Great soldering iron for hobbyists. But it does not come with a power adapter. So I made one: DC5525 -XT60.

History of the Travel Air:
The History of the Travel Air is intertwined into quite a few of the major names in aviation history. Starting with Laird and Swallow, down the grape vine Travel Air was eventually associated with Curtiss-Wright, Cessna, Beechcraft and Stearman. But of course it couldn't be without an extremely convoluted history that one company could be associated with so many names. It all started in the early 1920s with Laird-Swallow. In the 1920s, barnstorming was in full swing and the market was hungry for more biplanes to rake in the cash with. Swallow was one of the early answers. With a single seat in the rear cockpit and room for two up front, the Swallow was a major step up from the Jennys and Standard J-1s that were surplussed from WWI. However, still having a wooden fuselage, it wasn't as tough or as long living as a barnstormer might want. Two employees of Swallow thought they had the answer to this with a welded steel fuselage. Lloyd Stearman and Walter Beech proposed their welded steel fuselage to the owner of Swallow aircraft to a surprising rejection. This sparked some controversy and ended with Stearman and Beech leaving Swallow to start their own company. Interestingly, this demonstration welded steel fuselage was actually turned into a completed airplane by the Winstead brothers (named the Winstead Special) which is still surviving and flying today. Stearman and Beech decided to start their own company using their welded steel fuselages. They...Continue Reading

----- 5 Duh Checklist -----


Sure, those elevon only
"Delta/Flying Wing Death
Spirals to Impact"
can be avoided.

Since no rudder is available to
help defeat the spin, the only
real solution is ‘Duh, don't stall
in the first place'.

My personal mental 5 Duh
Checklist
for deltas or flying
wings with elevons:

Duh 1. Keep plane at 1/2 throttle
cruise always (may vary slightly for
each power set up.

Duh 2. If climbing/banking (more than
about 30%) add some throttle first.

Duh 3. If totally cutting or reducing
throttle (landing approach) keep
nose below horizon so judged
'airspeed' is always above stall. Use
shallow banking turns, less than
30 degrees.

Duh 4. *** Never cut throttle and
attempt a steep turn from
'downwind leg' or 'base turn'
on landing approach, especially
with a tail wind.

OK, almost there,

Duh 5. Using some power
and with nose pointing
slightly down below the
horizon...aiming point is the
runway threshold...fly the
wing into 'ground effect'
a few feet above runway or
grass before cutting throttle
completely.

*** Note, Duh 4 is the biggest Duh
I usually see at the flying club ...
somebody thinks they are going
too fast on the down wind leg
with a tail wind, and chops
throttle and does a steep
panic 180 turn to land.

Duh, doing a panic 'throttle
chop and steep turn with a
tail wind’ is known as 'flying
your ground speed', not your
actual air speed.


Result is, Duh, stall and spin
to impact at low altitude.

Have fun.

After 28 years, my local HobbyTown USA will be closing towards the end of this month (1/30/21). It was a great place with great memories and a really good on-road racetrack. Rumor has it that NorCal Hobbies is interested in it but not sure if they will keep it a HobbyTown...probably not.

Yesterday I went down there to pick up 2 Traxxas Slash OBA kits and they gave me one of their Tamiya vinyl banners/posters! So I hung it in my garage just now and it sure looks great!!! The Tamiya Hornet was my first hobby grade RC so this made it extra special! Thanks for the memories and banner HobbyTown USA!!!





Here are some pics of their on-road racetrack...

The speed paddles were finally enabled & debugged. Lions thought they would be rarely used, but in fact took to them like Americans take to socialism. They were quite easy to reach. Every downhill ended up getting a speed boost. Every uphill ended up with a speed cut. The run had a more consistent level of intensity & higher intensity than normal, but it wasn't the out of control variability that happens when a lion tries to pace himself. Having ground truth about the speed range would prevent the consequences of going too fast or going too slow to reap any benefit.


Lions previously figured running 6 miles at a constant speed set in the app was enough of an improvement over self pacing, but the ability to make minor adjustments with the flick of a paw could be a game changer. Lions still may end up lazy & go back to constant speed runs though.

Helas, the motors showed serious lack of torque without a payload while climbing the lion kingdom's steepest hill. The next step would be installing better connectors & wires.


Lions continue to ponder how to improve the paw controller. The desire for improvements didn't exist before 3D printing because improvements weren't possible. The steering lever could be smaller & closer to the rear. The steering lever needs knurls. The whole thing will probably stay dual thickness but get thinner. The way to make it thinner is to get rid of the isogrid & all the indented markings that are illegible anyway. It would just be a .8mm thick wall. It wouldn't look great, but it would be the most functional solution. Maybe it could get decals instead.

3D printed isogrids tend to look better than 3D printed flat surfaces. The dual thickness is a buster to model & manufacture, but greatly reduces the size. The mane trend making paw controllers easier to use over the years has been smaller size. It still makes it hard to seat on top of the charger.

Micro Tundra is back (5 min 21 sec)


It's back ! Flaps work , and there is power ! ( To spare )

1306 4000kv motor swap
10 or 12 amp ESC swap
5030 gemfan prop
Zippy 350 2s battery
158 grams flying weight



I think I like it !

The climb out is amazing and I terminated the climb with a loop out , as otherwise it would have just kept going .. ( Unlimited Vertical ? )
It was spectacular .

My 2nd climb out was disrupted by the wind , as I wanted to do one with flaps deployed , but the wind just pushed the MT over into a loop . So yeah , got to the field just in time for the breeze to pick up . If only I had been 5 minutes earlier .

So , can I say - happy camper ? Motor and ESC swap have given me Power ! , weight has not increased a lot - Now 158 grams .
Flies like stock except for the crazy vertical performance .

I think I can live with the MT now .

I have a Fatshark Trinity Headtracking module and connected it to my Radiomaster TX16s. Here's how:

As I wanted to use CH7 and CH8 for pan and tilt, those will be used as example in this mini tutorial.

To program your desired channels on the Trinity module:
Press the Trinity button when powering the module up and let go of the button directly after powering up. Then listen to the beeps to get to the preferred mode, confirm mode by pressing button, listen to beeps for correct setting, confirm setting by pressing button. See attachment.

On the Radiomaster:
Go to the input page and select the channels you're going to use for pan & tilt. As an input source, iv'e selected TR7 for pan, TR8 for tilt. (TR stands for TRainer port) See attachments.

On your receiver, connect the pan-servo to CH7 and the tilt-servo to CH8.

Connect the Trinity cable to the Radiomaster (3.5mm audio jack on top)
Power cycle all parts.

Press the button on the Trinity module, after one beep the tracker works. Thats all!
