Jeff Lutz said:

Mark, on the entry it has A hydro and B hydro separately. But just curious, does the rule book allow this? Or is it clubs allowing it?

Rick, does the 8 boat minimum apply to just the heat racing portion or for all the events?

If a class does not get 8 entries and the SAW and Oval are canceled, will the SAW and Oval entry fees be refunded (or maybe turned into raffle tix)?

Entries Open June 25, 2024 on RCRacingEvents.com!

IMPBA's District 5 has hosted more International Regattas (Internats) than any other site in the country. There has been a total of 39 IMPBA Internats and Huntsville has hosted 9 of them. The first full Internats was held in 1972 in Flint Michigan, but the only trophy presented was the Excellence of Performance won by Lenny Skwiera. Lenny, Bill LeFeber and others then worked out the US-1 format and The Indy Model Boaters hosted the first US-1 event in 1975. There were only seven US-1 classes that year. However, the event built a large following and in the years since grew to 18 classes in 2022.

In 2024, we are offering the “Original” US-1 format as it offers the best challenges of both worlds.

For those who have never participated, The IMPBA US-1 Internats is a combination of Straight Line time trials, Two-Lap Oval time trials, and Heat Racing.

The first event is 1/16 mile Straight Away timed trials. In that event, an individual races a boat through two electronic timers with left-to-right/right-to-left passes attempting to be the fastest in the class.

The second event is the 1/3 mile Two-Lap Oval timed trials. In this event the individual races two laps around the buoys through the electronic timers attempting to be the fastest in the class.

These two events comprise the Trophy Trials, but new IMPBA records can be set!

The next event is National Championship Heat Racing. This event is 4 days of heat racing with specific classes on specific days. This allows the racers that just want to compete for a National Championship to enjoy some of the best heat racing that can be offered.

What does it take to be US 1 Champion?

A racer must enter the Trophy Trials and the National Champion Heat Racing events to qualify.

The Straight Away and Two-Lap Oval Trophy Trials event will account for 50% of your score. The National Championship Heat Racing will account for the other 50% of your score. These scores combined define the US-1 winners. Winning US 1 will tell everyone around the world that you were the best for that year!

Can a racer be US 1 in heat racing only?

Yes, they can, but you must be entered in both the Trophy Trials and National Champion Heat Racing events to qualify. It is hard to do but it has been done!

There will be a minimum of 8 boats required to make a US-1 class.

One of the special trophies that will be presented is the Excellence of Performance Trophy. This trophy is IMPBA’s highest honor and uses a weighted score system to calculate the winner based on the number of entries for a given US-1 class.

The next special award is the President’s Cup Trophy for the best single performance of 2 boats based on heat racing only.

The final award is the William E. LeFeber award for outstanding sportsmanship and service to the organization.
