The L-39 Albatros was developed in the Czech Republic as a light attack and trainer aircraft. It is believed that approximately 2800 of the L-39 Albatros air craft are still in service today.
Featuring a large 90mm EDF unit and powerful 3660-1600kv Brushless inrunner with cooling vents this large scale EPO jet will sound as good as it looks. The 6 blade EDF unit comes with the motor pre-installed for easy setup. 5 x 9g 1.8kg torque servos will be required to handled the control surfaces and steerable nose wheel. The fixed landing gears also include working suspension and adds to the scale look and feel of the L-39. A 22.2v 4400mah 6s Lipo and your own transmitter and receiver (Tx/Rx) will be required to complete the model. Finished in an authentic Czech Republic Air Force color scheme the L-39 Albatros will make an impressive addition to your fighter squadren.

My order called for EPO foam. However what I received was not in my opinion EPO as the paint came off with every scrape and ding. I added servos for the flaps and routing them out sure did not feel like working with EPO foam. They should include some touch up paint to take care of the paint removal which will definitely occur when assembling the modelThis is my first 90mm jet and it's very nice! I posted a vid in the vid section for the chinese warehouse version that's plug and play. I'm the one w/the sunglasses setting it up in the beginning ;)
The wing spare is a nice feature as well as the EPO. Flight characteristics are pretty good too, even though it doesn't have a rudder or flaps. I got the Hobby top gun/Flyfly retracts here at HK too (EXCELLENT PRICE!!!!) and they work surprisingly well for 45 bucks1!!!!
The stock motor combo works well, just make sure it's fairly balanced. I simply used hot glue and duct tape on the rotor to get the main resonance out. And DO NOT use high timing on the motor. I did that in the vid and the reason why i couldn't taxi back was because the motor burned out and melted the shroud. Like almost all inrunner EDF setups, it's safer to use low timing w/the exception of those built for higher timing like RClander stuff.
There are some things to be aware of in terms of the landing gear, which was the worst part of the plane. The strut posts that came were pretty good but kept bending, especially the nose one because it wasn't case hardend. So I drilled the holes in the retracts and landing gear a little bigger and just used some fat case harded bolts from a hardware store and they work way better.
Doesn't like to handle slow speeds as well, especially when there's wind that's not a headwind,EDF plane. . EDF 5s. Thrust 1.5 . 4 .Awesome right out of the box, pulled 58 amps on a turnigy 6s 2.65 batt and flew great. Switch over to a ARC 36/75/1 and wemo minifan pro 90mm. WOW disappears straight up in a matter of seconds :)This is my first EDF plane, so I didn't know what to expect. Very pleasantly surprised, the flight characteristics are very good, plane handles like a dream. The stock motor on 6S is ok, but a little more power would be nice.
I run it on a Turnigy 5000Ma 6S 20C pack, after a 3 min flight it uses 3/4 of the pack, at the high altitude i'm at I need to fly it mostly at full throttle. The motor tested just over 900 Watts static, more like 1400-1500 would be desireable.
I recommend it, but you should have a good bit of building experience before trying to tackle this one.
