It came fully assembled and in perfect condition. If you are technically inclined this is the gift for you.
Super happy with my orders, well made and work perfectly. Delivery time is decent and order is allways wrapped real good to ensure it arrives in perfect condition. I highly recommend this store to collectors , educators or hobbyists.
The engines work as advertised, and I'm using mine with solar heat as the energy source.
Very nice kit, high quality parts, works real good and is strong. Packaging was very good everything showed up in perfect condition and in a reasonable time.
