The standard Phantom is represented by a car with a H.P. curve which is a little below the average however. Graphs 1V. and V.{VIENNA} We consider that the brakes on 10-EX are very good average. Phantom brakes. Those on 98-NK ( the car previously tested) were rather too efficient, the steering was liable to take charge. Graph V.{VIENNA} once again emphasises the selective application which can be obtainable with the R-R servo motor and the consistent results consequently obtained.
