The former heavyweight champion has been eager to take part in a challenge since the first show, but this will be his first time facing a trial.
Since Monday, the campers themselves have been deciding which of them will face the daily tasks for food, with Ashley Roberts taking on the Terror Train last night.
Tonight will see David take on the Scare Plane, an "amazing" trial which will see David hoisted high into the jungle canopy.
"It's very, very scary," teased the show's bush tucker trial boss.
David will be 'flying' one plane before having to exit midair and jump onto a second plane over 100 feet above the jungle.
Balancing on the plane's wings, David will have to search the planes for stars, and of course there will be plenty of critters joining David in the air.
But that's not all, the trial will end with a leap of faith if David wants to bring the stars he's collected back to camp!
