How long has the fuel been in the tank? If only a day or so I would finish running that tank. If it has been longer I would dump the fuel and start using the new stuff. Are you changing the percentage of nitro? Or are you just switching brands? Either way you might find your self having to adjust the needles. It might not be a bad idea to reset the needles to the factory setting and retune the engine.

more than a day and the new fuel is 25% nitro and the new one is 20% nitro i will adjust the needles but shld i clean the tank out with water so its clean or just leave it

I don't see any real need to actually wash the tank out. You should be fine.

It shouldn't matter if there's some residue of the old fuel in your tank. But if you do want to clean the tank out, try flushing it with a little bit of the new fuel instead of water! The engine and water don't play well with each other...

No problem with changing fuels. Either run out, or just dump the old fuel. Anytime you change the nitro percentage, you need to do a partial breakin on the engine since it will be running at a different temp. 3 or 4 tanks without going WOT, then start tuning it for performance.
