Hi everyone!I just get both 44018 and 44019 from the nearest Toy R us Store and i enjoying play both of this set.I read the instructions books of both 44018 and 44019 and when i saw the combination models provided at the last pages,I have mixed feeling about the combiner model.The idea is great but the execution is bad (Just look at Evo Xl Machine Combiner…why!?)So.i build this combiner machine using parts from Rocka Stealth Machine and Furno Jet Machine.What you think about this combiner machine?Let me know about it.
