Nature Inspired Precision UltraLight Radio Controlled RC glider

After a very successful launch of the original UltraLight FireFly, the much-awaited FireFly 2.0 is finally here. With some major airfoil adjustments, an aerodynamic inline fuselage that will guarantee a much smoother flight with incredible slow speeds and virtually zero stall characteristics, the perfect recipe for caching thermals with ease.The combination of the root chord and tip chord airfoil design and enhanced reflex, (auto stable airfoil) allows for a more hands off level flight without the need for heavy ridge lifts or any headwind for that matter.Total weight of the glider at 80 to 97 grams depending on the amount of glue used and the type of lamination film used for the wings. The wings can be left uncovered as well to save 10+- grams of weight. The FireFly 2.0 uses a single cell ( 1S 300mAh ) Lipo battery to power the receiver and two sub micro 5gram servos with adequate torque of at least 0.82kg.cm on a 4 volt battery. Click here to see servo options for the FireFly.The FireFly 2.0  is a 32″ inches wingspan DLG, HLG, bungee, slope soaring, thermal catching rc sailplane, designed for ultimate glide time due to its ultralight frame, improved wing area and low renolds number, taking note laminar flow occurs at low reynolds numbers. Gliding at low weight range means you have a better minimal sink, this simple concept has been lost in RC modeling due to heavy molded foams and composite material.

The FireFly 2.0 glider can be flown in 3 different variations.
1. Park DLG glider
2. Slope soaring glider
3. Bungee launch glider
FPV equipment can be added for first person soaring as well

FIrefly 2.0 for my son

My son who is 13 but not savvy with Gliders found your site and wanted the FIreFly DLG. I have a friend with a controller and he let me borrow it so I can see if my son can fly it before I spend money on a controller. First I tried to fly it with mixed results a couple nasty crashes but no damage to the Glider. I then let me son try it and he was actually better than me and he flew it at our local park and managed to give it hang time of 2 minutes until he lost control and it came down on the grass but its well made so nothing broke. Thank You Micro Birds now my son has a new hobby and can fly it pretty well after lots of practice. Im going to buy him a controller now. Once again thank you. I recommend this for adults and also teenage kids. This thing is a real gem. 🙂

Firefly 2 exceeded my expectations

i purchased my first FireFly 2 in hopes to glide and catch thermal lift right behind my home where a slight slope gravel leads to a wash, as the firefly is advertised to be one of the lightest rc gliders in the market, and sure enough she took air with ease, the lift was unbelievable form such a light weight glider mine was roughly 98grams with the battery
thank you for such a great glider kit

Thank you

having flown my alula glider for over 5 years i was looking for something half the wight and lee was kind enough to help me pick this wonderful glider it sure does catch thermals with no effort, i will need stronger servos for my next build
