earlier. Riding was shared between RC and fellow PB rest rider Harold Preston on various all-mountain and DH trails, most of which feature embedded granite rock, many square-edged impacts, and medium-height jumps and drops. Tires were Schwalbe Hans Dampf (rear) and Magic Mary (front) with pressures ranging from 20 to 26 psi and set up tubeless.

Technical performance:

Removing and reinstalling tires requires a firm press with the edge of a shoe to unseat the bead from the C33i rim’s raised locking ridge. The force was not as great as is required to free the bead from an Enve or the new Syncros carbon rims, which can be a tough job. Once the bead has been broken, tires can be removed or installed by hand. Inflation was uneventful using a floor pump and there was no need to remove the valve core to achieve maximum air flow. Throughout testing, which lasted approximately three months, neither of us burped air, cracked a rim or experienced a spoke failure. Spoke tension and rim runout remained consistent.

The faster engagement ratchet mechanism is an improvement from the previous W35 MX aluminum wheels I have been using for a number of years, and the growling sound they make is music to my ears. I had no need to adjust the bearing end-play, but I did anyway to check the feature. Finger pressure to rotate the Allen-clamp collar was all I needed to zero out the bearings and the hubs run so smoothly that I still spin the axles to experience it when I remove a wheel. The front hub was outfitted with oversize Torque Caps to interface with the RockShox fork dropouts. They hung up on the fork and typically required some shuffling to slide the wheel in accurately (no fault of Syntace, this is also an issue with SRAM’s Torque Cap hubs).

Trail impressions:

I rarely break wheels, but co-rider Harold Preston does. Neither of us were able to damage the C33i carbon rims in any way. The wheels are true within a millimeter, and there is no blistering on the tops of the rim flanges where sharp-edge rock strikes often leave their mark.

Ride quality is the talking point of these wheels. They are precise feeling in the turns, most likely due to their lateral stiffness and also for the secure footprint that the 33mm inner-width, low-flange design creates for the tire. Pressing the bike into a corner flares the tire’s tread into the soil without any sensation of rolling or folding at pressures near 20 psi (Schwalbe 2.35″ EVO casings). A number of wheels can make that claim, but few in the all-mountain class can boast the deft, lightweight feel that this 1580-gram wheelset delivers both while maneuvering, and when under power. Syntace has found the nexus point between a stupidly stiff build, and the twangy sound and feel of an overly lightweight build.

Pinkbike’s Take:

bigquotes Syntace states that they would not consider building with carbon unless they could achieve significant weight savings over aluminum at greater strength – and be able to back the product for ten years of service. While some competitors offer lifetime warranties, that’s still a bold claim for an all-mountain wheelset based around carbon rims. So far, the C33i Straight Carbons are measuring up well. It’s not an inexpensive set of hoops, but you’ll be hard-pressed to find a better option for the same money. If you are looking for reliable and lightweight wheels that can survive ten rounds in the long-travel trail bike ring, I think Syntace C33i wheels would be a good bet.RC
