I have to agree with what everyone else has said about nerves and all of that. I'm presently building a trainer from plans so I haven't gotten into three dimensions yet but, that being said, I do have the same issue in 2D. I am required to take a driver's test to be qualified to compete at races held by the scale hydroplane club I belong to. Last time I tried to take the driving part of the exam, someone else launched a boat in front of me resulting in me taking my eyes off my boat. Net result was the boat took some serious damage due to me looking away, nerves and adrenalin overload. I'm now scheduled to try again on Saturday, running 5 laps around a marked course in under 2 minutes driving a boat that tops out at around 70 MPH. Looks like another round of adrenalin overload
