Unfortunately or fortunately planks have to be sanded so that they don't look like planks on a steel vessel
Not needing to use filler is a bonus in saved time and effort but can improve your best attempt as in my Boulogne Etaples build.
On with the build but not much progress.
The electrics fit conveniently with the supplied double sided tape.
The batteries arrived yesterday and after testing them I changed the deans to XT60, a potentially dangerous operation if not planned carefully.
This newer style XT60 is designed to not need heat shrink which is fine on the load side male connectors BUT on the female battery connector its important to deal with one wire at a time and insulate it to guard against accidentally touching it with the other wire while trying to solder it. The heat shrink conveniently came with the ESC and I didn't need it for that.
I stuck two blocks of paxolin to the resin to be able to bridge the keel with the battery. A strip of rubber then made a base for it and some blocks of wood in front to keep the hard case battery in place.
