Having built many ESCs (electronic speed controllers) for fellow MGF/TF owners, I have now written a build article which will be put on Rob Bell's website sometime. In the meantime here it is:-



There's quite a bit of chatter on .org on this subject. Hope it's useful for some of you out there.

Nice one - could we add this to our how tos?

Nice one!

Good news for those with air con and a dodgy fan speed control resistor pack.

Hi Guys, I attach the fitting isntructions for my ESC which compliment the building ones. This is what I send out for anyone enquiring about my unit.

Is there a problem with opening these attachments?..
I can download but can't open

Hi Ian - You need Adobe Acrobat Reader to read the pdf file. Pm me your e-mail address if you are unable to open the files and I will e-mail them to your address. willyphixitt

I'm using a nexus tablet that normally has no problem with PDF files.
I'll crank up the PC. Now it's win 10 it can do anything in

Sorted on tablet , onboard PDF reader needed replacement!or educating?
Many thanks
