Summary of change:
Engine is one I am building from drawing board up for an aircraft that I am also building, hence the '''low rpm as it is direct drive'''. * Static ground revs no more than 2700 other wise the propeller tips will break the sound barrier (inefficient) ** guessing: 3000 RPM (=50 rev / sec) = 330 m/sec, circumference = 6.6m. Is the propeller dia ~ 2meter ? * we put as much pitch on prop as to limit revs * also engine internals would not take high rpm (the internal forces go up by the square of the revs]) * legs out of bed in the sky causes one to sweat a bit , thats why we use the fan to keep us cool Prop 1.7m 2500 most efficient rev --- '''Injectors''' are out of a Nissan 280z are 2.6 ohms [ barbed tail, will consider changing ] and best idea of cc rate is 270. * we do not recommend low-Z injectors even on ground. Point noted. Will be changing later as I need to remake injection ring. But first I would like to get it fired up Is there a manual directly relating to 0.10.14 I am finding it impossible to go forward without better information. Basicly the Members page have answers but generally dont say how they got them it is also a pain to wade through such a lot of data and not really gaining much
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
