The Twist series of sport planes has been an Iconic staple of the Horizon Hobby Radio Control Catalog for many years. The original 40-sized Twist was such a success that they increased the size and produced the Twist 60. This larger model sold so well that they produced an even larger Twist 150. I have had the very good fortune to have owned and flown all three sizes. Every one of them was an exceptional flyer, extremely maneuverable, and just plain fun to fly. As much as I enjoyed all of my Twists, I always wanted a smaller electric-powered version for those spur-of-the-moment flying opportunities when the sun was just right and the wind calmed down. I even started scratch building a smaller Twist a couple of times, but finally gave up in frustration due to my lousy scratch building abilities. I resigned myself to the reality that I would have to be satisfied with flying the larger Twists at our club field.
You can imagine my surprise and delight when I saw the new E-flite Twist 480 3D ARF in the 2012 Horizon Catalog! It was exactly the size I had imagined and it was an ARF! This new 35 inch wingspan Twist would be the perfect size to tuck inside most any vehicle and it looked ready for some serious lunchtime hucking or after work relaxation.

OK. I've waited as long as I possibly could, I have to open the box and get started building this beauty.

28-Page Assembly Manual |
Photo-illustrated building instructions |
The 28-page Assembly Manual includes numerous pictures and helpful building tips. Seasoned ARF builders should have no problems with this plane. Carefully inspect all the various parts and tighten the UltraCote covering on the wings and fuselage as needed before construction begins. The stated 1 to 3 hour assembly time listed in the manual may be a little optimistic though. I'd recommend you take your time and enjoy the build process.
Wing assembly is the first step listed in the manual so that's where I started my build project. Servo installation was required before aileron hinging could proceed. The recommended E-flite DS-76 servos were a perfect fit in the wing servo cut outs. I noted that the servos had to be installed with the output shafts facing the trailing edge of the wing and the servo leads had to be routed through the oval shaped holes behind the wing tube.

The CA hinge slots were precut in the ailerons and in the wing trailing edge stock, but needed a 1/16" wicking hole drilled in the center of each hinge location. I found it easier to dry fit the hinges and align the ailerons before drilling the wicking holes. By pre-fitting each hinge, I was able to mark the exact center of each hinge location so that when I drilled the wicking hole, it would be in the center of each hinge location.
The landing gear assembly was next. It took a couple of tries, but I finally got the nuts tight without binding the wheels. I later discovered that maybe I should have CA'ed the rubber tire treads to the wheel hubs at this point in the build. During flight testing, a slightly sideways landing caused the rubber to slip off the wheel hub and bind up the wheel assembly. On the next landing, the tread came off entirely and slipped up the landing gear leg. Just a couple of drops of CA fixed the problem, and the treads have stayed firmly attached to the wheels ever since.

Partial tread separation - BRAKES! |
Luckily this stayed on the gear and out of the grass. |
The fuselage assembly began with the installation of the motor. For the Power 480 motor, the "diagonal" mounting holes were used. I soon discovered that connecting the motor/ESC leads was going to be a challenge. The leads needed to be plugged together below an inaccessible floor plate area of the fuselage. I was able to route the leads below the plate and up through a side hole to make the plug connection, and then stuff the connected leads back through the hole into the area below the plate. I found that I could use a 2.5 mm hex wrench to hold and help route the female connectors below the plate.

Once the wing halves were slipped into place, the fuselage was ready for tail feather installation.

The horizontal and vertical stabilizers slipped into place and lined up exactly with the wing and fuselage. A touch of CA and the tail was done. I then added the optional pilot figure under the canopy and I'm glad I did. He added a lot to the looks of the plane.
Once again the recommended E-flite DS-76 servos fit the fuselage servo cut outs perfectly. The Spektrum AR6115 receiver was installed per the manual, but the left aileron servo lead would not quite reach the Aux1 receiver port. I installed a short servo extension to make the connection. I guess a Y-harness servo extension would also solve the problem, but I wanted to try spoileron and flaperon mixes at some point, so I needed the servos on separate channels. I normally install short servo extensions for both aileron leads on most of my models to make wing removal easier but the Twist 480 is small enough that I didn't plan on removing the wings anytime soon.

