Silly question, of course you can’t…

My distance vision is now in pretty good shape, and bound to be better with the second cataract removed, but I still need a little help in close. The close and far replacement lens approach wouldn’t work because my right eye is super dominant. According to the eye doctor I need just a slight correction to get to 20:20 in my right eye, so I’ll have a little benefit from bifocals, progressives because I’m used to them. I got to thinking though, maybe some sort of wearable magnifying system would be good.

I went on Amazon and, while most of the lighted magnifying systems were standalone, I did find a reasonable selection of wearable devices. I chose two. First, I picked out a lighted headband with a selection of lenses from 1.0 to 3.5 diopters. The light has two power settings and it’s adjustable for angle. I believe the light source may also be useful without the magnifying lenses.

My second choice was a large, lighted magnifying glass with an adjustable neck strap and a built in standoff to push the lens away from your body. I think this will be useful for two handed efforts that could benefit from some extra light and some modest magnification.

I expect my first use for one, or both, of these will be rewiring the aileron servo connections in the Clipped Wing Cub I’m rebuilding. I have a build log you can find by searching my RCGroups name.

November winds, ENE to 25mph.

About the time of year for me to fly ... at sunset
with my LED loaded EPP foam flying wings.

Winds no problem for them. Also they land on grass
so no problem with wind direction or speed.

No 'runway' to deal with.

Will fly 3D planes and sport planes with landing gear
whenever we get calm weather. Should have several
Extreme Flight planes for 'first flights' then.

Brooklyn Dodger , a classic free flight model airplane from 1941 , designed by Sal Taibi.

I got it as a gift from Gary S. ( thanks ! ) , who got it from the original owner and builder Ed Walker ( thanks! ).

Wing span is 55in ( 1.4 m). AUW is 1250 g = 44.1 oz.

Converted to electric R/C , with Rudder, Elevator and Throttle controls.

Removed the old Tornado engine and added an electric brushless motor: 174 g , Kv= 800 RPM/V .

12"x6" APC clone propeller.

LiPo 3S battery 2200 mAh.

Full WOT current is 21A , but it flies ok with just 7 A.

I have been flying my 450 heli after installing a k-bar and renovating the heli with new updates.

So I bought a E160 from Eachine after seeing the Painless video. He was very excited about this heli.
I hope to get it by the end of this week...........

Rationale

Summer 2020 I installed a FrSky ASS70 airspeed sensor for test in my foam Parkzone Ka8b glider. I choose that one because the initial idea was to use it mainly in gliders and that one didn’t have a solid lead nose, and behind the foam was ample empty space (for the factory recommended hook servo that is very dangerous to use because it doesn’t allow release during failsafe conditions). After a few testflights I was convinced of the advantages of such a system if programmed to provide airspeed figures through my earphones to help me judge the speed in the pattern and thus enhance control of my touchdown points in the various gliders I operated. With age I noticed I was getting difficulty judging the speed of the various sized gliders and that cheap system could easily compensate that. GPS modules only provide groundspeed and that is utterly unusable in a moving air-mass (which we call wind). To measure airspeed you need to measure the amount of air that flows around your wings at any given time, independent from the air-masses’ movement versus the earth.

system description

The FrSky ASS70 is a so called low velocity/low precision system (still up to 270km/h) that costed only 34 euro and included a scale looking fighter-type pitot-static tube of 7cm protruding length, a lightweight sensor unit, a long flexible tube to connect total and static pressure between both parts, a male to male electric connector to the FrSky Smart-port entry in the receiver, and an...Continue Reading

CH 3530 Edge Retention Test (9 min 32 sec)


A) The 3530 is a fantastic fidget knife ( 10/10 )
B) Build quality is excellent ( 10/10 )
C) Lock up / Action / etc ( 10/10 )
D) The blade - At this price point I give credit to CH for fitting a decent blade on this knife ( Real D2 maybe - so people say )

It cut and cut and surprised me .. I would rate the blade 450-470 ish .. I set the bevel on the edge to 22deg ( 44 total ) and that's a little tighter than factory .
Factory bevel might be 25deg's or something .
So a knife I can be happy to own . Unlike some knives that only have D2 printed on a junk blade !
To date this is the 2nd best performer .. No1 was a Marttiini No7 and that was a 480 .

Now things are interesting !
I have another D2 Nemesis that will be tested shortly . ( The CH was not a nemesis knife ) The other was the Y-Start ... ( Spit - - - ping ! )

I have had a few people PM asking questions about a wireless PhoenixRC USB Dongle so ill do my best to explain everything here:

First well start of with software: https://www.rcgroups.com/forums/show...-for-PhoenixRC
this link well get you started in all software aspects and other goodies as well. Incredible community might i add!

