I finally got back out for some slope flying today after a month layoff.
Due to lack of proper wind this past February was a complete bust ,last year when ever a North Easter would blow through the next 2 to 3 days would produce great wind 20 to 30mph straight up our hill,This year the wind after the storms has all been crossed -just when I thought I had the pattern figured out -
Anyway the forecast was for good direction 14mph coasting down to 12 mph by late afternoon so I left work a 1/2 hour early to be at the top of when the max mph was predicted to blow.

as on cue 3:00 found 15 mph steady gusting to 20mph...and Sunshine a pleasant surprise -

I had brought out a G.E.M.S Knife Edge - wide body, Of course A SIZZLE {all ways in my quiver} and My trusty Park Zone KA-8

The wide body flew well but as it was intended for lower wind conditions it did not penetrate and hold its inertia as well as my stock Knife Edge when the gusts ramped up,I had brought it expecting the wind to subside to 12 mph ....note to self - maybe a white wing is not the best color for snowy winter flying

The Sizzle was next - I spent a hour tearing up the slope with her,a kick in the pants as usual ADHD in all the right ways .

Then I finished the afternoon with a 1/2 hour on the KA-8, like dancing with a fat lady -
My fingers were starting to hurt so I brought her down and packed up,I hated to call it quits with daylight and sunshine,and wind remaining but probably the right call.
I Will sleep well tonight !

I think I found a wind-tunnel, a BIG wind-tunnel.
I was trying to figure out how to setup and document a KF-airfoil experiment tied to the front of my car without something breaking lose and breaking my windshield. Then I thought about indoor skydiving. Looked on Google-Maps for any indoor skydiving places near me in Los Angeles. Decided to investigate the iFLY Ontario. I talked to one of the managers and one of the instructors and instead of shutting me down they seemed receptive to my ideas. Like I said, I think I found a BIG wind-tunnel.
and their locator map shows 36 locations in the USA
and the Ontario (Los Angeles) location looks about like this.

Now I am trying to design experiments that donít cost a lot of time/money

Thanks for reading

Owie !!!!

My old body hurts !

Had to clean out a corner of my room , replace a old table with some tall boys ..

Oh dear , my body feels hammered .. Havent been this physically active since before the last time I injured my back ..
In fact , If I had attempted this a few years ago , I would have gotten a ambulance ride and a Hospital Holiday ..
It was a chore that needed doing . ( Bad back or not ) - Still need to do that oil change in my car ! ( But not now - the owie has to stop first )

R3 -

Went for the 3rd trim flight the other day after repairs and strengthening of the vertical fin / rudder .. CG was moved forward with a larger battery .
CG be 50mm from the LE now ...
Glides really nice , didn't do any further damage
Flying weight is right on 120 grams . Thats not terrible for a 1m HLG ...

Eachine Tx06 - Where is that DVR , I really want to record video directly .. My goggles dont have recording capability .
For a 25mw camera , it's rather impressive ...
I really want to play with it ...
It is on my WL toys V959 Quad , and it works really well , but the quad is not a indoor flyer ..
ANd the two micro quads I tried could not sustain the added current draw ..
The 959 has a 1000mAh battery , and there was no issue .. I recorded some 8 minutes of video .. ( Flight )
And the transmission was clean inside the house .. Other FPV set ups tend to break up - especially moving into other rooms , but the Eachine Tx06 .. Very nice .

Just posted a short Vid, showing a full "Body Shell" replacement...

In the process, I opted to highlight a few simple mods to reduce weight, such as stripping the LED Bezels, swapping in a light weight Dipole Antenna, ditching the Proprietary "Blade" power connection for a standardized Batt Connector, in my case I use HXT 3.5mm for everything... So now I have 8 batteries of various sizes n capacities to choose from for a flight. With the added bonus of NOT hauling the plastic Battery casing AND a USB charger circuit brd.

The factory 720p 25fps camera is long gone and the drone is now equipped with a Git-Up F1 90 4K camera with full Gyro EIS and other nice features

Although the video description does list the drone as an HS100 by Holy Stone, it is in fact a screw for screw duplicate of the Promark n SJRC models...

HS100 full body replacement w several mods (9 min 17 sec)

The Emax Tinyhawk is a 1s brushless whoop-style quadcopter that has steadily grown on me since I first reviewed it here. It's certainly not the fastest but is probably the most well designed ducted quad available at present. It comes stock with very good 3-bladed emax props that perform well except that lack thrust when running in reverse meaning "turtle mode" does not work. I've installed and reviewed their new 4-bladed props where turtle mode works and how they perform in general.

