sensors problem

[blakeagl3]

Hello all,

I think my tello is having a sensor problem. Not always but sometimes when i put my hand under it is not going up, it drifts in any direction (front, back, left, right) and sometimes it doesn't even go in that directions it goes down and can touch my hand. And also the hand landing is not always working, even if i put my hand very close to it.
Is there something I can do? or should I take it to warranty.

Thank you

should both sensors have a light? or one is a receiver and one is a sender?

one is a receiver and one is a sender?

Yes.
