Thanks for the positive comments! I too think there are far too many motorized vehicles used as model ideas for Technic - Lego themselves are pretty bad at releasing only vehicles year after year - so I do try to be a bit different.
I second that "what the?...." But whatever follows is something really positive. I think this is brilliant. It is so much different than all the model-type vehicles that are out there (guilty am I b/c thats all I have out there as well) --- great job!!
