Don’t be intimidated by the Dual Ace’s twin-engine configuration. Put it through its paces and see for yourself how much fun a twin can be. Even if you’ve never flown one before, you’ll discover that the Dual Ace is the perfect introduction to twin-engine models.
You aren’t likely to find a twin-engine ARF at a comparable price that flies as great as the fully aerobatic Dual Ace. Just pop a pair of your favorite glow engines into this plane, and enjoy its powerful, smooth flight. It looks great too. It’s made from the same type of balsa and plywood found in higher-market ARF’s. A colorful Hangar 9® UltraCote® scheme and fiberglass nacelles, tail and nose cones give it a top-flight appearance certain to be appreciated by the guys at the flying field.
Don’t worry about an engine quitting on you mid-flight. The Dual Ace’s stable flight characteristics will allow you to safely land the plane on a single engine.
For the best performance, install two Evolution® .46NT 2-strokes into the easy-to-access fiberglass engine nacelles.

I found it easiest to mount the nacelle by first cutting the engine openings as stated in the manual, then I installed the bottom half of the nacelle with 2 screws on the wing, one screw in one of the front screw locations on the wing and one screw in the back of the nacelle on the wing, making sure that the front of the nacelle lines up with the spinner. I then installed the plywood strap/nose ring, which holds the 2 halves together in the front of the nacelle as shown in the pictures. Then I installed the remainder of the screws in the top and bottom half of the nacelles on the wing keeping the front of the nacelle lined up with the spinner, followed by a couple screws on each side going into the ply of the motor box holding the 2 nacelle halves together. Be sure if you drill holes for the screws on the side that you do not puncture or damage your fuel tank.
The proper CG range is 80-95 mm from the leading edge of the wing at the fuselage. This is roughly 3 1/8" to 3 3/4". To achieve this CG, this model required roughly 10 ounces of weight in the front of the cowl, with the battery placed as far forward as it will go inside the fuselage. Be sure that your CG is within the CG range for proper flight performance.
