The Magnum 46 XLS and Thunder Tiger 46 Pro are the better two and very comparable to each other in power BUT the Magnum has far better customer service through Hobby People Thunder Tiger is through Ace and there service is horrible and there has been many cases where a Magnum engine is out of warranty and it gets repaired or replaced free of charge, There was one case I am aware of the engine was damaged in a crash so it was sent in and with a letter saying how it was damaged and charges for the repair where expected, A week later he received a package with a brand new engine with no charge. I would go with the Magnum.
