ORIGINAL: On The Patch!

Hello all!

I have a Saito 1.20 that I bought about 10 years ago, was sitting in the box for about 9 years and ran it for the first time about 10 months ago. Since then it has had about 1 gallon with 10% nitro through it. Running pretty well with an APC 16x6. Borrowed a tacho (tower hobbies) from a friend but readings were fluctuating A LOT, so I don't really trust them...

1. Does anyone know what RPM I should expect on this with the APC 16x6 on 10% nitro? People are reporting around 9k with a 16x6 on the 1.25, from what I've seen.
2. How does this engine compare to the new 1.25? I know mine is heavier (960g, ~34oz, incl muffler), but I am not sure how it differs in terms of valve-sizes and other stuff..

Any help would be much appreciated!

Sincerely

Johan
