Are you trying to set max
speed cruise at some low rpm like 5000?
Not at 5000. I've already turned it at 5600, and that
was without wheel pants. Clark designed it for an rpm of 6300, so I'm not that
far off. The general idea was to optimize for cruise at the expense of
take-off and climb. Of course I plan to get it cut back, but I want to get
some better numbers with the pants on before sending it back. I'm thinking of
getting a 2 blade backup prop based on these numbers before sending the 3 blade
back so I wont be grounded for 4-6
weeks.
I think you can work it
out so it won't be that long without the prop. Mine took about a month,
but I didn't try to time it to his availability, and it's also winter, and
he can only do the painting when it's warm enough. I'd bet you could get
this to a two week turn around if
necessary.
If I were you, I'd
seriously consider sending the prop back now, and having him cut it back
some, without doing the final finish. This will be extra charge, but your
static rpm is just too low, assuming the engine is healthy.
I would also do a compression check, because I can't
imagine Lynn being wrong too many times.
Good luck,
Rusty (no engine run
today, but it's
ready)
