Tower Hobbies Uproar V2 .46/EP ARF
An updated version of a sport favorite
An updated version of a sport favorite
Those of us who have been in this hobby for a while can certainly remember the original Uproar 40 kit. It was easy to build, and its all-around flight capabilities made it an instant favorite. It took a while, but version 2 is finally here. Gary Wright’s original design has been updated for even better performance, and timechallenged pilots will appreciate that it’s now an almost-ready-to-fly (ARF) model.
The model comes fully covered, and just like the original, it is built with an open balsa/light-ply structure. It’s designed for either a .46-size glow engine or equivalent electric power such as a RimFire .32, and it has hardware for both, including engine mounts and fuel tank. Speaking of hardware, the plane comes complete with everything you need besides radio gear and the powerplant. All items are neatly packaged in baggies and grouped together as needed for the assembly, which really helps keep bolts and screws from getting lost or mixed up. An excellent manual guides you through the assembly and offers a lot of construction tips and hints.
The Uproar V2 is an excellent choice for intermediate pilots or advanced beginners as well as expert pilots who want a go-to plane that can do everything their hearts’ desire.
THIS PLANE CAN COVER A WIDE GAMUT OF FLYING AND WILL BE THE ONE YOU GRAB WHEN YOU CAN TAKE ONLY ONE BIRD TO THE FIELD. JUST LIKE THE ORIGINAL, THE TOWER HOBBIES UPROAR V2 CAN BE BUILT AND FLOWN BY NEARLY ANYONE AND WILL CERTAINLY BECOME A CLASSIC IN ITS OWN RIGHT.
When I first picked up the box, I was wondering if Tower Hobbies accidentally sent me an empty carton. This thing is light! It’s basically a high-lift wing with a minimalistic fuselage and tail. I knew it was going to be a fun plane to fly.
Assembly is typical for a wooden ARF. There is just enough work to be done to make you feel like you’ve accomplished something. There is minimal prep of the covering material prior to the assembly, and a quick once-over with a covering iron or heat gun will ensure everything is taut. A few spots of the covering need to be removed, like servo openings and wing-joint areas, and it’s a good idea to save the removed covering pieces for spot repairs in the future. Hinges for all the control surfaces need to be glued in place, but they come preslotted. The tail feathers feature tongue-and-slot alignment, which makes it easy to ensure that the assembly is true. Don’t go crazy with the epoxy, as any extra unnecessary weight will need to be compensated for at the front end to achieve balance.
The two-piece wing (an update from the original one-piece wing) plugs onto a 3/4-inch aluminum tube and is held in place with a simple tab/bolt setup, making transport and storage a breeze (although with a 47-inch wingspan, the Uproar is easy to transport fully assembled). One of the differences from the original design is the removable side-force generators. Since the fuselage has a very low profile, the sideforce generators allow the Uproar V2 to easily perform knife-edge flight as well as provide additional directional stability.
IN THE AIR
With the recommended motor and battery, the Uproar V2 balanced just a tad tailheavy from the midpoint, which the manual recommended. The Uproar does have a wide center-of-gravity range, but I always like to test-fly at the suggested point. Despite adding just a bit of lead, the model came in right at the manufacturer’s recommended weight.
With all that wing and plenty of power, the model was airborne in just a few feet. Control throws on low rates were very relaxing, and once I got a feel of the handling, I switched to mid- and 3D modes. As you can imagine, with those large surfaces, the Uproar’s characteristics go from mild to wild.
Landings are a pleasure, and a bit of power allows a nice pitch-up attitude for a slow three-point touchdown. The long gear works great both on pavement and in less-thanfreshly-mowed grass.
GENERAL FLIGHT PERFORMANCE
Stability: At the recommended center of gravity and low throws, the Uproar V2 can be a docile plane. It isn’t quite a trainer, but it is very predictable.
Tracking: With its flat wing, the Uproar V2 is a point-and-go type of plane. The side-force generators do keep things pointed in the right direction, especially when the center of gravity is in the forward range.
Aerobatics: Move the center of gravity rearward and go to high-throw settings to unleash an aerobatic machine. Though not quite a full-blown 3D plane, it will do pretty much anything you can think of.
Glide and stall performance: This is a clean airframe, and it has a surprising amount of glide when kept flat. Point the nose up without power and the light airframe quickly runs out of momentum. When it does stall, it’s straightforward and quick.
This is a true all-in-one plane. Whether it’s slow flying around the pattern or performing physics-defying maneuvers, the Uproar V2 is eager and willing. The addition of side-force generators increases its knife-edge capabilities as well as its recovery from extreme unusual attitudes. The Uproar V2 is a confidenceinspiring plane that begs you to try out new maneuvers because it is so predictable in its recovery.
Above: With the underside hatch removed, you can see the simple radio installation as well as the ingenious wing retention system. The fiberglass washers ensure that the wings stay put without marring the alloy tangs. Below: The Uproar V2 flies just as well inverted as it does right side up. Despite being a simple livery, it was easy for me to differentiate between top and bottom.
