Juergen, in your July 22 comment, you mentioned the DX5e "would probably do". After 3+ years of looking for an alternative to DCC, I purchased a DX5e with AR500 receiver and a non-Spektrum reversing ESC for a prototype locomotive I want to build. I'm having problems with reversing the motor, which also only runs at one speed. Local RC shops don't seem to be able to help, even the one that sold me the equipment. Do you have an opinion as to why I'm having this problem? Should I have purchased a Spektrum ESC? I'll look forward to your comments, and anyone else's to get me out of this predicament.
Dan

Dan,
normally any fw/bw esc should work.
Tell me the name of your esc or make a copy of the instructions that you can send me.
What batttery voltage do you use and what is the voltage range of your motor?

Juergen,
Many thanks for the quick response. The ESC is by Associated Electrics, Inc., RC18T/MT, XPS Micro Electronic Speed Control, Voltage Input 4.8-8.5 Volts, Internal Resistance 0.0045 Ohms, 20A Continuous Load, 5V BEC Voltage, 1A BEC Current, 2.8KHz Frequency, w/Overload Protection + Reversing + Reverse/Brake Mode Switch. Around US$50.00 cost. Battery voltage can be 4.8, 6.0, 7.2, depending on battery type and quantity, and available space. I'm using a 6 Volt brushed precision Swiss motor because of low current draw, but can also use a traditional Sagami-type or Buehler 12 Volt motor. I cannot immediately send you a copy of the instructions as I do not have them on my hard drive. If you can advise your e-mail address, I will try to contact the manufacturer to get it by e-mail, then forward it to you. Thank you in advance for your time and your expertise.
Dan
Dan- I sent your Email addy to Juergen in a PM--not a good idea to leave it out where spammers can grab it Herb

Dan, with your specifications I found the instructions manual on the net.
You can download it here
http://www.teamassociated.com/pdf/cars_and_trucks/shared/XPS_ESCmanual.pdf
Your esc has a programmable "Forward-Only Racing mode" that should explain your problem with reverse.
Please follow the "Setup Procedure" in the manual and try again. I hope your problem with the single speed will then be solved as well.
Juergen

Here's another alternative for speed controls. Dimension Engineering has a number of ESC's and some very useful other electronics especially for monitoring LiPo batteries.
http://www.dimensionengineering.com/
Their speed controls have a high switching rate so you don't get that annoying whine out of the motor.
I have no connection with this company other than being a satisfied customer.

Juergen, many thanks for relaying the information. Incredible that their representative was not aware of this...still have not heard back from him.
I'll go through the procedure again, but replacement is not out of the question.
Regards, Dan

You may want to look at the Spektrum AR6400 Rx/ESC/Servo combo for your needs. I'm considering this item (abt. 1"x1"x1/3") for my prototype. Problem is I don't believe the ESC is a reversing one. Now if only this was an added feature, I'd be all set. I need to keep searching.

Dan,
yes, you believe right, this one has no reverse, it's a plane esc.
What's with your esc now? Is it working?
How about a picture of your loco?

Currently, the cheapest and smallest receiver/esc with reverse is LOSI LOSB0803 which fits nicely into a Bachmann On30 Porter and most everything else. I am still talking ancient 27MHZ control, but it does work well and is available and needs no other devices to make it operate. The KYOSHO Mini-Z board is smaller, but the 27MHZ is discontinued and 2.4GHZ is the one. More money also and a proper transmitter is needed also. This info is probably of interest to those who want great control at a cheap price.
It seems that many have forgotten that airplanes have NO reverse!

Hi,
the Team Losi receiver/esc board is now also available for 2,4 Ghz, and can be controlled with a Spektrum 2,4Ghz transmitter
As Dan already owns a Spektrum Dx5, this would be an alternative.
Have only found a complete conversion kit.
