I got sidetracked from the A-9 build for a few days cutting dividers for music genres. One of the original "dry goods" store on historic
Beale Street here in Memphis is adding a "Memphis Music" display for vinyl albums.

Feathers DLG , a look in the box (4 min 7 sec)

Came in the mail today .
Finally got one at a price I was prepared to pay .
Projected weight is high !
Also the Feathers needs building and covering !

I dare say that the UMX Whipit might be a far better option for 99% of the people .
It's lighter , it's built - add a battery / do a bind , set it up per instructions and go have fun .
And it's very close on the money , except that with the feathers you still need the stuffing ( Rx / servos ) , oh and to build the feathers .
Hmmmmm ,

Now that I have seen the feathers in the flesh ( well the kit ) , I would's highly recommend the whip .
Unless like me , you just gota have it .
Better bring your kit building A game for this one !
The better it's built - the better it will fly .

An alphabetical stroll through the history of aviation. Day 26, Z

Zenith Z6: How many biplanes do you know of that have seven seats? Probably not very many. The Zenith is in a very small class of large cabin biplanes.

The Zenith was built in 1927, a time when most major aviation advancements were made with biplanes. Zenith built the first Z-6 with a five seat cabin up front and a single open cockpit behind. Very similar to the design of the Boeing 40 series of biplanes. However the Zenith has a slightly more rotund look to it. The prototype was powered by a 220hp Wright but presumably didnt have great performance. The following 8 Zeniths (the entire production run) Had 420hp Pratt & Whitney R-1320s and carried six passengers up front.

There doesnt seem to be much history on what exactly the nine Zeniths that were produced were used for. However the history of the one survivor has remained. It was used by Bennett Airlines in Idaho unil it was eventually converted into a crop duster by replacing the front cabin with a hopper. It was found in this condition and restored back to airworth condition which it remains in today on display at Creve Coeur MO....Continue Reading

Got a new lens this one is a 12-24mm F4 G so trying it out. Was lucky to get out to fly it was 62F a bit cold but there are thermals in winter. I caught some thermals... I read/watched the wing's default shape (no flapperon movement) is in speed mode, so the cruising/thermal mode is some millimeters down. So yeah... it was a great day almost no wind later on. The flat sink rate was nuts my AUW is 8.4oz and was able to do 2 minute flat flights in dead air from a launch. That's if you seldomly turn, just keep it flying flat most of the time.

No video, nothing interesting to show but also the weeds were in the way, most of the time the 12mm was too wide/plane is too small in frame. I also need to remember to buy some spray for my head, these gnats were brutal just chasing me around.

Hoping for a better weather day, one day a friend will help me film it.

Yeap, still looking unpleasantly thicc to need to diet, start lifting again.

Update next day

Made a 16g ballast from a dead tube battery. Was able to launch/fly a boomer, sadly I did not film it, (didn't check camera was recording doh)... did film today, will post video.

An alphabetical stroll through the history of aviation. Day 25, Y

Yokosuka Navy Type 3: Yeah, thats a mouthful. It can also be called the Avro 504 and that is much easier to spell.

In WWI, with all the fun rotary powered fighters around, there was a need for boring trainers. Avro answered the need with the 504. The 504 was powered by a seemingly endless list of engines and was also built under license by several companies. Over 10,000 were built throughout its production lifespan.

The Japanese variant was license built by Yokosuka. It was identical to the Avro in the airframe department, it was just powered by a japanese engine. At first they were powered by en english motor as well. A version of the Armstrong Mongoose that was license built by Mitsubishi. Eventually it was replaced with the Gasuden Jimpu 2 160hp radial.

Maybe not the most noteworthy airplane in the world, but there was actually 464 of them produced....Continue Reading

My PineCil soldering Iron arrived today. Not a bad delivery time, bought it on the 18th so just over 3 weeks to get here.

Nice little smart soldering Iron. It doesn't come with any cables and just one tip but it has options for USB-c and a DC jack. I was able to hook it up to my Nokia QC charger at 12V and my battery charger power adaptors DC jack at 16V and both have worked perfectly. On the 16V power brick it got to 350 C in less then a minute.

The tips are standard TS-100 style tips and its really comfortable to hold. Its even designed for the case to be removed and there are 2 other cases available, red and clear plastic. It has an earthing point on the Iron as well.

Good menu and plenty of user controls including a sleep timer and an auto shut off.

Really happy with it so far. Now I just have to give it a good run to see if it will be worth using as a daily driver or just a small toolkit type iron.

EZIO 800 (6 min 25 sec)

A) Love how it looks - that's where the love ends !
B) The nose should have been longer , so that folks could have a battery choice
C) As designed , almost impossible to make CG without lead in the nose .
D) I had to make a custom battery that barely makes it into the battery compartment . And my CG is still rearward .
E) Still needs more nose weight , brass prop nut ? . steel maybe ? ( ill have to check that ) CG needs to be further forward .

The EZIO hunts up and down because of the CG , is super sensitive on the elevator . The build quality on mine was So So and I needed to do fixes .
Still . looks damned good in the air ! Been over a year since I last flew it . Just could have been better .

