1 Shock Cone can easily support 4 Rapier engines and there is no benefit in extra air intakes . What you ' ll tend to experience before flameout due to a lack of intake air , is flameout due to speed , all engines have a flameout speed when the air is moving too fast for the engine to be able to generate thrust . Rapiers tend to flameout at 1625 ms , depending on the weight and draginess of the plane you might not be able to attain that speed , but the average spaceplane can easily reach 1500 ms on airbreathing rapiers . <| sep |> This Truglo TruTec is $ 90 . 39 tax where applicable with the code GMA 30 .
