Just wanted to share this fun Traxx I've been toying with! We had that huge snowstorm in the northeast and I couldn't help myself! Traxxas shipped it same day which was amazing, had it in a few days!

Stock gear was good except the stock servo, lasted 3 times. Threw a cheap amazon servo and it's much better. I always like upgrading to brushless as I like the quality if those motors! This hobbywing with 550 3300 kv was perfect for the crawler, it doesn't hit too high of rpm's for the tracks. The Bluetooth feature seemed really cool, and I do like how you can adjust those features. It's mostly useful for adjustments as I am not standing near this crawler like one normally would.

at first I had a cheap camera / vtx that went right into the rx. But it fell off the top of the Truck and the tracks ripped the cord!

Grabbed the Runcam 2, and a 600 mw vtx to link up so I could get solid range around the yard. Even have a little porch with windows on all sides I can sit in and drive from with my Fatsharks.

It's a really fun truck to run in fpv, now I just need another 2 foot dump of snow and I'd be styling.

Anyway here are some photos, need to get a youtube going so I can upload videos

Testing new prototype of UV-C disinfection robot. The robot is equipped with fpv camera and remote control.
A separate switches on the RC are used to turn on and off UV top and bottom rays. The prototype is currently being tested and improved.

XK A160 with slightly more forward CG (7 min 19 sec)

Battery sits deeper into the nose now + no slop .
Hunts less .
Rolls much nicer ! I mean it rolls like a Jam Roll !

New problem

Moving the CG ever so slightly forward ! Now I dont have enough elevator to hold the stall .
My A160 when it stalls - It just drops it's nose . Before the CG shift , the elevator could just - and I mean just - hold the nose up !
Now it cant . My control rod is flexing quite a bit _ Full Up ! So those foam hinges are limiting elevator movement .

Something else to fix .

I got out today for almost 2 hours of non stop flying with my 48"Knife Edge and 48" Dan Wing 2 .
The temperature was 25 degrees and sunshine with a wind of 13 to 20 mph , I admit I was a little slow getting out the door but once again after I had a plane in the air it made all the extra clothes and climb up the hill well worth it .

A extra bonus today - I was flying hot laps back and forth across and down the face of the hill when I got a flash of something above me , after easing off and getting a little distance from the ground I was able to look up and found a good size red Tail hawk hovering 30 feet above my head and his partner was flying low over the field in front ,I felt honored to share the air with such awesome creatures !
I guess they saw the activity and were hoping that some thing would flush out of the cover I was zooming around over , in any case whenever I see birds of prey I am blessed .
There is more good wind forecast later this week -

I wanted to be able to control the brightness of some LEDs from Ardupilot flight controller.
I wanted 0 to 100% pwm output from the FC pin to drive the gate of a FET, then you can control anything (LEDs/motors/solenoid/etc), but Ardupilot does not have that function.

Ardupilot has servo passthrough function, it passes a RC channel from the Rx through the FC to a output pin. This will require a brushed motor esc, most of them are larger than the size of the FC, and fitting them on a 5" quad is a bad choice. Then I found on AliExpress for $3 shipped, a servo motor esc (for continuous rotation servos).

I got one and have tested it on the bench, its got some issues that I was not expecting.
1. Most Tx/Rx will not output below 1000us and above 2000us, this means you will maximum get +/- 70% speed (see picture).
2. Lowest PWM output is 17.5%
3. Maximum 6V. Maybe possible to modify for my voltage by cutting the FET driver supply trace and feeding more voltage, but I have not found the datasheet to the FZMOS-5X (so-8 package).

Large zero thro dead band 1390 to 1591 (200us)
See the attached picture for the PWM info.

So with the limitations of 6v, 1A, 17% to 70% max output, it will work out of the bag and its low cost, tiny.

iFlight Crystal HD is the most beautiful, Lumenier AXII HD has better Stubby antennas and TrueRC X-AIR DJI is the best, but also the largest DJI FPV antenna.

If you want the best reception for long-range quads, you should get two of the X-Air antennas.
Unfortunately, the antennas are very large and not suitable for everyday use. If you want to carry the goggles in your backpack, You would always have to unscrew the antennas. But the reception is great with the two X-Air antennas. The Lumenier HD and iFlight Crystal HD, on the other hand, are super practical. These antennas always stay on the DJI goggles, are noticeably better than the original DJI antennas and the price for the antennas is not too high.

Well, POOP ! Both of them flew, and both of them died, both due to loss of orientation and lack of altitude....seems like I'm going backwards.......I got 2 successful flights out of each of them....the third one did me in......let them get too far away, and against an overcast sky, well, what could go wrong?? lol...saved all the electrics, so I'm just out some foam and some time.......I've got plenty of both

Straight up pilot error......both birds were rather quick and let's say "responsive" to control trying to fly an epileptic monkey on meth.......I just couldn't recover quick enough.

But to take some "positives" away from all of this....I learned a new covering technique, a new hollow body fuse cutting technique, and that a CG located at 25% of wing chord might be a little too far back for me to control on the first flights......ya'

I calibrate all the required things and done the integration according to ardupilot web page:
M1 - Throttle right (Motor) - Clock wise prop
M2 - Throttle left (Motor) - Counter clockwise prop
M3 - Servo right (Servo)
M4 - Servo left (Servo)

Please find the log and parameter attached in this post kindly help on this issue.

My H9 30cc spitfire next to club members TopRC spitfire. I sure do like the appearance of his Spitfire. This is my second H9 spitfire. Mine flies nice and smooth and when landing it just sticks to runway. The TopRC spitfire is gas powered and has problems with engine getting hot.

I extended the firewall about 3 inches and still needed about 6 oz. lead bolted to firewall.

Below is a link to my review on the Diatone Roma F4 LR micro long range quadcopter.

In this review I cover:
  • Discussion of specs
  • A look at the frame design and build quality
  • Betaflight setup
  • Flight performance
  • Battery options and flight time
  • GPS performance
  • Nebula V2 cam vs Nebula Pro
  • Final comparison to other micro LR quads and conclusions

This is a text and picture review, not a video review, hope you find it useful
