I would assume the nose wheel and the rudder can be adjusted independently of each other. So, disregarding the rudder, adjust your nosewheel so you taxi straight ahead with the pedals neutral. Once you're happy with that, adjust your rudder so that at cruise power there is no yaw. Remember, maladjusted ailerons or flaps will cause a yaw, but with roll. Under high power, a yaw to the left is normal, under a glide, yaw to the right is normal. Remember when your instructor kept yelling "MORE RIGHT RUDDER!!!" as you gunned it down the runway during those first few hours.

No offence but I think your rudder advise in a bit sus. The rudder will move to the point of least air resistance. The only way to get the rudder to reduce in flight yaw is to :

• Keep a heavy foot on one peddle - fatiguing after a time
• Use a spring/bungee on one control cable/rod - works but peddles uneven in balanced/cruise flight
• Use a trim tab - either in flight adjust (additional complication) or a fixed tab adjusted to cancel out uneven action. The latter will require an adjustment to peddle hight so that when trim in effect peddles even

Its not so easy to diagnose an unequal control input -

Rudder may induce a yaw but this will progress into a role

Ailerons will role without corrective rudder

Separate miss rigged elevators will also cause role/yaw

Flaps - never had this but assume will act much like ailerons

A projection from the fuselage/missing wheel spat, etc may also effect trim

what's the tendency to yaw say at 50, 70, 85 , 100% power etc ?  

any springs holding the rudder (pedals, wheel) centred? ) spring fallen off ? (happens in Jabiru's with big boots on ) 

 

Tendency to yawn when your big booted spring falls off????🙂

You forgot loathsome, blame shifting and talking of blame shifting Scotty from marketing has been absent. One of his very few public appearances he said the mission in Afghanistan was accomplished so all OK. After the Russians left there 20 years ago the place was overun in a couple of weeks, now Scotty from marketing says it happened too fast to try and help  those that helped us. Those that don't learn from history. Thread drift, spin is the connection.......

There is absolutely no excuse Australia lack of moral responsibility in this matter. I am ashamed of our responsible  leaders.

Logical planning would suggest that all Australian helper/supporters & their families should have been given the opportunity to leave Afghanistan BEFOR out troops departed and we closed our Embassy. Even if the Taliban had not surprise themselves and the political leadership of the west, the absence of our troops/administration would have made getting our friends out, very difficult.

Fundamentalist groups, of any/all persuasion, are very very bad karma. In general they answear to a higher authority (than the law of the land), as articulated by their leaders (priests/rabbis/mullahs, etc) that absolves them of responsibility for any deed/action that they deem to be handed down/sanctioned by their spiritual leader(s). So that Jewish mob probably all feel that they have done no wrong. Throw the book at them and then some - send a message to all similar groups that dissent of this type will not be tolerated.

It seems to me that you are ignoring the pioneering (successful) work of others, who have opted for the Rotax 914.

Why reinvent with a smaller wheel ??

A couple of good things about the poms tho... 

Recently, I heard an aboriginal activist ( well actually  he was as white as me ) being asked about what other colonial power he would have chosen instead of the english...  he was stymied for a reply.

On similar lines, apparently the blacks in South Africa supported the english  against the boers.

 

Its all relative and at different times in history the same colonial power can be positively bloody and at another time, almost an angel of mercy & good governance. Don't forget it was the British in South Africa who invented the Concentration Camp

I have experienced truly violent turbulence in the vicinity of Katoomba - still shaking when I got back on the ground at The Oaks. I now approach that area, ready to reduce power at the slightest hint of vertical air movement.

On the other hand - years ago, when returning from Cowra to Condobolin, in a C172, I had entered a very smooth (no violent movement)  powerful updraft that had the aircraft climbing at idle power, at at least 1000 ft /min. Seconds later entered the down draft, unable to maintain altitude at full power. At no time was I as terrified as the later encounter over Katoomba.

I suppose the answer is Yes, but you should be using your feet to control the rudder, not letting it and the nosewheel do whatever they like.

Are you flying the plane or just going along for the ride?

Come on Yenn, "dont come the raw prawn" - many aircraft (probably all GA & above) have one or both longitudinal & lateral trim. Trim can be pilot adjusted (in the air) and or fixed. The latter is usually a small metal tab, fixed to the trailing edge of the control surface that the pilot feels needs some "help", that can be adjusted by bending more /less to get the desired effect. Whatever system is used the desired outcome is a a centralised/light control at given air speed & aircraft load.

Just had a random thought - this would only work (if at all) for a steerable nose wheel set up - if you wanted to apply a small amount of rudder trim. This could be archived by rigging the rudder/nose wheel alignment so as to apply the trim, thus removing any need for a fixed trim tab.

Yeah well the powerful (countries) have been bulling the weak since the begging of history.

Look what the English did to the Irish - genocide, forced migration, land evictions, starvation, denial of education & religious observance - that in the now distant past.

In more recent times: The British imprisoned (judge only courts) political dissenters, completely innocent Irish nationals, shot demonstrators and generally behaved as a hostile colonial power (true they were provoked).

Did you get anyone looking at the aircraft at Leongatha?

