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
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.
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.
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
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.
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.
Hi Paul
I feel your frustrations and thankyou for your advice. One of the reasons my progress may seem a little slow is because I'm trying to make sure that EVERYTHING between the firewall and the panel is 100% finished before the bonnet goes on. Hell it's hard enough routing things through the centre console without having to be a contorsionist to work in the foot well.
How are your flying adventures going? Have you considered the LAA's mass balance mod?
Hi Paul
Thanks for your comments. I think by the time I'm finished mine, I will hate sewing machines. Show me some photos of what you have as hardly anyone does with their upholstery.
Thanks Paul
I am enjoying my upholstery work but it does seem to be ever ending. Up close you can see small errors that an upholsterer would'nt have made but I am happy and will be proud to sit in it knowing that I gave it a go.
Paul, thanks for the update on the wings. Maybe I can get back on schedule. Hopefully you won't spend as much time on the Center Spar as I did, that was my goal when I started posting my progress, that others would have an easier path.
Our dogs Bonnie & Clyde helped with the Upgrade. We walk every morning and that time was spent thinking about the Upgrade. All my "big ideas" came during those walks. It's all about templates.
Paul, I'm glad you are getting some benefit from my blogs.
I've been putting the fuselage back together. The little stuff takes time. The Rear Attach Plates went in easy, but getting the old ones out took some time and the 2 bolts are in a difficult place when it comes time to reinstall.
I mentioned to Phill to check the Center Spar Rear Attachment Uprights, they need to be .063, mine were.040. This information is in the Photo Guide, but not on the Drawings. The new set arrived yesterday. Once I get those fitted, it will be time to rivet the Center Spar.
Since you guys are getting something out of the blogs, I will do one more dealing with the small stuff, rear attach plates, seat angles, etc.
Hi Paul
Ha Ha. It sux I know but we are at the mercy of Sebastien Heintz. Not a position I am comfortable with either. I spoke to Al a couple of days ago and he is not to happy with the situation either.
I guess though we all have stuff to carry on with but just hate to admit it.
Paul, you asked "why are there solids on one side and pops on the other of 6-zu-2-1". I had to go double check and make sure I followed the drawings. That's what's on the drawings, A5 across the top, second line is Solid followed by A5's on the seat panel.
I'm struggling removing the solid rivets on the wing spar ....
Hi Paul
You lucky bugger. Double check and tripple check everything my friend.
I have to go to Maroochydore on Wednesday so I thought I would pickup the other stripes then and send them both together. Hope that is ok.
There you go, assumed I was talken to someone over in yankee land turns out they're right down the road. Definately welcome to come and have a look although there is not much to see at the moment have finished my empennage and not that far into the rear fuselage floor at the moment so it's a long road ahead still. Current contruction is at home in the garage about 10 minutes from work pretty tight setup but is working well so far. Fairly keen myself at having a look at your bird too, havn't look at a zenith with a jabiru setup as yet be happy to go for a drive to Warregul one of these days too.
Hi Paul, would be great to catch up, at this point I'll be sending the aircraft to Bendigo to burn off the 25hrs required, then bringing the aircraft back to Liliydale, whereby I'll take over and never come back down. Where is your plane hangered. Cheers.
Hi Paul, If you mean Cobra head on the carb air intake, I have run one and it was better than nothing and not as consistently good as a vane diffuser - which I currently use.
Mine is a cylinder of rolled al sheet 3" long the dia. to fit over the carb. The vanes are riveted across inside and 2" long, I have six (four will do)
This is the one item that helped even out EGT and hesitation problems with the engine when it had the first of the economy carb kits fitted. Of course we all know now that I was merely part of the R&D department trials and four versions later the carb kit is much more tolerant (and wasteful). The problem that it first presented helped me improve the air intake though.
All is going well we have 1/2 a wing to do and that is the end of the alum building. Starting to fit the Rotax 912s the dash and painting
The weather has been bad here as well and the locus are very bad. I hope over the new year things get better.
Cheers
Allan
I can help with your request. Flew model aircraft for 20 years and 1.2 mtr span rotor helli for a couple of years. Also have dabbled with heaps of the small palm size helli's. For the little kids, the cheaper the better to start with. Found some at big W for $15 ea one time. I will check into some for you that will be good value in both dollars and fun.
This was a photo of me flying my vintage Zodiac in 8 octas of cloud. Of coarse the camerman was strapped to the wingtip and happy to be there on such a hot humid day. Do you believe it?
Hi Paul, I was actually out at the dairy the other day doing some work. As for the canopy, it is still a fair way off yet... I am still trying to re align everything from where the last guy left off...
