Well, at least I know Ed is and I suspect that Gordon is too although I have not met him personally. Don't try this at home... OK, if you must know, they're building transmitters with custom encoder modules. Basically a "computer" transmitter built out of the old (high-quality - not cheap plastic) guts combined with a micro-controller based encoder. Lots of fun!!! I guess I have to build one now too.

Yes, kiddies, there were times when even the top-of-the-line transmitters didn't have dual rate switches. I'm no electronic genius, but I bought the parts and did the installation of dual rate elevator and aileron switches in a Kraft KP-7Z transmitter. They worked great and I can still remember the amazed eyes of my club members when I demonstrated how they worked.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Ron Van Putte<BR><BLOCKQUOTE type="cite"> <BLOCKQUOTE dir="ltr" style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV class="OutlookMessageHeader" dir="ltr" align="left"><FONT face="Tahoma">-----Original Message-----<BR><B>From:</B> nsrca-discussion-bounces@lists.nsrca.org [<A href="mailto:nsrca-discussion-bounces@lists.nsrca.org">mailto:nsrca-discussion-bounces@lists.nsrca.org</A>]<B>On Behalf Of </B>Emory Schroeter<BR><B>Sent:</B> Tuesday, March 14, 2006 9:41 PM<BR><B>To:</B> NSRCA Mailing List<BR><B>Subject:</B> Re: [NSRCA-discussion] Looking for a Proline Tx with Chidgey sticks<BR><BR></FONT></DIV> <DIV>Alright.

I'm just about done except I have to get replacements for the resistor networks, having 8 pin SIPs instead of 9 pin - whoops! Those are 6.8K, correct? Other than that, I haven't run into any snags yet, but I will definitely take you up on your kind offer to assist if needed.</DIV> <DIV> </DIV> <DIV>I thought I saw something about source becoming available for the MP8K, but I didn't realize the mstar 2K would be open source - very interesting. Looking forward to the upgrade as well. Re. the PulseStar receiver, that looked really interesting too. Did the MC13111 really get discontinued? It's a shame if so. I have to say, the projects you have done are really admirable. It's great to see this kind of project still available these days. I built a Heathkit GD-19 when I was a kid, when it was still fairly common for hobbyists to build their own stuff, including servo kits from World Engines etc. That Heathkit still works, KPS-9 servos and all and I flew with it right up until the mid 80's, though I did eventually replace the receiver with an Ace Silver 7.

I'm building a Gordon Anderson Microstar 2000 encoder and was originally going to fit it into a Kraft Tx, but the fit is fairly tight and the open Gimbal Kraft sticks just aren't as good as the Chidgey sticks were. The ProLine was taller and everything ought to fit better. I can make the Kraft conversion work, but the ProLine approach is much more appealing. Anyone know of a source for one?
