I use an app called cyclemeter and i got another one called Speedometer 55 and when i was testing my brothers ridstars speed (it goes around 50) the cyclemeter said 60 and the speedometer said 42kph? i know it didnt feel like 40 kph but i dont think it was going 60kph. anyone know why this happened? I assumed it would be the same since they are both using the gps from your phone. Anyone have apps that they use that are accurate? (please recommend me to a diff sub reddit since i know this isnt much about e scooters. i just didnt know where to post)

I have had this drone last summer and never got the chance to fly it. I kept it in a case and never flew it until like 2 months ago, along with the props and stuff. When i tried to fly one prop exploded for some reason and i just figured they were old or something. I took another spare prop and put it on. Its been two months since then i flew it in the backyard to see if it would break but it didnt. When i went to the field when i flew it broke again even tho it was one of the ones i changed before. Are these props just old? do i need do ones or is it something like the drone is vibrating and breaking the props. Idk should i soak them in water so they arent brittle is something my friend suggested
