Its Vmax is c.27mph but (I found out later) its obstacle avoidance capability only works up to about 18mph. I’d say that anything over 20mph is going to cause it problems anyway because head or side winds slow it down and once you outrun its range, even briefly, it will just hover and wait, but by the time you notice you might well be a mile down the track. I’d say it’s probably not much good for open trail riding but it would be excellent for slow and technical trials type stuff like rock gardens and logs etc. I bought it for general leisure use, so I’m not too bothered by those limitations
Serious answer; it's something I have suffered from since a similar "episode"; mine was under exertion but came on quicker & worse when the air was cold. Mine was treated as angina with tablets (Ranozaline 375mg x 2 daily) and a further artery cleared of calcium & scented. That has seemed to sort the problem, maybe worth investigating? HTH.
I've had various tests and chest X-Rays and all have come back clear. My arteries etc are all clear and they put my "episode" down to an imbalance of electrolytes. They think I have developed a mild form of asthma but are saying it's not asthma. But they prescribed the inhaler and so far that seems to be doing the trick