If not l should be able to arrange with a couple of pilots l know down there but dont know how to person to person to speak with you,

Yes & No BRL - made contact with  several people (unfortunate all acquaintances/friends of the vendor) who are being very helpful. Still would like an independent eyeball on the aircraft.

I think if you click on Skippydiesel you will get directions to email me

Perhaps those super-Rich will manipulate the ' genes' of the poor, to make the old slaves thankful to their master.

It could even be happening today. All the additives in everything we eat & drink. 

Didn't it get used in the war to stop " randi " soldiers. something in their mashed potatoes.

spacesailor

The best way to enslave the mases is to get them all into the middle class.

The poor have nothing to loose and may revolt.

The rich give nothing and control those who aspire to power.

The middle class have no time to waste, everything to lose, paralysed by the  taxes that support the nation and paranoia that they may end with nothing - so they do nothing - sound familiar.

There is no plot, just human nature.

This sounds like a preamble to a conspiracy theory - colorless fuel is easier to adulterate/substitute

Roger that Walrus - are you offering your services as per my request?

Add corruption……

Corruption is the parasite of all human systems/organisations. It seems to flourish under the extremes of left & right but is never absent where the quest for power and financial gain(very human conditions) are centered. In the middle ground there are frequent attempts to address corruption, not so at the extremes.

Corruption will be with us, as long as we remain homo sapiens. It may become redundant when we evolve into homo superior and every individual has a highly developed social conscience. This will be when we no longer need governing or even laws to guide us. Fantasy perhaps but we already have the crude ability to manipulate the gene. So when will the very rich start to influence the future characteristics of their children ?

Also you forget that Britain had a massive war debt after WW2 which had depressing effect on its econamy.

I am concerned by some of the respondents on this topic.

There seem to be a minority who have swallowed the anti Communism propaganda,  that originated with McCarthy in the US and bubbles away under the American psychic to this day, so much so that they are unable to differentiate between Socialism and Communism. THEY ARE NOT THE SAME !

They are as different as Fascism & Conservatism/Capitalism.

True, there is a continuum from Fascism on the extreme right, to Communism on the extreme left. Some would argue its more of a circle than a line, with both extreme's exhibiting many of the dogma/behaviour of the other.

The point I am trying to make is that for the most part liberal democracies occupy the middle ground, with occasional minor shift/moves (some call them corrections) in on direction or the other.

Socialism gave us public health, the dole, work laws, leans towards accountability, caring for the underprivileged etc etc. Capitalism gives us a strong dynamic econamy necessary to support the welfare state - leans towards unaccountability (secrecy) and support of the wealthy . 

We are lucky to live in such a state and should protect its values vigorously .

Roger??????

I think the closing minutes of Prof. Doherty's interview, where he comments on the extremist capitalist(neo liberalism) approach to politics/society, is what is most striking. He condemns this one eyed simplistic approach - it is pretty well encapsulate by the concept that the market (money) will guide/dictate policy. Trump, Thatcher, Johnson and quite likely Scomo would seem to be adherents. The best example, of the long term application of this idea, is probably the good old USA - a societal basket case if there ever was one.

I recently replaced the battery in my Foxbat like for like with a Fusion 

CBC12V22AH. 6kg. The Rotax  is a 912 ULS 100HP

Bought it on eBay $84 delivered

I could not find the CCA for this battery.  This makes it hard to compare with others. 22AH very nice though.

Great price

I am trying to purchase an aircraft but due to the travel restrictions imposed on me (& millions of others) by the Sydney Basin CV19 lockdown, I am unable to even do a cursory inspection of a prospective aeroplane.

I am currently interested in, an almost complete, plans built aircraft, located in Leongatha, S. Gippsland and would like an interested/cooperating pilot(s) in the area to have a look at it for me. I am not asking for a detailed inspection just an informed eyeball look over.

Should the report be favorable, the next step would be to engage the services of a L4/LAIM qualified person to do the definitive inspection.

If you would like to help, please make contact through the person to person  facility on this Forum.

Plus one for the cranking:

There is no electrical connection on the 912 between the battery and the ignition systems.

The electricity for the ignition is generated by coils in the stator as the engine rotates, and the engine must rotate at a sufficient speed for that to happen. So, to start well and reliably, the engine needs to rotate briskly.

Agreed 110%

Hence the advise to purchase the, most cost effective, battery with the most cranking amps (taking into account weight & dimensions). Battery's designed for large capacity motorcycle starting, are your best contenders, being compact, light weight, vibration & spill resistant.

Got the rubber wheel, clogged up pretty quick, because it’s under the wing makes it hard to soak it ,so far metho soaked rag and fingernails ,  been at it off and on for hours , about half way there, thanks everyone for the advice 

Yeah! have gone down and rejected, the rubber wheel path myself - if its that "hard" take the wing off and flip it on a stand/table.

Ha ha! good old Bunnings reinvented the bit of gal pipe driven into the ground.

Already suggested - "Its probably overkill but you could drive a pipe/picket into the ground (preferably where moisture concentrated). Run a cable, from the picket to the drum being used, clip on to drum with HD alligator clamp/clip. From drum to aircraft earth point (exhaust pipe if no dedicated earth point.)
