It’s about reaction time

From: Mike Roberts


For SEN please.

I could be wrong (not possible you say), but I believe both Ed’s proposal and the previous proposal from Larisa and Artem, are trying to eliminate the “variable speed” thumb issue when timing F1 Cs. I have been using electronic timers for eight or nine years now and have at times experienced scored engine times that varied by three tenths of a second during a seven round event with no change to the engine program. Given that one one hundredth wrong can eliminate a competitor, it would be wonderful to not have to worry about this possibility.

Perhaps, after the timer reviews the program and does a ground check, the timer could hold the flyers programmer until after launch, thus eliminating the possibility of an “adjustment “ to the engine run time. I do hope that in the near future we may have certified chips or something that we can install prior to the first round of our contests that give us a legal engine run without having to struggle to determine engine stop with a stopwatch.

I am an active F1 C flyer with many years of electronic timer experience.

Just another free opinion.

Best Regards
