RE: BJCraft Episode
The DTFS design was indeed new, in 1987, when Wolfgang Matt started using his Saphir. As I recall he told me that the wingtips improved snap-rolls and handling in turbulent conditions. Anders Johansson

RE: Sebart Wind S Pro
I would very much like an explanation of what Hezik means by roll-instable. I have flown my Wind S Pro more than 600 flights (P11, F11 and P13). During 32 years of competing in F3A ( best result 6:th place at a EC) I have never flown a model more stable than the Wind S. It is extremely good in windy and turbulent conditions. At several competitions the judges have commented on the stability of my model compared to other types of models. My setup is nothing out of the ordinary. The CG is at the back of the recomended range. Rollrespons is smooth and predictable with very precise stops. It rolls straight as an arrow (no pun intended) with minimum compensation.

I have been using Futaba BLS153 servos on aileron in my Wind S Pro the entire season with no problems. I fly F3A P-11 and F-11 schedules. The F-11 contain 9 snaprolls. My flying style is a little bit far out and fast so I don`t go easy on the servos. In what situation did the shafts break? Regards Anders Johansson

RE: Sebart Wind S Pro
I trim my aircraft to fly hands off in upright flying. This means I have to push some down elevator when inverted. With this setup there is no mix needed for knifeedge. The Wind S Pro handles integrated rolls very well. The narrow fuselage and its crossection helps create knifedgelift. The most important feature is the landinggearfairings that adds sidearea and helps straighten airflow. Putting a T-canalizer on this model is not needed. I fly both P11 and F!! and is perfectly happy with integrated rolls. Regards Anders J

RE: Sebart Wind S Pro
Since I painted the fuselage myself there are no dings or dents. Only one rib can, just barely, be seen on the outside. You need correct light an looking in the right angle to see it. My fuselage was rather light, can`t remember exactly. I added 85g of paint and clearcoat though. Total weight of the model with 5200mAh 35C batteries is 4780g. I have no wingfences. The Gaudius is one model I`m looking forward to see at the Nordic championchips this summer. I compare the Wind S Pro to all models I`ve flown and seen in action during 30 years of national and international competing. Last season I placed second at the Swedish Championships flying The Wind S. First place was won by my training friend also flying a Wins S. The way the rudders are hinged is the thing I like least on the model. I would prefer to be able to seal the hinges. I can`t say I notice any drawbacks i flight though. Off course everyone is entiteled to their opinion. Since most complaints regards the finish of the model I´m lucky since I did the painting and covering myself. I`ve read a lot about the wind S Pro on different forums. It`s quite obviosly not a model of Oxai quality. A lot of the complaints are nitpicking about problems that are easily fixed. I have built two models and seen four being built other. So I have som firsthand experience. That the flying proprierties surpass the building quality is a statement a can agree upon.

RE: Sebart Wind S Pro
My model now has 309 flights. It is in condition as new. I replaced the hinges from the beginning. The holes for the antirotation pins where treated with a thin layer of medium CA-glue and shows no sign of play. I am totally in love with this airplane. It suits the current FAI-schedules perfectly. As for speed I would not want too fly any slower than I do, but then again Sweden is a windy country. Which brings me to windy and turbulent conditions. The Wind S Pro models I have seen all excell in this area. They are extreamly stable and penetrates the wind very well. An airplane with such good aerodynamical trim, stiff airframe and little drag just have to behave well in wind. So Hezik once again I beg to differ! Regards Anders Johansson

RE: F3A Two Meter Rule
Toss out the softmounts and you will see airframes falling apart. You will end upp with even heavier airplanes too withstand the vibrations of a YS 170. I have been involved in patternflying for more than 30 years. The noise regulations have been one off the most positive motivations in developing new and better pattern engines. Tossing that rule would be just as stupid as raising the weight limit. The best pilots will not strive for the lightest but the biggest model within the rules. It is posibble to build a very big powerful and even more expensive biplane within the two meter rule with a higher weigt limit. Anders Johansson Sweden

