either it is typed wrong or theystuffed 60's in this 600. What are we going back to 60 size helis again. Most of us old timers went from 30,s to 46's then 60 then 70's then 80's then 90's back to 50's
now 60's AGAIN. Whats next 650 blades then 680 to 690 then again to 700 blades looks like a circle I have been through before!!!

I know that a YS 60 lying around looked tempting fitting in it but I don't what to go in that circle again!

I wouldn't say no to a 60 in my 600. You can get aero engines that are almost 60 capacity in a 50 case, why not heli engines? It would be great

The typo is on the ircha video page. They are 600N's.

I also noticed the "60" reference to the Krause & Szabo IRCHA videos... I believe there is potential in a bigger bore and longer stroke in a 50 engine. I should know... I have a Jett 60L (aero engine) in a Sceadu.

It has nearly the same bore/stroke dims as the OS61SX-H but it is in a 50 case size (and weighs about the same as a typical 50).

With the Jett, the potential is there, but right now it is hampered by the carb. As with just about any carb designed for a prop turning application, the mixture is too lean in the midrange. I've modified the carb to meter more fuel in the mid, but still have to run the low end needle so rich it wont idle.

On top of the carb issue, the front bearing is 10mm ID (opposed to .375" ). I had to modify the fan hub so it would fit on the end of the crank. Furthermore, I had to fashion a heat sink from an old Pentium II CPU.

Proofread carefully to see if you any words out.
