I purchased that YAK 55" from Nitro and it is a fun flying plane. 3D's OK with an OS 70FL. I was surprised at the quality of the arf. The manual was terrible though. But for the price...

I bought a few of the cheap arf's to build up the hangar and now I know what I like and am starting to get some of the higher end stuff. I was real tempted by the Nitro 50cc and the 50cc engine from united hobbies. Plane and engine for less than $600. Can't beat that with a stick.
