Yes,spot on Jan,3 holes,well a bit more than holes,sortof moulded plastic underside holes.
Thats why i thought i'd keep it simple with a submerged prop.
It oriiginaly,a few yrs back,had 3- 600 size? motors and a very poor electonic speed control which didnt last long.We ripped out the electrics,the middle motor too, and fitted 2 esc's which ran very hot with 10 cells.The boat actually ran quite well,looked good too.But 2 10 cell GP 3300's didnt last long maybe about 4-5 mins.
I thought a single large brushless with a decent maybe 6s lipo would be much lighter and therefore quicker.
I'll see what my LHS has in with couplings for a 6mm motor shaft.
Is there such a thing as submerged metal props?..
I'll probably send for that big motor that was highlighted.
This uk store dosnt stock the right KV for me.
