hi, a lot of info from this thread... am only at pg28.

can hacker BL motor fit into the E4 without mod?

anyone tried to custom order the E4 RS with a one-way instead of spool? i know Wolf hobbies is able to customize E4 orders in the US but I am ordering outside of US. And nope, ordering from US is wayyy too expensive in terms of shipping.

perhaps TM can include the 'multi-diff' in the E4RS just like what they have in the original E4...
