Learn Spanish (Latin America): Con tener un buen flujo, la cometa pierde el ángulo por la ráfaga. - Despite having a good flow, the kite loses the angle due to the gust.

The structure con followed by an infinitive is a concessive phrase. It is used to express an obstacle or condition that doesn't prevent the main action from happening. In English, this translates naturally to 'despite [doing something]' or 'even with'. Here, con tener means 'despite having'.

Could I just use aunque to say 'despite' in this sentence?

Yes, you could say aunque tiene un buen flujo. Using con + infinitive is simply a more concise alternative. It is especially common when the subject is the same in both parts of the sentence (in this case, la cometa is the subject of both having the flow and losing the angle).

Wait, isn't cometa a masculine word like planeta?

It depends on the meaning! El cometa (masculine) means 'the comet' in space. However, la cometa (feminine), as used in this sentence, means 'the kite' that you fly in the wind.

Why is por used for 'due to' instead of something like a causa de?

While you absolutely could say a causa de la ráfaga, using por is the most natural and direct way to express the cause or reason for an action in Spanish. It perfectly captures 'due to' or 'because of' in this context without sounding overly formal.
