This is our 2nd Hosim X08/X07 and it is a great hobby grade RC car/truck. We've ownee several Hosim RC cars and this by far is one of their best. Lots of metal parts (gears, drive shafts, axels). This thing is FAST but easy to control with the pistol grip controller. I love the fact that Hosim has lots of available replacement parts on Amazon and their website. This truck came with 2 body shells and includes a wheelie bar. Comes with a few spare parts included (hub wrench, screwdriver, wheel nuts, axel pins, etc.. & a parts bag) The two 2600 batteries can be paired together but it did not come with the dual battery connector, I'll look for this accessory on hosim's site. I know they have this for their 91xx series cars so maybe the same connector works on the XSeries or is just not available for purchase yet. Looks like they do offer an optional 5200 replacement battery. The 2600 Batteries charge quick and last a good 20-25 minutes of near non-stop run time. This car so far appears to be very durable. Can't say enough good things about this car. It is one of their more expensive models but appears to be well worth the price and at a fraction of what Traxxas cost at hobby shops. These RC cars are pretty tough and will take lots of bumps and jumps, hours of fun and easy to work on if needed. Highly recommend the X Series from Hosim!
