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.
