Brake lowers throttle and activates airbrakes in the 2nd photo(airbrakes can lower the rear end and raises the front). VTOL is the initial throttle allowing forward and reverse. You can lift and lower it along with taking of the hinges although this weakens the suspension and cause critical failure. Its two wheel front steering is controlled by roll and also allows a high turn rate along with high rollover risk. This has independant engine to wheel allowing huge acceleration. Top speed so far is 448 mph on wheels(smaller the wheels the faster the acceleration althought the default have a good balance). Please comment if there is a problem and I will try to resolve it ASAP
