Care dintre cele doua marci de motoare ar fi cel mai bun pt. un elicopter clasa 90?
Se stie ca O.S.-urile sunt f. bune, dar imi spunea cineva ca Yamada ar fi "the best".
Ce parere aveti?

Adi,
Uite ce spun cei de la heliproz :
BIG GUNS  The YS .80 and the OS .91 SXH-WC
HeliProz was among the first to have these engines and we have run a lot of fuel through both. (We have also sold more than any other dealers and have a lot of customer feedback). Let's just say these are SUPER engines!
The YS 80 is identical in mounting dimensions and identical in operation to the YS .61 ST2. Again, it is simple to adjust and VERY smooth and consistent. It has a definite power boost over the YS .61  not just a little either! Idle and transition are excellent. Yamada's instructions recommend a gear ratio of 7.0 to 7.5 which is very strange  unless you run a 2200 rpm head speed (which will destroy most current helis!) you will find that an 8.0 to 8.4 ratio will put the engine in it's peak torque range. YS 61 mufflers will NOT work on the 80, as it has much higher exhaust volume and needs more expansion area. The KSJ 80 muffler is our favorite. We've run the YS 80 in our Vigors with both the standard 9.3 ratio and with the 8.4 ratio. Even with the 9.3 it ran fine and had tons of power. But you must keep head speed down to avoid over-revving, which of course slows control response. With the optional 8.4 ratio the engine is obviously happier and more responsive. Again, it's about $10-$20 more expensive than the OS .91 but you YS fans will be extremely happy with the power boost.
AND THE WINNER and STILL CHAMPION.
The OS .91 SXH is our pick for engine of the year and then some. Free from the old FAI 10cc displacement limit, OS tossed the 3-needle carb and (overly?) aggressive porting and gives us more power the old-fashioned American way  50% more cubic inches!! The results are stunning. This engine drops right in to any heli that the OS 60 fits. The 2-needle carb is similar in looks and design to that on the OS .50 SXH and is equally spectacular in operation. Set it rich and fly all year! This is one cool-runnning, smooth operator and it puts out obscene amounts of power! Your old 60 muffler will NOT work, use the new KSJ 90 muffler or the new high volume Hatoris. You may also need to upgrade to a 24 volt Dynatron starter as the ringed engine is very tight and stays that way. But the upgrades are definitely worth it! We have many cases through the OS .91SXH and it's the best heli engine we've ever seen. The power output is WAY beyond the hottest 60 you have seen, and the power is SMOOTH. Idle and transition are excellent. With the standard ratio in our Vigor the engine seemed very happy and power was exceptional. Then we put the 8.4 gears in and HOLY COW! What a Monster! Running slightly rich (and ridiculously cool, CHT measured at 195 degrees F after an entire tank of flipping  on a 94 degree day!) the power and acceleration were the best we've flown. The only thing even close is the YS 80.
Speaking of cool, one of the Grey Market Japanese vendors keeps trying to convince us that the engine runs hot and so you need some "special" aftermarket cooling head. Of course you have NO WARRANTY in this country when you buy grey market so there's no point worrying about your warranty being voided, but it is NOT needed! At this point (End of 2001) we have sold more OS .91s and run more fuel through OS .91s than ALL OTHER US DEALERS COMBINED and we have had NO cooling issues at all. NONE. And we haven't had a SINGLE CUSTOMER experience any cooling problems either. No doubt some enterprising US dealer will come out with an aftermarket cooling head but we strongly advise against voiding your EXCELLENT warranty by installing one. If you are having cooling problems we'd like to hear about it.
NOTE  as with all OS engines we are not allowed to show our actual selling price  so you have to call or e-mail us to find out our actual selling price. WE ARE THE BEST SOURCE FOR ALL OS ENGINES  Best Pricing, Best Service, and Best Support!

Mersi frumos, dar... Eu la scoala am fost unul dintre baietii rai, nu prea mi-a placut cartea. Asa ca nici lb. engleza (alta nici atat) n-am invatat-o cand a trebuit http://www.rhcforum....tyle_emoticons/default/sad.gif . In mare parte ma descurc dar textul tau este prea mare.
P.S. Exista vre-un programel ceva de tradus?

He,he,he, sunt prog de tradus dar o cam dau in bara.
Ideea este ca face o mare comparatie inte OS si YS de care spuneai tu.
Practic se refera la upgrade-ul de la 60 la 90
Ambele motoare se potrivesc ok.
La ambele motoare trebuie schimbata teava de esapament cu una corespunzatoare de capacitate mai mare.
La YS producatorul da un raport de 7-7.5 care aduce heli la 2200rmp. Acest lucru distruge marea majoritate a heli-urilor actuale.
Virful de putere il are la un raport de 8-8.4.
Ei au facut test pe un heli Vigor cu raport 9.3 si tot avea putere girla.
Trebuie tinuta turatia jos altfel incepe sa raspunda incet.
La OS sunt tone de superlative.
Au testat tot pe Vigor cu rap. 8.4.
Considera ca puterea si acceleratia au fost cele mai bune cu care au zburat.
Mai spun ca singurul motor care se apropie !!!atentie!!! este YS.
Oricum dupa ei cistigatorul este clar OS-ul
Cam asta este rezumatul.
Sa cresti mare si sa fi baiat cuminte ! http://www.rhcforum....tyle_emoticons/default/smile.gif
PS: Spune-mi si mie ce upgrade faci. Asta ca sa nu mor de curiozitate ca cine-ti mai face rezumate : http://www.rhcforum....tyle_emoticons/default/biggrin.gif

In primul rand mersi de amabilitate.
Nu este vorba de un upgrade, doar incep sa ma informez din timp in legatura cu urmatorul heli pe care intentionez sa-l iau http://www.rhcforum....tyle_emoticons/default/rolleyes.gif.
Elicopterul vine fara motor si ca atare ma gandesc sa ma orientez la asta, sau la asta.

@Ady13
Felicitari pentru gusturi. De ceva timp ma tot uitam la unu' ... dar inca ma mai chinui cu Ornith-ul...
Cred ca OS e varianta sigura chit ca Yamada se spune ca este super puternic. Despre OS pot sa-ti spun ca face ceea ce scrie pe cutie!

Bafta multa Ady !
Anul trecut era cit pe aici sa pun mina pe un Raptor60. Si unde mai pui ca era si carosat !
Dar...nu a fost sa fie.
Cred ca o sa scot la vinzare 30-ul si...
Ce spune Down este tare adevarat !
Din ce am citit si OS are multaaaaa putere dar, spre desebire de YS, este SIGUR.
Din experienta mea OS-urile nu m-au dezamagit.
Pentru un pic de putere in plus fata de siguranta data de o lunga experienta...eu as alege OS-ul !
Bafta
