Greetings!

So much to learn.  For the 2.4 GHz fans, I have new information that may be of interest.  According to the gentleman I spoke with at Horizon Hobby, the best thing to do with my Spektrum DX5e is to purchase an AR6115e receiver and a Losi LOSB 9530 ESC.  This will provide a proper Tx/Rx/ESC link to obtain proportional speed control and reversibility.  The previously mentioned Losi Conversion kit probably includes components which use DSM technology vs the DSM2 technology in my DX5e Transmitter.  A problem for me would be not being able to use the several precision brushed motors I have as the above ESC is for brushless motors.  On the other hand, brushless motors, especially sensored ones, are more efficient and have better low speed control.  Decisions, decisions!  More to come!

Dan,

what's up with the esc you already have? Have you tried it again following the manual, as I recommended to you ?

No need for a brushless esc, any brushed esc with reverse will work. And the choice of esc has absolutely nothing to do with the use of 2,4 Ghz.

No need to buy a another receiver, any Spektrum receiver will have a perfect connection to your Dx5e.

Juergen,

I'm pleased, in fact delighted, to advise the successful operation of my 2.4GHz RCC (Radio Command Control) system using the components described previously.  I was able to achieve forward and reverse and with variable speed.  Operation was smooth, and better than expected.  Going from forward to reverse is seamless, with just pulling back slightly on the throttle stick. 

I'm off to the local hobby store to investigate smaller components, as I am a bit oversize on the Rx (receiver) and battery pack and need to fit the chassis into an AMD-103 shell.  Tonight is my train club meeting, where I will try a sustained run instead of just going up and back on my test track.  I will post some photos shortly.

Dan

Juergen,

I should have been more specific in my last commentary and mentioned that the components I am using include my Spektrum Tx and Rx, and my original ESC and 9-pole Swiss motor.  I've added a flywheel to maximize smoothness.

Hi Dan,

Fine to hear that you had success with your esc.

The smallest receiver available for your Spektrum Transmitter is the AR 6300, that I have already shown in this thread somewhere above. It also has much smaller plugs than a standard receiver.

The smallest esc I have found for me up to now, is the one from Sol Expert, also shown in this thread. Only disadvantage, costs for postage from Germany are expensive.

Alternative option, the Team Losi 2,4 Ghz micro-T board, that combines esc and rx in a single board and that I have linked for you a few posts above.

Juergen

I talked with Losi Technical Support on two occasions and an R/C specialist at a local hobby shop about the 2.4 GHz Losi Conversion kit.  They all tell me to expect incompatibilities using this kit with DSM technology and my Spektrum DX5e transmitter with DSM2 technology. I will be contacting Horizon Hobbies to try and get an official recommendation.

The prototype model I mentioned earlier was run at my train club meeting a few weeks ago.  It performed well on and off for over an hour without discharging the batteries.  I used four 1.5 volt alkalines, since I haven't settled on the Lithium battery type I will ultimately be using.  In summary, in my opinion, RCC (Radio Command Control) is a practical alternative for running HO trains with several advantages, not the least of which is prototypical looking track, to match the great looking models we now have and have come to appreciate.  My next step will be speed control refinement and looking at smaller components for a better fit under my locomotive shell.

I tried earlier to post a photo, but lost the accompanying text as well.  I tried to "drag and drop", but this didn't work.  Can anyone advise how to put up a photo?   

Dan

Photos: go to the homepage, click on MENU, then click on GALLERY. You should have your photos on the desktop or somewhere else that can be accessed in your computer, Click on UPLOAD PHOTOS. Then click on BROWSE and select the photo(s) you want, then click UPLOAD at the bottom of the screen. When it's done, your photo(s) will appear in your gallery. When you post a message, click on the big G (upper right icon) and select your photo, click on it and it will appear in the post. Easier than I can explain. Good luck.
Woodie

Woodie, re the photos, thanks, I'll try to post one this evening.

Dan,

DSM technology is downwards compatible. Your DSM2 Transmitter can handle the DSM as well as the DSM2 protocol.
I myself use the old Spektrum DSM receiver together with my DSM2 Dx6i and DX5e.

Well, here goes!

You are looking at four 1.5 volt alkalines in series, a Spektrum AR500 Rx, an Associated Electronics reversing ESC, a 9-pole brushed motor w/A-Line flywheel, all mounted on a Hobbytown frame with gear tower and power trucks.  The universal shafts are custom made.  Extensive testing and optimization is next.




Future power will be via paralled LiFePO4 rechargeable batteries (for safety). This was only to prove to myself that RC for HO is feasible.  Whatever components are used to reach the common objective, it would seem now is the time for me to put it all together and lay down some track MY WAY!    

Thank you all for your helpful comments.

Dan
