Anybody interested in a NEW YS shortstroke? New, as in produced this year...
 

Hi Guys,
I have some potentially very exciting news: YS is considering manufacturing a new 10cc (.61) rear exhaust short-stroke engine.
This really got started by Chip Hyde when he opened the post regarding which 3 classic pattern kits would you be interested in. Of course, the concern was raised regarding availability of rear exhaust engines. I knew Paul Pappas had called Rich Verano about a year ago to inquire about YS making more 60s and there didn't seem to be much interest by YS at the time. I decided to give it another try and spoke to Rich about the possibility of YS producing some more 60s about a month ago. Long story made short(er): we chatted, he chatted with YS and they are interested in the project!
I don't have much information, yet, but I do know the following:
This will be a new version of the short stroke; YS wants to use the long stroke case (apparently they can't make the 'FR' case anymore) and update the design to make it a short stroke engine. I don't have specifics, but essentially this would entail boring out the case; new, larger diameter piston, shorter connecting rod, different crankshaft or just different placement of the crankpin and some porting and timing changes. Knowing YS it will undoubtedly have more power than the original 'FR' and the design philosophy seems to be addressing the needs of the CPA pilots looking for peak power at higher rpm. If the torque curve of this new engine approximates that of the old 'FR' it will be quite flat, producing excellent power at a surprisingly wide rpm range.
I have included some photos of an original .60FR (on the left) and a newer .61LS to whet your appetite.
The only other information I have is that YS is hoping for a mid to late summer 2012 delivery date.
Currently, they are considering making 100 of these new engines.
Is there enough interest to purchase 100 (or more) of these engines? I know I'll be good for a couple - at least!:D
Regards,
Will Bartlett
PS - I have no 'personal' interest or stake in this venture (unlike the Hanno sleeves) - just a very excited spectator!

This is cool! I think 100 engines would last about 5 minutes! :D

Interested?? Yes, but it sure would be great if YS made something that used parts compatible with the old 60 FR. I bet there are hundreds of the FRs around that need piston/liner sets or rods, wristpins or some small parts..........

Is there any indication as to approximately what the price would be for this run of 100 engines?

Best regards,

George

Yes, I am interested but agree with George. Probably would buy 2 of them though if the price was right.

interested here too

RE: Anybody interested in a NEW YS shortstroke? New, as in produced this year...
 

if they use the long stroke modern case it may make for a better engine anyway, having a longer rod with the short stroke makes for better torque and less side loading on the piston as well, which in turn means less wear on sleeve and piston

i will take two of them plus spares

+1

interested price dependent...not paying 500 for a .60, ever.

RE: Anybody interested in a NEW YS shortstroke? New, as in produced this year...
 

So Will, are you trully saying that YS will only sell the new motors in a lot of 100, not individually? - Steve</p>

RE: Anybody interested in a NEW YS shortstroke? New, as in produced this year...
 

I doubt that. I think what Will is saying is that they are doing an initial run of 100 units to be distributed by YS USA and possibly others.

Why not keep it long stroke and get that prop flexibility and torque?

RE: Anybody interested in a NEW YS shortstroke? New, as in produced this year...
 

Very interested. Would love to know the price point. Cool Stuff for sure!

id be interested and would pay no more than 300... if not ill stick to my old reliable FSRs or hunt ebay for an OPS or Rossi 60

RE: Anybody interested in a NEW YS shortstroke? New, as in produced this year...
 

Yes. 2X.

Can I pre-pay? :D:D:D

RE: Anybody interested in a NEW YS shortstroke? New, as in produced this year...
 

I'm good for one.

Hi guys,
Great response! I will answer questions as best I can. YS wants to make a run of 100 engines which the US importer (Rich Verano) will purchase. The engines will then be made available to the public (I do not know the specifics) for sale. You (the modeling public) can buy 1 or more engines at a time until they are gone. If this is successful (I don't know how that will be determined, but for the sake of argument let's say all the engines are sold within 6 months of release) then YS may consider making more.
Price...? I can't provide any hard numbers, but I can say that the price will not be near $500 and hopefully closer to $300. Remember, this is just at the discussion stage. I threw the $300 figure out when I talked to Rich just as a consideration. My logic is that $300 is probably about what most guys interested in CPA aircraft would be willing to spend, much beyond that and you start approaching the price for a Jett 90 FIRE which are basically custom built. I think the AXE Rossi rear exhaust was about $300 (approximately) when it was available.
One last point, I am doing the 'research' for Rich on the interest level for this engine; so the more honest interest/feedback I get, the better I can assess the market for him.
Thanks,
Will
