Can't wait til the weekend....and need to convince "her" to join me down the lake to take a vid....first i will try the y leads feeding both ESCs equally, and if that works fine i'll leave as is. (who was it who used to sign his posts "if it ain't broke don't fix it!"?)

If not i'll hook up the mixer. If i understand the instructions correctly both ESCS feed into it, then one of its leads feeds into the receiver and the other one hooks onto the servo. It's a weird build for me, as i'm hardly following anything i learnt on my other projects - never run outrunners, never run twin drives, certainly not without cooling....and never had so many shiny new parts in one boat

In any case the micro-niceberg (is what i'm calling it until the first time she hits the water and things start going wrong) now weighs 760 grams with the lipos.

Hardware and electrics details are as follows:

2 x 2mm gundert wire drives with m4 stubs running in 4mm tubes and 2mm bushings at the ends
2 x 2mm turned alu motor mounts and motor aligners (with lube pipes) from gundert
1 x 110mm CNC alu rudder (from gundert)
2 x 33mm counter-rotating props (graupner k series are all i found at the lhs) - will try the robbe plastic 35mm with less pitch - but not really trusting them
2 x mystery 30A brushless escs
2 x mystery 3000kv outrunners (about 50 grams each)
2 x solid alu couplers
1 x hxt micro-servo
2 x 2s 1300mAh 20c lipos (loong max)

actually SV27 dayton....cost did matter (so i cut corners by buying the mystery combos - 60USD for everything)
