I flew three of the new C5-3s yesterday. Two in a 1/200th Saturn V and one in a MAV. Both of these models are marginal off the rod on the C6-3 and go really well on Q-jet C12-4s.

All three boosts were very authoritative and with quite a visible flame from the exhaust. Altimeters aboard showed the 1/200 Saturn V actually didn't go quite as high as it does on a C6-3 (when the winds are low for a straight flight) but the MAV did about 70 feet better on the C5-3.

Both models go considerably higher on the C12-4 than they do on C6-3s.

So for heavier models that are marginal on the C6-3, it looks like the C5-3 is indeed "mission accomplished" but for C impulse competitions, the Q-Jet C12 is the hot ticket by a large margin (and even for lighter models).
