Hi the mini thunder is pretty cool... It will flip on it's top if you turn to the right hard and fast.. Also one thing i do not like is it hardly turns left you must go slow as a slug and also when you turn it sometimes gets air under it and cavitated like crazy!! You can probably avoid this but with the esc that comes with it when you try turning it feels crappy like you can go very slow or snap fast no inbetween speeds that's why it cavitates all the time..
But it flys i have everything stock but i poped in a electrifly T-400 motor that they say to use for a hop up.
ENJOY!