RE: Sebart Wind S Pro
I used the same way as Hezik to adjust the stabs though i set the wing at 0.25 degrees. When doing this I noticed that one wing had a little more positive angel than the other. This wing was changed by moving the antirotationpins. An operation that took 10 minutes. My model is flying with completly neutral elevators and enginethrust set according to the nose of the fuselage. Vertical uplines are perfect and downlines have a very slight pull to the canopy. In 30 years of F3A-competition I have never had a model without a pull to the canopy in downlines. This is indeed one of the most welldesigned F3A-models on the market. It flies extremely well. There are several new designs on this forum that are clearly inspired by the Wind S Pro. They seem to miss one of the most important features, the near midwing design. This is what gives the Wind S Pro it`s excellent knife-edge behavior. Anders johansson Sweden

RE: Monokote: back to normal or still #$%@!!!
I used Monokote to cover my Wind S Pro last spring. There was a big difference between different colours: Missile red: felt like "old" Monokote. God shrinking and easy handling overall. Cub yellow and Orange: not quite as in old days but OK. Royal blue: a bit more difficult but could be shrunk, but not very much. Jet white: very difficult to use. One had to use very low temperature to shrink, otherwise the film just bubbled and expanded. I managed by streching it in place. The rolls where purchased in sweden. Hopefully the white rolls where old stock. Anders J Sweden

Hello again! Lucky me who bought the red and white version. The all white fuselage seems to have a slightly thicker layer of paint.

RE: Wind S Pro problems
Ney! I think you are overreacting. The error was very minor. If you dont have a visible amount of aileron trim are your wings probably alwright. The error would not affect upplines as much as aileron trim If your CG is at 190mm I would call it nose heavy. The manual says 200mm at windy conditions and 210mm at calm conditions. I`ve flown the entire season with the rerward CG witout problems. CG 20mm forward would give some up elevator trim giving you problem with uplines! Regards Anders J

RE: Sebart Wind S Pro
I`m very well aware of the formerconstuction. It being in two halfs complicates the mechanics of its movement. I will not take it farther than that. I doubt that the formers are glued in at any higher preassure. The reason for the deformed fuselage sides is more likely that the formers are intalled before the fuselage is fully hardened resulting in the permanent deformation you describe. Have you also removed the carbonfibrereinforcement? Leaving this would not help the situation. I still believe that different materials and directionality thereof is the main problem. Productionquality is something that goes all the way back to the design. What more problems have you seen? Regards Anders Johansson PS The model will grow on you as you fly more. When one learns to master it it`s a formidable competition tool! DS

RE: Wind S Pro problems
Hello! On the two Wind S Pro´s I`ve built this was not a problem. With the wings mounted i rigged the airframe so that the leadingedge of the wing was 2.5mm higher than the trailingedge measured just outside the fairing. The stabs where then adjusted to zero difference between leading- and trailingdege. The stab adjusters were however near their endpoint. Engine thrust is exactly as built into the nosering. CG is at 210mm from leading edge according to manual. This gives neutral elevators and perfectly straight uplines. On one model I had to adlust the angle of the left wing, the leadingedge was to high. I simple pulled out the antirotationpins and moved them as needed. Regards Anders Johansson.

