The Vortex 250 Pro is another great ready-to-fly racing drone and it’s a direct competitor to the TBS Vendetta. It’s about the same size, but a bit heavier and comes with two bladed propellers instead of three like the vendetta. Typically, two bladed props will be slightly more efficient, but three bladed props have more power and a crisper flight characteristic to them. You can change the props on both quadcopters if you want to, but then the flight controller will have to be re-tuned.
The main difference between the Vendetta and the Vortex 250 is that you aren’t getting the removable arms or the modular components. With the Vortex, it’s not going to be as easy to fix and you won’t be able to upgrade it to get more power, but I think it’s still a good alternative to the Vendetta and better than the older Vortex 285.
