Status: offline 		I work in one of the local hobby shops and we got 4 of them in yesterday. They look nice. I assembled one to look at. Found the magnets holding the canopy on had come out of the foam where they were glued, also they gave me 2 of the same sides of the stand and they won't fit together that way. So I'll have to order the other side of the stand but no big deal at least I can build it still. I checked the other 3 for these problems and all was good. I'll pick one up Monday. Hopefully someone will get a flight report up here soon. Later Jon

Status: offline 		Mine is sitting on the floor in front of me! The LHS did not have the recommended Futaba S3114 servos. Actually, he thought they may have been discontinued. When i find a servo that fits, I'll let you know.

The plane is very nice.

Status: offline 		The S3114 servo is a newer servo. It hasn't been discontinued. Greatplanes shows them in stock.
I just about have my L-39 done now. I picked it up today. I forgot to get 2, 6" extensions so that is all I need to finish it. I weighted it complete (less the 2 extensions), it is 16.8 oz, with a Thunderpower 1320mah 3 cell batt. Looks pretty nice. Hopefully I can fly it this weekend. Later Jon

Status: offline 		Got mine the other day. First impressions:
- packed very well
- light and well painted. (some irregularities in the paint job around the edges of the canopy)
- magnets used throughout jet are strong (canopy, rear hatch, missles and fuel tanks)
- high quality construction.

Questions:
-manual says to use foam safe ca, but the video on the tower site says that regular ca can be used on this new foam?

BTW, the blue canopy is growing on me. Looks nice.

Have you flown yours yet Jon Wise?

Status: online 		If it is anything like the synapse you must make sure canopy is secured. I lost mine in flight 2 x's on the synapse. Also the fan unit could use balancing. Mine vibrated so bad I thought it was going to come out. The paint chips and cracks off easily. If you tape anything down it will come off. The paint will stay on the tape. Foam safe CA is not good to use on the synapse...not sure how it works on this one. I used 30 minute epoxy with great results. The B-8 servo's that come in the rxr are junk IMO. The both stripped on first 3 flights. No crash! Just pulling straight up from level flight stripped them.

These are the things i observed from my synapse....not the L-39. I am assuming they are made from the same material.

Status: offline 		No, Haven't flown it yet. We just got 6" of snow yesterday. Was hopeing to fly some time in the next couple weeks.
I used 30 minute epoxy to assemble the plane. I also used the S3114 futaba servos on mine. Finished weight was 17.2 ozs. with TP 1320 mah 3 cell li-po. I have run the motor some and didn't notice any vibration to speak of. Mine seems fine. Later Jon

Status: offline 		I am interested in getting one of these jets. I have four left over servos from a venom air corps night ranger II (boy what a piece of junk) and I am wondering if they could be used for the L-39. Towers website states that it has 17 oz of torque with a weight of .3175oz.

Status: offline 		Flew mine this weekend...got three flights in yesterday with the wind gusting to 20mph. What a gas! First launch was hairy ...plane rolled 100 degrees to the right but I was able to get it level before impact and gently pulled up and into the pattern. I strongly suggest high rates on launch...The plane penetrated the wind well and the downwind pass was...zippy! The ground surrounding our asphalt runways is rough so I wanted to land on the runways. I reinforced the servo arm covers with glass on the inside and epoxied about 1/4" square aluminum skids on the those covers, under the nose and under the tail. It lands great but the tip tanks can pop off unless it is greased in. I got probably 10 minutes on TP 1320 3 cell lipos but I did spend some of that time "hovering" in the wind. It loops from level flight but looses speed at the top so a slight dive will make them more symmetrical. Even stock-out-of-the-box, for a hundred bucks you're going to like this plane!
