Nice pictures, thank you for posting them. I was originally IC in most of my boat's, except 2 new ones that I purchased that had brushless in them. I had a couple with brushed and found them very slow for my liking. I have kept one as a recovery boat. I have since removed the IC engines and sold them on Ebay and purchased all new Brushless Motors to put into them. I am a bit of a speed freak myself.
