Guys
The "spike" as you call it ONLY functions in supersonic flight and as such has no relevance in the realms we operate our models. I wont go into the aerodynamics, just leave your intake unobstructed.

Well he is making a scale model that has intake spikes. Everyone know that it's not for supersonic flight ! He just want clean air. Hell he could leave the wings off but it wouldn't look right.
