I have been playing with a new used Difalco controller and really like how you can plug in resistor networks to change the characteristics for different cars and tracks. With the controller I got the usual 148 ohm plus a 113 ohm and a 78 ohm. All linear. I got a custom kit and made up a 7x3.9 ohm, 7x3.0 ohm and 15 2.2 ohm for a total of 81.3.

 

We run a run what ya brung with the only restriction being a Hawk cobalt motor on a Hasse king. I had been running the 78 ohm but find the new custom really helps in the gutters with the sensitivity turned up maybe to 5 or so.

It is curious how the different networks react with different car/track combinations.  I stick with linear for a consistent across the wiper feel - no surprises.   The FK neos on a King and C can 12s on flat tracks both like sub-100 ohm networks.  I set the knob for full ohm for the gutters and about half for the center lanes.

I went down as low as 43.5 ohm but no matter what I did, I could never achieve the "feel" that I wanted.

 

I ended up selling my high end controller/choke to another local racer :(

I just started up racing again after a 25+ year hiatus. I raced a lot multiple times a week and most weekends back in the wing car and copious amounts of glue which was a whole different animal from wings and spray glue I race on now. Before it was mostly a timing thing with the controller being 1 ohm so more like an on off switch. Having more control helps now but it is hard to get rid of the glue muscle memory from days past. I did race the first month with my old external resistor controller and did ok but I needed more finesse.

Back in the day I raced mostly in NJ, PA and OH and up and down the east coast. used to run the old Keystone USRA series and one series that Andy Wasserman ran which I forget the name of. Ran weekly races at Zepplin, Allentown, Easton Rockaway and any other track that had races. Lots of time and money spent but learned a lot which still pertains today. Now I race at Paul Pfeiffer's Alpha raceway but he is a part time track only open in Tuesday nights for racing. The only testing and practice I get is prior to the race so I build a bunch of cars with different tweaks and see what works. But I find that doing the basics and paying attention to the details still brings rewards.

In Madison now(!)...so is Howie.  He comes to Chicago to race (two stores), and Milwaukee is even closer as well.  Minnisota has a track open again I hear.  Lots of places to race in a three hour drive.

There is the rub. 3 hour drive. When I moved to the midwest and was in the twin cities I ran a bit at the track in St. Paul. At the time they had an Englemann (which they still have) and the old king that was at Wasserman's place in the Bronx. I recognized it right away with it's hump going into the dead man. Swiss's place is maybe 2 hours without traffic. Lucky Bob is only an hour so there are places.

 

I haven't seen Howie here. I remember meeting him back in 66 or 67 at I track I raced at in NJ. I was just a kid like 6th or 7th grade. The summer of 67 saw many of the track go bye bye.

I won about $1,600 in 2 races on that King.

I thought it was fine. Lol

Did they ever get that track running in St.Paul?

When I being it up to visiting racers from that area, they act like I'm speaking Martian.

I never said it was bad just unique enough to recognize it right away. I won a few races on it as well although not the money paying kind. The place in St. Paul no longer has the king. They still have the Englemann, an oval and a drag strip. I haven't been there since maybe 1998 when they had the king up and running. I have not heard where it went.
