Are the aircrafts themselves actually judged during an IMAC event? I watched a special on the Top Gun competition, and those were judged on both the aircraft and performance. Is this the same with IMAC?
Or is all that is required is that the plane be within 10% scale version of a real plane?
I also looked at a score sheet on IMAC webpage, and there was a box for sound. Is the sound of the plane also judged?
In IMAC only the sequence being flown is judged. IMAC is all about the pilot but having a properly setup and trimmed plane certainly helps a lot.
Yes, sound is judged as well. Here is the current rule
These boxes shall translate in the computer to a score of: Too Noisy - 0, Acceptable â€“ 5, Very Quiet - 10. This score will then be multiplied by the K value for the individual class. If two judges are utilized, both judgesâ€˜ scores must concur to issue a Too Noisy penalty or a Very Quiet bonus. In absence of a Too Noisy or Very Quietâ€– concurrence, an Acceptable will be scored for each sequence flown. If three or more judges are utilized, a simple majority concurrence will issue a Too Noisy penalty or Very Quiet bonus. All Pilots that receive a Too Noisy penalty shall be notified of the penalty by the Contest Director prior to the next round. Pilots that receive a Too Noisy penalty will be allowed to adjust the aircraft setup and fly the next round (Known Unknown). Any pilot, who receives a second Too Noisy penalty during any Known, or Unknown, will be disqualified from further competition at that contest.
Now it's quite possible to have a plane with a 2-blade prop and standard mufflers and be judged as acceptable using good throttle management
As far as the 10% rule, that does not apply to the Basic class, only Sportsman and above and then the full scale version of the plane must have flown in a full scale competition at least once. I've never run into a CD (Contest Director) that actually goes through and measures every plane we typically use. In some cases, some of the planes we all fly that are scale representations are not exactly 10% and in some cases are no where near 10%. Sportsman and above is required to have a pilot and dash installed. The pilot is required to be of human form but the dash can be a simple printout from a web site of a dash. I've seen contests won and lost over the 1% penalty that not having the pilot/dash installed
Basic, is a "bring and fly what you got" type of class (introductory class) so in that respect it's quite a bit more lenient and I've seen 40 size Stik's being used and taking 3rd or even better is some cases. The other area for Basic that's different is that they do not fly an unknown sequence. When everyone else is flying their respective unknown, they get to fly one sequence of their known
Top Gun is completely different and if you can ever get there to see it, go, you will see some incredible work.
