TFL Pursuit

Dear Sir or Lady!
Not so far ago I bought a TFL Pursuit Racing Boat at your European Warehouse! But after two Runs with this boat, the Motor sends endless only two short Beeps, but it doesn't work! I've been driven it with a 90A ESC and a 6S Lipo Battery, and I thing, these are the wrong components for this boat, aren't it?
So I hope you can give me some Tips for the wright Components, especially for the ESC and the Battery, because I like this boat very much!
But perhaps give me also a Tip for a powerful and healthy brushless Motor, if it, (I don't hope so), get collapsed and suffers a "Not-to-repair" Malfunction!
Best Wishes and kind regards from Germany!
