ok so say i bought this airplane http://www2.towerhobbies.com/cgi-bin...?&I=LXGFK0&P=7 the battery it comes with is 900mAH. So if i bought a battery of the same voltage but it had higher mAH the airplane would run for longer? i had thought this was a good idea until i realized that if you have a higher mAH you also have a higher charge time right?? so basically im asking if it is a good idea to put bigger batteries of the same voltage into that given airplane as well as asking if i did there wouldnt be much of a point becuase i would still have to charge the bigger battery longer right??

Thanks
