put some pics for up you

 

It's really a thruster doing what thrusters do. You've got a high thrustline and without the fan blowing air over the rudder it sometimes doesn't do much for directional authority. I personally wouldn't fly one from the strip you describe, till you are very familiar with it. It's too narrow.. Nev

I wish........I used my neighbours home made 3 point grader origanally but boke it on the last pass..he also is 10 km away and his tractors and ROCK ROLLER(thats what I really want and need ) are too far out on his property ,so I only have 1 option ,thats to first shovel and pick gravel and fill the 6x4,,then un- shovel the trailer of gravel on to the run way.when iv done 2 trailer loads which gets me 6 meters I then shovel a load of bitumen and lay that over the top then roll it with my toyota corolla..lol ...I have finished 170 mtr of the 300 mtr strip ,and today I started the teediest task of removing rock by hand and shoveling the dirt from the bank then use my hand mower to cut the weeds and end up with an extra 20 ft width of dirt/weeds..I manage to get about a 100mtr of 1 side done in 9 hours. ill try and post a pic..but be WARNED my strip is not for the faint hearted...unless you fly models....lmao

 

pics relly dont do justice but any way they show 150 mtrs of unsealed compact bitchumen and 150 mter of runway ready for gravel and bitchumen..no pics of widening yet....I have about 80 mtrs to go and now widen the whole thing so will be a couple months off finishing...ahhhh ....what a way to kill time.....bugger ............yep all by hand ,by myself, just me and my shovel,all alone,,no one but me,,,yep just little ol me...any one getting the hint??? lol

 

take it easy

 

 

 

 

 

 

 

Hi Guys,went out to the strip early this mourning to widen the strip (spent 9 hours on the shovel and pick and manage to remove rocks and gain an extra 20 ft width for 100 mtrs,only500 mtr to go).

 

will bring the strip to a total of 60 ft wide,thats a 20ft wide strip with 20ft either side for run off. should take me a month or so every day with my shovel and pick..lol hmm dreaming of a tractor...

 

oh well better drain the fuel out me beast could be a while..

 

p.s spoke to Ed..cfi at Goolwa and he is going to get back to me with a number for a guy from Shepperton who can help with lessons in a thruster... sweet biscuits batman!!!

 

 

Hey every one, whilst running some ground test yesterday I exspierienced the loss of contriol Ive have read about in both private and Tony Hayes writtings on the Thruster. I have found no reference on why this happens but I m alomost certain I know why this happens..O k first lets look at the insedent:

 

Condition: calm, on off 3 knott cross wind.

 

Strip: very narrow(20ft wide) with 1ft high bank either side full of rocks and boulder as runway has been graded into lime rock so NOTE their is no room for error must stay pretty strieght down the strip.(no probs normally)

 

Aircraft: Thruster t83 new adition and have never flown this or anyother thruster.

 

.I had performed a number of low to medium speed taxi tests with no problems, after 20 mins I increased the power to around 3/4 and pushed the stick slightly forward and let the tail raise for around 25 - 50 mtrs before de-cellerating and pulling the stick back to settle the tail wheel and contiue a strieght taxi.At this stage all good and feeling conferdent.

 

For the next taxi test as planned I would open full throttle let the tail raise taxi at high speed with forward stick ,when approch stall speed(aka lift speed) I would de-cellerate and roll out ..No worries!!!!

 

Insedent: As full throttle was applied the tail rose instantly and the little beast took off down the strip with an allmighty roar. I only rolled for about 25 meters when the bumpy runway become completly smooth...Oh shit I thought (,as we all do at this point) I still had the wheels on the ground but was starting to float in ground afect ..so I instantly closed the throttle and then she spun to the left....with full right rudder (im pretty sure my foot went threw the floor of the pod..lol) applied nothing happened, no time to plant the tail just ploughed into the inbankment in a slight right hand skid as the nose ploghed into the ground I tried to kill the engine (PROPELLER ...OH CRAP I THOUGHT THERE GOES ME BROLGA).. but as the tail rose to about 75 deg and im now staring at the ground she fell back down..ever so softly...ah thank f*&^... for the high engine mount..

 

Conclusion: after a thourough inspection and plane deemened all OK i ran some more test to work out waht happened and descovered (Guessing this is proberbly all ready known?) that what happens is the following:

 

as the airflow gains speed it gets to a point where the tail plane has sufficiant airflow for lift IE.. the tails up in the air but not enough airspeed for Rudder control...

 

So in the begining the air speed was good for steering on the tail wheel and then tranferred to rudder as the tail rose all ok,, but as I decreased power completly with the high amount of drag, the plane instantly lost enough air speed for rudder controll and as I had the stick slightly forward tha tail up in the air I also did NOT have tail wheel control either.Hence a total loss of controll.

 

REMEDY: pull the stick back whilst clossing the throttle to bring the tail wheel back to earth for some steering controll..

