Sounds good, noob

. You're getting all kitted out.
The Gazaur and Mini Titan are completely different, for sure. With the 340 mm blades (or the 350 mm on mine) the Gaz is very responsive and keeps up with the MT in most things with similar power systems. My MiniT has a 4S setup with a Scorpion HK-2221-12 and 3153MG servos, though, so it's more powerful and responsive and a whole lot more precise (none of the vagueness the Gazaur has).
To be wholly honest, I'm thinking of retiring the Gazaur. It's wonderful to fly aerobatics with, and there's nothing anywhere near as pretty, but frankly I'm getting tired of dealing with the shortcomings. It stinks because I have probably a whole second Poseidon in parts, but I don't really trust it in hard flying any more. It was a beautiful design, but some of the manufacturing choices stank.
