Since the release of the first micro plane, the RC community just can't get enough of them! Initially they were twitchy, under-powered and didn't fly that great. But now with the help of AS3X, these tiny planes can fly just as well as planes four times its size! Take your pick of anything from the ultra-slow Vapor to the speedy F-16 or Habu ducted fan jet; there's a UMX out there to suit anyone. Horizon recently added to their UMX fleet with this classic Waco biplane; a replica of the YMF-5 produced by WACO Classic Aircraft out of Troy, OH in the 1980's. With its classic scalloped scheme, scale features and great power system, this should be another great micro to add to your collection. Let's open the box and take a closer look!
The great thing about the boxes these UMX micros come in, is that they also serve as perfect carrying cases. Two foam pieces lock the fuselage into the carrier and prevent it from shifting during transport.
Releasing the Waco from its foam cage reveals an extremely nice looking biplane with scale details all over. The scheme is bright and attractive, and it should show off really nicely on a sunny day.
Upon closer inspection, you notice carbon flying wires, webbed wing ribs, radial engine decal, wheel pants, landing gear fairings, a cockpit windscreen and even a pilot with a scarf to flap in the wind!
Underneath the wings, are the linear servos powering the ailerons. These ultra-lightweight worm-drive servos are a perfect fit for these UMX planes. The top half of the cowl is held on with 2 small magnets. Lifting that off reveals the motor and battery tray. The receiver and linear servos for the elevator and rudder are tucked back in the fuselage under the cockpit.
Just kidding! Charge the battery, bind it to your radio, go fly! :)

The big power to weight ratio of this micro makes taking off easy. You can choose to slowly advance throttle and use rudder to keep your alignment for a nice scale roll-out, or you can gun it and be in the air in about 2 feet! Hand-launching is also as easy as it comes, and gives you an option when a hard surface isn't available.
Landing the Waco is also pretty uneventful. It does loose airspeed pretty quickly though, so keep a click or two of power on until you're just off the runway. We were able to land it on our mowed field grass a few times without it tipping over, which impressed us.
We did end up needing a lot of down trim, so much so that we ran out of trim to give it. It was still easily flyable, it just wanted to climb with high throttle. We landed and pinched the half-loop on the control rod and reset the trim on the radio. I also noticed that the right elevator was slightly warped, which may have caused some of the trim offset. I plan to use some steam to get it back in line. I also shifted the battery as far forward against the motor as possible. I may end up adding a little more velcro on the tray, as the pre-installed strip didn't end far enough forward. This also means you could likely use a larger battery to add nose-weight and get longer flights! The 280mAh pack that Horizon sent me lasted about 3-4 minutes with a fair amount of throttle being used throughout the flight. Casual flying would likely see flight times in the 5+ minute range, depending on battery size. The motor surge/pulse that alerts you of a low battery is helpful, but not easily heard with other planes in the air...so it's always best to set a timer.
As you can hear in the video, the breeze did kick up a bit at times (around 5-8 mph), but the AS3X really helped smooth out the flight. We did get bumped around some, but really not bad at all considering the weight and wing area of this plane! I wouldn't recommend flying it in winds above 10 mph until you're very comfortable with how it flies, as those 2 large wings will catch a lot of air.
Flying the pattern nice and slow at half throttle was fun and very scale looking. Tracking was not an issue.
As said before, the UMX Waco is not lacking on power...so when you get bored of slow scale flying, punch up the throttle for unlimited climbs, fast passes and quick rolls, snaps and tumbles! This little thing can do a lot more than you think! My pilot put it through quite an array of maneuvers, and it did most all of them very well for a micro biplane with a lot of wing area. While Alex was doing rolling circles, hovers and other crazy stuff, the scale aerobatic loops, rolls and stall turns all looked and performed excellently. Inverted needed a fair amount of down held in, but handled just fine.
The UMX Waco is a terrific scale-replica biplane that will be at home in any park or flying field. The scale details show off great in the air, and the flight characteristics make it the perfect Sunday evening flyer. It has plenty of power to do endless verticals and aerobatics, and tons of wing area to help it slow down amazingly well. The AS3X helps smooth out rougher air and make it feel like a bigger plane.
The UMX Waco will certainly be in my back seat every time I go to the field for quite some time, or at least until Horizon releases another micro that we can't be without!
