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 is around 80 to 100 grams depending on the types of servo used and material used to cover the wings.

The wings can be left uncovered as well to save 10+- grams of weight. The FireFly 2.0 is powered by a single cell ( 1S 300mAh ) Lipo battery to actuate the servos and receiver.

Two sub micro 5gram servos with adequate torque of at least 0.82kg.cm on a 4 volt battery is optimal. Click here to see a list of recommended servos.

The FireFly 2.0  is a 32″ inches wingspan DLG, HLG, bungee launch or hi start, slope soaring, thermal catching RC sailplane, designed for ultimate hang time due to its ultralight frame, improved wing area and low reynolds number, taking note laminar boundary at low reynolds numbers. Gliding at low weight range and greater wing area means you have better minimal sink rate, 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

Covering your FireFly 2.0 wings

Best covering film to use on your FireFly 2.0 wold be Solar Film. There is limited quantity of Solar Film Lamination in stock. Click here.
You may also use UltraCote, UltraCote park lite, MonoKote or TowerKote, monokote being the heaviest film and ultracoat being the lightest of this group.

To cover the wings of the FireFly 2.0, a heat iron can be used. Mini heat irons work best with variable heat adjustment. Few brand names to choose from that may be purchased from ebay or amazon are:
Clover Mini iron ii
Mini plancha para patch
Mini-Bügeleisen MB-3415
Ming Yang sealing tool

 

Required to complete:

LOVEIT

I could not be happier with this firefly glider
This is such a great flying glider and light weight, we enjoyed the build process and learned a thing or two about building techniques, for the price and quality, i am veryhappy.. It's very durable too. I'm flying on a 300mah 1s pack and get around one hour of flying time, the CG right on the money at 45mm from the start of the wing airfoil
Love it. so pleased! !!

FireFly 2.0

Nice little glider that is easy to build. I never worked on foam before. I usually build balsa planes and I was amazed how easy it was to shape. It flies well even though I was a little sloppy on the build. I plan on buying another now that I have a little more experience working with foam. I definitely have fun chucking it around.

Super fun!

I have flown RC aircraft for going on 50 years. I fly power planes and 1 to 3 meter electric powered gliders primarily. When I saw video of the FireFly 2.0 I was captivated by the simplicity of the plane and it's ability to float on the slightest breezes. My kit arrived quickly. Packaging was attractive as well as functional. All contents were in good shape and accounted for. Building was simple and straight forward. Carefully following video instructions will yield a great little airplane that is a highly capable flier. Apply glue sparingly and try to keep the plane under 100 grams for peak performance. I have built 3 FireFly's and all are a bit heavier than 100 grams, one is actually 119 grams, and they all fly really well. The heavier the plane the higher winds it can handle (generally speaking) so if it is gusty or stiff breezes I fly the heavier plane and for no wind or searching for thermals I fly the ligher planes. It took me some time to get used to the sensitivity of the little birds to control inputs and adjustments. I think because they are so this way it is important to choose good quality servos for this application. The speed and accuracy of servo will make a difference in the performance of the craft for sure/ I installed LemonRx DSM2 4channel receiver in two of the planes and OrangeRX R410X as I use Spektrum 6 channel programmable transmitter. I put TGY 0025 servos in the lightest plane and Diamond D47 in the heavier model.. Kit fits together really well and was a pleasure to build. MicroBirds has been an excellent vendor. I have had a response to every email I have sent and have received a great deal of valuable information and encouragement from them. One of the best aspects of this new RC adventure for me is that I am approaching areas that I have been to before with a new eye. I am more aware of the terrain and the environment. Wind, wind speed, wind direction, topography and various features that were overlooked before now are front and center as I explore new places to fly these little birds, The wind is now my friend and I have found if it comes from the North I can fly on a small nearby hill at a park. If wind is from the South I can fly at a nearby fish hatchery where a small ridge creates more than enough lift for great flying. When there is no wind I can step out in my back yard and fly around by repeatedly launching and returning the plane to catch or land nearby. I am now addicted to gliding! So much fun. So exciting when the planes catch lift and start flying around like a powered craft! The planes are durable and I have crashed and repaired my "trainer" many times with poly glue. Like any new skill it takes time, patience and practice to improve but the rewards are great and if you love to learn and love to fly there is a lot here for you! Great product that does what it is supposed to do. Available at a reasonable price and backed up by a quality individual with years of expertise that he appears to be willing to share. This has been one of the very best purchases in my R/C modelling career and I am happy to support an honest and reputable vendor. Thank you MicroBirds! Keep up the good work!

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

by Clark C. Harrison on FireFly 2.0 UltraLight DLG RC Glider
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
