"I really enjoyed this build, you can really tell they thought deep on the individual functions. It's very similar to an F-35B aircraft with a lift fan and re-directional nozzle. If you choose to build the normal jet version: just with one flip of a button it can open up the lift fan, spin the blades, lower the flaps and nozzle. Another switch allows it to auto gear up or gear down. That's truly amazing from a lego. Another surprise is that this kit is a 2-in-1 build so you can also do another version of the aircraft: a private jet. I prefer the look of the private jet, although doesn't have that cool function of the Vertical take-off and Landing like the jet race version, it does have spinning engine blades and gear up/down option. I would highly recommend this!"
