The dimensions of G-Rep are 48 inches in width and 42 inches in length. You’ll likely need additional clearance on one side for accessing your seat. If you can access it from the front however, you may be able to get into your seat without needing additional space.

G-Rep was designed to work with some VR headsets. As of now, we can confirm that HP’s Reverb2 and Samsungs Odyssey + is compatible. We expect other like type headsets will work also that have head straps like the Reverb2 where a single strap go’s over the middle of your head from front to back. However, while G-Rep’s headgear has cutouts that allow the use of the built in speakers on the Reverb2 and Odyssey +, other headsets built in speakers may not have enough clearance.

G-Rep’s headgear was carefully designed to be adjustable in every way in order to fit your head perfectly and comfortably. This is especially important when using VR headsets since good fitting headgear is essential in keeping them stable so they keep in the “sweet spot”.

Yes, some assembly is required.  Due to its size, it would be very expensive to ship G-Rep in one piece.  Therefore, your G-Rep will arrive in two separate boxes.  This allows us to ship it as inexpensively as possible and also keep assembly as light as possible.

We used a reclinable “universal” racing seat when we engineered G-Rep.  However, universal seats are not all the same.  There is an example below of the seat we use and we recommend a seat of similar style.  Most important is when seated, the top of your head is not more than 2″ above the top of the headrest or G-Rep becomes less stable since it has to be positioned higher on the seat.  Ideally, the top of your head will fall below the top of the headrest by 2″ to 3″ (see image below). Also, the ability to recline your seat slightly will probably be necessary in order to allow more room for your head to move backwards for acceleration replication.  Included is a memory foam support that is used behind your back to reposition your body forwards again to is usual position.

You will need to provide a standard fan that uses either 12 or 24 vdc.  Brushless fans are not supported.  Nautical bilge blowers are often used since they usually output a good amount of air.  You will also need a motor controller and a power supply of your fans voltage to operate your fan.

We include four straps with locking clasps that you use to secure G-Rep onto your racing seat.  G-Rep uses a “riser assembly” that is placed on the front of your seat but behind your back, that consists of two pieces of 1/2 square steel tubing that run vertically along the right and left sides of your shoulders and upper back.  A strap is then wrapped around each side of the riser and then wrapped around the backside of your seat where it is cinched down tightly.  Generally speaking, one strap goes behind your head and around the back of your headrest.  A second strap attaches at the bottom of the riser and wraps around the back.  And usually only one more strap is needed in the middle that wraps around behind the seat belt cut outs. However, a fourth strap is included because sometimes it’s not possible to use a single strap between the belt cutouts and you need a strap for each side.

Installation of our Cranium app is pretty straight forward since we use an installer that takes care of the entire process for you.  When you run Cranium the first time you will be confronted with a flash screen asking you to register it.  It will also show you an Id number for your PC.  Before you can register you need to email us your Id number along with your name and customer order number to activate@g-skull.com. Then, usually within 24 hours but sooner if possible, we will send you a key to register. 

If you move the installation to another computer or drive in the future, you will need to resubmit your Id number etc. and ask for a new key. Your first replacement key request is always granted. Later requests require an explanation why you need one and are evaluated for merit but are usually granted, especially when extended periods of time has passed since your last request.

Often you can use G-Rep with other types of motion simulators since forces are applied on your body differently and usually one doesn’t interfere with the physical operation of the other.  However, motion devices with heave settings that exhibits strong vibrations in particular can be a problem because G-Rep doesn’t have much clearance between the top of your head and its overhead running mechanisms.  Also using heave settings such at that would likely require the use of motion compensation when using VR headsets where G-Rep used on its own does not.
