that prop is way to big, run your 2w25 on a 4s with a 5.5.x4.5 setup,2200 mah packs may be too little,your runtimes will be short and your packs will not last very long, i was pulling 50amps with this setup and getting about 120mph,you can pik up some 2s3300mah packs from hobbycity and run them in series and you be light and fast.everyone who tries to go with a super light setup on there funjet ends up swapping it out for sumthin faster,do it right the first time
