Thanksgiving Turkey Pie Drop

Hi everybody! We had a great response to our last video. Lots of you voted on what Mr. T should wear for Thanksgiving. Well, your prayers have been answered! By popular demand, here is a video of a giant, quadcopter, flying turkey cyborg that drops pies!

Some of you will notice that this is not, in fact, Mr. T, but is instead his evil associate, Professor X! This is the quadcopter that does most of our shooting. It's tough, flies well, and can take a whole lot of abuse. It's based on the KKMulticopter flight control board (just like Mr. T, it is also programmed with a Sparkfun Pocket AVR Programmer) this system has proven to be very reliable, though it does lack some of the more advanced features of our Arducopter and Mikrokopter based aircraft.

This is the turkey, just before we added some finishing details. It is constructed of four long sheets of poster-board for the cylinder, and smaller pieces for the head, wings, and tail with some small parts that are folded over for strength. The cylinder is lifted by straightened coat hangers that are zip-tied to the quadcopter's arms. There is also coat hanger around the inside of the cylinder and the tail (not visible here) to give them strength. Without it, the props suck them in! (Experience!) The entire setup is actually pretty balanced.
Here's Scott getting ready to hand launch. We've found this to be so easy that I don't usually include landing gear on these helicopters. Of course we're careful, but the quads are far safer than conventional single rotor helicopters.

I didn't get a good photo of the dropping mechanism, but it can be seen pretty clearly in the video. It's just a piece of bent-over aluminum with a hole drilled through. An old servo controls a pin that goes through that hole, when it's pulled out, the load drops.

It actually flew surprisingly well with the turkey suit on, the pie badly unbalanced it, however, making it pretty much impossible for me to drop the pie on Scott properly.

When it was all over, we released the turkey suit into the wild, where it lives peacefully.
Thanks for reading! If you liked the video, please share it! Happy Thanksgiving everybody!

  1. I seek refuge in Allah from the accursed Satan

    Name of Allah, the Merciful


    In the day when Allah gathereth together the messengers, and saith: What was your response (from mankind)? they say: We have no knowledge. Lo! Thou, only Thou art the Knower of Things Hidden, (109) When Allah saith: O Jesus, son of Mary! Remember My favour unto thee and unto thy mother; how I strengthened thee with the holy Spirit, so that thou spakest unto mankind in the cradle as in maturity; and how I taught thee the Scripture and Wisdom and the Torah and the Gospel; and how thou didst shape of clay as it were the likeness of a bird by My permission, and didst blow upon it and it was a bird by My permission, and thou didst heal him who was born blind and the leper by My permission; and how thou didst raise the dead by My permission; and how I restrained the Children of Israel from (harming) thee when thou camest unto them with clear proofs, and those of them who disbelieved exclaimed: This is naught else than evident magic; (110) And when I inspired the disciples, (saying): Believe in Me and in My messenger, they said: We believe. Bear witness that we have surrendered (unto Thee). (111) When the disciples said: O Jesus, son of Mary! Is thy Lord able to send down for us a table spread with food from heaven? He said: Observe your duty to Allah, if ye are true believers. (112) (They said:) We wish to eat thereof, that we may satisfy our hearts and know that thou hast spoken truth to us, and that thereof we may be witnesses. (113) Jesus, son of Mary, said: O Allah, Lord of us! Send down for us a table spread with food from heaven, that it may be a feast for us, for the first of us and for the last of us, and a sign from Thee. Give us sustenance, for Thou art the Best of Sustainers. (114) Allah said: Lo! I send it down for you. And whoso disbelieveth of you afterward, him surely will I punish with a punishment wherewith I have not punished any of (My) creatures. (115) And when Allah saith: O Jesus, son of Mary! Didst thou say unto mankind: Take me and my mother for two gods beside Allah? he saith: Be glorified! It was not mine to utter that to which I had no right. If I had ever said it, then Thou wouldst have known it. Thou knowest what is in my mind, and I know not what is in Thy Mind. Lo! Thou, only Thou, art the Knower of Things Hidden? (116) I spake unto them only that which Thou commandedst me, (saying): Worship Allah, my Lord and your Lord. I was a witness of them while I dwelt among them, and when Thou tookest me Thou wast the Watcher over them. Thou art Witness over all things. (117) If Thou punish them, lo! they are Thy slaves, and if Thou forgive them (lo! they are Thy slaves). Lo! Thou, only Thou, art the Mighty, the Wise. (118) Allah saith: This is a day in which their truthfulness profiteth the truthful, for theirs are Gardens underneath which rivers flow, wherein they are secure for ever, Allah taking pleasure in them and they in Him. That is the great triumph. (119) Unto Allah belongeth the Sovereignty of the heavens and the earth and whatsoever is therein, and He is Able to do all things. (120)
