1/24 Scale Christmas

by 2 Comments

Every year, we put some sort of motorized conveyance under the tree. In the past it’s been an HO scale train or slot cars from my childhood. While I like the nostalgia of them, let’s face it – I’m old which means they’re old. So they’re a little finicky to get working well. Still fun, but this year I wanted to try something new.

I’ve always wanted to have an indoor model train layout, but since we don’t have room I turned my thoughts to doing an outdoor layout 🤔 But that always seemed extremely expensive. Then a couple ideas came together for me: 1) my #1 Christmas gift item is a 1/24 scale crawler – Axial’s SCX24 and 2) I found a G-scale train set for less than $50.

TDK Traction Compound

by 1 Comment

On carpet tracks, the owners are very particular about what traction compound you’re allowed to use. Rightly so as the tire rubber and compound ultimately work their way into the (expensive) carpet.

On dirt and clay it’s not as regulated for club racing because it’s just dirt! This has unintended consequences… One popular “tire sauce” is liquid wrench. You can even find it listed on the pros setup sheets. While I admire the inventiveness, take a look at the Material Safety Data Sheet (MSDS). With warnings like Use only outdoors or in a well-ventilated area and Causes skin irritation, it makes you wonder if there’s a better way.

When using liquid wrench I would wear nitrile gloves to make sure it’s not soaking into my skin. Wearing gloves for tire chemical treatment is generally a good idea, but if I can also avoid irritating fumes, even better.

2WD “Backslash” Wing

by Leave a Comment

What’s a Backslash, besides this: “\”? It’s a nickname for a RC buggy made from the chassis of a Traxxas Slash. Some people call it a Backslash, some people call it a Sluggy (Slash + Buggy). Whatever you call it, the original 4WD variation is the most popular because it’s extremely simple to mount an 1/8 scale wing to the shock tower and change the body to a 1/8 scale buggy one.

I wanted to do one for my 2WD Slash. There are a couple of extra hurdles on the 2WD, like the gearbox being behind the shock tower, but it still seemed do-able. So here is what I did to mount an 1/8 scale wing to my 2WD Slash.

HobbyMate AIO FVP Camera on a LaTrax Prerunner

by Leave a Comment

I picked up a HobbyMate HB298T AIO FPV Camera for my Tiny Whoop. It’s discontinued, which is a shame, but you might be able to find them on eBay. I got it because of this very specific feature most micro-FPV cameras don’t have: Built-in Microphone.

BUT… I haven’t installed the addition to my FPV goggles that will allow me to receive and record sound yet. Video however is working nicely and I look forward to adding audio to the mix.

Flysky Noble NB4 – A great left handed transmitter

by 2 Comments

Disclaimer: I am not left handed, but this is a great transmitter whether you’re left or right handed…

During quarantine I played VRC at least once a week to get my racing fix since all of the tracks were closed. My daughter would often ask if she could try racing as she watched me play. But converting my Spektrum DX3R to left handed operation meant taking it apart to move all the components to the left.

I’d been eyeing a Flysky Noble NB4 because it’s a pro-level low latency transmitter, and it’s killer feature is that it can instantly switch from right to left-handed operation.

Since I wasn’t getting to the track anytime soon, I sold my DX3R and ordered a Noble NB4 with some extra receivers. This write-up will go through some of the features and how I set it up because there are a few things you’ll want to consider.

VRC Live Server Setup

by Leave a Comment

There are several great resources out there for setting up a gaming server on Microsoft Azure. This one is specifically for VirtualRC the R/C racing simulator.

If you want to host a race and participate in the race itself, you’ll need two VRC accounts (and possibly paid subscriptions): one for you and one for the race host. You can host a race with a free VRC account, but you’ll be limited to the free tracks and cars – that’s OK too – you’ll surely get a lot of people joining your server if you’re hosting races on the free-to-play tracks.

But if you want the most flexibility and variety, you’ll need to have the full all-inclusive subscription on your VRC account(s).
