Default Magnum 120 4-stroke or Saito 100 in a Seagull Yak?

Which would you guys prefer, a magnum 120 4-stroke, or a Saito 100, in the 90 size Seagull Yak? I imagine the Magnum is heavier, but will it produce enough of an increase in power to justify putting it in my Seagull Yak. Currently there is a Saito 100 in the Yak. I'm pretty familiar with the Saitos, but not so much with the Magnums. I got a good deal on a used Magnum 120, and I'm looking for a home for it. I'd appreciate any advice you guys might have.

I have an ASP 120{same as a Magnum }, I used it in a Seagul Extra 260 and edge 540, both the 90 size . Moved the battery around to get the proper CG on both of them, so no extra weight.The Saito 1.00 well fly itOK and had one in the Edge fora while,And it did a nice job, but the 120 does it just a tad better.
Paid a $100.00 at a swap meet , used and it's one of the best runners I own. The Yak is nice looking plane , Enjoy

They produce about the same power in the real world and the Saito is a bunch lighter. Bench run the Magnum before you stick in in any plane to make sure it runs well. A lot of people like the Magnums, I'm not a big fan so I sell or trade them whenever I get one in a trade deal.

Thanks. I'll take your advice and bench run it first.

If your budget will not allow the purchase of a new motor I would say the 100 Saito because it will be a ton lighter the them 120 mag, but if it was me Id put a 150 or 180 in it, An fg 30 or 36 would work too.

I can afford to buy a new engine, but some of my best/favorite planes and engines were bought used. Swapmeets are my favorite places to go

OS 1.10 or maybe a YS 1.10

If I actually had your two choices on hand though, I would probably go with the Saito 1.00

The Saito is on the plane right now....I think maybe I'll leave it there.....maybe find something different for the Magnum
