ULD (EPP) Precision Aerobatic Trainer

Precision Aerobatic Trainer “ULD”. It won’t get beat up in the schoolyard

Budget RC incorporated EPP and Depron to create an airplane that can flex on the ground and be stiff in the air. Using low cost electronics you will learn to Roll, Loop, Hover, Spin, Roll in Circles and basically really impress all that watch. Use it to learn new maneuvers to prevent busting up that larger scale model. Sport flyers will love the easy and stable flight characteristics, while really improving their flying skills. If you’ve been wanting to enhance your rudder skills, ULD is perfect.

The Budget RC ULD is an aerobatic trainer specifically designed to handle all the bumps and bruises associated with learning to fly precision maneuvers. It's foamie construction has been specifically designed to fly precision while being flexible enough to handle mishaps with the ground. Months of testing have developed the lightest and strongest airframe of EPP and Depron. Sport flyers will find the ULD a joy to fly and will definitely improve their skill using a rudder.

ULD is a neutral airplane and benefits by using the rudder which can easily be programed in your radio, if you choose. ULD's rolls are straight and true, and the knife edge flight is unbelievable. It is so well balanced it will do hands off knife edge. ULD WILL improve your Roll, Harrier, Knife edge, and Hover Skills (again and again) without destroying the airplane.

The ULD is also perfect for sport flyers looking to bore holes and tie knots in the sky. It has been designed to use a low cost brushless motor, while maintaining blistering performance. This kit comes packed full of carbon and includes all control horns and linkage. All parts are laser cut to perfection. You'll agree, this is the best value in 3D aerobatic RC.
