10 cc

They will pull up to a 13 X 6 prop

You can run as small as a 12 X 6

They are a decent 61 four stroke

The OS FS 61 manual is not on that page?

You will have to call hobby services at Tower and ask for they may be able to mail you a Zerox copy of the manual?

Just send them an email requesting the manual if it's not listed. I sent in a request a couple weeks ago and got a PDF within a half hour.

I have one. It's not as powerful as newer designs, but it is durable and reliable. Mine was finicky about idling until I added an onboard glow driver. Now it's great and trasitions well.
