Not much to say in favor of time delay operation? I have the Accupower Pilot. Is the proportional type superior in every situation or only in a panic stop?

has anybody actually wired one of these themselves, i have the blue wire hanging there under the dash, so i just need to find the cold wire on the brake switch, and run a hot and cold to the battery with a circuit breaker. this reminds me of working under the sink just not right for my 67 yr old back of course the rain and snow does not help but i just can't seem to pay the $200 bucks for something i can do myself.

Yes, I done exactly what you describe, except I ran the blue wire from the back, also. Worst part is bending over and twisting to get it all hooked up.

You said initially that it has the factory tow package with the 7 pin connector. Would that indicate that you could purchase a plug in adapter as opposed to tapping in manually?

Jack I have towed with both an inertia activated control which I am assuming the Accupower Pilot is and a proportional type and IMHO the proportional type gives you a much smoother stop for all types/speed of stops as it starts to work as soon as the drive applies the tugs brakes and matches the same amount of braking power to the trailers brakes. Not sure if thats the info you were looking for or not.

Thanks Carol. I know my Pilot is inexpensive and barebones in terms of user control and appears to work adequately. I have no experience of other/better designs so looking for a comparison.

Per some confusion of terms used:

"Inertial" and "proportional" are interchangeable terms, both denoting a single type of controller. That/those controllers operate differently from "time-based" units, and here's a link that explains how way better than I can:

Nope no confusion Francesca. When looking at the various controllers out there you will find there are actually 3 kinds (or at least 3 I am aware of) that are commonly offered for RV's. Walk into any supplier of controllers and most will refer to the 3 types as Time delay, Inertial and Proportional or at least thats been my experience.

As I indicated I dont know what Rabbits actually is - didnt look it up but its either a Time delay or Inertial type.

There is actually a difference between what is commonly called an Inertial and what is commonly called a Proportional brake controller. You will find more info and examples of the makes/models of them at www.brakecontroller.com

Edit to add: A better explanation of the differences between what are commonly called Inertial and a Proportional controllers can be found at Ehow

I don't think the Pilot is inertial because the inertial mech requires that the body of the controller can only be mounted a certain number of degrees out of level at which point the inertial lever does not function. I don't think there were any limits on mounting in the instructions.

jack

addendum: checked eTrailer description. Pilot is a "time delay" controller and is not sensitive to positioning relative to a pendulum.

There are two kinds of controllers sold at that link- timed, and proportional/inertial.....unless I'm somehow missing the evidence as to which of the non-timed controllers work by anything other than inertia while applying proportional braking. I'm presuming you read the explanatory link I posted earlier as to what that means.

Rabbit your right yours is probable a time delay - used a number of years ago and I think you would notice a big difference under all braking conditions with a Proportional type controller.

Francesca, I am aware of what the meaning of proportional as well as inertial is. What I am attempting and apparently not doing well at ;-) is to try and tell you that the two terms are/have been used in the RV industry to describe two different controllers that work some what differently from each. I realized after I posted the link that they only went so far as to indicate there were indeed as I indicated 3 different types of controllers as I indicated. Didnt take the time to look down to see if they actually showed or fully explained the difference. See the second link for a better example of the differences between the two. I did as indicate own what was called an inertial type controller a few years back and now own what is being called a proportional. Whether or not any of the makers actually still make a what was know as a inertial type is another matter.

Are you guys talking about those with an internal pendulum as opposed to an accelerometer to sense deceleration and provide proportionate braking?

Am I crazy for even entering this discussion?

Yes.

Well, CAROL might be...

Though an "accelerometer"-type controller is STLL an "inertia"-type controller that applies proportional braking...

herewith, a description of one such controller: the http://prohitches.com/reflex-brake-c...-accelerometer
Quote:
The Reflex brake controller with dual-axis accelerometer is the best brake controller Curt makes! This inertia brake system applies equal pressure to your trailer's brakes as is applied to your vehicle's brakes, ensuring the best in stopping performance.
Is it possible that what we're really arguing about is what "proportion" is relative to??????

Francesca

P.S.

Per your second question: Prolly so.

Thank you Tom!!! LOL You've got it!

And yes Francesca what I was attempt to tell you was what "proportional" is relative to what the RV industry likes to call it correctly so or not!

The big difference that I recall between the two types is that a TRUE Proportional controllers such as a P3 keeps the trailer braking powered as long as your foot is on the pedal, even when the tug looses traction or the tugs brakes failed completely. Minor but it can/does make a difference in wet situations if you do a sudden stop of a wet surface and the tug starts to skid a little. With what is often referred (or at least use to be) to as an inertia controller it would not do that. Have a controller that works such as the P3 does is a much better system in regards to stopping the trailer in all conditions. But thats just MHO
