I believe that Helipal is an amazing website. I bought a storm racing drone and it was in perfect condition. I had a nasty crash and blew one of the motors, we emailed Helipal and they sent us 4 replacements for free without question. They usually respond on time but it is difficult with the time differences. For all of you people saying that your GPS is broken it is not Helipal's fault, it is the supplier that has made it incorrectly.
