There is a micro servo mounted centrally in the wing same set up as with mechanical retracts and a sequencer to time and slow the servo,

Maidened this morning. I should not have due to the growing crosswind. I noticed yesterday the front wheel kept lifting when I would do a fast taxi down the runway, causing me to loose steering. I realized this morning it was due to the ultra tall nose gear so I kept the elevator down and since it gave the nose some traction I took off, another mistake.
CrashlandL39 (2 min 0 sec)


She flew plenty fast and aside for the elevator control being too strong she handled well.
Upon landing the wind had me spooked and that added to the stress of a possible low battery; it did not end well. Looking at the video perhaps I should not have aborted the first attempt to land. I finally came in way too hot.
I am planning to design some break away nose gear as opposed to the stock design. Next time I will use some patience and wait for a dead calm day; good advice to anyone here who figures he can take a chance on a maiden.

Fixed the nose gear support. Not as hard as I thought. Just bought some thin plywood from the hobby store and went to work. Now the height of the nose gear is perfect and I'm ready to fly again, weather permitting.

Ahhh.. Thats not to bad urrl. Just a crappy landing. We all do it from time to time. The plane is still in one piece.

Hint: Do not use flaps in a cross wind landing (or at least I dont and it works for me)

Urrl,

Good to hear it was an easy fix. Thanks for showing the settings you used. I mounted a little 5V fan on the ESC to cool it.

some guided selection

Dear all, I have been suggested by a good friend to step towards the habu 32.
It is a great suggestion, but I am always keen on attempting my own way through the hobby king supplies, even if it seems like a mania at times...
Could you please tell me what you think about picking between the habu 32, the l-59 and also the bae hawk? I find them similar, am I completely blind and missing evident, fundamental differences?
Thanks a lot!

I've had bad luck with the BAe Hawk. It's IMO easier to tip stall on take off than the L-59. Someone else may be able to tell you about the Habu32. I would guess if it's a foamy it would be easier to fly. I don't think it is especially fast in stock form from what I've seen. The L-59 is a great flyer but you can easily overdo the approach speed in a landing.
Here's a few clips of my BAe Hawk

The Habu32 is a great composite sport jet. Mine has been my weekly flyer since they came out. I use the Habu to warm up before flying my larger EDF's and turbine jet. She flies fine stock but mine performs really well on the 6s Mega motor in the stock fan. I probably have 500+ flights on her by now and she is as good as new. You're gonna drop nearly $1000 to put a new one in the air but you won't be disappointed.

Nice Hawk Urrl, however I noticed that you did not fit any wing fences as per the real machine, these are mandatory to stop tip stalling...

Here is my recent elevator servo horn adjustment for this morning's flight.

Three consecutive flights this morning, all with nice landings. This video is a combo of all three...
My Hobbyking L-39 2nd Flight (2 min 23 sec)


I have both a low speed and high speed pass in the video.
It's fast enough for me even though I have an 8S balanced fan waiting on the shelf I don't think I will be upgrading any time soon.
Really happy with this jet now that I bring it in more slowly for a landing.

Urrl,

Nice flights, I noticed you chose not to use flaps for landing. Any reason? Agreed your field is awesome. Where is it,how long and wide?
