Por favor, what would be the link to Spanish outlet, gracias.

There are two kinds: Engine Balance Master fitted on Fly Wheel Props Balance Master fitted on Gearbox Flange behind the Prop https://www.leadingedgeairfoils.com/engine-airframe-accessories/balance-master-products.html Are they doing the job, are they any good ? Please share your experience with them.

Well Guys, here we go. I lifted both ailerons up a bit, that is 3/4 of inch for sake of it. Very experieced CFI an Pilot Examiner K.W. at Lynfield tested it there and he said it is much better. Actually, he said, the problem dissappeared and the "aeroplane is now flying like a Thruster". Thanks to you all for your inputs. Incidentally, this Thruster 10-1312 is now for sale at Aviation Classifieds, because I fly Skyranger too. Keep speed, Tony.

Thanks Don. Originally, I had both Ailerons slightly (1/2 Inch on trailing edge) down, thinking I have a sort of good Flaperons setup. But, the aeroplane was feeling "wobbly", so I change it, now they are lining the bottom with the bottom of the wings. Still, sometimes fish tailing..... CFI tested it and made the same comment. Anybody has better setup ? Thanks Tony

Hi Guys, I refurbished my Thruster 10-1312, SG85 and flying it. BTW, it is for sale at "Aviation Clasifieds"........ How much is the Aileron Drop, IF ANY, that is the question ! I have no experience it this, but the aeroplane is sort of not happy sometimes, me too. Washout was done very carefully at 30mm both wings. It feels like it has more than one equilibrium in balace straight and level flight and it is looking for it. Kind Regards Tony (Milan) Vlasak

And there is no balance weights.

I did not bother yet to move the stick left or right more than necessary, which was not more than 1-2 inches. I did not try any turns more than 15 degrees. The feeling was rather alarming. But, on landing there were no problems using the rudder and elevator keeping the wings level. The landings were actually real good. Because the Teleflex Morse push-pull Cables are now 32 years old on this aircraft, I think about to replace them. Thanks Guys for your input !

Hi all, I finally finished the reconstruction of my Thruster SG85 single seater, which I never flew before. Test flight was done by a very experienced L2, who said the aircraft is beautiful, but the ailerons are bit heavy. I took it up myself and yes, they do feel heavy. I had a good experience in Thruster T500, Lightwing 912 NW and TW, Drifter, Jabiru 230D and Jabiru 170. I have never experienced such heavy ailerons in my 350 hours flight life. The feeling is like something is holding the stick, it goes to center, but I must help it. The rudder and elevator work perfectly and very nicely to work with. I am suspecting those push-pull Teleflex Morse Cables, when on ground however, they do not offer much resistance. Any ideas ? Tony

I do not know why and how the RAA can be blamed for this. ALA is "advisory only". Therefore, in a nutshell: What is allowed to Gods is not allowed to Ox.

24 Million Salary ? Where they breed ?

If they crack they do bear some load.

What they are going to do on landing and take off ?

So, which way the prop on this particular machine is turning ?

Good point. I can't really see the r/h flap down. Can you ?

Fantastic video Rodgerc ! Taking off the ground a Tail Dragger in 3 Point Landing Attitude and bouncing the Tail Wheel back on grass...........that great angle off attack on take off would not be too good for any light aircraft including Nose Wheel.

Fantastic, thank you !

BTW, someone got a copy of the Manual for the type we are talking about ? Kind Regards,

I got it registered as follows: Database Details for Aircraft: 10-1312 Manufacturer: Thruster Aircraft Model: T85sg Serial No: 312 Certified: no Manufactured: 01 Jan 1990 First Registered: 24 Oct 1991 Seats: 1 Weight: 156.00kg For renewal of registration they now require: Photographs of cockpit Max Take-Off Weight and Warning Placards. Photographs of registration numbers under the wing and both sides on vertical surfaces.

Hi Guys, Who knows what is the MTOW Single Seater TSG85 (25.6" Clipped Wing) ?

Hi Guys, We have scored 204 views and 20 replies in this problem and we got some answers - thanks to everybody ! In conclusion, it appers to me the Thruster wing may be rigged to 0+ (zero plus) geometrical washout. How much the value of PLUS is ? It is rather a matter of a taste and experience. At this stage I am going for 1 and 3/4 of a degree which is 40mm measured vertically. Peter G, thank you for taking the measurement from your machine. Gorky450, the length of the struts is affected by the exact position of the predrilled holes for the top brackets and the bottom ones, which can be different type to type. Your position of your brackets may not be the same as on my type. Never the less, just to get a picture for the material needed as it goes as follows on mine: Front: 1)Top solid round alum plug 80mm long x 40mm Dia, 35mm Dia inserted into 2) Alum round pipe 35mm inside 300mm long with inside rectangular timber inset, alum wall 1.5mm. The bottom end flatten to oval inserted into eliptic strut 3) Alum strut eliptic 2mm wall 25mm x 70mm - circumference 165mm at 2125mm Length accomodates at the bottom the: 4) As Item 2) but Length 450 with STEEL insert of 1.5mm wall, all that goes into bottom bracket. Rear: 1)Top solid round alum plug 80mm long x 40mm Dia, 35mm Dia inserted into 2) Alum round pipe 35mm inside 400mm long with inside rectangular timber inset, alum wall 1.5mm. The bottom end flatten to oval inserted into eliptic strut 3) Alum strut eliptic 2mm wall 25mm x 70mm - circumference 165mm at 2500mm Length accomodates at the bottom the: 4) As Item 2) but Length 350 with STEEL insert of 1.5mm wall, all that goes into bottom bracket. Precise rigging occurs by shifting all members of this whole set inside of each other. Brackets set first, holes drilled last. I have no 'jury struts'.

Hi Guys, I am very gratefull for all your inputs from every each of you. I think I have to disclose a bit more about this particular one seater Thruster 'T85SG' I am reconstructing. It has the dihedral 50mm at the leading edge. (Only.) What is alarming to me, it has got a NEGATIVE (!) washout so bad so the ailreons appear to have NEGATIVE dihedral by 50mm. It still was flying, but not by me. Now, everybody on this post would agree this is absolutely wrong and I have to do something about it. It is very easy to extend the rear struts only if I know by how much exactly. Talking degrees, one degree represents a shift up of trailing edge by 22.5mm. Measured as cross section as a difference in Angle of Incidence that is. If Peter G can measure that in degrees please do so. Thanks, please keep going here. Never assuming anything Tony

Hi Guys, I am nearly completing restoration of my Thruster 85SG 'clipped wing' 25'6''. I am looking for answer to the question: How is washout achieved on Thruster wing ? More specifically, is there any structural washout, if yes, what is the value to change the angle of the incidence on the tips. Thanks in advance to your inputs. Tony

Did anybody noticed the machine crossed the shadow of the pole just before it collided with. Which means.....

As it shapes-up now, I would hold on the old tank with the original fairing etc, but make an insertion tank inside of it from aluminium, using the old tank as a bracket.

Right, OK, It looks like I'll take the old tank to somebody who can make exact copy with the fairing in aluminium incl. holding points etc. Thanks for that.
