Will the STRC ESC mount fit the Traxxas LCG?
Are there any other options that fit directly?
Yes it will! There are a great many ways to mount the esc. I used a servo arm to hold mine down.
Slash Ultimate El Sob special MIP King Headz 3PL
Rpm makes an "esc cage" for the vxl-3s
strc plate with 3m duallock holding the controller to the plate. i've never had it fail.
El sob has a good idea. I don't know what esc you have but I did see a mounting system from snappy rc. I think it mounts the mamba max pro in the stock esc position on a slash 4x4 but not quite sure on that
