Drift Expo Sofia brought four days of RC drift to a drone expo, and a driver's thank-you asks for more

The expo's programme gives the shape of the week. Tuesday 6 and Wednesday 7 October were open driving, team sessions, a parking challenge and games; Thursday 8 October ended with an hour of qualifying runs; Friday 9 October had elimination battles for a top 32 from 13:45 to 16:00, then the prize-giving. The club's page on the expo site describes its competitions as individual qualifying followed by head-to-head duels.

Still not confirmed here:

• which two of those days the post means
• the surface — carpet, P-tile, polished concrete, asphalt — and therefore what anyone was running for tires
• who ran the pit and sign-up side, and whether the programme ran as printed
• how many drivers entered, in how many classes, and whether the top-32 bracket filled
• whether a spec tire or class rules applied
• results, including any placings
• whether another edition is planned

A post thanking organizers does not tell us how many people stood at the driver's stand, and we are not going to read a turnout out of the word "awesome." If you ran the event, or drove at it, the record is thin enough that a single follow-up post with the layout, the rules and the finishing order would be the event's history.

If a second Drift Expo Sofia happens, these are the details that decide whether someone with a 1/10 RWD chassis in a bag can turn up and drive. Most of them are not settled in anything published about this event; they are the things to ask an organizer before building toward a rule.

Surface and tires

Surface decides the car. A carpet setup and an asphalt setup are different whole configurations — tire, ride height, spring and gyro gain all move — and the tire itself is hard plastic matched to the floor, not a compound you heat. Many events also mandate a spec tire so nobody buys grip, which is the single most useful line in any event flyer.

Classes and drivetrain

RWD is the modern standard, and most entry lists are written around it; AWD and entry-level classes exist at some events and not at others. An event's own rules are the only authority on what is allowed to roll out.

How runs are scored

Where RC events do run a tandem format, the pattern is the one borrowed from full-size drift judging: each driver leads one run and chases one, the lead car drives the judged line and clipping points, and the chase car is scored on matching that line with angle and proximity. The expo's programme put an hour of qualifying runs on the Thursday and a top-32 elimination bracket on the Friday, so this one was set up to be judged; who judged, and on what criteria, is not stated.

The post is on r/rcdrift: Drift Expo Sofia by u/Bobaka6taka, October 10, 2026, and the longer cut is RC Drift Expo Sofia 2026 on Boris' RCs. The schedule is on Inter Drone Expo's programme page. If more attendees post photos of the layout or the finishing order, that thread is where the rest of this report will come from, and we would rather update it with their words than guess ahead of them.
