We cruise around 120kts with the pod. We also have the bonair conversion, means you can run at 300hp all day. Runs closer to 130kts.
T28D, what were you carrying in your pod? Balls of lead?
Its only a small pod and max weight is 100kgs. The C of G change is tiny when stuff moves in there, if it can move at all. Mind you, I'm used to carrying bags that you have to "persuade" into the pod.
Pods are also great for bringing the C of G forward. You have 6 people in that plane, plus baggage, you will end up with the tail on the ground.
