hi,
i have just put together the H9 B-25 and will be starting the hellcat very soon. the B-25 is well made and from what i can see does not need much re-enforcing at all and same goes for the hellcat. and from what i have heard they both are great flying models.
but as with ALMOST ALL ARF's check them over well, they are made by several different people and not everyone does the same quality work. if they did we wouldnt need a warranty
