Ok...
Currently trying to build a Itaieri Schnellboot, ...but am questioning if what little I think I know to be correct/ workable... I have amassed the following :
3- Hobbyking ST3007 1100KV brushless motors each direct drive to 32mm plastic props.... (2 right hand drive and 1 left hand drive props... swapped over leads on on motor to get it to run as yet untested the left hand prop)

3- Turnigy nano tech 3s 3000mh 25-50C Lipo ( Have got a balance charger and board , flame proof charge bag , battery voltage check/ alarm units, and will check and charge them await the only local help I have in RC / lips battery a helicopter flyer who has no experience with RC boats )

I just read the post on WTail mixer and wonder if I need that or if my current unkowning idea to just connect all 3 ESC ‘s together to one channel on the radio , again was give Eflite Blade SR HP6DSM 2.4GHz to try out ,Will this unit work or do I need something else , currently will/ can use all 6 channels but would / could use more if I had them ... last time I had anything to do with RC was a a kid/ teen and back then you had ground radios and flight radios and the two should not be mixed .. Ok please advise , how far off am I or am I still within range of keeping it simple ?

Thanks All
Bill

I recently tried 2 ESC(s) into one battery connection then into 2 channels of the radio. Received wisdom said that one of the red leads to the radio should be disconnected. This I tried and one ESC ceased to function. So to prevent unwanted feeding on the positive lead from one ESC to another I fitted a diode to each of the ESCs. If you were to do the same I think your setup would work. However if your TX has mixing capability then why not use that ability to mix rudder with the 2 outboard motors so you have the added steering of the 2 outer motors? Any how fit the diodes please this should prevent the ESCs damaging each other its a simple job

20 diodes for £1 the silver band is positive so goes towards receiver plug.