Im using a DX8 Gen2

Now ill show my hardware. I had this already : https://www.amazon.com/Flight-Simula.../dp/B06X95JFJX I only used it for PhoenixRC so i kept the little switch on the side set to PhoenixRC. And then i found a pic showing where you could solder a servo lead to the dongle and add your own PPM receiver. I chose this as it was 8 channels which is the the maximum channels in PhoenixRC - https://lemon-rx.com/index.php?route...product_id=138
Keep in mind you can use 4, 6, 7 or 8 channel receivers but less than 8 you will have to activate things like gear and flaps from the keyboard. And the receiver MUST have a PPM output on it. Another example is https://www.amazon.com/Quickbuying-R.../dp/B0754L8WZ5

Pic 1 shows the setup and pic 2 shows where to solder. In my days i have only seen brown and black negatives on the servo leads so this gives you an idea . Once i had the Binding done(more on this later) i simply folded the receiver under the dongle and used a rubber band to secure it. I took a small needle file and filed away the dongle plastic case to allow the servo lead to protrude out and still be able to put the dongle case back together.

OR if your just starting out you can go this route and supply your own PPM receiver - https://usa.banggood.com/22-In-1-2_4...r_warehouse=CN

Added 2 pics to show final product

November 2nd 2020 -
Cold fronts are moving through, lake effect snow and dropping temps ... Time to put on winter gear and get out on the hill
It seems that slope season starts on my hill once winter begins to lock in - you have to play the cards you are dealt

I planned to be on the hill at 10:00 as the forecast predicted a 2 1/2 hour window of nw wind before shifting back to the west,I got to the bottom of the hill and began to suit up only to find I had left my bib coveralls back home ....I guess it's been a while since I was last out
Back home we go to pick them up - hopefully that would be my last dumb ass move of the day .

a hour later I am finally at the top the winds are a constant 22mph gusting above 30

I put the Coyote up first , nice to shake the rust off with a smooth flier.
I had her up for around 25 minutes ,by the end of that time my eyes were watering as I had neglected to put on my goggles so good time for a water break .

Next up was my heavy wing ,she is pretty stiff and cuts through the rough air with out a problem .
I had a blast flying close to the hill doing paperclips turns across the top and diving down the north side rolling into knife edge and blasting back up and across for another lap .

Finally I pulled out the "Sizzle ".
My right thumb was getting a little cold and I was tiered from being on my feet for the last hour, the wind had reduced to around 18mph and was starting to vector back and forth between nw and west .
It still amazes me how this 12oz wing can handle the gusts and chop ,she rolls like a drill and changes direction in the blink of a eye {if you want }
Always a kick in the pants ...

Hello good people!

TIP:
Whenever testing an Electric Power System, always have a proven and tested Electronic Speed Controller for this purpose and not just any ESC from the Hobby Drawer!

This happened to me when performing a Power System setup for test! I just reached in my Hobby Drawer and got out an old and un-tested E-Flite 25-AMP ESC, perhaps 10+ years old.

Using this E-Flite 25-AMP ESC, the motor (E-Flite Power 60 - 400Kv) exhibited some very strange things like squealing and reversing direction when I placed the throttle back to Null (OFF). It was so loud that I had thought it had a lose magnet or bad bearing!

Got a brand new E-Flite 60-AMP ESC and it now runs super smooth!

Cause: Bad initial (E-Flite 25-AMP) ESC used!

Attached pictures showing the good Test Setup testing my E-Flite Power 60 (400Kv)!

Here are some tips to improve your taxi skills:

*Use full up elevator so prop wash forces the tail wheel down to the surface.
*Use high rate and/or SAFE Off to increase servo throws to the tail wheel. Use SAFE On for actual takeoffs as any wing lifting can be automatically corrected as soon as it occurs.
*Use throttle very carefully as too much throttle can cause right yaw. Advance throttle very slowly to “break away thrust” then reduce just a little to maintain a slow taxi speed.
*Remove wings for practice so no accidental takeoffs occur
*Use aileron into the wind to reduce crosswinds lifting a wing. Use spoilers while taxiing to increase weight on wheels.

For Spektrum radios that have a throttle cut screen use the Throttle Delay feature in the Throttle Cut menu:
Change the Delay from INH to 5.0 seconds. Cut the throttle, advance the throttle to take off power, un cut the throttle (H switch) and concentrate on left stick rudder control. Reduce up elevator 2 or 3 seconds later and use prop wash over the rudder to maintain directional control. Once in flight the throttle reacts normally with no delay. For subsequent take offs repeat the same procedure.
