New/used wedico 345

[Riley XX-L]

So been lookin for a good excavator for awhile and run across a wedico 345 like new but used and must say very scale and nice quality but it’s different than I am use to like the magom and rc4wd/jd models. first is how hard is it to find capiable parts for upgrades as I noticed wedico is still on a mfu board style esc? I am not a lights and sounds guy and was thinking new radio and 4 esc’s and upgrade the track drive motors and pump motor but have no idea on the kv rating needed as wedico is still on brushed and would like to go brushless pump motor and tracks just need more power. Help is needed. Thanks guys
