I watched the first four episodes yesterday, and it is definitely for a much younger audience... even to the point of making sure the rollcall of names is repeated several times early on.
The character of Hotshot is annoying, constantly acting like an arrogant brat, which will appeal to kids who behave like that... but doesn't focus on him learning to be a better, more responsible person, so that the kids watching learn or be inspired by the benefits of being a responsible, reliable team-member. A flaw of the shorter 11 minute episode format, which doesn't allow for a proper 3rd act to plausibly resolve the situation and focus on the lesson being learnt.
It might take a few more episodes to get a feel for it.
Is it worth starting a review topic, or just have the couple of us watching this cartoon to just post occasional comments here, if anything significant occurs.
Channel 11 (Toasted TV) played all four seasons (with parts cut out), but I don't think channel 99 (nineGo) have screened past season 2, as every time I check in on their screenings, I haven't seen any from season 3 or 4.
