Les Knoll: Excellent! I've tried to address this very situation to other Live Steamers here before but you do it so eloquently. I'm an Aster kind of guy, but not so "purist" as you put it that I INSIST on hands on cab control. My Solution to the Aster problem has been to still use Aircraft model servos, but that have been modified to accomodate the allowable car-truck toy freqs. for reception. Got a local "Black Box" guy here that knows how to do this, not me. Problem is of course that on the Asters, a typical toy Car/Truck servo is not strong enough to operate the steam control valve OR the reversing lever. Especially the Steam Control Valve. It has to be able to be closed tight, AND to be opened to full throttle and Aster builds theirs with close (ergo tight) tolerances. When your willing to pay 3k-4k for a steam loco, you expect to GET your money's worth, and from Aster, you get it. When I'm not running it, it sits in a glass display case in my living room for all to see. You bet I'm proud of it. I built it. I'm getting ready to tear into the Roundhouse S.R&R.L my loving spouse bought me for my birthday. It comes with RC, but I have a feeling that if I don't like the way it works, YOU are the guy I should talk to. I'm NOT and RC expert myself. I only know how to play with it and hopefully get it to work right. I have a couple of photos of the conversion I've done on my Aster C&S and would be happy to forward them to you. Since you ALSO seem to be a guy who is up on your Walschaerts and Stephenson, I published an article to the web about 4 years ago showing how Aster applied the Walschaerts to the C&S with only a slight modification and why it required this modification. It comes with scanned drawings going back to the original Patent by Egide Walschaert, and scans from the Aster manual, reproduced with their expressed written permission to do so. Many people confuse the C&S motion with a Stephenson. It most cretainly is not. It is a Walschaerts and I can demonstrate it clearly. It also demonstrates the clear difference between the two. With the help of a couple of other web sites that I provide hot links to that still work. Many confuse these two motions, even SOME long time live steamers. If you are interested, I'd be happy to forward it on to you. Regards, LDH
