DW-the HO front end loader is great! The builder didn't tell about what kind of r/c unit he is using but judging from the model, he may have built it himself! He mentioned IR which is infra-red technology, similar to the TV clicker. What we have been using is "hobby grade" radio control that is different from IR. With r/c, the frequency can be changed by changing the frequency that links the transmitter and receiver. Also, r/c has an effective range of several hundred feet at the least, IR  works when the transmitter is pointed to the receiver-just like the tv clicker. The front end loader is a very cool model and maybe the guy will tell more about it in the future. What you are looking for is PROPORTIONAL SPEED AND DIRECTION CONTROL in as small of a unit you can find. My friends & I have probably became aware of maybe 10% of what's available so there is much more research to do. I am trying to explain what I have done, not promoting some product, and I am having too much fun running and building my layout to really devote the time it would take to "surfing the net" for everything that can be used. I have been using r/c in my On30 and lately 3/8n20 locos for probably 4 or 5 years and have had no problems with any of the equipment I have. I am also fortunate to have a good friend who builds r/c planes and he has given me much help and advice along the way. I have been building model railroads for about 50 years and really never had the fun I am having now with the added dimension of radio control. This one thing has freed me from having to build my layout with concerns about wiring, dirty track, and other problems. Since I have no electrical concerns now, if someone connected a power pack up to my layout, the rails would glow red and the power pack would go up in smoke but my locomotives would still run with no hassles! Real railroads don't have wires connected to the rails nor do they run off track power.....so why should my railroad be any different? Whew, I'm up on the soapbox again, but I feel that I can actually say these things on a site devoted to r/c trains.

If you have a Bachmann On30 2-6-0 or 2-8-0, get a TEAM LOSI MICRO-T CAR receiver(about 30 bucks), an inexpensive FUTABA 2 stick car radio(about 45 bucks), an alkaline 9 volt battery (maybe one buck), a battery clip for that battery (also about a buck), and a receiver crystal that matches the Futaba unit's frequency, or a set for another frequency(about 8-12 bucks) and get to work wiring it up. Just isolate the motor like you would do for dcc, and hook it up to the motor output wires on the LOSI board which now resides in the tender along with the 9 volt battery. Put batteries in the transmitter, turn it on and then turn on the loco's board and get to running wireless. That's all there is to it! After the first job, you will be an r/c expert and can do other locos and amaze your friends. Some of them will think it's all craziness, others will be unimpressed, but your friends who are open minded will want to join you and use their power packs as boat anchors. Welcome to the dork side!

The possibilities are numbing. :Brilliant: I used to race R/C many years ago and have tons of the stuff packed up, now I need to catch up on the new battery technology and the changes in the transmitters so hopefully I can convert my engines to R/C. I do have a question about what you do with the the antenna, put it on a stick like we used to do in cars or just coil it up at the receiver?:glad:NO MORE WIRES!!!!!  This could be the start of something GREAT!. :cool:

Thanks for the encouragement.  I've removed the board from the car.  Glad to hear you say they should be able to handle the 9V, 'cause that was my next question.  I'm not willing to go hacking at the board either.

You're point about the locomotive is well taken.  I've 2 On30 Bachmann Spectrum Porters, a Shay and a Mogul.  All well broken in and smooth running.  I'll probably try it out in the Mogul first just for ease of instalation.

It's going to take a couple of days before I can get to it.  My schedule right now is forcasting 12 hr work days until this weekend.  Then comes the "Honey-do" list....etc.

Oh yes, the antenna!! Since I am usually no more than a couple of feet away from the locomotive, the antenna placement is not as critical as it would if I were across the room running a train. The wire from the board that connects to the longer antenna in the r/c car is about all I am running. You shouldn't coil the antenna wire since that would cause some problems. I tend to run the antenna wire out and try to glue it down in a more or less straight line. Then I can paint it blabk or make it look like a piece of hose or rope laying on the loco somewhere. The antenna is the only thing you will have to mess with, all my locos have different installations. As I stated, I am never far from the locomotive so for me this is not that critical. My railroad has some twisty and bumpy track, covered with weeds and sometimes a derailment may occur-if I'm not being an attentive engineer!  Remember that if you do derail, the train will keep on going across the scenery, just like the real thing. If you just like to watch trains run round and round, r/c may not be what you want but if you like to operate, pick up and set out cars, then you will love it. Experiment with the antenna placement, I think each engine will be different. It might help to do a little antenna research, but that's up to you. Have fun.