 

Know has any one else had this problem and does that sound right or is thier somthingwrong with the plane or am I doing wrong?. and more the point is this going to happen after touch down?

 

 

Thanks everyone.. will run some taxi tests with the 2 fuel pumps...I'll see if she runs without the electric fuel pump. And yes it has a return line to tank and has a pressure valve fitted but I have a feeling it ran a rotax at some stage(as the manual for the plane also has a rotax manual with it?).

 

 

Hello ,as im not familure with the old belt drive robin engines im wondering do I switch off the electric fuel pump after climb out and switch back on for final ?or do I leave it on during the flight? I presumed I switch it off (as per above) but was told I should leave it on during flight by the ex-owner!( barley- licenced ----out back flyer)!!! he said he leaves in running the whole time the engine is running!

 

I would think its only to prime the engine? as my old rotax 447 just had a boat type hand squeeze prime pump - NO electric fuel pump

 

Thruster t83 -

 

 

The old Bunyip in a sorry state before sale...

 

 

 

The Bunyip may have been a problem however the Tyro is a good basic 95:10 and I believe that to this day is the only fully certified 95:10 aircraft.Alan Marriette, previous Tyro owner.

I agree in that the Tyro is a good basic 95:10,was going for one, but got a better price on the thruster also a good 95:10 ( and not to different to the tyro,,) theres a Bunyip just up the road Here still flying (from a farm) has had the tail bracket replaced and apperently some shot gun pallet holes fixed(the next door nieghbour got sick of his low level sheep swooping..)..lol

 

 

on the early single seaters the the serial numbers were stamped on the end of the aluminium engine mountscheers corky

Hello,just did a complete and thourough look over, could not find a plate still and also looked for rivets or rivet holes and nothing?I should mention its still running the origanal fuji robin 50hp and appears to have origanal alloy engine mounts..what has been removed and replaced were the wing box's,new mild steel fitted(raa phoned and noted)..I dont have a lot of history other than it was inspected in 1990 at mt,gambier by a Lyall Sharam then in 2009 it was inspected in nsw(somwhere near Sydney),wing box replaced and flown(total 3.5 hours logged),I bought this from another owner with no log book,no licence, (as he was a farm flyer who flew it on his own property{apperentlythe raa rules state no licence or reg required if flown on and within own property} wich he flew the day of purchace. other than that all I know is its a modified T83, one of 49 built...mods are : endurence tank and spoiler fitted, rear cabin new full alloy sheet fitted(to fill in cockpit) new doors fitted and a 3 blade brolga fitted..I was yold this eas done very early in its life..?

 

 

I tore my heal off and crushed my ankle(calcaneise). unfortunatly it was mis-diagnosed and after 3 years of agony they did a sus-taylor fusion(can move ankle up and down but no roll..can be tricky with a rudder BAR.) still in agony every day walk funny and can't kick the footy with my lad....oh I did it on my dirtbike ,used to be a freesyle rider this is me last year ...yes with the fusion as I had the fusion 9 years ago....I sold my bike a couple of months ago to buy my plane ...but not really a safer option!!!lol

 

 

Thank you for the advice. I was thinking the same thing when he stated that it was never rego'ed and flown unlicenced. I was only going to see if it sold or not, if it didnt I was going to offer him what it was worth in scrap only. I realy want a 2 seater, Ill keep saving/dreaming/hoping to win lotto!Scott

Ha Ha funny that was mine!!!I was the who sold that old girl.....I was the second owner and never flew it past a few bunny hops as It was not airworthy..they do have a connection with the tyro both built at goolwa ..theres only three left for good reason...the tail fell off if not re-bracketed and the wings constanly tore rivetsand cracked, and the frame pod mount cracked etc....ahh glad for my new thruster..

 

 

Hello during inspection we could not find a i.d number? it was on the intrument panel in my old Bunyip but can't seem to find it on my new Thruster.it may have a new insrument panel as it appears no be velour on masonite.and not alloy.

 

P.S I m pretty sure I'v got a new world record!!!most amount of dirt and gravel shoveled in a week..have to had dig/shovel dirt in to my 6X4 trailer then shovel it back out on to my Lime rock strip..im half way at 150 meters has taken a week and have shoveled.dug and mined 76 trailer loads working from 5am to 6m pm evrery day ,having a day off to rest my back and my cripped fused foot...are 1/2 way and she looks pretty good..wellllll..hmmmm;good enough

 

 

Nice Thruster... How much room is there in the cockpit?

I think it was made more a miget,,...I mean "little persone"... im 5ft 7" and wiegh 68kg and just squash in..have to leave door open to put the harness on and then close the door..lol..

I like em snug.

 

 

lessons in a thruster.

 

 

Hello, Ive just bought a thruster t83 ,fully enclosed pod long range tank...just had the inspection done and ready for flight...but as i have a rough narrow strip and have never flown in a thruster or a tail dragger I would like some lessons.

 

So does any one know where I can get lessons near Murray bridge south oz or any where?
