The point of a mixer is to speed one side up and slow the other or speed one and reverse the other, in conjunction with the rudder position, this allow the boat to turn better & faster which is what is required with this type of boat considering its job basically it has to spin on the spot, the mixer along with the bow thruster will aid in that ability making it very manoeuvrable. This is a twin prop set-up not a singular, with fixed kort's not 180 rotating.
I fail to understand your point ' If you only have to push button to store the 100% throttle point then where is the problem?' there is no problem i know what im doing and how to achieve it, my only question is and has been since the start is that will my set-up i have picked do the job i need or are there other or cheaper ways of doing it.
Fitting twin mtronic esc's require them to be programmed to the max and min throttle before use, or your going no where!, the use of the mixer enables me to control throttle for both motors and turning in conjunction with each other on 2 channels, the bow thruster on a 3rd, and the winches in and out on the 4th and the 5 will be lighting or something similar.
the Action p94 does 2 esc's and a mixer in one unit but at a £80 cost my alternate suggestion would decrees the overall cost by around £20 which is half the cost of the p40 mixer paid saving me money.
I don't mean to be rude but your last 2 posts haven't helped at all im not sure if you haven't understood my original question correctly in regards to my set-up. i would ask polity to go back and read my original post and make sense of what i have asked to what you have said , you comment over 100% programmed throttle is meaning less in conjunction to the mixer doing it job over 2 esc's and motors, my 2nd reply was based on the fact that vtail mixers generally are not programmable, and i would rather use An Action mixer in this case as 'vtails from planes' really are for planes' there are more factors in play with an aircraft that enables a normal vtail to do the job thats why there normally 100%/50% where as the action allows the programmability of controlling each esc separately to aid in turning on the spot, one thing air craft ( excluding helicopters) can't do.
As i said there is no issues with my set-up, im generally checking if its going to work as well as i hope it will, if there are other set-ups that will do the job better, or if there are set-ups that do the same job cheaper.
