You have used the Ticks option twice.

I'm not using that in the last snippet

Does Manipulate[If[t > Tmax[v0, theta], t = Tmax[v0, theta]]; Show[Trajectory[t, v0, theta Pi/180], PlotRange -> {{-2, 2}, {-2, 2}, {-1, 1}}, SphericalRegion -> True], {{t, 150, Style["Time", 10]}, 0, Tmax[v0, theta], 0.1}, {{v0, 0.25, "Velocity"}, 0, 1, 0.01}, {{theta, 63.3, "Polar angle"}, 30, 150, 0.1}, ControlPlacement -> Bottom] work for you?

It works as of version 8.

Could you try adding the option "ExtrapolationHandler" -> {Indeterminate &, "WarningMessage" -> False} to NDSolve? (if you have a reasonably recent version of Mathematica)

comment How to prevent extrapolation in Manipulate?
It doesn't seem like a detail to me. If the stoppingtest doesn't work because it's not an actual option then Tmax will always be 1000.

comment How to prevent extrapolation in Manipulate?
This option is unknown to Mathematica. At least, in my version 10.4 it is colored in red and not present in the documentation. I believe that it might have been there in version 3-5 or so, more than 10 years ago, but currently one would use WhenEvent.

But what about this unknown option Stoppingtest? Why do you have it there?

comment How to prevent extrapolation in Manipulate?
I don't see your problem, actually. Also your Tmax is fixed at 1000 as it simply the upper range of t as defined in the NDSolve. Your StoppingTest is an unknown option. This might be the cause of your problem.

comment Implicit hidden assumptions of Mathematica with Limit
The fact that the limit with a certain assumption yields the same result as the limit without assumptions does not imply that Mathematica makes the same assumption. That's a logical fallacy.

comment Roots of a characteristic equation. Can Mathematica solve it?
What's wrong with FindRoot[Cos[y] - 2 E^(-y)/(1 + E^(-2 y)), {y, 1}]?

comment Data acquisition from TCP socket
As to AppendTo (which is actually a totally unrelated question): Reap/Sow would be one approach. The other would be using something like a={newData, a} (rinse&repeat) and then a Flatten at the end (which is fast).
