If and when OS (or YS) releases or first shows a bona fide big block/case 1.2 ci engine, you can pretty well bet it will take Align and others about 2 weeks to redo the clutch, mount, and fan as needed to accomodate. Most models out there today are configured in such a way that the wider footprint of the engine would be no problem with nothing more than a new mount. Any need for a bigger clutch can be handled with a little more diameter and/or thickness. A new fan isn't that big a challenge either. I really do "get" the idea in trying to further bore out the .61 case for a plug and play installation with nothing more than a gearing change needed, but at some point the limits of the current crankcase and rear bearing have to be met. In the process of testing, that which Tim and other test pilots can get to work OK is not necessarily the same as having something that is forgiving enough for a guy who lives in the desert SW (HOT) AND who can't tune a one string guitar. After the pros are initially satisfied, the next step is to make sure Joe Public can play well with a product. Often this is where feet really hit pavement.

That is very true. Until Bubba gets to tweakin' on one and it stand up... then you've done something.

Might just be your area but all the fuel prices in and around my state are about $25.

The fuel distributors don't set the retail prices, the shops do. if the prices get higher talk to the shop.

Prices here have stayed at $25 a gallon for the past 2-3 years so it's obviously where you and others may live that determine the prices.

I can tell you that the fuel I run is Byron, there is certainly no lull in sales and I can guarantee that every gallon they bring to IRCHA will be gone come Sunday.

I talked with Tod Bennett at the Snohomish FF this weekend about the YS120. He said...
Well here's an excerpt from Todd's site posted TODAY:

"I was up in Seattle Washington last week for a fun fly and there were lots of questions with respect to the release of the new YS 120. I have been testing this engine for a long time now and working on many versions of mufflers with Tetsuo Hatori from Japan.

We went through a lot of work getting the muffler right for the new YS. All the test pilots that received the latest muffler for testing have been happy with it. I was not sure of the release date of this new engine but I was told from YS today, 8-2-11 that it is coming out soon. Please check the YS websites for the release date of this engine; I am sure they will be posting it when they have solid shipping dates.

Todd Bennett"

Todd,I started this post and have followed it from the start and a lot of the 120 vidieos ,a page back on guy mentioned that you were concerned about an overheating problem,I.m in Dallas where we have been experiencing 100 degree day straight for the past 30 plus days,today it was 110. Are you still concerned about it running hot?

Interesting

I looked at the post from Todd's site and all I can say is I stand by what I heard. The comments I posted about the difficulties of building a 120 motor in a 60 size case are all still valid. Maybe it will work just fine. Let's hope so. steve

120's

I don't envy them with the 1.20's size motors, I tried an airplane OS 1.20 a few years back in one of my Avants. The balance was not even close for helicopter work and the vibration sprinkled parts around the field as you flew. The torque for FAI F3C styles was very nice with a low engine speed, but in the end it needed more research than I was willing to put into it.
