Thank You for your kind comment I hope to improve as I go and hope people get something from my videos

I guess for the same reason I didn't replace the whole drill. It would have been alot dearer for the whole board and take just as long to do. The mosfets cost me around $3 each and the board I only found including the motor and switch for approx $140 Thanks for your comment hope this helps

Thanks so much
