Thanks Nathan, Yep! My Motor RPM has direct connection to how fast my prop spins. Might is not constant speed. Just the pitch is adjustable. Cheers John
-
Thanks Nathan, Great info. I have been talking direct to ROTAX and they have been a great help, and he put more emphasis on making sure I kept the motor RPM around the 5300 mark. I guess, if as you say, the prop RPM falls with an increase in pitch, so does the motor RPM fight? Hence the need for more power (more throttle) Roger (Rotax) has recommended 5300 RPM on motor, with 26-27 on the MP. And that's pretty much where she sat last flight, but had to back off, as it got too quick for the conditions I was flying in. It was not full pitch nor WOT, so not sure what she would actually do at full beans! LOL!
-
Yep - Same. My Maintenance Release is kept in the binder with the logs on a separate sheet, and is looked after by my LAME. :)
-
The sequence would be... Take off - Full fine - After climb, reduce power to bring the RPM back from max (Say 5300rpm) Increase prop pitch a couple of clicks. This will bring RPM down as it courses up. So increase throttle to get RPM back in range. Repeat and rinse! Then once cruising and you want to come down.... Decrease throttle, and reduce prop pitch. As the prop is reduced in pitch, the RPM will increase. Repeat and rinse! Take off = Full fine. Landing = full fine. Cheers John
-
Yep. That’s what the rotax guy told me. Get up and into cruise. Backing to get stable, then course the prop, increase throttle, then prop, then throttle etc etc until ten desired result is achieved.
-
Ahaha. Yeah. I like to be organized.
-
No probs. If you want the raw Excel let me know. Happy to share.

Hey @cscotthendry, Thanks for your example. I took some ideas and came up with this. Fits my binder like a charm! Thanks for sharing Sportstar Logbook.pdf
-
It's all good lads. Like I said, Evektor are coming to the party. I have spoken with them and the Authorisation should be with me next week. :) I agree with illegal mods - just frustrating - hence why I have gone to Evektor.
-
Yes it. And yes please that would be great. Do you need an email address. I can PM to you. Cheers John.
-
Nice! They look good! Capture all the bits you need. I am thinking like you, that I will make my own up. More flexibility that way! Thanks heaps for that!
-
@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!!
