Did it. Fin in. Read "Above all the best mod for Bing".

Paul, I think this is a common problem. However, I cannot get most pilots to talk about it. The only fix that I have not tried is the metal fin in the intake hose to stop ram & turbulient air of the sensors in the intake. Hope to get more feed back.

Paul, I am looking at you cowling and see two N vents on your pilot side. Did you move the cabin heat vent or is that a later model than mine? Mine has one vent on each side.

Hi Paul

I dont feel anything strange with the rudder but I have put silicon spray on the nylon bearings and on the cross bar that the rudder uses to attach to the nose wheel

Hey Paul...

Michael is there Fri, Sat, Sun - At Natfly

Hi Paul,

A typing msitake, my main jet is 255 not 245.

Cheers

Hi Paul,

You'll probably find that your CHT figures are at the upper limit of what is allowable, and if you talk to Jabiru (not that they are very helpfull at the best of times) you'll find that they will tell you to reduce your temps.

Hi Paul,

Sounds like you are getting similar figures to me previously.

Yes the Patroine prop will make the world of difference as far as you RPM's go, mine will now rev to 3200rpm full throttle strait and level. I have it set at 16 degrees of pitch at the moment which give me 110knots at 2650rpm. I typically climb out at 2800 rpm at 80 knots, one up, gives me somewhere between 1000 - 1200 fpm in climb.

Another big advantage of the prop is that it is much smoother in flight compared to the jabiru prop and also less noisy..

My engine also ran rough at full throttle, what jets do you have fitted?

I have the 245 main jet and changed up to the 290 needle jet, also there is a different needle that you probably need to install, talk to Jabiru for a new needle and jets.

Try this quick test, go to full throttle and pull on your carbie heat, you'll probably find that the engine smooths out, which means you are running too lean.

Cheers
Eddie

The Rotax has preformed great no heating or cooling problems once I fitted the cowls correctly
I have heard that the Jab has a bit to much power but the the Rod Protroni prop seems to fix the prolbems
I have heard that a few people are working i=on the Jab cooling problems too

Once the weather sorts it self out I will contract you and i will fly over one saturday I also have to call in on peter at Leongatta too

Cheers Allan

Hi Paul

Yes the first flight is a strange flight, scary but also something you cant put in to words

what airfield do you fly out of I might drop by one weekend ?

Allan

How's the Flying going?

We seeing you at NATFLY?
