This is Mobula6 ELRS with 0702 26000KV motors that is flown with two blade propellers. A great 65mm whoop who can do freestyle well with super good video reception at 25mW. Thanks to the ExpressLRS receiver on the board, the Whoop has a great range without failsafe. Over 400 meters range and that with a 65mm Whoop!

Heat sinks went in on

May 20 & worked well for a few months. Then came another case of a screw coming loose, the encoder going out of alignment, & the motor stalling. It quickly overheated & melted the PLA, feeding back into the stall. The heat sink was initially only slightly warm. The good news is the heat sink quickly got hot. It definitely took out some heat. The motor cooled down more quickly than it did without it.

The lion kingdom stopped using PETG because it's heavier than PLA & it requires enormous heat to print. The melted PLA has never permanently killed it. What's really needed is a screwdriver which can tighten the screws in the field. Those screwdrivers are gigantic.

There are some really ignorant individuals who frequent forums. The fact that they get banned from other forums - doesn't seem to change their attitude or ways.

You try to accommodate - you go the long road to accept their way of doing things - pointing out that their way is theirs and others have their ways .....

Its a wasted effort .... they keep plugging on ruining good threads - oblivious that literally no positive replies to their self-indulgent posts and videos ....

I understand that the larger a forum membership gets - the likelihood of such idiots increases ... but it still destroys good threads and makes for moderators headaches.

Anyone reading this - I am sure know exactly which idiot I am talking about ....

Lumenier's Double AXII FPV antenna is able to effectively more than double the gain of a standard AXII 2 antenna from 2.2 to an incredible 4.7dBiC. The results are close to a patch antenna despite providing omni-directional high gain!

Dogs have been owned and through genetics/breeding you have the 100s of breeds we have today...

The cat? Not so much. Relatively a new comer to indoor living, it's more of an arrangement. You hangout and kill of the rodents and I will give you a place to stay and food. Other than that with the exception of a few breeds they are the mammal version of a shark.

It wasn't all that long ago if you were found the be the keeper of a cat they would build a fire in your honor and roast YOU for being a witch.

A feral cat and I'm talking house cat size could tear you up bad if it had a mind to.

I was in the yard with my morning coffee, my cat likes to sit with me and it hit me, I'm harboring a midget mountain lion...

Top is my cat Goose, the bottom is a picture of Messi, a mountain lion living as a house cat. I hate to say it but Messi is the more domesticated cat.

🧐Yep Les Amis,
Sérieux concurrent du TBS CrossFire ! ... Comme je vous l'avais promis, voici un petit tuto, ainsi que quelques explications et conseils, sur l'Express LRS de chez BetaFPV. Cela va faire environs 1 mois que j'utilise ce nouveau protocole Open Source et je dois avouer que je ne lui trouve pas beaucoup de défauts pour l'instant. Une latence imperceptible, une portée impressionnante pour un prix beaucoup plus abordable que son concurrent direct, le Crossfire... Bien sur, la plus grosse difficulté pour certains sera d'être obligé de passer par un PC pour la mise en oeuvre mais nous savons maintenant que dans notre hobby, c'est pratiquement indispensable pour beaucoup de paramétrages. En bref, pas cher et efficace, que demander de plus ? ... Prenez soin de vous (et des autres) et merci à tous pour votre soutien .

Using my latest scratchbuilt foamy I am learning to fly high alpha. Not much luck yet but is fun learning. Need slofly prop and maybe to move CG back a bit more. Anyway, onward and upward.

Update 9/20: was too nose heavy so moved battery back a bit and wow, flies pretty cool. Can even land without hitting nose. Can use the rudder a bit better. I found out that if the plane is nose heavy and I use the rudder, it dives almost uncontrollably. But with CG moved back a bit, the rudder works well in concert with the ailerons. Doesn't roll as beautifully as before but I need to learn to fly high alpha anyway. Take my hands off the controls and the plane just flys straight and level. Nice. My batteries are in bad shape but leaving for an island soon so will have to wait on new ones till I return. Anyway, it was fun to make a little progress towards learning 3d.

