Also some other small things to note as well for the 511.. is that you can use a lot of the 503 parts... hopper bulkheads shock towers gear diffs front alloy hinge pin brace and a few other things so you can use the new front kick up.. I believe that you can also use 1/3 of the motor mount as well
Parts support in the States.. is well.. OK.... not the best but they have them... but prices are stupid and expensive
.. I go back to my other home in Japan twice a year and get all of my parts then... pretty much stock up
since I can get about 2/3's of the parts at over 50% off of what I would pay in the States
