Default 1.20 for a Venus 2?

Hi, I'm a total noob to pattern flying and I was looking at getting a Venus 2. I see that it takes a 1.20. Any recommendations?

Thanks in advance!

I used the OS 1.20 4-stroke and have been very happy with it.

This message link is in a somewhat long-ish thread with lots of other info re Venus II.

Mine also has an OS 120 FS, great engine. I flew one 2 weeks ago with a YS 110 - all I can say is WOW. I just traded a Saito 125 I had for a YS 110

Sorry Bob but I MAY be a convert

I'm thinking that those of you who like 2 - strokes may like the OS 120. But it may not run like a 4 - stroke inverted.

Good luck, Don. I am considering one of those myself, but am content to wait until you get it all figured out.

Particularly interested to see how you route the exhaust and whether the YS is a lot more finicky than the OS, as they are reputed to be. A lot more gizmology going on there!

The OS 1.20 is the way to go.

This is what I did with my YS110.

Sorry Bob but it will be awhile, maybe even next summer. I plan to fully invert the YS, use a flex header and mini pipe. The one at our field is fully inverted with the muffler out through the side of the cowl, looks good.

I already have 3 YS engines so I know all the pitfalls. But like any high performance engine you learn to deal with it for the rush of power

I have the 120 2-stroke in my Venus and it does all I could ask. Had to put the battery way aft to get it to balance, though.

I have a stock OS 1.20AX mounted inverted in an Explorer 90. 100 FLIGHTS NO PROBLEMS. Runs great - loads of power with a 15x10APC. 13 oz tank good for about 9 minutes. Good throttle response, too.

Interesting. What RPMs do you get with 15X10 on the OS 1.20AX?

I have no idea what the RPMs are (I haven't bothered to tach an engine in decades). I just want reliable power which the 1.20 AX has provided very nicely. The muffler works very well as the engine is surprisingly quiet. I have not had any problems with the 2 piece AX 'power box' muffler, but I did loctite the nut that holds it together. The muffler has a rubber 'O' ring between the front and back halves which does seep a little exhaust, but may aid in keeping it together.
I will guess the rpms are between 8500-9200. I haven't bought a new OS engine (side exhaust/sport type) since the SF series and I must say I have been very impressed with the 1.20AX (enough to buy a second one).
