Humm, i know this is not gonna sound very smart but here goes...where exactly does the reverse module go, where does the mixer plug into, and where does the servo for the RM go too. Sorry about all the questions!
 
Actually, those aren't stupid questions at all :).

First up, the module itself goes in the transmission (obviously, lol). To install it, you'll need to yank the transmission from the truck.

The module itself fits in the bottom of the transmission. If you look at the front of the trans case, you'll see an oval-shaped "bump" that has a slot next to the output shaft. The reverse module fits into that relief, with the actuation lever coming out of that slot.

To install it, you will have to pull the transmission out of the truck, and remove the bottom shaft. You will also have to remove a "bearing carrier" out of the transmission (the two phillips head screws by the output shaft), and the gear from the bottom shaft.

From there, it's pretty easy to install it.

Now, the mixer is only needed IF you have a 2 channel radio. It plugs in-between the reciever and throttle servo, and actuates when the truck is at a full stop (I suspect the unit is like a gyro, but not sure).

The servo for the reverse module mounts between the steering and throttle servos in the radio box, output spline downwards. A standard servo is actually more than all that's needed here, since literally zero torque is needed.

Here's a snapshot of the servo and linkage:

I got the TF-3 hpi transmiter...do i need the mixer? It says ''digital proportional(....DAMMIT) 2 channel radio.''

If it's two channel, you will need the mixer. Unless of course, you upgrade the radio. Check the receiver, it may be three channel (will have four connector ports... one battery, three servo). If it is a three channel receiver, all you'd need is a three channel HPI transmitter.

I only have 3 ports batt, ch1, ch2. And i have that transm. View attachment 5418So...what is the use of those switch?

Those are servo direction reversing switches; don't touch those unless you need to change the direction of throw.

You'll definitely need the mixer for the reverse module, unless you upgrade the transmitter and receiver (servos are alright to carry over to a new radio).

If it were me, I'd upgrade the radio to 3 channel, simply to prevent the mixer from triggering the reverse servo under motion, which could cause the reverse module to be damaged.

Andddddddd how much thoses baby go for? Any example?
 
:thankyou: Thanks Heartbreak!! I'll maybe choose one of those...:bow:

Did it ever happened before?? Your scaring me...
 
LOL, nope, I've been lucky enough to not shred the reverse module. It's really common sense; just come to a complete stop before changing directions.. Kinda like a full-size transmission.

It's actually a pretty solid design. In forward, the gears that switch between forward and reverse lock into each other, kinda like a servo horn. Pretty genius idea.

I dont get it tho, if all my port are taken(batt, ch1, ch2)...where do i plug the mixer??
 
It plugs into the 2nd channel, then the throttle/brake servo and reverse servos' plug into it. Kinda like a Y splitter with a brain.

It probably has a gyro in it to sense motion. The concept is when the truck comes to a complete stop, the reverse module will actuate. Either that, or it takes a second brake-press. I'm not sure which.
 
Ah ok!!! for a second i though of having to spend more $$$. Thats some weight off my back, Thanks again!
Dont think i have any other question for now about that...LOL:celebrate:
 
lol, no problem. Either way, you'd have to buy a standard servo. Either a hitec 303, an airtronics 94102, or a futaba 3003 will do. Unless, of course, you buy a full radio set that comes with a transmitter, receiver, and two servos. Then, you're set all the way around.
 
That's a perfect link, Rossb. You can see why it's a recommended thing to install the three speed at the same time (or vice-versa), since you have to remove the trans case to install either one.
 
Hi, you can get a much better deal than tower hobbies on almost anything. I bought my reverse modual on ebay, with the mixer, and it came with all the install hardware and directions for under $60. I also have 2 speed transmission complete with modual installed, servo and mixer for 125. The reverse modual is not too hard to install if you have a knack for that kind of stuff. Just be careful and clean when you take the trans apart. Oh, and the mixer works of timing of the brake servo. After you hold the brake for more than 3 seconds, it will shift into reverse, and again, out of reverse after you hold it for another 3 seconds. It works well and insures the truck is stopped, not like a 3rd channel, where is is possible to hit reverse while jammin at full throttle. Good luck!
