BG155636189 I believe it's 9 amp...I use the astrolux 15amp 21700 and it's got plenty to get max power.

BG155636189 For throwers if there's any fog, rain, snow etc in the air the 5000k cuts through better. Less reflection back (glare) from particles in the air. On a clear night the higher k will outperform lower k.

BG155636189 Yes one car and one controller. These single cars are better than the ones in the two car deal however.

BG155636189 Yes it is dual action. The description doesn't mention it. I believe the extension piece is why....it keeps the valve from being held open.

BG155636189 Rear wheel drive, no doubt about it.

BG155636189 You can bind as many cars as you want to one controller. You can also switch them from one controller to another. Binding is very easy and quick to do yourself and clear instructions are provided.

BG155636189 Sure if you want to get it bound with fibres and hairs. I would avoid all carpets.

BG155636189 The speed is proportional to it's size. You don't run this on a gym floor or your kitchen floor. You make a track, and when run on a track it's very challenging to go top speed on a tight course.
