I don't like the term apologist, but I would like to think that I have been a pretty staunch supporter of IMAC since I got into it 5ish years ago.
This past weekend I attended my first pattern contest, using a borrowed 3d plane, competing in advanced. I literally flew the sequence (and the plane) twice the morning of the contest. Below are my thoughts as they relate to IMAC. Hopefully this doesn't devolve into a pooshow.
To start with something that's probably a known thing, but this being my first actual hands on experience with it, Peter Vogel's scoring system is freaking amazing, and frankly I have very little desire to use the traditional paper system with or without a scribe (which could be another topic in and of itself) Having the maneuver's directly in your ear was great, there was truly never a reason to take your eyes off the airplane.
1A. I was lucky enough to meet Peter as he was competing at the contest and was able to discuss some things with him. I know cost has been the big issue for IMAC, but as I understand, he actually takes a loss on the systems, and there are ways to decrease the cost, i.e donations of monitors and printers. He also mentioned that not all regions have multiple systems, it depends on the geographical size and population of the region, which makes sense.
1B. the live scoring is phenomenal, and the reality it takes a significant burden off of the scorekeeper and runner, not to mention that scribes aren't needed and every contest I've ever been to has issues finding enough scribes. It also provides the contestant with near instantaneous printouts of their score, which for overly competitive folks like me is ideal.
1C. Dealing with unknowns wouldn't be an issue as you would literally type in what you want the system to say, which can be done fairly quickly once the unknowns are distributed I think
In the non FAI class, the maneuvers are much simpler, and the scores reflect that, it's kind of easy to see why they are precision aerobatics and we're scale aerobatics. With simpler maneuvers the focus is truly on doing them perfectly as opposed to just getting through them.
Take offs and landings are scored, which I love. Quite frankly watching some people try to take off and land their giant scale planes in even the middle classes is a damned terrifying experience. I think if they were scored in IMAC then people would actually practice them. To fight off the easy argument, crashing is as/more expensive with the composite pattern planes as with giant scale, and frankly if you can't takeoff and land safely chances are that your control of the aircraft is not all there, even during the sequence. The highest class FAI or unlimited in our world don't have takeoffs and landings scored which i think is fine. "But A.J.! takeoff and landing aren't judged in IAC!" Sure but in getting their pilots licence they have proved they can takeoff and land, IMAC pilots have not, and we do figures with elements on them that would be impossible in IAC, so while we are based on IAC we aren't... The downside is that the next pilot has to wait to take off, no holding pattern etc. which leads to my next point.
Which is better? 1 19 maneuver sequence including takeoff and landing or 2 10's? For electrics that's probably a pretty obvious answer but for gas probably less so. At this particular contest there were 30ish people, doing the AMA classes, plus classic pattern and edf sequence (classic and edf flew 2 rounds at the beginning of each day and added about an hour and a half to each day) The AMA classes flew 6 rounds or 114 figures each including the scored takeoff and landing. A typical contest in the southwest is 3 double sequence knowns plus an unknown or 70 scored figures each pilot. a smaller contest would fly more rounds, but I imagine the same would be the case in pattern. There has been some discussion in IMAC about a single 15ish maneuver sequence and I think that there is merit to that.
The box/centering. At this contest the judges were instructed to ignore the box for intermediate and below, which I thought was kind of cool. I think a 60 degree box is too small for IMAC but a 75 degree box may have some merit. Box argument aside I think the emphasis on centering is great. It forces the pilot to pre-plan maneuvers a little better, and respect the wind etc. or take a deduction. Having a box or at least an emphasis on centering would eliminate the need for the incredibly subjective and often curiously judged airspace control score.
Some things that I like better about IMAC, I was put under the impression that wind related bobbles were a deduction in pattern where they are not in IMAC. IMAC wins on that for sure, as I think deducting for something out of the pilots control is big dumb. Our planes look a hell of a lot better in my opinion. I am still pro-unknowns, and not having them was noticeable, although I did like having the ability to fly on Saturday and not having to worry about learning them.
Obviously I will still be flying IMAC BUT i will say I'm definitely going to start flying some pattern as well, in addition to making me I think a better IMAC pilot, there are for sure some things that I feel pattern currently does better. Apologies for the extremely long post and if you've made it this far thanks! If I think of more things i'll add them to this thread in a fresh post. Hopefully this stays professional and mature, and leads to productive dialogue.
