as i have a hard time disconnecting the plug of the servos from the receiver, i tried modifying hemostats. they are very thin and come in several shapes. 1 of them has curved tips, and are intended for handling towels. i ordered them and made some inserts to match the connectors. to me is the most practical solution. of course, this is not for all the guys that can do without specialized tools and dont need this.
i found this: http://www.ebay.ca/itm/MAK-Towel-Cla...8AAOSwr~lYqrFc


i trimmed the tips to match the width of the connector (7 mm) and cya 2 inserts made from 1/16" plywood.
filed/sanded to fit the connector tight. now they hold the connector the way i need.
from now on, i dont expect to have any trouble removing connectors anymore.
i hope this will be of help to some who, like me, are not experts that dont have any problem doing this.
first clipped the tips to measure 7 mm (the size of the connectors when closed to the 1st step), then added 2 small pieces of 1/16" ply that sanded to fit and glued them with cya and baking soda for fill-in. the inner sides are parallel (7 mm) and grab the connector when pressing to the 1st step. this way i dont have to worry at making pressure when plugging in the connector, just fit it.
am happy with the results, and i hope whoever makes them be happy too.
i think this is a convenient tool for all who deal with radios.

i posted this at the radios forum but i think here will have more exposure.

The real link between personality and well-being

if you want to be happy, consider that there is something you can do.
not only depends on how you are, but on how you face it and work on it. read this:

Which Personality Types Are Most Likely to Be Happy?
Your personality could partly determine your well-being.

We all want more well-being in our lives. But which traits are most likely to be associated with well-being? This is an important question because it can help inform our decision to cultivate some aspects of our being over others, and can even inform culture-wide interventions to increase societal levels of well-being.
But in answering this question there are some important considerations. For one, what aspect of well-being are we talking about? In recent years, multiple aspects of well-being have been studied that go beyond the stereotypical smiling and positive vibes associated with happiness (see here for a review). Here are 11 dimensions of well-being that have been systematically investigated based on three prominent models of well-being (Subjective Well-Being, Psychological Well-Being, and PERMA):

11 Dimensions of well-being:
High Positive emotions (high frequency and intensity of positive moods and emotions)
Low...Continue Reading

considering how most electric planes have to be prepared for flying, i was wondering why we need to open a hatch/canopy to connect the battery and take chances of having the motor started by accidentally touching the throttle stick.
even many years ago, when futaba released the first radio special for electrics, it had an arming switch that you had to press just before launching the plane, so you didnt have the risk of starting the motor by accident.
then, why we dont do it this way, that is an improvement on safety, but have to go through this pre-historic routine?
when i flew small r/c elecric planes i used a plug that closed the circuit of the battery and the plane was ready for flying. but when i got into larger planes, what i saw was that all do the plug-in battery removing the hatch. then i got this idea of using a larger plug, and started a thread here:
https://www.rcgroups.com/forums/show...-for-electrics
with the input i received, i got the idea of using a connector, not a switch, that could be plugged in, as i did with my smaller planes.
but this time not to the live wire, but to the radio itself, as this way it didnt have to handle that larger capacity battery. this way electronically it does not have to be larger. between the esc and the receiver. so i did it and seems to work. will try at the field when the weather allows and tell, but to me, it seems that it is o k. this is the 1 am using: http://www....Continue Reading

i was wondering how carbon, that is a particle like a small grain of sand, is available as strands, or whatevers very long fibers, or threads, so i searched and found how it is made to look so.
i hope it will be enlightening to you. it was to me:

i got this and used the DX6i with it.
it worked great, so am going to bring notes and details for whoever is interested on using the receiver, be with the DX6i, or with any other radio.
keep posted and search at the end for new details.
>>>there is a thread here:

