Depends on how much the retracts weigh. I'm good about building to a maximum weight. I normally beat the weight by 10-20%. I start my designs by choosing a size, powerplant and wing loading and do whatever it takes to stay below that.

I can't imagine building a wing that would weigh 11 lbs. I'm not sure what the engine weighs but I think it's a little over 3 lbs.

I'm thinking a 3-blade carbon prop so I can keep the gear as short as possible. Maybe twin pipes on the engine.
