Have you checked with Finn Lassen to see what
weight his bird is? Your turbo accounts for approx 35 lbs but not having
to haul a muffler system probably saves you about 15lbs.
Thanks for the weight Finn. The two big
killers for me are the turbo, and the radiator. I wouldn't be surprised if
the radiator weighs 50 lb full of water and oil, and it has a 10 lb fan hanging
on it. There's also the possibility that the "B" wings are heavier
than the old ones, though I don't see that it could be much. I also
need to call Van's and ask about the gross weight of the "B" version of the
RV-3. With the new wings, they may allow a higher gross, though I doubt
it.
I have to go check the scales again because I still don't
believe this. The scales themselves are accurate when I stand on
them, but the arms that are being used to divide the weight are new, and I've
never used them before. I also think I should have put a piece of
wood on the scale to spread the load of the arm, rather than letting it contact
in one area. I should be able to stand on the platform and
verify that the scale shows half my weight.
Hopefully, your rough engine is as
simple as a fouled plug. Is it rough at all speeds? Ok at idle rough at
higher rpm?
It gets better as the speed increases, but it's
not "spooky smooth" like I described it before. Until I do some
tuning, there is no idle. It won't run below about 2000 rpm, but this
is something that Tracy is sure is a tuning problem. I would like
to start working on tuning the engine this weekend, and I've been whining
as hard as I can to get Tracy to send me the new firmware. He now offers
an option of using his actual engine parameters as a default, instead of
the normal factory default (which is still an option). That would put
me in the ballpark quickly.
Waaaaa can I have my firmware now Tracy
:-)
Always some last minute things to get
fixed. Good Luck
Thanks. I've already ordered another fuel gauge for
next weekend. Sure hope it lasts longer than the 5 minutes I got out of
the last one.