>>>by results: will start with the field test to show what i got:
weather is full of surprises-some rare times good. today was 1 of those. i noticed that there was almost no wind so was able to field test the plus with my new 2 meters e sailplane (air intakes sealed to keep the motor and battery from cooling too much). near freezing, ice on the grass, but little wind at ground level, not much turbulence, but up there was some. enough to show the difference with or without gyro. i had the pots at 2 o'clock. also arranged to have the flaps switch set to some down elevator to compensate for too much tendency at climb. climb without it at start. once at enough height tried it. the figure was 25 (about 1/16" down elevator). learned it is not enough so will increase it. switches were gear ON, mix switch on gyro at climb so gyro was ON. once at cruise as it seemed stable, gear OFF-no gyro nothing. i could notice the difference. the turbulence up there made the plane shake a little bit, but could keep without it. another day with more wind will compare again. then turned mix...Continue Reading

with the increase of the use of the word "addiction" for drugs, over the past years, i decided to search for the definition(s) so we can find if it is the right word for our enthusiasm for our models (i mean, airplanes-or whatever crafts we like).
i found this:
1.- a strong and harmful need to regularly have something (such as a drug) or do something (such as gamble)
[count]
He has a drug addiction.
— often + to
an addiction to pain medication
an addiction to playing the lottery
[noncount]
His life has been ruined by heroin addiction.
2.-[count] : an unusually great interest in something or a need to do or have something.
(this sounds way better and closer to our hobby)

another 1:
Definition of addiction: Addiction is repeated involvement with a substance or activity, despite the substantial harm it now causes, because that involvement was (and may continue to be) pleasurable and/or valuable.

but wait: there is more coming...
ad·dict·ed
əˈdiktəd/
adjective
enthusiastically devoted to a particular thing or activity.
"he's addicted to computers"
synonyms: devoted to, obsessed with, fixated on, dedicated to, fanatical about, passionate about, enamored of, a slave to.
(that seems closer to our inclination)
i think i will settle for: "am dedicated to model airplanes". so will not be linked to addicted to drugs, or something bad i think.
after all, if you dont have some enthusiasm for something, life does not have a meaning...

once talking to a fellow about 60 years old, he said: "when i was younger"... and continued saying something.
that made me think that it is indeed the spirit.
otherwise, if you say "when i was young", that implicitedly tells that now you are not young anymore, and therefore you are old, isnt it?
and that does not help. your subconscious mind takes that straightforward, and begins to decelerate and increase your dowfall.
so, my dear fellow, never say "when i was young".
remember, you are as young as you think.
of course, you have to be aware that you cant aim at goals as ambitious physically as when you were younger.
like staying flying for so long. otherwise you may get tired and crash (i have seen so many folks doing so).
Ashley Montagu, the famed anthropologyst (who lived to 95 happy years), said that "the idea is to die young as late as possible". if in doubt, you should read his book "growing young". https://www.google.ca/webhp?hl=en&sa...ashley+montagu

this is especially important if you launch your plane by hand:
for all that i have seen, most guys just hold the radio with their hands. no strap nothing.
some use the strap. a few use a tray. even fewer a strap and a tray.
but those that dont use a tray, their commands are given with their thumbs.
lets analize each way:
1.-no straps: you have to use the thumbs all the time, as you are holding the radio with the other fingers.
if you want to move a switch, you have to hold the radio with 1 hand.
but if it happens that you need to correct something at that moment, you cant.
and if you try something, the radio may fall.
2.-straps: if you are using straps, it will not fall to the ground.
still, it falls out of your hands and the plane may crash.
3.-tray: with the tray, you will be able to move a switch without the radio falling out of your hands and loosing control.
and you can control the plane with your other fingers. like holding a pen when writting. you must agree that this way you have a more precise control. or you think that you can write the same if using only the thumb?
still, the radio may fall, but it is less likely, as the tray helps to hold it.
4.-tray and strap: now with the strap also connected, there is no way that your radio will fall. and you can correct anytime.
something like this: http://www.espritmodel.com/transmitter-tray.aspx
or this: https://hobbyking.com/en_us/frsky-ta...eck-strap.html
or if you build it yourself:
BUILDING YOUR OWN RADIO TRAY (9 min 33 sec)

and if you need to launch your plane, how you do when not using tray and/or strap?
no tray means you cant do any correction until your hand gets back to the radio.
think about it.