Read the rest of the article here including flight performance, weight, impact on efficiency etc.

Attached is a Tutorial on ex-mixers in FrSky's operating system for the Horus transmitter line. It includes an overview of the structure of an ex-mixer and uses examples to illustrate how the various features work. It also touches on the use of flight modes and curves, although those are not directly addressed.

For me the ex-mixer section in FrOS was the least intuitive and most confusing section. I decided that writing a tutorial for others was the best way for me to learn it and indeed writing the Tutorial has forced me to work my way through it. Hopefully this tutorial will save others at least some of the work.


EDIT: Attached is an updated version of the tutorial. This version adds Example #7 applying speed values to flaperon movement and a Function Flow diagram, as well as some minor wording clarification.

It's kind of hard to talk about these things and not sound like a total idiot, but I'll give it a shot. I live in the same town I grew up in about four blocks from the house of my childhood. But I fear I no longer live in the same country. As a veteran it makes me frightened to hear so many people speak about wanting to make America a socialist country, where does that even come from? I say that because the oath we took when we enlisted in service of our country is the same one that's most politicians take when they are elected to office to protect and defend the Constitution. I don't understand how anybody who wants America to be a socialist country can square that with their oath of office!
All though I'm relatively sure if anybody ever sees this that I'll be quickly informed how wrong I am and how toxic masculinity has clouded my thinking and what a bigoted fool I am. Just the ramblings of an old country boy Soldier who's trying to make a better place for my son.
by the way I am working on an 80-inch Cadet senior and I'll try to post some pics soon.

Anyway quick question guys, need to change battery in my x12, the 2000 NiMH ain't cutting it, I've noticed that rlink is 7-12v, will a 2S still work fine once it gets down to 6.4-6.6v?
Decided to test that for you. I took a 2S "transmitter" lipo and discharged it down to around 3.2V/cell. I also reset my Rlink TX to sound the voltage alarm at 6.1V.

Plugged everything in, and it powered up like normal.

I left it set at "low" power (~600mw!) and took a walk around the building with a powered and bound receiver in hand. It never failsafed.

Came back after three minutes, and heard the voltage alarm going off...

Disconnected and got the battery back on charge right away.

It is worth noting that the Rlink was still transmitting even though the input voltage was well below the stated minimum of 7V.

On 2 cells at 6.5V my Rlink TX puts out 610mw on low power and 720mw on high. With a fully-charged 2S battery the power output levels remain the same on low power but goes to 840mw on high.

I posted this in a thread but it's something worth putting here for posterity too. Hope it helps some of you.

ut in a flat line and wanted badly to actually dive into the work. It SEEMED like a good idea but was a total disaster.

On the other hand by far the most typical factory sharpening is the hard beveled shape shown in "B". I tried to show why this isn't a good detail carving shape in the second part of the sketch below showing how the hard heel will lever up the actual cutting edge. This makes it tough to maintain a nice flowing cut and doubly difficult to make a neatly curved hollowed cut.

The sweet spot is the apple seed shape where the part of the bevel that we use to guide the cut is immediately behind the cutting edge and the rest flows smoothly up and out of the way. This makes our lives easier when it comes to carving shapes and nice details.

Did some reading and learned about the better and more durable "apple seed" shape. But even there we walk a fine line between too blunt and edge to work well in soft balsa and too sharp which tries to act too much like "A" and wedge itself deeper too easily. Then there's the compromise of a finer angle which proves to be less durable and going too blunt and having a durable edge but one that needs too extreme an angle to the surface before the cutting edge ingages and a shaving comes up. Basically Papa Bear's knife, Momma Bear's knife and Baby Bear's knife....

I went down and...Continue Reading

Bought this plane from Aloft Hobbies, it was my first fiberglass /balsa glider. The build was not difficult but it seemed that way. The instructions were in Czech and bad English. I took my time and when I ran into something I did not understand I went to the web and searched. Most important I took my time to make sure I was doing it right. This was my first glider like this, most of my others gliders were foamies

I was some what apprehensive about flying this plane. It did not take much power to get this in the air. I was about 35% power and I was surprised it took right off with no problems and flew well. I did very little trimming. It is a great plane and fun to fly using 3s 1800 best fit
Aloft Hobbies great place to shop
