As rule of thumb, I usually tend to avoid publishing here at the weekly TechVideo post, any videos which are already presented at EB, or some other Technic related websites.
But as every rule has its exception, occasionally this also gets one...
VMLN8 from New Zeland made a motorized stingray. All the fascination goes with the simulated undulating movement of the wings (see it on the video below).
All the propulsion is provided by the stingray (no hidden propellers). Power and flotation devices goes on the top (at surface).
You can find additional photos from this model, at VMLN8's flickr gallery.
Please avoid sending requests to post specific models on this TBs section.
We understand some of you would enjoy to see your creations featured here, but please understand that because only one video gets highlighted per week, it is impossible to accommodate all the great MOCs continuously build by the Technic builders out there. They simply won't fit all and that's also not the purpose of this blog (see the header statement).
Many of your MOCs are scanned anyway and listed for later publication when they do not fit immediately. However some remain in the backlog queue just for too long and eventually loose the relevance or the publication opportunity window. As a rule of thumb, we also avoid publishing MOCs that have been featured by their authors or other fans at some other great web places dedicated to the Technic community out there. It doesn't mean that occasionally some won't get published here anyway.
Thanks for your understanding!
