We do use MOSFETS for 180 builds . Fuses are fairly impractical , as the blade type only go up to about 50 A and take up a lot of space . If your fuse is correctly rated it won ' t blow in normal use , it will pop under full stall or short circuit , as it should . Yes MOSFETS are safer because they take the current load away from the grip , but they are not a must have for 130 ' s , I wire all my commission Stryfes with them because if the user wants to upgrade they can keep the loom and just swap the motor block . They can be used on the flywheels of rapidstrikes as well , but it ' s more complicated and there ' s less space . We have a wiring diagram on Britnerf if anyone needs it . <| sep |> I bet this is a case of ' it works , DONT TOUCH ANYTHING '
