Tip #26 - Using Low Voltage Components with Higher Voltage Power Systems




Here is a link to the Video:
https://www.youtube.com/watch?v=k2KLtIHp4Aw

My original intent with the RC conversion of the Chuck Glider using a Brushless Power Systems was for a 1S LIPO setup.
Needless to say, I could not get nearly enough thrust from a Brushless Motor & ESC to power this Glider on a 1S LIPO.
I had already ordered the Low Voltage Receiver & Servos, so now what do I do?
Well, I took the process I had used to convert an OPTO ESC into a Non-OPTO ESC by adding a Switching Voltage Regulator.
I still had a problem though, as I didn't want to use more than 4.2 volts (1S LIPO Voltage) to power these Low Voltage Receivers & Servos.
I remembered using some Adjustable Switching Voltage Regulators in the past to power things that maxed out at 5V so I used one of those and was able to complete the RC Conversion of the Chuck Glider using the Low Voltage Components I already ordered ;-)

I have received a few question on how I accomplished this so I'm providing this "Show & Tell" Tip & Tutorial and a Wiring Diagram that will help you do the same thing and allow you to provide no more than 4.2 Volts of power to these components while still providing full power to your Motor & ESC.

This is the process I used to complete the RC Conversion of the Chuck Glider and it worked flawlessly ;-)

I won't be posting any flying video's with dates from 2018 and on. Stuff from very early 2000's may be put here.

First and most importantly , lift up your stack!
Seriously the FC sits too low and is going to break a component off by hitting the frame from either vibrations or in a crash rendering the FC dead ...
The fix is simply to turn the rubber grommets upside down so that the longer part of the grommet is between the frame and FC.

Next if you intend using the 3s lipo I strongly suggest limiting your throttle to 70%,
More than that and people have reported that FC burns out, to be honest there is so much vibration from the props at high throttle on 3s that it is unusable anyway.

I did both of the above before flying and not had a problem, I prefer 2s anyway because I have lots of those 300mah turnigy nano techs 45c already and a 4 port charger for them. On 2s 300mah it is manifested fast enough as you can see from the video bellow.

Really gotta work on my blog, I don't like talking to myself so this is one of those things I have difficulty keeping up with.
As of so far I've done some fun builds.
Did a shark plane I called "sharknado" last year just for fun, but it didn't do well since I refused to make the fins 'wings" oversized for better stability I wanted to keep it more shark looking even tho I knew that would hurt how it would fly. It did fly like it was in a tornado hence the name.
The VX-30 concept space plane was an interesting build, ended up with three of them, tried my hand at edf with one of them, learned a lot about edf builds with that one.
The "Sprimbo" a blended wing that Mike Springer designed that I took the liberties of changing it up a little more to my liking...and naming it too...came out to be a pretty good flyer after a bit of testing and adjustments and with some input swapping with Mike. Liked it so much I ended up with three different variations of it.
And the latest is what I decided to call the JAC-1 "just another canard" plane. It's actually from a picture that I had downloaded a while back from somewhere that someone else had designed but may have not built one. Did some searching but came up empty so I decided to go for it with any info and built it based on the picture I had.

Just received from friends few samples of new great product CarboFlow. Very impressive quality for reasonable price is combination what I personally like) Density range is from 60g/m2 to fantastic 16g/m2 !!
Prefer to sell few first rolls as repairing kits by size 400x325mm approx to see how many people interesting. 60g/3 layers ($25 shipped) , 40g/2 layers ($20 shipped) and 400x300mm 20g/2 layers ($18 shipped) available. Also, have few smaller sheets 280x200mm of 40g/m2 and 20g m/2 2 layers($15 shipped)
Let's try and you'll be surprised) Note please, shipping cost was calculated to US.
Thanks

I bought my son the a959-b, after running it just a few minutes it shut off only the steering. Turn it off and back on it will run a few seconds and shut off only steering again. Anybody have this issue or know of a fix?

Next month is my 15th Anniversary on RCG and my 15th Anniversary of being back in R/C after 15 years off. While my available time to slope and DS has ebbed and flowed, I'm now self-employed and let's just say the boss is a DS addict too! I've recently pared down the hangar but still have a pretty healthy stable of slope and DS ships, a 3m Ellipse 3cam, a few foamies, and a yet-to-be maidened Explorer 2.5 for flat field thermal use. I also have a single electric plane, an HK EFX Racer.

Yep Les Amis,
Detected or not detected ? En route pour un 3eme vol avec le FIMI X8 SE ... Aujourd'hui je test sa vitesse de pointe en mode normal et en mode sport, plus deux autres modes de vol, orbit et spirale .
Je m'entête également avec le "precision landing" mais vous allez voir qu'en faisant des heures sup, tout arrive !!! lol . C'est aussi ma première vidéo Uploader en 4K, pour l'instant en 30FPS car le montage est plus lourd et difficile mais j'espère que vous serez satisfaits du rendu final. Je précise que je n'ai fais aucune retouches aux images du drone mais on perd un peu en qualité avec le rendu Youtube. En bref, je suis toujours aussi content de cet appareil qui reste pour moi, un des meilleur rapport qualité prix dans sa catégorie. Bon Film à Tous !
