Description

We are very pleased to have the amazing Sugar Glider F5K. The Sugar Glider is an easy to build ultralight electric glider that thermals with ease, making it an excellent beginner's model. The brainchild of Sangyun Lee, who has been promoting it on Instagram so effectively that it has built a worldwide following. Taking off where the Elf Pro El stopped, the Sugar Glider is a great small thermal soarer, but is also a fun model to sport fly on a calm day.

The model is easily built from laser cut balsa with a carbon tailboom and wing spars. The complete kit includes an excellent manual.

A powertrain with a specially designed folding spinner and prop assembly and motor is available and highly recommended. The Sugar Glider is availalbe in both V tail and X tail versions. The V tail is more popular.

Please look at this great Sugar Glider Construction YouTube Playlist and here for build info. Unless the bundle is selected at checkout the RC, motor and prop are not included. We recommended Oralight and Feather Cover covering film for this model.

Bye bye regulations!

Unfortunately all UAVs here over 100g have to be registered and the code transmitted from the UAV in flight. I was looking for some time for a powered kit to challenge these rules and the Sugar Glider turned out to be the perfect candidate. At 100g the slow speed performance is really fun and forgiving while the airfoil still has plenty of headroom for speed and penetration.
The total structure came in about 25g lighter (60g) which meant a smaller motor (1104) and battery (2S 250) could be used.
It`s not going vertical but good enough for 5 - 7 decent climbs plus a safety margin.

I enjoyed building this model. Easy to follow video. However, I ran exterior servo rods and fiberglassed the fuselage. I ended up with adding a little tail weight but it's a solid controllable model. I did have to work out a warp in the wing due to improper covering. But it's a blast to fly and looks nice.

Most fun I’ve had with a small glider!

It seems to do everything well and turned out great. The kit is very nicely made but slightly more difficult to assemble than expected. The servo mount shown in the videos isn’t included in the kit so you have to fabricate your own, but this is easily accomplished using some of the spare stock. Make sure to use a lightweight covering to prevent over shrinking the wing since the trailing edge side can be fragile. The BMS-101DMG servos fit perfect barely clearing the bottom of the wing. Anything wider will require some additional planning. I wish it came with a full-size plan but that would probably just increase the price.

AUW came in at 123g. Instead of the recommended equipment, I used some leftover components in the build and was very happy with how it all works together. Here is my setup:
Motor EMAX 1106-KV4500 with Graupner CAM 4.7×2.3 prop & VM 25mm Spinner for 11xx Motors
Rcvr Lemon DSMX Diversity LM0034Z
ESC MX-12A
Servo 2 x Blue Bird BMS-101DMG
Batt 2S 350 HV (GNB3502S70AHV)
