The main problem was that the two batteries were unlinked, which caused drawdown in the main battery, also resulting in the charging system to be inoperable. I suspect this prevented the ECU from get...

@darrahc Nothing to update on progress and problem still persists. I have had to take a break from diagnosis because of my busy race schedule, however I will update the thread once I have more infor...

With the help from some friends at Radical I just updated the latest Revision to the "Identifying Radical Model Years By Chassis Number" Guide. The latest version shows the start of the 2022 model ye...

@davidf - regarding your comment "On a different but related topic, I use a 3/8 inch size 19mm non-impact socket (made by Gearwrench) to remove the reverse sensor and and index plunger/detent when dis...

David; I am curious about your 20hr axle tripod grease R&R comment above. My manual says every 10hr, which I have been doing, but seems excessive as grease still in like new condition. On a sid...

@slip_angle The SR10 has been an absolute blast. The open cockpit is a whole new experience. I started with the regular exhaust but then quickly moved to the quiet exhaust so I could pass the 105 db...

I don't strap down the fronts either. Just the rear, similar to the photoshopped photo above. Now then: you need an enclosed trailer. 20 feet is plenty, and then you can put some cabinets in the front...

Welcome Clark. It is a small world. I live in Tennessee but I am also a member of VIR and I know Danyel and his team well. I also have a steep driveway from the street. A couple of 2x10s and wood b...

Hi @darrahc, your overall set up looks good but as Rod mentioned you will have to adjust the location a bit. The center of gravity for these cars is just behind the roll bar. When trailering you wil...