So I had to try and rid myself of unwanted weight ..
So I tried a print without a top and bottom surface .. For a open frame .

weight = 19.36 grams ... That's just for the PLA

Grumman Guardian: The Guardian may be one of the most aptly named airplanes in history. Built for anti-submarine patrols, the Guardian was built to be the coastal guardian of the US.

In 1945 Grumman had just completed a new torpedo bomber called the XTB3F-1S. (I know, catchy name right?) The XTB3F-1S had initially been designed to have a big radial up front and a jet engine in the fuselage. But when it became obvious that the jet engines would never be delivered on time, they scrapped the jet portion of the project without ever having used it. The resulting airplane was a two seat, side by side, R-2800 powered torpedo bomber that could carry 4000lbs of explosives.

Just as Grumman completed the testing, the Navy changed its mind and decided they didn’t need a new torpedo bomber, they needed a new anti-submarine aircraft. Since the Guardian couldn’t carry all of the equipment for this task, the “Hunter/Killer” pair was born. In one of the coolest adaptations of a military airplane ever, the Guardian was adapted into two very different airplanes. The AF-2W “Guppy” was the “Hunter” and carried an immense radome underneath it with sub-detecting equipment. And the AF-2S “Scrapper” was the “Killer” which maintained the original bomb bay for carrying anti-sub explosives.

As the “Hunter/Killer” name implies, the two airplanes would operate together in a team. The “Hunter” would fly along with a “Killer” in tow and search for subs. If one was found, the “Killer” would move in...Continue Reading

We are still in perpetual LOCK DOWN ( Thank you Dangerous Dan )

How much longer ? Christmas maybe ( Xmas to some ) ...

So off to Thingiverse I go ...

There be this wing that I been thinking off .. Printing .

So far today , I printed out the centre section @ 20% infill , and it's a brick ..
So I am doing R2 with some design changes to better
A) Accept a 949 flight control board
B) Accept a 8520 brushed motor .

I will back off on the amount of material used , maybe 10% infill .. As the print came out very strong ( overly strong perhaps )
So I will start a new print ASAP

Check out the other posts in this thread .. ( Contain updates )

There is a plan forming to replace the current fleet of 3 cell batteries with 4 cell batteries of varying size. There would be 1Ah, 3Ah & a 4Ah. 4 cells are believed to have more range per Ah than 3 cells. The mane reason for a 1Ah is for trips under 2 miles. It's a lot easier to lug around a 1Ah than a 4Ah. There's still a desire to use a phone for 1 more mile. It would be charging the traction battery in USB host mode or it would have a direct battery connector soldered in. A phone equals a 4cell of 660mAh.

No matter what, the voltage is going up to 16.8. It takes a lot of volts to run a direct drive motor.

It should be noted the lion kingdom tried rubbing the electrodes together from a battery which was discharged all the way to 0.5V. There was rubbing lithium on graphite, lithium on lithium, & graphite on graphite. They never exploded or got hot. Part of the trick is it was all the way at 0.5V. Big clive had the electrodes burst into flames, but his may have been only down to 3V.

The experimentation on Lipos that abounded 15 years ago is no more. Even electroboom never bothered with lipos. Sometimes, it's not the danger as much as the fad.

My first assembled-myself and not bought second-hand RC plane was a Great Planes Trainer .40 in the early 1980s. I eventually "re-kitted" the plane--accidentally--and have kept most of the balsa all of these years. I've made it a point to use a bit of it in every plane I've built since then, about 50, I suppose. Even my foamys get a balsa gusset, some hinge reinforcement, or a bulkhead doubler from the old Trainer.

Silly, I suppose... but memories are worth the saving.

Hi friends,

Just starting a project and thought i'd write out some notes.

The goal is to figure out how to get a plane like the Eachine GA202 manufactured.
The electronics on these little planes are perfect and I would like to learn how the receiver boards work and try and make my own versions.
I'm decent with cad modeling and plan to design my own airframes as well.

I've looked into prototyping these frames but haven't found much information on what is it polystyrene expansion? you get a mold and pour tiny foam beads in it then shoot steam in there and they expand and stick together. But no videos, no diy, not much i can find.
Also saw a guy that vacuum formed like one mm thick foam in a mold for an ultralight but that would be too fragile.
