RE: Whobbies Team Pro or Magnum 57 or Manta Ray?
I will ask the question nobody else did.
What do you want to do with the boat ?
If you want to play, then either one will do depending on your money.
If you want to play, and then maybe race, then you need to look at a different manufacturer.
Check out Jims RC boat dock for better info if you want to race.
For play, WHH or Bonzi produce nice hulls. I am partial to Bonzi, but their hulls are stronger and heavier than WHH.
