arrived in 11 days and I've already painted the spinners and have one mounted for tomorrow morning! love flying this airplane!

Clever design. just 2 negatives.

The design works well, but is not foolproof. You WILL break props, but not nearly as often as with other setups.

Two quick points:

1. Make sure the prop is SECURELY attached. if not 100% secure, the prop can pop off when given RPMs. if this happens mid-flight, the prop can be difficult to find.

2. I applied a light coat of bright paint to the propeller tips. This made it SO much easier to find a missing prop.

All in all, I love the design. Just have to watch the prop seating, and make it easier to find when it detaches.
