Hi all,

Read this series of e-mails from bottom to top in that order..
I have been "talking" with the guy at SIMPLY 7/8 th's locos about their new radio control unit.
It seems this co. has already jumped on the R/C band wagon and is offering their new locos with R/C installed.

Hi Larry, You are correct!, this is a simple hand held transmitter
not unlike the one used on vehicles, ours has three buttons-
forward, reverse and emergency stop. speed is selected by clicking
the required direction button, to reduce speed click the opposite
direction button. Come un-stuck press the emergency stop button.
The reciever dimensions are 55mm longx 20mm x 20mm. There are
two  colour coded wires either end, two to motor and two to battery
isolator switch.  Prices to follow shortly.
 
Thanks for your enquiry, regards Mick.

Hi Mick, I must have missed something along the way..... what is this Key Fob
remote control unit? Is it a radio control unit for on-board control of the trains?
If so, what are its dimensions, price etc.

Hi Folks- Good news from our electronics dept.
> The new Key Fob remote control unit is working perfectly.
>
> We now have our own all singing and dancing micro chip.
>
> As soon as 'Baby Sim' arrives with the control fitted I will
> post Trev's mail address and anyone interested in the unit
> can contact him directly.
>
> All Simply 7/8th's loco's will be fitted with this control
> from now on, manual control by request.(who needs it?)

Happy modelling, Mick.

THis 7/8 scale radio gear looks(sounds) interesting. The board seems reasonably small, but it this radio control or remotre control? There is a difference. Remote control is akin to "tv clicker" technology and the "transmitter" has to be aimed directly at the receiver, radio control can control over long distances and the transmitter doesn't need to be aimed at the receiver.  The little Kyosho car r/c units I use are 20 x 20 x 40 MM and the removable crystal(part of the 20mm height) can be relocated anywhere making the board about 10mm thick. It's great to hear that more folks are getting into r/c, a forward-thinking manufacturer could reduce the board size to that of an N scale dcc board, there are new li-poly batteries that could fit into N scale. These are marketed by TEAM LOSI for their Micro-T racers. The 7.4 volt lithiums are about as big as a postage stamp and maybe 10mm thick. Keep looking at new stuff, we are experimenting here and anything (almost) goes!

Woodie,

Here's a questions for you. What differance, if any, does brushed ESC VS brushless ESC make?

Bob

Bob-brushed esc is a speed control for motors with brushes like all we use in model railroading. Brushless esc is for brushless motors which (to my knowledge) can't be used in our trains. You know whaqt a "regular" dc motor is like, a brushless motor is similar to the old rotary motors in WW1 airplanes, the prop shaft is part of the crankcase and the pistons are mounted to the firewall, the motor is like that, in other words, the motor case rotates with the prop and the "commutator" is stationary. Is that a good confusing answer?? A good brushed edsc would work for model trains, provided it has reverse. One of these small esc's and a micro receiver would take little space in a loco and the 2 boards could be separated and wired together thereby "making more space" available in the loco. How's that for an answer?

OK mighty Grasshopper. Here's your next question. The RC guys always ask "How many turns"? How do we answer that?

Bob-that question concerns r/c car motors. The less number of turns, the better. They want the electric motors to go FAST while model railroaders are concerned with S L O W motors. In a Sagami motor, there may be hundreds of turns. More is better! The r/c car guys look for motors with big honkin' wire wound just a few times around the commutator. In r/c electric planes, to push a propeller, "can" motors like we know need a gearbox to provide the speed & torque, otherwise they use brushless motors(as do some car guys) which have the speed & torque so they don't need gearboxes. We should be glad that we have nice smooth small motors that don't use much juice and turn relatively slowly. Do you remember the Athearn Hustler? Way back then, we probably would have liked a fast motor when we raced Hustlers. All we needed was 2- 6 foot sections of flex track, one power pack connected to both tracks, 2 Athearn Hustlers, and a couple of pillows at the end of the tracks. Guess what we did next???

Not RC Woodie, but your comment about racing hustlers reminded me of back in my wasted youth, I laid Lionel "standard" gage track the whole lenght of the house and put my 408E at one end. Kept jacking the transformer voltage up, trying for a new land speed record. Then two transformers in series- still not fast enough. Then my widdle warped mind had the solution! Straight 110V from the wall outlet! Ready, set, CONTACT! Loco jumped straight up in the air about a foot, and fell with a hell of a thud on its side, the driving wheels seeming to take forever to stop. After this event, the darn thing still worked OK. Now try THAT with battery power!

Herb-you got me there! However, the rechargable Li-Poly batteries I use CAN sometimes explode! These are the same things that smoked Dell computers occasionally. Actually, if one is careful and doesn't try to fast charge Lithiums, there's no problem. I have seen a 3 cell, 11 volt battery go nuclear and melt down. Whatta sight that was, probably like your Lionel loco shooting up and down with the wheels spinning! You know, some of the early electric trains ran off 110, you put the train on the track, plugged the cord in, and ran for cover or to get a candle started since the power line got fried. Ahhh, them was the days! The old Hustler races were in conjunction with the Model Motoring slot car craze. If the car guys could have fun going fast, then model railroaders should also. I know a fellow who actually has an old Athearn Hustler that he put a propeller out from the hood. When he ran this thing at a local club, everybody was dumbfounded. The loco sure found places where the ballast wasn't glued down and cleaned the cobwebs from the "hidden" staging tracks. But then, there was the clearance problem with the propeller, it took out some loading docks and almost caused some guy's brass Challenger to hit the concrete canyon. Needless to say, my friend Bob is no longer welcome at that club....or any others in town.

Woodie,

Glad to have found you again!!!

An update!  I've got 6 R/C projects underway.

1.  Sn42:  A Losi board and 9-volt battery going into the back of my Matchbox Acorn Moving van powered by an old style Bachmann GE 44-tonner power truck.

2.  Sn42: A Losi board and 9-volt battery going into the tender of a Barry McClellan On30 to Sn42 4-4-0 conversion on an IHC chassis.

3.  S standard gauge:  A Kyosho board going into one of my hardcoupled pair of boxcabs (or juice jacks) bashed from a pair of AF caboose bodies.  They are on separated power trucks of an AF GEEP that had been remotored with a can motor by SnS.

4.  S standard guage:  A Kysoho board going into my Bachmann On30 Mogul that has been regauged and bashed into a Wannabe USRA 0-6-0 using a pic of the EBT's #6 as reference.

5.  Halfinch-42 inch gauge (Hn42):  My son's old Futaba radio with a tugboat ESC going into a reworked Hartland-Locomotive-Works Mighty Mack Switcher.

6.  Hn42:  An AristoCraft Trackside Trainengineer and batteries going into a tender for my Bachmann 0-4-0 Paul Bunyan Porter.

So far all the stuff has been gathered up and now I hope to get some of it working!

More later!

Don Munsey-excellent news!! Have you donated your antique power packs to a museum yet???!!! Actually, I still have one power pack so I can run-in mechanisms before I fix them with r/c and I still do some custom painting and building for a couple of guys who still use dc so I guess I'll keep the old thing.  Keep up the experimentation and let me know what's happening. Here's some news (unexpected)...the group that I am no longer a member of (uno who) want me to do a...gulp...r/c clinic at the Fort Worth & Plano train shows!!! There must be some kind of alignment in the planets or maybe the moon is full, but how about that?? Maybe you can get over to the Plano show (in Jan.) so we can jabber about choo choo's.
