Ok, thank you very much for this information, I will look at it tomorrow, because in France, it is evening... In fact, I must have had 2 problems, the magnetization problem of the compass (I will do a calibration anyway tomorrow to see if it gives me the message) but also and especially this problem of sticks; besides, I don't understand why, I handle them with care, I'm very careful when I put away my RC, it's weird... I see all that tomorrow and I'll let you know. Really thank you, you are all very good advice and very helpful.
