Gyrocopter flew with me to Alma today on my first cross country in my Kolb Mark II Twinstar.

Just curious.... Could he "keep up" or did you have to back off the throttle?

That's looks like a Sparrowhawk, and they normally cruise in the 65-70mph range.

Mike, My climb rate is MUCH faster, but as far as cruising he can keep up or even pass me.  On the way there I was cruising at 65 but on the way back I cruised at 60 to save on gas.

It is a RAF 2000 gyrocopter.

I just flew my 503 powered MKII and I only cruise at about 45 mph on the GPS at 5200 rpm. At 6200 I can get 60 mph but no faster.  Do these numbers sound like what others are seeing?  I have a 3 blade IVO prop.  Average fuel burn looks to be 3 gph.

Malcolm, On the way there my rpm was showing 6000 and I was cruising at 65mph on my ASI (and the GPS registered anywhere from 47 to 65).

On the way back my rpm was around 5700-5800 and I was cruising at 60mph on my ASI.  I have a 66inch wood prop.  At the rate I was going I burned approximately 4 GPH.

Cruise speed for me, was increased ALOT by changing my 3 blade IVO

to a 2 blade ( I bought the "Blocks" from IVO )



 My cruise used to be around 60.... I'm 70 plus now



 The other day I was a little high on the throttle RPM's .... I looked at my Airspeed...  I was doing 80 !!!

Maybe I should try more prop pitch.  My CHTs are 300 but my EGTs peak at 1200 (1100 at full power climb).  I have home made streamlined struts, but no other "speed" mode.  I don't have a VSI, but I will do some timed climbs to see what type of performance I'm getting.  What are you seeing for climb rate?  If I could get the cruise up to 55 that would be huge!

Try increasing your pitch, it does not take long, and you can always put it back if you dont like it.



I decreased the pitch on my 912-s a couple weeks ago to get full RPM on takeoff and climb out....   It got me a couple more hundred FPM in climb, but cruise sucked, I had to run a bunch more power just to get the same cruise I did before.  I put the pitch back for 5200 RPM on climb out, it restored my cruise speed with lower power settings.

Might be helpful to know the top RPM on climb out.

Nope, don't mess with your carb till you get your prop set up  

correctly. Your top speed indicates that you do not have the optimum  

prop configuration. Unless your prop diameter is less than 66"  

diameter you will do significantly better with two blades than with  

three. What you need is more prop pitch.

 Sounds as though you might be a bit lean on your midrange. You might  

 try to raise your jet needle one notch.

Quick update

I added a half turn more pitch to the 3 blade IVO and my 5200 RPM cruise went from 45 to 50 MPH.  My top speed went from 60 to 65 MPH.  Climb still good (not sure of the rate).  EGTs  quite a bit cooler, but engine running rough in the mid range.  I think it's too rich now.  I will try dropping the needle 1 notch later this week.

Does that RAF have a horizontal stabilizer on it?  If it doesn't  don't fly in it. That particular gyroplane has killed many high time pilots. Its unstable without the H stab on it.

Larry,

I can't ever see what you are writing.  It shows up as blank on the website and I don't get the emails.  Maybe it's the font you are using.  I think I saw Matt Dralle mention that to someone else.

Grant,

Now you're delving into what has been "discussed to death" on threads and threads of gyro forums.  I won't go there.  I just know that I totally trust riding in that gyro and totally trust who is flying it. 



Thanks for the concern.

Cristal

Malcolm,

I don't have a VSI either.  I'll time my climbs next time I go and let you know.  I'm glad you are seeing better performance after adjusting your prop.



Thanks,

Cristal
