The tweeners are the FA-100 and FA-125.
FA-65-FA-115 fits the same footprint as a .60 2-stroke, the FA-120s FA-180 fits a .90 2-stroke footprint. The FA-100-FA125 are the misssfits.
The FA-100 makes less power than the FA-115 and the FA-125 does not significantly out perform the FA-115. FA-115 has the same bore and valves as the 125 and better volumetric efficiency.

So what was the purpose of the 115?
OF, you got to give me a while, I got to review my head and think what to say/type first

My wife examined my head once and walked away shaking her's. I told her I wanted this Tee shirt for Christmas and she shook her head again.

Applying a little logic the 125 makes more sense, to me anyway.
Saito 125 turns a 16x6 at 9,000 rpm costs $374.99
Saito 115 turns a 15x6 at 8,800 rpm costs $369.99
That's way more than $5.00 worth of additional performance, I bought my 125 from Horizon during $30.00 off sale and free shipping.

William,
I think you can help me with a Saito 82 that I took apart to release a sticking Tappet valve. The problem is that I forgot exactly how to the Cam Gear is to be positioned in relation to the compression position of the Piston. I hope that makes sense and you can help me out. I did get it together at one point but while I regained engine compression after freeing up the sticking Tappet, the engine refused to create suction to sufficient to bring fuel into the carburetor.
Thanks in advance,
Sheldon

William,
You may have received an earlier message from me from a previous account but please respond to this message with a new email address.
I think you can help me with a Saito 82 that I took apart to free up a sticky Tappet. My problem is that I don't recall how the Cam Gear is to be positioned in relationship to the Piston position. Should the Piston be in the compression (down) position or in the intake (up) position in relation to the Cam Gear position? I did have it put together but the engine wouldn't suck in fuel. I even tried priming the carburetor but the engine still wouldn't start. Hope you can help! It's a newer engine with only about 4 flights on it so I'd like to get it working.
Thanks,
Sheldon

Dave, I would love to have a Saito 100 to hop-up, but I don't need to have 14 planes LOL
not that I have 13 planes because I don't, I just I don't need 14 engines, if I did I would want more planes,,, it a head twister

Welcome to the wonderful world of RC! Having more engines than planes is a good thing. Helps you plan for the future! 
My problem is I buy engines then have to figure out what plane to use them in, then find out the plane I really want to use them in, doesn't come in a size made for them! I would like a WING B-25 as they are the right size for the pair of 91 FS I have.
Can never have enough Saito. Still kicking myself for not buying that 300 T when I had a chance, brand new in box $300.

Jim, here is an early version 1.25 with a missing exhaust pipe. Not a bad price, it wears the jug on the left with the shallower and fewer cooling fins.
Saito FA-125 - RTF (ID: 1124924)
The pipe is 20 bucks, Horizon's shipping is very reasonable. https://www.horizonhobby.com/muffler...--bn-sai125a75
I am being helpful ain't I.
