With the recommended throttle and pitch curves set as per manual, I explored the basic 3D performance of my T-Rex 250. Transition from normal flight-mode to stunt one flight-mode was very smooth. Loops and rolls are very gentle, and executed without unexpected surprises when inverted. For a faster 3D response, I tried some loops and rolls in the stunt two-flight mode. The T-Rex 250 is very nippy in the stunt two-flight mode, and I think that any 3D maneuvers are possible in this mode due to the high main rotor head speed.

There was no drop in main rotor head speed, no matter how hard positive or negative pitch was applied. Overall I found the T-Rex 250 very responsive in stunt one and two mode, and I’m sure that anyone will enjoy this little helicopter when flying basic 3D maneuvers.
