I did do the mod! But you will need a bec to drop the voltage on a 2s lipo I also fitted an on off push button switch with lipo low voltage cut put built in if I remember, you will need to open out the front of the battery tray plastic in the fron of the base to fit it all in, honestly if I were to do it again I wouldn't bother just get rechargeable aa or get a fly sky gt3c it has a lipo pre fitted.
