Jen,
Some things I really liked:
• Gear reduction in the car body, as opposed to being located in the
superstructure. A nice solution to the backlash problem with the tranmission
parts.
• Use of transmission parts to create the concentric drive shafts through the
turntable. (a most excellent approach ;-)
• Anti-rotation guides for the doubled cylinders. I experienced this problem
with my R996. (Fortunately, I had doubled sets on each segment of the boom, and
I simply tied them together laterally with an axle.) But your guides solve the
problem and it looks great.
• Overall shape and appearance of the body is excellent. The curves, the snot,
the colors- most excellent.
• Back to back connection of cylinders- very clever. I had to try this for
myself. It appears the cylinder bottoms can slide a little, but only with
significant force. I conclude that the connection is tight enough to keep
anything from slipping during normal operation.
I thought at first glance that this model is a little less impressive than your
AC-50. The AC-50 is larger, has more features, and is probably the best crane
MOC ever built. However, after thoroughly reading your webpage and seeing the
features and images of the JS-220, I think perhaps it's your best model yet.
It is small, but highly refined and well designed. All the necessary features
are present, and they operate well. It seems you sacrificed very little in
appearance to gain the required functions of the model. Building such realistic
MOCs are always a fine balance between function and appearance. You've achieved
both with the JS-220 and quite well.
Well done! The only comment I have is that you kept us in suspense for too long
with the release of your webpage! :-)
best,
TJ
