Maybe it's about time you Mob ran for office , it's quite clear that you have all the answers. Ill vote for you .

I think your making it harder for decent folk to put up their hands to run for office , if when they decide to give it in they can expect the fond farewell they seem to be getting now ,. After all aviation makes us close and it's a shame we are starting to resemble a " civil war " type attitude , I think it's time that you great thinkers (and talkers) come up with some answers ,instead of rehashing the " problem " The crew that's got us thus far have after all been responsible for our flying privileges for a number of decades now , and I for one say thanks ! Thanks Guys and Gals Cheers mike Spello fixed - Mod xx

I was thinking of changing my name to Guy forks and succeeding Druidvale from Australia .after all ,all you need is a runway or two , hanger and plane , and a bit of sky to play in ! RIGHT! Although IDE Probly need a lawyer to do the paper work . Kas , are you interested , Cheers Mike

I spose we could just get rid of lawyers,( now where have I heard that before) ?

Hi Rod , haven't seen you for a while ? Hope you are well , I'm only days away from flying again , just waiting for the fuel tank slosh to dry , . Got my rego through yesterday , just in time , When you coming up for a visit ?? Cheers Mike

Dean went home because he wanted to , he worked tirelessly and he definitely deserves a break . I'm 58 , and Deans old enough to be my father !, although he doesn't look it And that's a fact . Cheers , young Mike .

I'm putting this on my TAIL , fin having it made into a left@ right hand sticker Cheers

That's true , I agree , I would balance all the bits for a total job , but balance is balance , if you carnt get the prop in balance , dynamically , that will show somthings amiss , when the props balanced with the engine runing doesn't that also bring every thing else into an overall balance ? I could be totally wrong here , it wouldn't be the first time . Cheers Mike .

The way things at going you'll need a tatto endorsement befor you can fly with it ( I spose you could always keep your sleeves rolled down )
-
Apart from crank balance , i found that a poor fuel distribution can feel like something's out of balance . Changing to multipoint fuel injection made a huge improvement in smooth running , Also balancing the prop on the engine ( dynamic balance) also takes pistons , rods , and every thing else that moves into account, Pulling down a new engine and only doing the crank only does half the job , Cheers .

What's the history with the engine?
-
That's right , if you change the angle of incidence ( what your calling pitch ) will only change the position of the fuse in flight , The wing will always want to fly at about 3 deg . To the air flow . In the situation you suggest ,as the aircraft left the ground (as you say 10deg pitch) it would pitch the the fuse down and Probly scare the "be -Jesus " out of you as the wing settles back down to 3deg ish Cheers Mike

I'm grab'n my 7th. April 2013 rego sticker and making the 3 into an 8 , stuff em , now it's registered to 2018 ,then 2 months later at YBUD ....
-
Said I'm still waiting on my rego and I'm about to .........
-
Have you got you rego yet?

Coke can is .010 thou on the knocker , I've used it for shimming jobs , handy stuff , I've also just sloshed fibre glass tanks with a product called "BILL HERSCH" " gas tank sealer" , it's tested with ethanol , & alcohol at 80% for two years , a place in Sydney sells it , don't know about 2 stroke though. I got 4quarts on e bay for $ 123.90 Google " fuel tank sealer , for the specs Cheers Mike

Preflight Inspections - look harder!
AVOCET replied to Jabiru7252's topic in Aircraft Incidents and Accidents
I've found on the jaby type U/C that grass or rough ish dirt strips really vibrates the U/C ,on the avocet you get a good view of the wheel & leg and i was suprised how violent it moves back & forth ,even on the taxi , it looks like the bolts are loose . I would think this has a fatigue effect on the bolts , as I have replaced several over the years with slight bends . It used to be the back bolt on the old Jabys Doesn't seem to be as much of an issue if they are only used on the Tarmac . Cheers Mike -
SDS is a grate multi piont FUELINJECTION system and Ross is a great guy to deal with . The difference it's makes to smooth running is to second to none , coupled with liquid cooling , seems to be the way to go ,

Bex better, one tablet add water and fuel ,then fly ,,, I feel better already
-
Yes did miss the smile , I wasn't trying to be sarcastic , just keeping it real .ive had 1500 hrs on jaby engines since 1996 ( and no real issues ) although I'm Probly a bit bias , I built the first patterns for the original jaby engine ,( gee that brings back memories ) Anyway, I think what your doing is absolutely great , And if your looking for any help , testing , flying , installations , ect . I'm interested in engine options for further development for the Avocet & I think it's important to support Australian endevour ,( just got a set of EQ headsets , go Aussie go ) My be we could talk ? Cheers mike

Good luck &cheers

Who what ware when ????

I agree , I've had the same issue when test flying new aircraft , it doesn't take much mis alignment of the nose wheel to rudder to upset the balance , it's even more pronounced with a front spat . What I've done is get the plane to taxi straight with the rudder peddles in the neutral position & then offset the rudder 5 mm to the left or right ( depending on tractor / pusher ect.) flight test , and adjust accordingly ( you have to think it through which way to ajust )until the balls in the middle . This assumes that the wing & flap incidence are correct Cheers Mike

He's right , keep it up , aviation needs thinkers as well as doers , it's a good Idea and would not be that hard to work out the stresses & loads for a given prop size / boom size ,& such .(I know the "such"is the tricky bit) The thrust bearing for a crank shaft isnt that difficult to reproduce on your boom , chech out the jabiru manual ,( that'll Probly keep you up tonight , sorry,... not) .whatever you do you'll have to incorporate some form of lubrication IDE imagine ? My Son has designed a planetary gearbox for contra rotating props that mounts on a boom . He has a working virtual modle that has impressed his mech engineer uncle ( believe me that sayin something !)we are going to get (build ) a 3 D printer to make the prototype So as soon as the Avocets up & sorted ill be starting on the light weight motor glider. I need something cheep to run & fly / glide around the Flinders on those glorious days .ide really like to go electric , or solar Cheers
