I received the next generation Spot-On from World Models a few weeks before my trip to Hong Kong, and started working on the plane right a way. Originally, I was planning on finishing the plane in two weeks time for a test flight. Unfortunately, due to my busy practice schedule, I couldn't get it done before my departure. Since this is an evolution of the first generation Spot-On, I wasn't planning on a complete build thread. For that, you can check out my previous post, and should you have any question, feel free to contact me.
Although, the model is still under the name Spot-On 120. Realistically, this is actually their "R" version - Revised. Externally, you will not be able to tell much difference. However, if you look closer, you could tell it is slightly smaller than the last one. The fuse and wing span is 40 mm & 20 mm shorter respectively, and the wing area is 0.4 sq dm smaller. The major advantage is you are now able to use a YS 110 with enough power to spare even for the vertical maneuvers. Another reason was, I have expressed to Fai Chan - my good friend and one of the owner of World/ Airborne Models - the lack of suitable engine choice for the original design. If you want to be competitive, you have to find either an older YS 120 size engine, or, use an OS 120 AX. If you use one of the new YS 140 Sport, or, 140L in my case, you will ended up nose heavy. Besides, in Japan, they have a special pattern class dedicated to 110 size plane, and the older 120 was just over the size limit.
Besides a small size reduction, World has also incorporated a few of my suggestions which include the following:-
1) A smaller soft mount to save weight
2) A round shape bottom chin cowl to accommodate the Hatori header and short pipe
3) Fuel tank has been relocate to the cg area, rather than right behind the firewall
4) A one piece wooden push rod for the elevator control
Unfortunately, they are still using the same heavy tail wheel assembly. The same stab adjuster unit, which could stripped very easily with one false move. In addition, the sharp edges on the iron on decoration will still peel easily. Other than that, not much else to complain about. At this point, Fai has not quite work out the pricing yet, but indicated most likely will be the same as the last one. I was really happy with the way the last one turn out, and was more than anxious to get my hands on this one for a test flight.
