User:Donnie Park/1991 IFMAR 1:10 Electric Off-Road World Championship

The 1991 Kyosho/Trinity IFMAR 1:10 Electric Off-Road World Championship was the 4th edition of the biennial IFMAR 1:10 Electric Off-Road World Championship for 1:10 scale radio-controlled electric off-road buggies sanctioned by the International Federation of Model Auto Racing (IFMAR) to be run over two separate classes (2WD and 4WD) over eight days on 4th through 11 August with each class running for three days each in total.

The national sanctional body, Remotely Operated Auto Racers (ROAR) acted as the host nation with the Detroit based Team SEMROCC Racing acting as the host club for the championship taking place at the Freedom Hill Park in Sterling Heights in the Michigan for the sixth time in its history and its second time as an 1:10 off-road race, the first since the inaugural Off-Road Worlds.

A-main, leg 1
At the 1991 IFMAR Worlds, in the 2WD class, Team Associated had just finished an entirely new RC10 just weeks before they were to compete, leaving them with little time to prepare. 16 cars were built Following a poor performance in practice with two practice days remaining, Lett split the team to into groups of three and fours. One focused on development to the front end, one at the rear end, one to the tires, etc. This plan paid off as Masami Hirosaka eventually won his second 2WD IFMAR Worlds.

A-main, leg 1
In the 4WD class, Lett qualified his Yokomo YZ-10 in 6th despite losing his fastest qualifying time as a penalty for failing to marshal a round following his as required. At the first leg of the A-main, he fought out with Hirosaka, who maintained the lead for the rest of the five minutes rounds until he made an error, allowing Lett to take the win. In the second leg, as Hirosaka made mistakes which left him to finish 4th, reducing his chance of being the championship contender, Lett attempted to fend off the Kyosho Lazer ZX-R of Jack Johnson but at the seventh lap, Lett rolled his car enabling Johnson to pass. Lett made up the pace but it wasn't enough for him to take the lead, settling for a 2nd-place finish. In the final leg, Lett needed to finish 3rd or above to secure the title. After an error by Johnson, this left Lett and Hirosaka to become only contenders remaining. With the worst points deducted from each driver's final score, this left the pair to tie, therefore their lowest score was used to break the tie. Because of Hirosaka's 5th-place finish in the 2nd leg to Lett's 2nd place, the latter was declared the champion.
