I recently became the owner of this almost new 3W-120 (rear carb style) and it needs a home. Would it be powerful enough to haul around a 3.0 extra 330L without being grossly underpowered. Obviously, I would not expect it to hover at half throttle or do the things that a 150 powered ship would do. If it would be capable of the basic and sportsman routine, I would be happy.
Do you think this engine would be up to this task or am I out of my tree for even considering such a thing?

You should be fine, keep the batteries, etc nice and light. You should be able to swing a 30X10 with that motor. And put either canisters or tuned pipes on it, that will help. I just bought a Super Extra for my 3W 200, that ought to get er done!!!

When the 120s were being used by all the TOC guys they were all running 28X10 props. This was before the current group of 140s and 150s were in production. The DA 100 and the 3W 106 after some break-in time will swing some 28X10 props as well. Bottom line is that you have a 120 that is just a tad more power than the current crop of 100s. I would suggest that if you really want a Comp ARF go with the 2.6M Yak. The 120 should fit in the cowl and power will be about right. I really think you would be disappointed with a 3M with a 120 under the hood. I have flown a 3M with a DA 150 setup with the Dalton CF pipes. Prop was a Mej 28X12 3 blade. Power was just right for the advanced sequence.

I was looking at the 2.6m yak. Only problem is this engine is the exact size and weight of the 150 so it may not fit into a airframe designed for 80-100cc. Cutting holes for the plug caps is something I could live with, but nose heavy or overly high wing loading is not what I want in a plane. If I had to make a choice, I would much prefer and enjoy a plane that flies light but is a little down on power.

I sure would like to hear from someone who has this engine on a Yak.

what about the TOC 35% yak? I hear great things about them and they are a very large 35% airplane, and the 120 would be perfect as they are coming out 28-30lbs, and bigger than the comp arf yak, just a thought.

There's a great idea. I still think you would be able to ballance the 2.6 Yak knowing that it was going to be nose heavy. The 3M Extra would be a good sport model with the 120 but I doubt it would be competitive past Sportsman. When this engine was in vouge the airplanes it was hauling around spanned around 115" and weighed no more than 32 lbs. The sequences weren't quite so power hungry. IMO flying a really nice airplane with limited power just makes you miss the power even more. Kinda like driving a new Porshe but with only 100hp.

Check the cap 580 from great planes too.

You might consider the Composite ARF Giles. This plane comes in lighter than the 3 meter (low 30's?) and I have been told that for sequence flying it is very strong. You might also try to find one of the 37 pct Extras that Aeroworks used to make- they can be found here and there.

I personally believe that you can fly a "bigger" plane with your 120. Remember that the TOC flyers were using them on planes that weren't much smaller than current 40pct planes not too long ago.
