I ripped out the 650 this past weekend. It was too much of a PIA to get the blaster chamber in with the tank installed, so I left the 650 chamber in for the past month. I am grinding down the lord mount today to get ready for the 750 motor which will be here next week. As well as installing the front exhaust outlet. I should have it ready to go in about 2 weeks.
I am installing the extra 650 motor in a spare hull I picked up 2days ago, and I will be doing test fitting with the lord mount and gas tank "tweaking" today. I'll post up some pics, I dont have an electrical box for the spare hull or I would have fired up the 650 with the blaster chamber today.
