Hi. This is my first time responding, so bear with me!! Regarding the max wind for the Tello, i dont fly in anything stronger than 18 km/h (11mph). When i tested out the max ranges, i had gusts of 18 km/h and it almost came to a standstill when fighting those gusts. Its so much fun to fly this little bugger, but i would advise to keep an eye on your battery level when the wind picks up so you have enough juice to get home. Also. When i find that im having a hard time fighting the wind, i always lower my altitude since the wind speed is slower the closer you get to ground level. Hope this helped, and keep flying!!!!
