Maxfliart has a brilliant way to find lost freeflight rubber powered planes in corn... We can use it too...

It works...if you can see the bearing where the object went into the corn, you have an "anchor point" (a table in this case) as a starting reference....and you are actually in a position to see the corn field, and a buddy willing to help out.

Rockets in corn suck, most people dont realize that corn is either wet or dry (depending on irrigation or season or both), if its wet, well so are you before long, if its dry the leaves can be sharp and brutal, corn is also planted extremely close together, wear long pants, long sleeves, a hat, glasses and good shoes its never pleasant in a cornfield.

Best way to recover a rocket in a corn field is tracking it via GPS....invest in a good one and our electronics vendors make some fantastic options.

BTW if you ever fly TCR's field, there is a corn field over the hill to the northeast people never realize is there until its too late, a main opening at apogee by accident with our usual prevailing winds puts rockets into it at least once per launch, and at SodBlaster with over 600 flights over 4 days maybe a dozen rockets went in and only about half came out afaik.

All corn deserves to be cut down and eventually eaten. Serves them right...

Funny thing about cornfields is, we check them after they are harvested and never find bits of rocket...ever, the damn corn must eat lost rockets afaict...

Nothing beats an Eggfinder if you are lost in the corn.

GPS is great but if you want to find your rocket for far less money, The Marco Polo Drone/Rocket tracker does just as well. I am 12 for 12 on soybean and corn recoveries. Pretty much everyone in my local club has one and it has not let us down. Even used it on my L3. Photos below!

One of my clubs flies at a field that sometimes has corn planted nearby. I’ve never landed in it, but the advice I have received is that it helps to have a “screamer” — some kind of loud siren thingy.

Thank you very kindly for the information. It looks like a cool system. However I don't want to build it nor have to use another android device to use it or carry a laptop in the field. The other option requires an fcc technician license. Dont know if this is a valid comparison. If they had a complete system that did not require yet another device or a license then I would be interested. In this case too, I don't want to build it either. I like the system I have as it is ready to use right out of the box. Thanks though!
No Cell phone required- uses the LCD receiver. Add LCD Rx GPS module and you have a independent GPS locator system.

As Teepot stated, "MCTronics is assembling it. His prices are inexpensive for assembly. "

Our club field has the 8 foot tall corn from July through October. GPS not best for locating since one needs to be very close to see the rocket (see above photos in this thread).
A Screamer is good since one can typically get within a few dozen feet of the rocket.
I have built and been using Ham band 2m RF beacon TX's then a Handy talkie to do RDF. Works quite well to walk me right to my rocket.

It's a good product, but the limitation is range - only 2 miles. I saw an L2 flight last year that would have been right at the limit of that range. You have to realize that while ground wind speeds may be nominal, wind speeds at altitude can be much faster. I've saw another 10,000' flight land this year farther away than that because the wind speeds at from 3000' to 10,000' were over 40 MPH. We never saw the chute at all; it had drifted so far that we were all looking at the wrong section of sky. You'll still drift a long way on a drogue at those speeds. As much as I spend on the rocket and other electronics, I do not want to lose a bird because I landed outside the tracker range. A few extra bucks are worth it.

Getting a basic ham license is very easy these days. It's not like you have to know morse code like in the old days. There I go, dating myself again.

A corn-field next to a club launch site....its verging on a rite of passage thing!

My 3inch AGM33 lawn darted into a full grown corn field. I must have walked past it multiple times. Eventually the pet tracker signal kicked back in next day so was able to close in on it and dig it out.

Same field ate my first love (an Estes V2)...before I used electronics. Never saw it again.

Thanks I am fully aware of winds aloft. We had a 10,000 foot + flight in our club that landed almost two miles a away. He had both GPS and a Marco Polo. He completely lost sight of it. Seems his GPS failed to retain a lock on the signal. After a number of hours it was the Marco Polo that saved the day and it was found with this device. MP has a TWO week battery life on the tag. When he returned to the field I was sold on this product. I used it in my L3 that went close to 10,000 feet and landed very far away and out of sight for a time. It took me right to it. Also as a drone tracker, they are designed to track fly away drones, meaning they crash far away.

GPS is indeed wonderful. But many just want to purchase and fly their electronics and not build or get other items like 3d printed boxes, or use android devices. I also, like many don't want to utilize a license option. Just want to order it, open it and use it (when it comes to electronics).

I think it's best to use gps or a tracker. Sometimes a rocket can go into the corn . . . . . . and then move.

I've heard of corn snakes and land sharks... I think you combined the two there and got yourself a Corn Shark

In a similar vein.., Flying from parks is nice. Someone keeps the grass cut, there is parking and often facilities. However, often rockets drift into nearby residential neighborhoods. Kids will steal free rockets, Adults may bring it inside and start preparing to use that return address, unaware that you need a contest return that day. You need to chase down and and recover models promptly.
