Well I tried the YS 1.10 on my Mojo 60 and all I can say is HOOOOOOOLY COW!

It works really well and you have the most stunning vertical performance I have ever seen from anything without a solid fuel cell. [8D]

The plane actually handles the weight of the 1.10 incredibly well from a wingloading/handling point of view.
However, I know that Paul (Swanson, designer) does not recommend the 1.10 on this plane and I can see why. It is absolutely totally and completely insane power and if you are not smart with it you are going to break the plane. This plane with this engine is a good combo IF IF IF you are very responsible with the throttle. If you get on it in anything but vertical flight you are going to probably tear up the plane. I found that if I just keep the throttle on a leash and use it only as needed and no more this is a really cool combo that delivers really great performance. I put entire gallon through it today and I had a blast.

does it look like the plane was kicked in the butt on up lines?[8D][8D][8D][8D]

It was so fast in vertical that I had to back off for fear of flutter, no kidding. It literally looks like it was shot out of a gun, it climbs so fast you won't believe it.

My point in making the post is that from a weight and performance standpoint its a great engine to use, its definitely not too heavy. But it is literally a rocket so you have to stay off the throttle unless you are going straight up and even then you have to be smart. It handles normally in 3D flight and you can do most of your stuff at 1/4-1/2 throttle. It landed with the engine ticking over very slowly and slowed down nicely for some pretty harrier landings.

Something else. This plane is even tougher than I realized. Today while I was working on tuning the engine died on me several times and the plane just fell to the ground as far as 10-12 feet. Each time it just bounced on the landing gear and sat quietly. No damage. This is the toughest airframe I have ever seen. [8D]

good deal i know what u mean in your throttle mgmt its still kewl to see a bird go out of sight lol

That's nothing.. mine went straight in from over 100 feet when my Saito 100 caused a battery wire to fracture on a vertical downline.

It went in vertical, buried the engine so deep that all you could see was the occasional glint from the intake manifold.

Total damage:

The battery went through the front of the wing and took a bit of sheeting out.

Two bent pushrods and tubes on the Saito.

That's it!

It took 20 minutes to repair it well enough that you could never tell it had been smashed and it still flies today!

Tough just isn't the word!

wow

Mike i have the 1.10 on my moass 60 also. i put it in because i needed the nose weight,had a new saito 1.00 for it but was to light.it's nice to have a plane that will jump tall buildings at a single bound out of a hover,when your dragging the tail.this is still one of my most flown planes.

I salute your and your rocket ship!

Mine is truly great with a Saito 100. You've got the equivalent of a 150 on there-- but with better throttle response I bet.

Isn't it great with these birds how you can just say, "Hmm, I've got this big motor sitting here, and it won't take much to bolt it onto this lightweight airplane... I wonder what would happen?"

I can relate to it - I took the Saito 100 off mine and fitted a Saito 125 for a bit of fun - It was GREAT with the 100 - It is FANTASTIC with the 125. Any plane of mine that lasts for more than a year just has to be considered super tough - especially as between myself and the two teenagers - it is our most flown plane.
