plan on planting corn this year. I ordered small to medium rounds like the manual said. The seed dealer called and said my seed is in. The seed he ordered came as large flats? And one have any experience planting flats with plates that state small medium rounds? Any suggestions? Thank you

ANY air planter prefers ROUND seeds not flats. So, right off the bat you aren't right. Thee most common corn seed plates used on AC and DA air planters was the MEDIUM disc or SMALL MEDIUM size disc and the customer used medium round seed. I've never used LARGE or SMALL discs. Without seeing your seed laid in your seed disc pockets it is hard to say, but I feel it won't work well. Probably have many skips.

I'd say to take a look at the seed before you jump to conclusions. I hope that you can make it work. Darrel

Lay the disc flat on a table and spread out some seed into the pockets and see what it looks like. Pretty much the seed better be 80-90% inside the pocket. You'll then see why flats are a poor choice.

The issue with flats is it takes more air pressure to hold them in - at least 2 WC". The air system is very forgiving IF you have the pressure. Tricks like a hot alternator putting out 14 V and pulling off that as on is supposed to - make sure the voltage is the SAME at the motor as it is at the source. Bad switched, connectors etc will drop volts when the amp draw goes up. We found grounding the negative wire by stripping it back and adding a wire ground from there to the motor base will increase motor speed. Make sure the squirrel cage blades are cleans and turning in the correct rotation. I found an air system off a White planter worked great- they are adjustable. I installed the short cut off pads and tickler brushes off a White (same as the milo kit on the 385) added a tad more air pressure to eliminate skips and the ticklers wiped off the doubles.

Nickia, Here’s a PAMI (canadian) evaluation publication weblink that contains a brief overview of different corn seed sizes per 26,500 ppa per 2 seed pads within the AC Air Champ units. According to its findings, the large flat corn seed was in the 90% singulation per their 0.5-1.5” deviation?
In addition to DrAllis & Tbran’s excellent advise, try doing your own planter’s seed meter test run using the large flat corn seed. Often a cordless drill hooked up direct to a seed meter or to planter’s hex drive shaft driving only one seed meter can assist approximate seed meter speeds while adjusting different air pressures, seed singulation brush/tickler, seed discs, etc so operator can observe first hand if seed singulation is acceptable or not?
5mph seemed to be the Air Champs preferred speed?
