Pray tell, oh wise ones ...
What are the options for counting the laps - assorted goblins given snacks and a pat on the head for counting? MyLaps transponder feels a bit expensive for a first toot-around ... wife or kid not interested in trying to keep track of things. Maybe the dog? Have to ask.
I use an app called LapTracker on my phone that I found out about from an article on The RC Racer.

Sometimes getting the detection zone setup is a little finicky, but it has been pretty easy to use and has been faultless for running RBP laps.
I turn the volume up nice and loud so I can hear the lap times called out each go around.

Shared some pictures of my cars and the turnout from the vintage racing meet this last weekend.
Had lots of fun
Also saw lots of vintage cars ripping up some dirt, and a couple of the 4wd rc10s were racing. 
Hello from another Tamiya Club member in the Treasure Valley 👋
The new layout at Eagle Hills is a lot of fun and recently I spent an evening there trying to chase down some other drivers in my Hornet Evo.
One of these days I may make it out for an actual event. Looks like a solid turnout for the vintage race!

I had my first attempts at this course this weekend and once I got into a rhythm this course was a lot of fun! The joker lap adds an extra challenge, too.
Instead of the TT-01 I've been using I decided to pull out some other cars - my Egress and a TT-02 in rally spec.
The Egress drove wonderfully on the course and is shod with leftover slicks from my 2WD race buggy. They're a bit worn out, but did the job. The only issue I had with this car was the incorrect gearing. On such a tight track the SS BZ motor got ridiculously hot, so I'll have to swap pinions before attempting again.
As for the rally car, it's utterly useless and oh so fun. The setup I have on it does not translate well to high grip tracks, so driving a lap consisted of full throttle, hard on the brakes, massive slide, then full throttle out of the corner. Fun, but hard to be consistent when all 4 wheels are never pointing the same direction. It has long travel dampers so it's cool to watch it roll around and I have a Holmes Hobbies retro sport 17T motor in it. For some reason the drivetrain on this car is really loud, so it sounds like a proper rally car with a straight cut gearbox. I swap the wheels between my TT-02 and -01, but after running this car the tires are looking a bit worse off!
On all cars I'm having to fit fans as the temperatures were above 90f/32c and everything was getting hot, hot, hot.

I’ve had a few chances to run the course for this round and spent each 5 minute session trying out a setup or parts change to see how I could improve my times.
The first issue was my servo. The chassis was originally built up for spec euro truck racing, so the servo was ok, but a bit slow. I replaced it with an AGF servo that has a 0.075 transit speed and now I don’t have to turn the wheel on my transmitter way ahead of the turn. The car can now match my eyes and hands. Sort of.
Next up was the wheelbase. I have been running the Audi Quattro body, but it is meant for the longer wheelbase setting on the TT01. To shorten things up, I prepared and installed the Porsche GT3 bodyshell which allowed me to flip the rear arms and shrink the overall length. While it’s still a bit of a barge on these small courses, it did allow me to tighten up my lines.
The last change for now was the addition of turnbuckle tie rods. I wanted to add some toe out to help with corner initiation and between this change and the quick servo I am able to navigate successive corners much easier.
I have a few other items to install and try, but I’m wanting to do each piece at a time so I can understand the change and get a feel for what it is doing. Next up are the adjustable upper arms, wheels and tires, and more adjustable shocks, but for now I was focused on adding speed without overdriving the car and sliding about.
Normally I race 2WD buggy at a local indoor track, so this has been a great reason to spend time driving my on road cars in a more focused way. The closest on road track is over 6 hours away!

I recently joined the forum due in large part to this thread and wanting to participate!
You can count me in for the next round. I'll be running a TT-01E as the main car with some others mixed in for fun. I have a M-08 ready to go once I get around to ordering electronics for it. Well, and building it.-

It has been a lot of fun tuning the TT01 and slowly adjusting it to see what works and what doesn't. I had low hopes for it on these tight tracks, but continue to be really impressed with what it is capable of.
Today I finally had a chance to run this months layout and did back to back testing of some tires. Since I started participating in RBP I have been using #53227 (M2 Radial Tires). I always thought they were pretty decent - providing grip on my dusty driveway and being consistent when they broke away. Recently I've even used tire sauce to soften them up a bit, yielding a tiny bit more performance.
For my latter rounds I popped on a set of Contact pre-mount 32 shore tires. Oh. My.
The grip levels went through the roof and it turned my humble TT01 into an a track superstar. My lap times dropped by a fair margin and it was way easier to be consistent lap after lap.
I'm hoping this helps bring the ol' TT01 up in the standings for this month. Travel coming up means I won't be able to run this layout anymore, so good luck to everyone for the rest of the month! It's a fun course.