Let’s see if this helps. My little 0-4-0’s are too small to put much of anything inside so I’m going to use a trailing boxcar to hold the battery and receiver.

 

I started with a regular 9 volt battery holder. I turned it upside down and built a little bracket to hold the receiver.



 

Here is the receiver mounted on top. The red and black wires are connected to the battery. The orange and blue wires go to the engine. I’m using a little connector for the engine so I can easily switch the engines.



 

Here’s a pictures of the whole thing in front of one of my 14 scale foot On30 boxcars. As you can see, it will easily fit inside.

 

That’s all there is to it.

Nice Job Bob!!  Pictures always Help......:thumb:

So is that a little On Off switch?

What is your plan on mounting it? Underneath the car? Inside the car unmounted?

As to the antenna........Whats the plan there? Can it be hidden under a roofwalk and still be functional?

Can the antenna be removed and a Smaller diameter Wire used in its place for signal reception? Would a Metal Ladder assembly made of brass work for example?

My thought would be a Brass ladder with the big looping handles on the end of a boxcar with the entire ladder as an antenna....Mounting pins go through the side and wires are soldered to the pin ends........If this isnt enough, Perhaps extend something like a pole for a signal flag........OR.......add a railing along the centerwalk of brass wire......(ive seen a roofwalk handrail on a proto photo but they must be unussual at best......still, it is a possibility if necessary.

Woody??? Any thoughts on this?

Good points Todd. The on/off switch is part of the receiver. I’ll mount it somewhere that it is accessible. I plan to just drop the whole thing into a box car. I might make a frame to keep it from moving but I want to be able to remove it easily to change the battery. (I haven’t had to change it)

 

I plan to just loop the antennae inside the boxcar. I’ll see how that works for starters. My final plan is to build a MOW car and hide the antennae like a piece of rope of something. If that doesn’t work, I’ll get with the RC guys and figure out how to increase reception.

 

Right now, I just have it sitting in a gondola. Works great.

I haven't really worried about antenna placement with my locos, whatever seems to work is OK for me. I realize that some fellows may want to stand off a ways when they run a train, but I am close...maybe no more than 2 feet away, so if I can control the model at that range, I'm fine with the installation.  Receiver antennas SHOULD be laid out in a straight line and not coiled back on itself. In that perfect world, the receiver antenna should be around 38 inches for 27MHZ receivers, but that would be for (as an example) controlling an r/c car at a distance or a sailboat out on the lake. I have seen the 38 inch antenna carefully wound around (not touching) a piece of plastic tubing which can then be hidden inside a small boxcar, etc. Experimentation is the word here.

One thing Bob hasn't brought up is the "Captain Kirk space pistol" transmitters that are associated with many r/c cars. Bob is using a nice Futaba 2 stick transmitter which is acceptable to most modelers, the pistol grip transmitter is kind of strange and alien to what we want to do. I have taken a couple of these units and put the components into Radio Shack boxes which look like a normal wireless throttle. It takes some fiddling, but is easier to use and looks like something everybody uses. On Bob's transmitter, he has installed the throttle "detent" which makes his throttle stay wherever he sets it, mine have the center off "dead man's" throttle in place. I thought about changing to the way Bob uses, but am now familiar with the spring throttle and matter of fact prefer it since sometimes I get "tripped out" on something and take my thumb off the throttle-the loco stops, keeping from hitting something or taking a dive off the layout. That's just my way.

Bob is showing the way to do things, he is an innovater and true modeler. I thank him for bringing his work to us all.

Hey all,

If you have the new August issue of Model Rairoader turn to page 69.
Radio control is talked about in a article titled "where will the hobby go from here?

If I could recharge with track power....

 

It would be a better option. :)