We are making available for immediate ordering our larger (30" wingspan) interpretation of the Leadfeather 3D Delta including a KF4 airfoil (theory) which not only gives the plane great flight characteristics, it also strengthens the wing significantly. We have increased the fuselage thickness to 15mm EPP to strength it. The KF4 airfoil (image) complicates the wing building over and above a typical flat foamie. (but the end results are well worth it)

Also, you should be aware that the build uses more than 2oz of Foam-Tac to complete.

Check out the associated flight videos on our 3D Delta XL playlist as well as the full instructions online

If you own or are looking at owning the new WL Toys 104001 1/10 scale RTR 4wd buggy and want to get better performance out of it before you consider modding, then I've put together a tuning guide for the key areas you should probably address since they are poorly adjusted from the factory:
  • Gear Mesh
  • Diff oil (not grease since they use sealed diffs)
  • Getting shock fluid set to the correct level
  • Tierod adjustment

This has lots of images and steps laid out in a simple way so beginners can follow too. I've also covered off a couple of ways this car cannot be adjusted where the 144001 could but spoiler! It's not a big deal.

There are of course shortcomings on this car but as usual the community will overcome this and make it into a decent bang for back option. It is after all heavily inspired by the Xray XB4 2016 which is a pretty handy car.

This 1st PETG wheel got some farsteners to keep the tire in place. PLA looked a lot better, even when it was melted. The wheel is still a disaster to glue together. The rings were finally printed as C's to make gluing easier, but they always deform.

Then, there was a PETG motor plate. It was rigid enough to do the job, but it became clear that it was better if the motor plate melted before the motor destroyed itself. The PLA motor plate was a fuse.

There is a vision of bolting an aluminum sheet between the motor plate & motor to try to cool it. There just have to be large holes for the shaft & wires. It might have to stick behind the motor.

Then, there's reducing the tire diameter all the way down to 70mm. RPM would have to increase by 108/70. Wheel diameter is constrained by the size of the motor shroud which is constrained by the size of the motor legs.

E-Flite Valiant 1.3m BnF Basic

I decided a while back that I wanted some good high wing taildraggers. Probably the main factor in my coming to that conclusion was the Hobbyzone Aeroscout with a nose wheel. Crashing it or even very rough landings often leads to cracking the fuselage or breaking the nose off. I have probably had to repair the Aeroscout more than 6 times because of damage caused when that nose wheel hits the ground wrong. So after some research I bought the Night Timber X. I have not flown it yet, just finally got it paired with my Spektrum transmitter yesterday because I am new to Spektrum and there are not really any easily found complete instructions on binding a receiver to a Spektrum transmitter. I spent several hours searching and studying how to bind it and finally put enough information from different sources to get it to work, but the Avian smart esc may not be working right, so no motor reversing. Spektrum transmitters may be good, but binding, programming, and setup is not simple. I have been using Detrum transmitters/receivers, and they are more user friendly.

So after reading both Night Timber X threads all the way through, I wanted something else to read, and found the Eflite Valiant thread, another BNF high wing tail dragger. Reading about it made me decide it might be the next plane to get. So I thought if I wait a while, maybe there will be some kind of sale on it. Friday or Saturday I got an e-mail from Horizon...Continue Reading

The cheapest way to try to reduce the overheating motors was by shrinking the wheel diameter to the smallest possible size. 74mm was disappointing. Maximum speed was reduced to 8.5min/mile. Hill climbing with a payload was slightly faster. It was noisier. It was really noisy with a payload, because the internal structure of the tire created hard points. The mane problem was the low ground clearance. The motor modules got really chewed up. The minimum ground clearance seems to require 108mm wheels.

74mm wheels work for skateboards because the only exposed part is a narrow shaft. They steer by rotating the entire shaft of the front & back wheels. Since only the traction wheels have to be small to provide enough force, the front wheels can still be 108mm & have all the steering hardware. The motors in the rear have to be fully enclosed in the tires with only narrow shafts joining them to the chassis.

So there's still a problem of overheating motors as the weather warms. The latest theory is to invest in 1/16" sheet aluminum. Manually cut out hubcaps to dissipate heat out of the hubs. Manually cut out strips to dissipate heat from the motor legs.

Making those 74mm wheels was a lot of work, but it was still infinitely easier than before 3D printing. 20 years ago, it would have entailed many days of cutting & grinding or wouldn't even have been possible. A younger lion did spend many years on robots where a big part of those years was spent manually creating parts that could have been spun out by a 3D printer in days.

This thing is a beast!

Mike Patey's HUGE E-flite Draco RC Plane Unboxing & Overview (8 min 18 sec)

E-flite Draco BNF Basic Review Notes:

- Working suspension in the front & back landing gear
- 4S-6S battery options
- SAFE/AS3X Receiver with the BNF Basic version
- Many different light combinations
- Carbon fiber added all over for additional strength
- Reasonably quick Foam RC Airplane build time
- ESC works well with Spektrum Smart packs & lets you know if your flight packs are not charged enough to fly

- The tail section is sloppy for a plane of this caliber
- Horizontal stabilizer could have used screws instead of just a click in setup to ensure strength
