HAHAHAHAHA.....I am into my third year. And also on my third plane. And with each new model I get the shakes. I reckon they will always be there since I build my own and as my stepson says....no way he could ever try to fly one he had so much time into while building it. Way to scary. I imagine its just as scary to fly a brand new ARF. The message here is the shakes go away as you gain confidence, but may come back as you add to your fleet.
And I have never used a neck strap/tray simply cause Ihave never thought to buy one. Not opposed to either idea.
