Yes, I can move the stick quite a bit back and forth and the servo will not move. It's just not as precise as the more expensive servos.
But, it's all down the drain anyway. None of the 3 helicopters will see air today. Where I fly, there is a swarm of wasps that have decided to make a home within my eve. And not the ones that usually leave you alone, these are the dark red ones that get pissed off just seeing you. Add noise, vibration and smoke to that mix and they go into defensive mode. I'm not risking myself or any of the helicopters for them. Wish there was an easy way to get rid of them, but I have tried the sprays, I have tried sealing off their hole, they always find another way in. After a decade of fighting them, I give up, they win.
