Description

The Hacker Model MadBull combines the familiar appearance and stability of a high-wing sport aircraft with the control authority required for serious 3D aerobatics. Its lightweight EPP airframe, independently controlled ailerons, and nearly ±90-degree full-flying stabilizer create a wide flight envelope ranging from smooth slow flight to extreme pitch maneuvers. Oversized soft EPP wheels make takeoffs and landings practical on indoor floors and rougher outdoor surfaces.

MadBull is so worth it!

Posted by Bill Griggs on Apr 6th 2025

I saw a video of the MadBull and decided to try one. Best Money I spent. When the CG is moved back it flies nice and slow in the Gym. Had it outdoors in 9mph winds and it handled exactly like a 3D plane should, but can do some things other 3D planes can't.

Fantastic 3D Highwing Foamie

Posted by Alex Gelina (Hangar14RC) on Dec 5th 2024

This plane really impressed me! With it being a high wing plane you wouldn't expect it to be able to do what it does. It's super maneuverable and with the dual aileron servos you can have some fun with flap mixes. Definitely a fun one to switch things up.
