@cwrega The "NoRTC" is highlighted in blue at the very top of your screenshot. Charley is dead on about the battery. I had mine replaced after it died but I know others just use the Aim Studio 3 soft...

I pull mine with an open trailer and have never had an issue. I have an air dam on the front of my trailer so that may help offset the impact of the rear wing. I figured if there was going to be an ...

This was a very useful post. I had the same problem with trying to get data from the ECU and thought it was some kind of bug with my computer, connections, drivers, etc. but it ended up being a dead ...

This is an ongoing issue for me and I have no idea why. A few weeks ago I had to send my ECU back to Radical to replace the battery. Apparently if you don't start the car every so often, the battery...

Awesome write up! And love the homemade tool idea. I've found that about 70g of grease works a lot better than the recommended 100g in the SR10 manual.

I reached out to Hewland for torque values on the gearbox since Radical doesn't have them in their manual. Here is the picture I sent Attachment : Gearbox Picture.jpg And here are the values: ...

You could try reaching out to Jonathan Scarallo at Group A Racing. He just tried to sell a really well sorted SR3XX on BAT, was super engaged with the listing and came up short. As Charley said, it ...

@parsonsj I kind of surprised to see the guy had chased the Bimmer all the way up to Oak Tree. Usually they're off in the grass on the right or in the Armco on the left. That is not a good corner to...

Nice lap at VIR and it looked like you pretty much had the track to yourself. I've thought about running with NASA - maybe later in the year.

That's awesome to have the factory engaged!

My tires look almost exactly like yours in terms wear and I've used them for about 20 cycles. I just use my car for track days and don't race so they've been fine. Right now, the limiting factor to ...

My tinkering is limited to routine maintenance. Unfortunately (or probably fortunately) I have a pretty good idea of what's beyond my skill set and try to stay under that threshold even though I woul...

Hi David, Yes, I did. I called them and they had a BT429 but weren’t sure so I sent them pictures and measurements of the Radical boot. Haven’t heard anything back. I talked to Danyel at WISKO and he...

@rojid congrats on a successful outing! I know it's been a long road of learning - I'm on the same road!

Anyone know of a good (quick) replacement for drive shaft boots? I was repacking mine and have two that are torn. Radical posted a technical bulletin about these having manufacturing defects a few m...
