XK A160 J3 Low and Slow (5 min 16 sec)


Flying the J3 as slow as I dare ..
After the flight the battery still had 75% , so you know it was a low throttle flight .

I trimmed the LE Slats at the wing tips .. I am not sure , but they may have been affecting the Ailerons ( Making it harder to bank / turn )
J3 feels much better after the Slats being trimmed .

It flies slow .. Where was the death spiral ? I even stalled it , and you can hardly tell the J3 stalled .
I put the blame on the flight control board , because without it . ( There is no death spiral and stalls are so gentle they are hard to notice )

After my first video... knew there was a problem
because the plane was at the far top of the video,
and disappearing sometimes because the camera
was not aimed high enough. Shown is my 20 degree
riser block solution for keeping the model centered
in the video frame.

Mobius shows a hat rig on their website
without an angled visor mount.

So, after a few tries, I found a 20 degree
wood block, through bolted to the Mobius
mounting plate worked best for me.

Hundreds of videos later and this is my current
preferred setup.

The Mini was added using velcro. I can fly
the Mini on the plane or shoot a backup video
from the hat. The settings can be changed in each.
You could have the mini doing time lapse,
wide angle, zoom, or other settings.

All hats/visors fit differently so best to
calculate each one separately.

I've always wanted a small scale Spitfire, and finally had the bright idea to build one using the guts of my trashed UMX Yak-54 180.

Wouldn't seem to take too much work to create a profile Spitfire of the right scale and transfer the guts of the Yak-54.
Biggest complexity, I think, might be turning off the AS3X, or perhaps if I orient things correctly in the Spitfire it wouldn't make a difference.
Time will tell.

Time to dig out the Yak, take some measurements, and draw up a profile Spitfire.
Unless, of course, my EZ power plant shows up tomorrow, then all bets are off.

The EZ power plant did show up, so this project was shelved for a few weeks while I built the EZ F7F.
But I'm back on it now, and have created Phoenix models of both the Yak and the profile Spitfire to compare the flying characteristics.
Based on that, the Spitfire seems to fly fine at the same wingspan and weight as the Yak.
Considering making it a bit bigger, though, to give it more presence in the air. Need to give this more thought.
Next step is to generate plans for the Spitfire and then carefully transmogrify the Yak.

When I returned from my hiatus from the hobby in 2015, I discovered former major vendors were gone, new ones had arisen, and not surprisingly, one giant fossil was still here (Merriman….grrrrrrr!)

To make a long story short, my trusty D&E Miniatures WTC-3.5 suffered from spider cracks from storage in less than pristine conditions, and was subsequently leaking like a sieve (20-30cc in 10 minutes). This cylinder operated 3 of my boats with it’s adjustable ballast tank.

I freakin’ loved that thing. (and I do love Dave lol, rat bastard). He actually told me he thought I was the only one using that crank adjusted ballast tank sharing it on 3 models

But the electronics were outdated, and Dave wasn’t looking to rehash a 20 yo design, especially since he now worked for “the man”. Hey I dig it, I’m surprised any vendor can survive alone for long in such a niche market.

But I decided I was going to need to do more on my own. Focus on what works for me. After all, I had seen all sorts of approaches, done a few myself. Plus after stepping back for a while and entering the world of 1:1 scale Sailboat ownership, I returned with a new set of skills that can easily transfer over, most of which is surprising myself at what I’m capable of, second is that consistency and standardization is the name of the game.

I want to rely more on off the shelf products, one that’s not going to disappear when a vendor does.. I am going to standardize my approach. Pick what I like, and...Continue Reading

Used to pushing sticks in and down to arm your model? This video shows how to do it for models without a flight computer.
Edit: Using the sticks as the source on the logical switches avoids the rates caveat I mentioned in the video.

What you need:

A precompiled multiprotocol firmware file (.hex for Atmega328p or .bin for STM32)
A Flash from TX bootloader installed on an Atmega328p or STM32 multiprotocol module
A means to get the firmware file onto the transmitter's SD card
OpenTX 2.3.3 or newer
Copy the firmware file to the radio's SD card - it doesn't matter where you put it
Switch the radio on normally and use the radio SYS menu to locate the file on the SD card
Highlight the file and press the ENTER button
Choose Flash internal module or Flash external module as...Continue Reading

The 1st prototype had no showstoppers, just a few tweeks. The speed control buttons would be easier to reach if they were side by side. This would allow the power button to go in back. The height transition was messier than hoped. Throttle needs to rotate 30deg north. Pinky hook should extend the full height. Speaker hole could be smaller. It's heading to a dogbone.
