Managed to get a bit more done.
Fitted the Etti motor mount after reinforcing the mount area with some slow setting epoxy,very slow drying,its the supposidly 30 minute stuff from Hobbyking,more like 24hrs,nice and strong though..
Painted the inside with some car engine enamal,quick drying and fuel and water proof,looks a bit neater and easier to see if water is entering the hull.I try to do all my hulls with it.One coat is sufficient.

The original Shockwave flex is a .187 flex with a .187 stub shaft,my motor coupler is a .150 collet and i have a few spare 150 flex,187 stubshaft,so i fitted a 150 flex stuffing tube inside the old shockwave 187 stuffing tube,it fits great.
Filled in all the deck holes with some 5 minute epoxy and shoved some wet paper mache down the rear 'exhaust' stainless tubes and then filled with some slow drying epoxy.
Also i cut the radio box out of the hull,not needed with FE tape,i crafted a servo holder from the old radio box and glued it in place.

Fitted the motor 4mm connectors onto the esc and fitted some 5.5mm for the power leads.
Cant go much further until i test the empty hull in the bath tomorrow to check for water leaks.

Plus programmed the Seaking 180 esc.These escs dont seem to like a cutoff limit for lipos,cutting of at the wrong voltage.
I always program them for 'no cutoff',and they seem to work well.Its obvious when volts are starting to drop a bit when we run our boats and then bring them in slowly.

I am also going to angle the turn fins as i've read thats the way to go for these hulls.
Also going to trim the rudder down a bit in height.
