Meet the U-Glider - A great fun flyer with outstanding flying characteristics that will bring a smile to the face of even the most discerning glider guider!
At 1500mm wingspan, the U-Glider is big enough to give a great gliding performance while still being small enough to transport easily even without removing the 2 plug-in wing panels. The installed power system allows the option of a fast climb to altitude to search for thermals or simply grooving around and enjoying the superbly harmonized controls that the U-Glider offers.
Being supplied with a powerful 2208 2200kv outrunner motor, a 15A ESC and 3 x 6g servos already installed means that all that you'll need to add to have this fabulous glider airborne is a 4 channel R/C system and a 3 cell 800mAh LiPo battery.
Outstanding performance at a price that won't break the bank! It's what the U-Glider is all about.

I have to add that I have put a 40cm long adhesive white tape (50mm wide) on the fuselage underbody and a small one under the tail . This help keeping the foam undamaged when landing ! Lot of mods andt the result is improving the model.
The inside is full like an egg, because including also telemetry sensors... but this motoglider flies perfectly.Very happy with this light glider (looks like a DLG...).
Maiden flight this morning on a soccer field, no wind and French Riviera sunny weather conditions. Due to very good results, I have made 4 flights... and could do more: this was a pleasure, no need to mod trims!
I had read some reviews before buying and I had decided to modify some points at building time (some were well explained in videos):
- make wings apart for transport ease and no damage in car, so added a 4mm dia hollow carbon spar (2x12cms) with piano wire (2mm dia, 24cm long ) and fold it at middle to obtain the right dihedral. This also provides stronger wings and less fragility.
- replaced the wing screws by 3mm dia (30mm and 22mm) threaded ones.
- modify magnet system with specific steel wire latch to avoid canopy leaves the flight...
- made a clean installation of 2 digital thin servos in wings (MX95E, 4.3g): that gives better action on aileron and allows air brakes at landing.
- reduce the moving friction of all control surfaces (rudder, elevator, ailerons) by piercing half the length of the moving surfaces (dashed line effect) and added a cable guide in the middle of tail body (to avoid bending of the rudder cable and improves the precision).
- installed a 6 channel receiver (removed the box...) below wing. Choose TGY-iA6B with telemetry of plane battery voltage, RSSI and altitude.
With a 900mah-49g battery, CoG is correct: no need to add lead at tail or other. Decals equipped, flying weight is 285g and the stock motor-prop works like a charm...
Recommend...RCGroups has a thread dedicated to this U-Glider, and how to enhance it's performance and build. It is a really great glider, and is extremely stable in flight. I purchased two of these at the same time. The first I built to include a separate servo in each wing to give more versatility in my radio setup.
It does tend to be nose heavy, until you experiment with component layout. The canopy/lipo area is quite a bit forward of the wing and so finding any CoG adjustment is difficult to begin with. I ended up fitting the new FrSky G-RX8 receiver under the wing, and the esc in the fuse cavity, between the canopy and the wing. With a slight trim to each side of the fuse a Zippy compact 850 2S fits in perfectly with room to slide for optimum CoG.
With my second U-glider I followed a similar route, but fitted the rudder servo straight into the tail fin. this releases even more space in the canopy area which normally houses both the rudder and elevator servos.
This a great glider in the lighter winds when not much else flies, but will put up with strong breezes also. It's great on the slopes and really sniffs out the thermals as well. With a 350 2S the glider is as light as a feather for those thermally days. BUY TWO you won't be disappointed. Oh, and do read that RCGroups U-Glider thread.For $70 you cant go wrong! The glider is excellent. The stock electronics are fair and most of it is usable. After setting up and flying the U Glider per the instructions I've come to certain conclusions and made a few minor modifications that now make the U Glider an outstanding performer.(several others have noted these as well).
1. Immediately discard the single aileron servo setup for a dual setup as it allows camber and flaps or spoilers with an appropriate radio. The stock setup binds very badly and the supplied servo doesn't have the power.
2. Keep the elevator and rudder linkages smooth and the stock servos work fine.
3. A 2S 500Mah gives several powerful climbs and allows the use of the stock ESC.
4. I left my wing 2 piece and made my tail group removable with a single mounting screw from the bottom. Makes this a great compact travelling glider!
5. With the motor on a switch the throttle stick is free to work camber, flaps or spoilers. I mixed a bit of down elevator in with power.
6. The brake must be turned on. For those familiar with ESC programming, wait for the second set of tones and go to low throttle to turn the brake on. If not familiar, YouTube a video. Just can't have that prop free wheeling! %^)

Hope this helps.
MikeI use a 500 3s, upgraded turnigy esc, this bird makes my other gliders look like they're in a hurry to come down! ;]Maidened her today. Did the servos in the wing thing, & am flying her on a little NANO-TECH 460 3S, which lasts for ages. What a brilliant thing. It does tend to sky under higher power & porpoise a bit, but will climb happily on very little. I do have a little reflex on the ailerons, which may have caused this, will remove for next flight.
Gliding she is brilliant, wants to float for ever, & flies just so sweetly. Very slow, so not for the adrenalin junkies, but I love it.Hobby King & Australia Post excelled themselves delivering this one. Ordered Friday evening, delivered Wednesday AM.
Strong box, with clever but minimal packing meant it arrived in perfect condition.
I'm a little concerned with the light servos, but love the square carbon fiber reinforcing tubes. The build is going nicely, & it is an easy build. Although I would have preferred the instruction in the box, rather than glued on the outside, they are easy to follow.
So far very pleased with my purchase.Bit of a pain to build, limited instructions. Rudder and elevator servos seem weak but work alright. Also put servos in the wings, easy to do. Flies fantastic in calm conditions, launches easy and floats forever. Running both 2s 950mah & 3s 800mah with 12amp plush esc.Go for the two servos in the wings option for ailerons.Its much better.Spent some time trying to set up the centre mounted ailerons servo.First problem was the glue I used( superglue) made the aileron control tubes go very brittle and there was loads of 'slop' in the ailerons(lots of free movement)
Gave up in the end and fitted TWO aileron servos(like' Kevin' advised)
Seems to work well and perhaps Hobby King might do this from the start?.
