Still building mine at the present. But I have 2 x 380 on the outer shafts which will drive 30mm 3 blade plastic props. Centre motor will be a Leopard 2826/17 brushless driving a 35mm(?) 3 blade prop.
If that doesn't work I may change the outer motors to brushless at a later date.
Esc for the brushless will be the 30 amp marine from Component Shop.