The completed Twist weighed 1 pound 13 ounces RTF. At 29 ounces, the wing loading was only 10.34 oz/sq. ft. and the wing cubed loading was a light 6.2. With these numbers, the Twist looked like it was going to be a real floater. With the E-flite battery pushed all the way forward against the firewall, the model balanced exactly at the recommended point, 3-1/2" back from the leading edge of the wing.
The manual lists the recommended control throws for low rates (sport flying) and for high rates (3D flying). I set the control throws per the manual including the exponential settings. I found the 25% expo to be just right on low rates, but I needed to increase the high rate expo to 40% to tame down the movements around neutral.
The Twist 480 3D is touted as an ideal aerobatic trainer and an introductory 3D model. I think E-flite was being very modest with these claims. I think the Twist 480 is a great sport plane with excellent aerobatic characteristics and a wonderful introductory 3D plane.
However, I was not impressed with the way the Twist flew with the recommended 12x6E prop. It didn't fly bad, the big prop just seemed to really load the motor/battery and it seemed to need a lot of throttle stick to hover. I switched to an 11x5.5E prop and the Twist really came to life! The smaller diameter prop had fewer torque issues and the reduced pitch resulted in more stable hovers at lower throttle settings. The motor and battery were barely warm after a full, hard flight. I checked the power input with the 11x5.5E prop and measured 25 amps and 279 Watts for a power loading of 155 Watts/lb.
Even though the Twist is a conventional gear plane, it is very mild mannered on takeoffs. The rudder and tail wheel were very effective and gave excellent directional control on the ground and in the air. Takeoffs were smooth and straight with just a touch of right rudder to keep things lined up with the runway. When I eased the throttle up from idle, the Twist would takeoff in about 30 feet. Full-power takeoffs occurred before the throttle could ever reach wide open, and the liftoff occurred in inches rather than feet.

The Twist 480 is a joy to land. It is so steady and stable, it gives you the confidence to try different styles of landings. That big thick wing lets you slow the Twist down to a slow crawl for landings without ever a hint of falling out of the sky. I could keep a little power on and land on the mains and keep the tail up for the whole length of the runway. Three-point landings were routine with great elevator feel all the way to touchdown. I had great fun landing nose high and letting the tail wheel touch the runway before the mains.

The Twist 480 is a great aerobatic airplane. It performed all the routine aerobatic maneuvers with ease. However, I found that I needed to reduce the low rates slightly to get really smooth, precision aerobatics. With normal low rates, the Twist 480 flew just like a full-size sport plane. This little Twist can loop and roll with the best of them!
Since I have only recently started to fly 3D, I think I am among the target pilot audience for the Twist 480. The plane flew so easily and solid that it wasn't very long before I took it up high and started trying some of the 3D moves I had seen the big boys throw down. The Twist was so forgiving, that when I would get mixed up or disoriented, it would just keep on flying and give me the time I needed to get out of trouble.
For 3D flying, I found it helpful to shift the CG back 1/4" behind the recommended 3-1/2" location to 3-3/4" from the wing leading edge. This more rearward CG allowed the Twist to hang in a hover better and helped with snap and spin maneuvers. Upright and inverted flat spins were now routine and the Twist 480 would stop rotating as soon as the sticks were released. High alpha flight was easy with the thick wing, but I'm still working on my Harriers to balance the throttle and elevator.
Not really. The Twist's oversized control surfaces and flat wing platform are not suitable for a true beginner. However, with reduced surface throws, the Twist would be an excellent aerobatic trainer. For most intermediate pilots, the Twist 480 would make an excellent 3D trainer.

The Twist 480 is a worthy addition to the Twist legacy. The compact 480 version retains all the wonderful sport flying characteristic of the original Twist series with the added bonus of 3D capability. The perfect mix of light weight, a thick airfoil, and plenty of power makes this new Twist 480 3D a Winner!
Reduce the low rates to 70% of the posted values and you will have a smooth flying aerobatic pattern plane. With the recommended low rates, you will have one of the best sport flying planes available today. On high rates, hang on to your hat because the Twist will exceed your expectations (and maybe your abilities) in a heartbeat. Better plan on a little extra altitude before you switch on the high rates for the first time.
I'm predicting that I will be joined by a lot more Twistaholics before this summer is over. Enjoy your new Twist 480 3D, but fly responsibly.

Awww jeez. I gotta get another on and do it right. The first one was slapped together with a park 450, 4 parkzone DSV130's (which I had to cut the slot bigger to fit. I didn't have mounting screws so I glued them in!
during the first few flights I noticed the servo not centering right. I would stay slightly up after using up elevator, nd the opposite after using down. It was qite unpleasant and the plane was flying me instead of the other was around. Eventually that cruddy servo went bad and locked up, and the plane died. Ill have to get another one and use the Dx6I I'm getting with it.

Sorry to hear about the lost bird RCA. I think you deserve another one, very soon!
CSpaced, Thanks for the kudos, you ought to try one out ASAP. pathfinder, the 480 is perfect. 160+ watt/lb is very impressive. ![]() McD |

A good 3D pilot told me mine has too much right thrust built into the firewall. I've reduced it by 2 washers and it tracks better. Anybody else have a similar experience? I also gotta change my elevator servo. I get pitch trim changes thru out the flight. And I found landing it tail heavy to be an adventure

Did the expert fly it first, or just think that it had too much offset? Interesting observation though, I don't think that's a problem with mine, but I will pay more attention next time out. I have had no problems with landings, and am still playing with battery placement for cg preference. I'm not a 3d type flyer though, so different setups for sure.

Yes he was flying it at the time. I have a lower powered 450 E Flight motor in it. Part of my landing adventures are the cheapie elevator servo not centering I think. I do like the plane and now have about 20 flights on it and I'm well on my way to full blown Twistiest. I haven't seen the Twist 150 thAT THING MUST BE HUGE
