Subject: [FlyRotary] Re: Paul's first
flight (was Re: DAR visit?)
At approximately 3:30
P.M. my SQ2000 slipped the surly bounds of Earth....made a couple
circuits around the airport and had an uneventful (yawn) landing.
Congratulations Paul! I was
thinking about you as the winds started to die down around here. I
thought you'd probably go. BTW- I changed the subject line to show
your proper place in the flying world :-)
From 1/4 to
1/2 throttle, engine accelerates smoothly and plenty of power. As soon as I
try to go above 1/2 throttle, the engine begins to bog down. Advancing the
throttle more only made it bog down even
more.
I bet you wish you had tied your
plane down and ran it full throttle on the ground. I'll never
understand why people don't do that. I'm coming over there to put the
boot on your plane until you prove this is fixed
:-)
I tried tying it down, but because the engine is on
the back, all the ropes got tangled up in the prop, and rpm REALLY dropped.
(not really)
I have to work on the power problem
ASAP. I'm thinking it is mixture related.
You could certainly be
correct. I'm assuming you don't have a mixture gauge, but do you
have an O2 sensor for your MicroTech? If so, you can probably also
connect it to a panel gauge, even if you're only hooking it up
temporarily. For a ground test, you can even stick an O2 sensor in
your exhaust pipe, as long as you can make sure and secure it so it doesn't go
in the prop. I will let you use my old Mixture monitor gauge for testing
if you want to.
Yes, I have an oxygen sensor....my MicroTech unit
displays a lot more than I understand, everything from how many milliseconds
the injectors are open to degrees of ignition advancement. I need to get
into the manual and decipher some of the information it is probably telling
me....I know it displays mixture percentage, MAP, water temp, and 18 other
pages of information, and it even does data mapping whatever that is. It
is probably telling me the information I need, I just need to learn how to use
the unit. If I ever learn 1/2 of it's funtions, I will consider myself
blessed.
Remind me what prop you're
using. Is there any chance it's way too big? That might also
cause some problems.
My prop is a 3-bladePerformance wood prop, 64 x
78.
Again, congrats, and welcome to
the ranks of the flying tinkerers :-)
Thanks, Rusty....honored to be amongst
the ranks.
Cheers,
Rusty
