    For the power on the drag we have a 90 amp bulldog on each lane with a capacitor, the trap we will have to figure out what works best.
    The oval and kingleman will have one supply for four lanes.
    We would like to get some races going asap but we will have to see how much interest we have from racers.
    The last track is getting its paint this week, we have 4k feet of braid waiting to get laid.
    The tracks were using the old SRT timing system, we have a couple of lapmater systems on the way to replace the old system, the strip has trackmate timing.

    Tom – the Shutdown and trap area are important and tricky.  Alot of damage can occur to cars if the shutdown does not slow the cars and if the trap allows cars to fall on the floor.
    If you are running glue the combination of the glue (heavier than the light glue used on the running surface) and shorted-rails provide braking. If you are Not using glue you may need to consider embedding block magnets (available from HaborFreight for 99c a pair) into routed holes in the wood next to the rails. These slow the cars by attracting the motor can and any steel in the chassis. Based on my experience you will need several pairs of magnets 5 to 10 pairs per lane spaced about 3-inches apart from the previous pair. #97505, #98406

    Since you ran out of room for a “bag/net” you may need to experiment with a ‘box’ made out of foam, such as used for pool floats (small life jackets and boxing practice helmets). The purpose of the box is to prevent cars from bouncing out onto the floor.

    So, last weekend 4/7/19 Capitol had a run-what-ya-brung race organized by a local 1/24 fan. It was announced on the Facebook page and the regional slot car board (slotcars.net). Appx 10-12 racers showed up; after test and tune qualifying ran up close to 5pm (normally closing time), then 8 intense 5 minute heats. The rack seems more stable than a few weeks ago, not sure if they added more glue or straightened out the hairpin; altho there were still several de-slots in the inside hairpin. Wings and door-stops with high fins were the preferred cars. Best laps were all in the upper 3s (3.8-9). The counter has new product, and Chris is in process of repairing several rental cars and controllers. They also have a sorely needed pack of Parma lane stickers, but need to post a standard rotation.
    The drag strip is operational. The only 2 reasons I can guess as to why the tree is so far down the track are (1) it’s position is less distracting to the wing/road racers, (2) it’s distance makes it extremely hard to see the guy in the next lane via peripheral vision (i.e. a good result). Working out the gluing strategy seems to be a work-in-progress.
    The driver-stations I thought they were going to add are still not installed; I have cobbled together a hanging tray for my controller and an extended XLR to gator adaptor with extra large clips to fit the rectangular u-bolts.  They claim a website is up but all I can find is the board: http://slotcars.net/forum/viewforum.php?f=32

    Fresh cars! New blue LMP with aluminum chassis with new Hawk-7 (48k) motor; has ran a very smooth 100+ laps. Corrected red wing car with Phoenix (extremely high torque, RPM > 50k) motor, new drivertain (original was all FUBAR by assembler), fresh tires & guide. In process of the “art” of weight tuning both!

    My original purple LMP was 2nd in the concours back in June – but she’s a little porky and the best she did was 3rd in a race in July (lots of luck involved there!)  As of 2 weeks ago the motor is end of life and chassis is being re-purposed for a NASCAR-truck (with a fresh Hawk-7 and complete re-build – guide, wires, drivetrain, tires/wheels).

    CONTROLLER TUNING – With my fresh cars (totally new or with new Hawk-7 motors) my lap count and times improved, but there were still some tricky corners where a de-slot was always a high-risk, esp. in the Hairpin and leading into the Donut.  When my finger was a little “too early” after a turn- a power-out (wheelie) would occur.

    A major factor is the relatively Low braking-force of the Hawk-7 – it has high RPMs (48k) but spins like a Slot.IT orange-bell (not much torque/magnet force)  [in contrast- a Phoenix has so much torque that if you clean/glue the tires too forcefully the pinion will bite corners off the Spur!]

    A few months back I was having inconsistent results from my DeFalco controller, even after experimenting with different resistor packs (e.g. 180, 220 -vs- the 280ohm used on the ASCC track).  I had smoother results overall with a Koford 3-ohm controller with a simple brake pot (no pulsing circuit).  However, with the faster motors and lighter chassis there was simply so little braking (esp. during a Yellow/Track-call) that control in the most tricky corners was always a gamble.

    So recently I dusted off the DeFalco and played again with the chips – settled on the 220. VIOLA! Wow!  I now had smooth and reliable braking in the worst corners, dropped at least 0.2 sec lap times and placed at least 2 places up than average in two different classes (GTP, LMP).