RE: Sebart Wind S Pro
I thought I`d share my experiances with the Wind S Pro after one season of practicing and competing. This summer I logged 247 flights, P11 and F11. I have competed in F3A since 1982, participated in my first WC in Holland 1985 and my latest in Poland 2003. Never before during all these years have I flown so much with so little effort. The electrics are fantastic! So on to my wiews. I`ve built two models, one for myself and one for a friend. For myself i bought a red and white version. The fuselage was sanded with 800 followed by 2000 paper. Trim coulors were applied with waterbased autopaint followed by a two component clearcoat. This gave a nice shine without any visable seams in the fuselage. The procedure added 85g of weight. The wings were releaved of their Oracover and recovered with a superior covering eg SuperMonokote. The Monokote has brighter colours and a better shine than Oracover. This also reduced the weight of the wings by 30g. While at it I did some sanding and adjusting the fit between wings, stabs and the fuselage before applying the Monokote. Equpment used: Motor: Hacker C-50 14Xl Esc: YGE 80HV Batteries: Desirepower 5000mAh 25C Servos 4*Futaba 9650 1*Futaba 9151 (Ailerons will bee uppgraded with Futaba BLS 153 for next season.) Reciever: Futaba 6008 Reciever battery: Desirepower 850 mAh with a Emcotec regulator giving 5.9V My model ended at 4820g. My friends model is a ready painted version that ended up at 4750g with the same equipment. Having built quite a lot of F3A models, mostly from plans, I have high demands on quality. The Wind S Pro meets them well. I had no issuses with building and finishing. One has to keep in mind that this is an ARF not a custom built airframe. Regarding the visible fuselage formers I`m a bit surprised by the lack of knowlage regarding materials used in model building. The fuselage is, mostly, fibreglass with a distance material and formers made of balsa reinforced with carbonfibre. Different materials expand and contract in different ways when exposed to variations in humidity and temprature. The atmosfearical conditions at the production site and the conditions here in Europe are certainly not the same. Also when using the model we subject it to big variations in weather conditions worsening the problem over time. Hezik`s model is pictured outside in the cold winter showing the fuselage former clearly. My model that was very good in this aspect when new looked almost as bad when brought in from cool storage. I built a fiberglass fuselage with perfectly made and intalled formers. The outside shape was absolutly right. At the end of the flying season the formers could be seen clearly. When talking flying proprieties the Wind S Pro shines in three areas. First knifeedge. It has no couplings whatsoever. Trim is perfect without any mixes. Rudderauthority is great. Rolling loops and knifeedgeloops are easily controlled. The reason for this is the midwing design and cleaverly designed fuselage. The landinggearfairings and pointy canopy helps keep a good airflow round the fuselage in knifeedge position, witout peculiar looking devices. A big subfin also helps here. Second is rolling manouvers. Good knifedge is one thing and the swept wing another that explains this. The third area in which the model excells is its performance in windy and turbulent conditions. Something one appricates when flying in Sweden. Here we have the narrow fuselage and thin wings that gives a sleek model with little drag compared too most F3A models. This gives good penetration in heavy winds. The airframe is also very ridgid. Built up wings and a sturdy wingtube minimzes flex. This is the reason behind the old and true saying, "Wood flies better". A ridgid airframe is less disturbed in turbulent wether and feels moore locked. Some people have written that they intend too replace the original wingtube with a PPG tube weighing half as much as the original. I would never do that. The PPG tube is much less rigid and would flex too much. That was one of the issuses with a Genesis that a flew earlier. In summary I can only say that this is the easiest model I have ever flown. It is predictable and honest and feels extremely stable and loocked. Regards, Anders Johansson Sweden

RE: Sebart Wind S Pro
If you by delicate mean fragile the answer is no. The fuselage is vacuumbagged in the molds with divinycell (I think) between the layers of fibreglass. It is sensibly reinforced with carbonfibre in the nose section. All hardpoints for wing, stab and gear mounting feels solid without being overly heavy. All in all the fuselage is light and stiff. The wings are built up balsa wich means that care has to be taken when carrying the model. Flightloads is definatly not an issue as they are very stiff. The wingtube is also very strong and stiff, also quite heavy. I would not replace it with a lighter one though. The reason for that is that I want the stiffnes the original tube gives. With a total weight of 4800g with 5000mAh batteries weightreduction is simply not needed nor desired. Qualitywise it is not an Oxaimodel but it is more than good enough. As for flightperformance I think it is one of the best. Anders Johansson Sweden

I have flown my Wind S Pro about 80 flights. It has the same setup as Anders Forsbergs model except batteries. I run Desire-power 5000mAh. This is my 30-th year in pattern competition. (I flew my first WC in 1985 and latest in 2003) In these years i have never flown a model as honest and easy as to fly as the Wind S Pro. It tracks well and has a locked feel to it. Knife edge is outstanding. I fly with no mixing. Rudderauthority is very good. The figure M in P11 is not an issue with this model. Rolls are very easy to perform. It also snaps and spins well. Stall turns are calm and predictable. I realy try to find flaws in flight caracteristics but havent found any yet. The thin wings and narrow fuselage gives the model good penetration in windy conditions. Low drag also helps keep power consumtion down. Yes I really like this model! Anders Johansson Sweden

RE: Stabilizer halves of different incidence? What gives?
Different incidence on the elevator halfs influence the knifedgetrim. The elevator half pointing up in knifeedge is partialy blanked by the fuselage. Therfore the lower elevatorhalf controls the tracking. This results in different trim in right ond left knifeedge position when the incidence differ. In the old days, before computerradios allowed the luxury of electronic mixing, this was used to trim an aircraft that tracked differntely in left and right knifeedge. If the stab was`nt adjustable the elevatorhalfs neutrals were slightly separated. This proved very sensitive. On my Joker i wished it was possible to adjust the linkage 1/4 of a turn.
