Subject: [FlyRotary] Re: RV climb speeds
was Re: warp drive 3-blade prop
I initially attempted to climbout at 91 mph (or
what ever it was that Van say was best rate of climb) - then I found out all
his performance figures were for CS props. I found out by experimenting
that my best rate of climb (at that time) was 120 MPH IAS - which was exactly
what Tracy said he had found.
Hi Ed,
Did you ever revisit the best rate of climb speed after
you put the C drive on? My RV-8 was like every other standard fixed
pitch RV, meaning that it climbed best at about 120 mph. For some
reason, the RV-3 has always climbed better at lower speeds, particularly since
the C drive has been installed. Tracy said he noticed that his
best climb rate was at a lower speed after the C drive as well.
FWIW, I believe my best climb rate is currently in the
80-90 mph range. Once the engine is trustworthy again, I'll do some
final testing on this. I want to find the best speed, as well as perhaps
trying a small amount of flaps in climb. The flaps never helped the
RV-8 climb, but it's worth a try. I'm going to get that 3000 fpm
one way or another :-)
Cheers,
