Hey lambchops, yes, that is a nice solution for the ESC - I have just ordered the Caster Fusion plate, and will look for the Traxxas clip in the UK too. Thank you!

I see you have an MBX5 conversion - tell me, roughly what range of pinion sizes will fit (assuming you have the stock 46T centre diff and the RCM motor mount)? I am still deciding on the setup I am going to use - I'd like to be able to run both 4s and 5s, so I would need a range of pinions (well, at least two!)

Now I just need Mike to tell me that those motor mounts are coming back in stock so I can send him my order for the motor mount, battery holder, pinions etc...
