@NEV - My prop adjustment does not have a row of lights. Just a BLUE for full course, and a YELLOW for full fine. There is no indication in between. @Bruce Tuncks - I am with you on this. Ok... if I was making a modification the bird that was major, and would change either how it flies, or how one flies it, I could understand. The manuals speaks of the RPM gauge, but it does not speak of where that gauge exists on the dash. If my LAME is able to completely remove the engine and replace it, without much fuss, why in gods name he can't move the RPM to the left is beyond me. Anyways... I have an LOA on the way from Evektor, so my problems will soon be over. :)

Thanks all, I wish they would put a shot of the inside pages - hard to know what it is by just looking at the cover. :( I did think of making my own, but it would be nice if it were need and tidy.
-
Isn’t that just a maintenance logbook though?? What’s the inside look like??
-
Hey all, Looking for opinions on what you use for your AC logbooks. The previous owner of my AC just used separate sheets all floating around. so I am looking for a nice solution that is tidy and gas plenty of room. Do you just use the Daily Flight Record from RAA? Or a nice book etc? Thoughts?
-
Yep! That is possible too! I have written to RAA asking - but as yet, not heard back. This time of year, it's understandable.
-
Yep! My point exactly. The later models actually have the RPM on the left, AND, it's double the size! So somewhere along the way they decided it's a bit more important! My plan is to get it on the left side - come hell or high water. It was a real PITA yesterday trying to set that prop for cruise, and having to lean over to see it. With a PAX, it would be worse!
-
Thanks Skippy. My dash is all one piece - sadly. My buddy did the same with his. Angled the half that he needed to. Works a treat.
-
Hey Nev, Bit of an update for you mate. Managed to play yesterday and I had to back off at 115, as it was too lumpy! LOL! I still had more throttle and pitch to go, so it really can boogie! That said, it will take some getting use to trying to spot the RPM from the other side of the dash. Pain the backside! I have a request in with RAA to see if I can get it relocated. But happy with how she went yesterday. Cheers John

UPDATE... So had a good play with prop yesterday, and very pleased. I managed to speak to a ROTAX tech and get some advice etc, and after getting her up and cruising I had to back off when she hit 115, as it was too lumpy to be going that fast! Anyways... More playing to be done! Means more flying! LOL! :) That can't be a bad thing!
-
Thanks Nev, Yep! The advise from Rotax is to run at about 5200 RPM. Just back from WOT and the prop coursed up to achieve that in the cruise. So going to play with that and see what I can see.
-
Thanks Nev, I just need to make sure I am not loading the motor up with RPM that is too low, and I think it's why Evektor moved the RMP and MP to the pilot side when they fit an adjustable prop!
-
No AutoPilot either.
-
Just in fight adjustable - not constant speed. I have to adjust pitch and throttle to get the best RPM for cruise etc.
-
It has end stops. But nothing in between. So you have full fine at one end and full course at the other. In between there is no predefined stops. Just a button that adjusts it between full fine and full course. So in cruse the pilot has to adjust the pitch to get the best RPM/pitch combo to get the best out of the flight. The two gauges needed for this are MP and more importantly RPM. With them on the right side and flat, it’s a PITA!!
-
The prop does not have predefined stops. It’s electric with a button on the dash with lights to show full fine or full course. To set the prop in the cruise I need to be able to see RPM and MP properly. Would be nice to have them right under my nose.
-
I do have an in flight adjustable prop - That's my point!
-
So... Let's reopen this topic once again.... So I can't angle the instruments - Cool. But can I relocate them? Ideally the RPM and MP is what I would like right in front of me, and in fact, Evektor made this very change not long after my bird was manufactured. The MP and RPM guages are in front of the pilot, along with Air Speed, Vert, etc etc. Now that would make perfect sense.
-
I’m confused. I have an MP gauge. Was the 2nd part of your comment mean for me Skippy?
-
Thanks Guys, That's pretty much what I am going trial on my next flight. Get to the cruise, and then adjust the prop and throttle to get the RPM sitting at around the 5000rpm mark, and get the MP to around the 26 mark. Then do some experimenting to find the best result. Cheers John
-
I think we all go through similar stuff. I was the same in my Sporty. I would get my money's worth and zig zag my way down the entire strip! LOL! Even on take off. You get used to it after a while, but now I have developed a bad habit of cocking up the landings. I used to grease them in, now I just can't seem to get one smooth. More practice required. Oh well.... means more flying required, and that's never a bad thing! ;)
-
OK... So having a look through the manual (Rotax 912ULS) I have found the following image. Now from flying around at cruise (around 5000rpm) my Manifold Pressure sits at around 23 to 25. So according to this image, I could course the prop up to 27. Am I reading that right? [GALLERY=media, 4045]Rotax-Cyl-Pressures by BirdDog posted Dec 30, 2017 at 7:39 PM[/GALLERY]

I have the endorsement and I know how to use it. Take offs, landings etc etc. What I want to know is how to get the "Best" out of it. Easy to say... course her up in the cruise. Fine for landing and takeoff etc etc. But I am looking for the finer details. @Camel - I am in Yass, NSW. My prop is factory fitted woodcomp. @Downunder - Its a 912 - so yep. 100HP at 5800
-
Yep! Sure is!

Hey all, So my Sportstar has an inflight adjustable prop, and up to now have not had much need to move from full fine (no X country Endo) but now that I am about to start venturing out, I thought it best to start researching its appropriate use. There is little to no info in the manual (It's factory fitted) and can't really find much online. I emailed Evektor some time ago, but no response either. :( Any tips, hints, do and don'ts would be much appreciated. Cheers John

I don't get to fly over this one much. ;)
