In this tutorial we take a detailed look at how information flows through OpenTx radios. Specifically we'll examine Inputs, Mixes, and Outputs. Based on comments and questions I see in the other tutorial videos, this is a highly misunderstood dark magic in OpenTx and we're going to shine a light on exactly what is going on.

Then, it was time to rebuild the transmission. The mane interest was applying a new grease to try to reduce the noise. After at least 15 years, lions finally narrowed down the ideal lubrication for plastic gears to silicone grease. It's not sold in the lubricant sections of any stores. It doesn't show up in any searches for axle grease. It's only in searches for plumbing grease. This is the transparent grease used in plastic toys & plastic servo gears. The key ingredient is Polydimethylsiloxane.

I started Scorpion Calc kernel in 2002
Now, in 2020, it is time to present some "insides" like a bonus.
First chapter about the permanent magnets brushless motors (PM-BLDC)
In 1997, I started to participate to "miniature RC solar cars" challenges with small DC brushed motors (Portescap + integrated gear-box)
In 1998, I started a first calculator (under Visual Basic) to find the optimum gear-box ratio, taking into account the resistive torque.
I won (easily) the challenges up to 1999, when suddenly, in 2000 a competitor beated me in max velocity !
I asked him to show me the "under body": he was using a small brushless Astroflight motor (+ gear box) but had some difficulty to start from stop!
After some readings, I decided to try also that solution (BLDC) in direct drive.
Rapidly I found that a low Kv was mandatory and began to wind some small BLDC coming from PC CD-ROM
I was learning about neodyme magnets to replace the ferrite original poles
and about the number of turns acting on the Kv (rpm/V)

Yep Les Amis,
Piloter un Hélicoptère ... TROP FACILE ! LOL ... Avec ce test, je réalise un peu un rêve. Comme vous le savez, piloter un hélicoptère RC digne de ce nom, n'est vraiment pas à la portée de tous, et bien avec ce FW450 de FlyWing ... si ! Ce pack RTF va permettre à tout le monde de pouvoir se mettre aux commandes d'un hélico sans risquer de le crasher et de perdre son investissement. Les finitions et matériaux utilisés sont de très bonne qualité. Les deux réglages à effectuer sont simples et l'assemblage rapide et facile. En bref, je suis tombé sous le charme et je compte bien l’équiper d'une caméra FPV pour encore plus de sensations ! D'accord c'est un investissement, mais la qualité et le plaisir sont au rendez vous et ce ne sera pas de l'argent perdu pour tous les passionnés d'hélicoptères qui n'auraient jamais osés se lancer dans l'aventure . Bon Film et merci à tous pour votre soutien .

How would you like a free 120w Smart LiPo Discharger?

Kacallap sent me a couple of their α12 LiPo Battery Smart Dischargers. One for review, and one to give away on my YouTube channel. So far I've discharged three batteries on the demo unit. 3s peaked at 8amps, 5s peaked at 6amps, and 6s ran steady at 5amps.

The discharger brings packs down to about 3.78v/cell and it does have a balance lead connector, so it is watching the individual cells during discharge. Once it gets down below 3.8v/cell, it reduces the discharge rate and the cells start to recover. The three packs I've run through the process all came off at about 3.83v/s and after resting, they all hit 3.84-3.85v/s.

The fans move quite a bit of air though the discharger and across the heat sink which runs longitudinally through the case. It is a fairly hefty little box indicating a robust heat sink. I took temperature measurements of the heat sink fins while discharging a 6s 5000 and saw 123F.

There are no discharge options. You connect the battery and press the go button. The discharger handles the rest. It also has an auto-shutdown feature post-discharge so you don't have to worry about your battery powering the discharger after the discharge cycle is complete.

The unit does meet the stated 120w discharge capacity, it feels robust and weighty in the hand, has a strong aluminum enclosure and a decent--but not great--backlit lcd screen. That's the one area for improvement: The screen needs to be brighter. The information displayed on the screen is useful and includes the main voltage, cell count, discharged MAH, and per cell voltage.

Overall, I'd say it's a strong entrant in the Lipo discharger market. Watch the video for more info.

U.S. buyers can find the Kacallup α12 discharger on Amazon:
Non-U.S. Buyers: Please contact [email protected]. Kacallup will send units directly from the factory in China.

R03 Mini Stick with 18650 (1 min 24 sec)

Yeah , 5 1/2 weeks to go till I can fly the R03 Mini Stick .

I put a 6x4E prop on and CG is much better .
All that needs doing is making a hole and tightening a screw . I have 5 and a half weeks to take care off that .
