Tim, I hope you enjoy your new little beastie

I still love my UMX Mosquito and UMX T-28.

Maiden report:

I took the Beastie out to the field and gave it a try. In the wind, I love me some wind. I have since put a total of 4 packs through it. The little guy performed quite well. It has a ton of straight line speed and had seemingly unlimited vertical. The plane responds quickly to controls, although I would not recommend anymore than 10% expo in the rudder. The roll rate is amazing. It left the ground in about 5'. Overall, a really impressive bird.

That said it is not quite a 3D machine. I will check my factory CG, but the plane was quite nose heavy, especially for a plane marketed to intermediate pilots and 3D pilots. In the video you can hear me dialing in up elevator. In the third and fourth packs I was in a limited wind situation. I am now more convinced that the CG is set for non-3D. It has all of the power to do 3D, but lacks the deflection, with this CG.

Another potential issue is the AS3X receiver. I hung the plane in a angle turn, and released my ailerons, with the assumption that the plane would hold angle. That is the usual situation. Instead, the gyros pulled the thing to wings level.. That would have been awesome 3 years ago, now that I can fly a little and know what a plane should, and should not, do, that auto correction is problematic at first. I will see how that factors into future for me. I do think that the AS3X technology will sell a ton of kits and parts to folks that learn to fly with it.

I will try to make this a 3D bird, but I have my doubts. Here's the maiden video,

The guys in the AS3X Sbach forum also say to use very little expo but I set mine to the typical 60-70% on high rates. That's how it is set up in my video. No problems. Too windy to fly this weekend, even for AS3X.

Nice Tim, Love that tricky move at 2:15 there were several others, but that one was note worthy for me

OK, this is why you do not trim out, to fit your preconceived notions, a new plane.

I now have 10 packs through the plane. I have ditched the low rates, everything is 100%, I have reduced the expo to 10% and am probably going to go linear on the rudder. I also ditched the up trim in the elevator. And finally, I made a physical adjustment to the rudder. Now the plane is nearly what I wanted it to be.

Looking good, and love how the little AS3X looks - might have to get some 3-axis gyros in some of my smaller planes when I get the time.

Heres the progress on my nearly completed version of a Fritske / Rockwell 'La Stick'... excuse the poor quality photo.



I scaled the original, intended for a Cox .020, up by 30% with more or less no other additions other than zero dihedral, a Cox .049 and more channels for control (elevator/aileron/rudder). She has a 1oz Sullivan tank, 300mAh 2s lipo pack with 5v regulator and 3 servos. I'll also be putting gear on her when I'm done as shes a little bit large for belly landing IMO.

Cheers - boingk

What a day! I was at the field at 7:45 and had it all to myself for the first couple of hours. It was very foggy when I arrived but it didn't take long to lift and become one of the most perfect flying days we've had all year. Calm, sunny and warm in the middle of November. Many, many flights. Got home around 4:00. Need a nap.
