Hi Andrew,

What's the climbout and vertical performance like with the Wren and how much throttle are you using most of the time? With around 17 pounds of thrust, mine leaps off grass like a scalded cat.

Have you had it start to bounce yet on a landing? It may be that the increased weight of using a bigger engine provokes it more easily, although the suspended spreader-bar has certainly taken care of that on mine.
