udi - the wild hare is a marvelous plane but!!!! you want it as light as possible - so the zdz or da is the way to go - i have a da50 in a chip double vision and its a great combo - from what i read the zdz is also in the same leage - further more the da is a read valve engine so it makes for easy starting and good transition the zdz is rotary valve which makes for more complex starting but awesome throttle response - for me it will be the price only!!!
