"Hello. I've searched but cannot locate an answer. I'm using APM 2.6 and Rover 2.5. After my 150lb rover almost rolled through my living room wall I'd like to enable arming :) Arming_required doesn't appear to be in the param list…"
"Hi Hi Tom - your rescue boat looks ideal - small, strong and maneuverable. Thanks for sharing. I'm lucky - several club members rotate to operate a rescue service on a non-official rota. Pics below. Many thanks."
"Sorry Grant, Tom and team - I've let you down.
Yesterday my shame circuits went into overload when I lost all motive power and had to request help from the rescue boat. On retrieval, I discovered my soldering skills leave much to be desired.…"
"Understood Thomas - thankyou and makes perfect sense.
To be honest, in Manual mode while sailing a straight course across the pond my boat hardly rolls at all (unless she hits wash from another boat). A lack of upperworks, relatively light…"
"Hi David - It goes backwards very nicely as long as you're not too concerned about the direction of travel :)
I previously built a tug with twin Korts and that boat steered backwards better than anything I've seen. But on this one, its a…"
The dual propellers on my Villain help to mitigate motor torque roll because each motor is counter rotating to its twin.
My lake rescue tugboat has only one propeller and therefore rolls slightly to one side (starboard) when underway. I can…"
"Hi Tom and yes - Kort Nozzle around the prop is rotated by a servo to provide steering (a bit like a very slow speed jet ski).. I didn't want to confuse the thread by referring to it directly.
Thanks for info on your Villain. I've Googled…"
After looking at your build pictures, you appear to be steering with the propeller that is in a Kort nozzle. Is that correct?
My Traxxas Villain hull steers with two subsurface propellers moved by one servo.

"You're a hero Grant - thankyou. I really appreciate the effort you've gone to and will certainly get back to you after the next outing (which will be on Sunday). Will try adjusting the TConst first as suggested.
"Hi Tony. I have attached some lovely graphs below :-)
RCOU.Ch1 is your rudder. In this graph you can clearly see the rudder going back and forth trying to compensate for the oscillation.
Now in the graph below we have zoomed in. …"
