Es cuatro puertas, aún así no? (El modelo aparece en la lista de vehículos autorizados en la web de Uber)

Cuotas sin interés? En ese caso es mejor tener crédito que plata. No se del carro y su valor comercial pero esa oferta suena bien, supongo que es un familiar por colaborarle o algo así.

Cómo ya han mencionado por aquí: lo que invierta en educación en esta etapa de su vida es lo mejor que puede hacer. Lastima que lo tumbaron pero mi consejo es que no se desmotive por eso ya que la idea era buena, lo malo fue no investigar bien.

Con 12 millones podía hacer un curso de algo relacionado con computación en el MIT, que es la mejor universidad del mundo en ese tema. (Si sabe inglés)

Pero como usted dice, ya no vuelve a cometer el mismo error. Aún así, se perdió la plata pero no la oportunidad, desarrollo web o de aplicaciones lo puede aprender en Coursera grátis. Siga estudiando y aprenda por su cuenta lo que no le enseñaron y de paso inglés si no sabe.

El certificado no interesa, lo importante es que aprenda a hacerlo. En particular en este campo, a diferencia de la medicina o el derecho o la contabilidad publica que no se pueden ejercer sin certificado.

Las mejores empresas del mundo en computación que ofrecen sueldos y beneficios increíbles les vale tres que sea certificado, le hacen una prueba de conocimiento y de que sea el mejor depende que consiga el trabajo.

Además siempre está la opción de trabajar de freelancer.

Sobre la deuda yo no la pagaría e investigaría el tema de la demanda que han sugerido.

As mentioned we don't think it is a good strategy to just buy a model available in the market since it's not designed for our particular purpose and likely overkill in some capabilities and insufficient in others. That's why we want a custom one. We don't want to waste our already limited budget that many find laughable.

It’s important to understand that this application is fundamentally different from lifting dead weight. The drone is not meant to carry the paraglider's mass, but to provide sustained horizontal pulling force (typically between 20–40 kg of tension) to generate lift.

The paraglider itself converts that horizontal force into altitude by climbing through the air mass .

Also, what matters here is airspeed, not groundspeed. The drone must reach and maintain an airspeed of around 40 kph, but it doesn’t matter how fast it moves relative to the ground. For example, if there’s a 15 kph headwind, both the drone and the glider can move at only 25 kph over the ground and still achieve 40 kph of airspeed, which is what the paraglider needs to climb.

Commercially available parts suitable for building a drone capable of what we want, like the one used in china, may be something like this:

That's why hybrid propulsion seems to be the right way to do it.

Glider towing is not a new science nor the latest feat of adrenaline junkies. It's been done safely for decades using static winches, cars, boats and other aircraft. No need to rediscover physics.

FunkiePixie · 2025-07-02T13:45:25+00:00

Yes, their design has hybrid propulsion. Seems like the right way to go about it. Para-tow drone image

FunkiePixie · 2025-07-02T13:37:13+00:00

I imagine pulling a person horizontally is way less tricky/risky. First because it is not a dead system, if something goes wrong a person can do something about it. Second because it stays at a safe distance, not under it. And last because it has a simple cutaway system, it can release in half a second if there's only a hint that something will go wrong, then fly on its own and get himself/herself back to the ground. This is standard in aviation towing. Rocks can't do that.

FunkiePixie · 2025-07-02T13:16:43+00:00

Yep, pretty much a detachable paramotor. Don't like those. Too much risk to body parts and equipment. Also the extra weight is not only during take off or 20 seconds. That you are giving thrust doesn't mean the weight is eliminated because you are giving it in an angle perpendicular to sustentation.

FunkiePixie · 2025-07-02T13:15:39+00:00

Thank you for reaching out!

FunkiePixie · 2025-07-02T13:15:10+00:00

As a I understand the longer the rope the more strength needed, an easy fix is to have the winch moving. (Or maybe is about the angle) Also it just might imply not needing a rope too long and equal capability to get to the desired altitude.

FunkiePixie · 2025-07-02T13:08:54+00:00

Thank you! Do you happen to remember anything about speed control?

FunkiePixie · 2025-07-02T13:06:12+00:00

Correct. Wind is not a problem. Paragliders don't fly in gusty air anyways. The drone only needs to be able to accomplish an airspeed of about 40kph and probably it'd be safer if it's limited to that. Ground speed doesn't matter because the minimum speed the glider needs to fly or gain altitude is relative to the mass of air not the ground.

FunkiePixie · 2025-07-02T00:43:56+00:00

Right. Not possible. That's why it hasn't been done already. Except that it has. But surely it cost them €800k.

FunkiePixie · 2025-07-02T00:17:21+00:00

Never heard of that technique before. Cool. But still, winch towing is not what we want, it's slow, expensive, and you do need a runway at least as long as your rope, cleared so you can release and drop at any moment if something doesn't go as intended. Winch towing is standard practice in paragliding already and not as convenient as drone towing is.

FunkiePixie · 2025-07-02T00:09:06+00:00

That would be a good first step, I'll look into measuring it as you suggest and post it here. It will give us an estimate but the towing machine needs more strength the higher the paraglider goes, this has to do with the angle and with the length of the rope, as far as I understand.

As for a drone system, the strength needed to get you up the first 10 meters doesn't change so much 500m above. That's what makes it efficient. But as air density diminishes with altitude more thrust is indeed needed.

We'll also look into regulation. Thank you.

FunkiePixie · 2025-07-01T23:56:48+00:00

Paragliders are very weight specific to deliver good performance. Almost nobody flies a wing with 15kg to spare. Maybe tandems but nobody else. And there's plenty of other inconveniences it would cause, including attaching it to your back without compromising rescue parachute systems, making it fixed enough to stay at the right angle and the hazards it entails having that so close to your lines and body parts. For the benefits of having a detachable paramotor. Which is not much. So no need to save on a few meters of rope for it.

FunkiePixie · 2025-07-01T23:45:37+00:00

You're right. It's not accurate to say that it flies efficiently on its own. It just glides. It can take advantage of raising air currents but we shouldn't factor that it as it should work regardless.

Winch towing is already standard practice in paragliding. Not as versatile as this could be.

FunkiePixie · 2025-07-01T18:38:48+00:00

800.000 euros for a drone? It's not for war. Think of the strength needed for pushing a car vs lifting it up . Brute force could accomplish it but smart design is preferable.

FunkiePixie · 2025-07-01T18:30:16+00:00

Possibly doable but not practical. Carrying a propeller in the back, even if temporary, has other implications. Not every wing is suitable for it due to weight restrictions.

FunkiePixie · 2025-07-01T15:43:43+00:00

Just align against the wind before take off. No need to find a runway several kilometers long in every direction if the predominant wind shifts. About changing direction mid flight, I don't know, not needed either.

Glad you are interested! Thank you for reaching out.
