If This is in New Zealand I doubt very Much It could be legally run in a built up area (suburbia ) and even in a rural area the noise would be prohibitive.
Speaking from the experience of owning an American Dyna Jet in my youth, the noise from even a small single Ramjet is horrendous to say the least. They are available to buy from several sources for tethered flying (control Line ) and am not sure if Radio control is allowed as they are difficult to throttle, unlike a jet turbine which also is a lot less noisy.
I remember that when the jet stopped the echo of the noise it made resounded from the hills in the valley I live in.
A really reliable way to burst your ear drums and loose friendship with your neighbors and the noise police !
Starting on petrol involves a Model T Ford trembler coil and a spark plug. fuel injected from a tyre pump pressurising the tank initially, then spray bar once alight. ignition is automatic once running.
