Have the Amewi Firestorm ordered for my son, as Eratz for a casualty Silverlit Atlas. A great success! The Amewi can be much more precise maneuvering and flying much more stable than the Silverlit, which could be hardly correct trim.
The only downside (hence only 4 stars): As with other reviewers came off one of the counterweights and had to be attached with superglue again.
All in all, s great toy with a high fun factor, even if the processing could be a bit better.
