    Ease of


    It's funny how things in life work themselves out. Over this past summer I started to think about getting a multi-engine plane. I started looking at some of the multi-engine W.W.II bombers and fighters but wasn't sure what I wanted to start with. I also wasn't sure if I wanted to do glow or electric. Nothing really jumped out at me so I figured I'd take my time and do a little more research on it. So I pushed the idea to the back of my mind and figured I wouldn't do anything until next year.

    Well as things should go I get a call from Marc Vigod in September to see if I could help him out with a review that he needs to get finished. He had this Dual Ace that someone else had started to review but wouldn't be able to finish. After hearing that it was a twin engine and about 90% of the building was done I said sure I'd love to finish it for you.

    Since I got this plane with about 90% of it done I'm going to focus on the building issues that I was told about and the issues that I ran into while finishing the Dual Ace off.

    The Dual Ace comes packaged very well and includes some nice hardware to finish her off. The one problem with the included hardware was with one of the included clunks for the tanks. One happened to not have the center hole drilled out so it really was just a lead weight. But overall this wasn't a big problem to get corrected and I think this kit was just about the only one that I heard about to have this problem.

    The directions in the manual are very straight forward and easy to follow, so if you're familiar with assembling ARF's then the Dual Ace will be an easy build for you.

    The one area you need to watch out for is when you're assembling the nacelles. You really want to take your time here to make sure they line up right with each other and the engines. I had to realign the nacelles after I removed the top ones to check out the engines and tanks set up. They were all aligned up before I removed the top nacelles but when trying to reattach them they wouldn't line up properly again. So I had to make a couple of new screw holes to get them to line up again.

    The final issue I ran into while finishing the assembling of the Dual Ace was how tail heavy it was. I put the battery as far forward as I could and still needed a pound of lead to get her to balance correctly. I had gone and checked the forums on RCU to see if this might be a common issue with the Dual Ace which it seems to be.  One of the guys in the thread showed a tray that he had build and mounted to the nose wall under the cowling so he could get the battery and additional weight as far forward as possible. This really worked out nicely to help keep down the amount of weight needed to balance her.

    Once the Dual Ace was all balanced out I when and set up the control throws as they are specified in the manual.

    The one thing that I found to be a bit of a problem when connecting the wings on the Dual Ace was screwing in the two rear wing bolts. The heads on the bolts are made so you can hand tighten them. This works out fine for the bolts toward the front of the plane. There's enough open space to get you hand in. The open space for the ones in the rear is really tight. So either you need a small hand to tighten up the bolts or better yet is to switch out the supplied bolts with a pair of Hex head bolts. It's easier to use a socket wrench to tighten up the bolts.
    After getting the wings assembled on the Dual Ace and checking to make sure all the control surfaces are working correctly I put the canopy on and set her up on the ground to take some photos I realized how nice of a scale look this plane has right out of the box. I could easily see this plane sitting on the tarmac of one of our local airports.

    Having the plane all fueled and the engines tuned it was time for her first maiden flight. I gave the controls over to one of our more experienced pilots, Rich Blatt. He has a lot more experience flying multi-engine planes then I do and the wind was starting to pick up where I felt more comfortable with him flying and me filming.

    Rich lined her up into the wind and gave her full throttle and she climbed out every nicely. Once in the air she was a bit squirrelly and needed a bit of trimming to settle her down. Rich had her doing some really nice rolls and loops and she really looks nice in the air. Well my luck for the day didn't hold out to long since the winds really started to pick up so Rich brought her in. The Dual Ace comes in with a bit of speed and needs some time to bleed it off. I'd have to wait for another day to get in a second test with the Dual Ace since the winds wouldn't die back.

    The follow week I was able to get the Dual Ace back down to the field to have a second test flight with her. This time I had Chis Deblass being the test pilot while I was filming. The first test flight of the day turned out to be a short one. About 2 minutes into the flight one of the engines died. This is where I was glad Chris was flying the Dual Ace and not me. I probably would have done everything wrong in this situation but Chris brought her in with out any problems. If he didn't say that he had an engine out it would have be hard to tell otherwise. The Dual Ace continues to fly nicely during a single engine out flight.

    After giving the engine that quite a check and finding nothing wrong with it we refueled and Chris take the Dual Ace back up for a second test flight of the day. This time we had a full 8 minutes flight. Chris thoughts on the flight were that its takeoffs were fairly easy and straight once both engines came up to speed. He noticed that if one of the engines lagged behind it would pull to that engine a bit. The Dual Ace has enough power for a good climb out on takeoff. It needs a bit more elevator in the turns to help pull it around. During the single engine out he noticed that there was a bit of yaw toward the dead engine. He still had good control over the plane and turns away from the dead engine did result in some climbing of the nose but adding in rudder helped to straightened this out. As for the landings the Dual Ace would land nicely after bleeding off some of the speed and would settle in for a nice slow landing.

    Chris actually likes this plane so much that he wants first right of refusal if I want to sell it. I think that speaks for itself on the performance of this plane.

    The Dual Ace is a great looking twin engine model. It looks great on the ground and in the air and the sound of the twin engines is really nice. The twin Evolution .46NT engines give the Dual Ace some very nice power performance.

    The Dual Ace can be set up for some really nice scale flying but also has enough control surfaces and throws to do some nice aerobatic flying. Now you're not going to do any 3D flying with this plane but you can push the aerobatic envelope with it.

    It's also a great plane to choose for one's first multi-engine plane. It's slow flight and single engine flight tendencies are really good for the first time multi-engine pilot. If one of the engines should go out on you it will continue to fly without going into major crisis mode. You have the time to think about what you need to do to bring it down safely.This is not the case as I've seen in some of the RC crash videos where a multi-engine plane has one of its engines go out and before you know it, it's rolling over into the ground.

    The Dual Ace is a great plane for the price.
