At first look, the 4-inch Eachine Shadow Field looks pretty good and with the coupon code: BG30SD4 you can get it for under 215 USD with DJI Vista.
The Long Rang Quad flies very well and with a long flytime. The modern 1404 2750KV motors have good, curved magnets. The HD version with the Caddx Vista is even available with the original DJI camera. The ESC's have 20 amps and the quad weighs only 158 grams. Unfortunately, Eachine has installed two bad components here, such as the F4 flight controller, which has a defective voltage sensor, and the GPS module with poor reception.

F4 STM32F405 flight controller
The F405 FC has enough serial interfaces compared to an F411 FC. But you can only use two serial interfaces with RX and TX Pad. Both interfaces UART1 and UART5 are already used with the Vista and GPS module. So you can't easily install a Crossfire or ExpressLRS receiver here.

image 1 - Here the repaired voltage regulator with the correct R2 1K resistor

The much worse thing is that you get the wrong voltage displayed on the F4 FC board. So you fly with a battery where you don't know how much voltage is on the battery. After a calibration of the voltage sensor, the correct voltage is initially displayed by a 4S battery, but if you connect a 3S battery, the voltage display is no longer correct at all. I checked the F4 board and I found out that the voltage sensor on the board have wrong resistors. The voltage sensor is on PC1, which is correctly assigned under resources (...Continue Reading

Cessna 165 Airmaster: In 1935, the economy was just beginning to strengthen enough for airplane sales to pick back up. Cessna had gone out of business several years before after the short production of the A series and DC-6 series. But as the economy Recovered, Clyde Cessnaís nephew Dwayne Wallace wanted to bring the company back. He designed the C-34 as an updated airplane to target the same market as the Cessna A.

The C-34 first flew in 1935 after Clyde and Eldon Cessna (Father and Son) joined with Dwayne Wallace and brought the company back. The C-34 was a four seat, cabin taildragger with a complex wooden cantilever wing. It was pulled along by a 145hp Warner which was later replaced with a 165hp Warner on most production models. The C-34 was slowly updated overtime into the 165 Airmaster, getting a center airbrake under the fuselage and larger tail surfaces.

The Airmaster was a very high performance ship for itís day with a cruise speed of 145mph. Itís wing was also a rarity of itís era being cantilever instead of strut braced. Cessna published a famous photo of people seated shoulder to shoulder on the wing from tip to tip to show the strength of this design. The Airmaster became fairly popular and had a production run of 183 airplanes. Most were sold to civilian and business clientele but when the war began a small handful were impressed into the military as UC-77s or UC-94s.

Today several Airmaster remain in private ownership (Around 20 active and airworthy...Continue Reading

Small update to my 59mm brushless nano. Switched over to a Mob6 canopy, and plastic hardware which led to almost a 2 gram weight reduction. Also decided to try out the HQ tri blade props. Love ripping this thing around the house.

Geez, I'm in of the stepper motors on my CNC machine quit working last week, and I couldn't cut anything out. Got a replacement stepper within a few days, replaced the old one, and the machine still wouldn't work....OK...then it had to be software, firmware, or the controller/shield (Arduino). Long story short....Uninstalled all the software/firmware and started from scratch with the most recent releases and drivers. Low and behold, the machine fired right up....But just in case, I have a new controller on the way........On the positive side, this is the first failure I've had since I got the machine in 2015 !

Meyers OTW: Allen Meyers began designing his light biplane in 1930 in his garage in Wayne Michigan. With his plans underway, in 1933 he secured a space in an old machine shop to get things really going. In 1936 the first OTW (Out To Win) biplane made its first flight.

The OTW was somewhat unique in construction for its size. While most two seat biplanes of the time had steel tube fuselages covered with fabric, the OTW had a semi-monocoque all aluminum fuselage. It seated two in tandem and was initially powered by a 125hp Warner. (Later production models were mostly powered by either 145hp Warners or 160hp Kinners) The wings were of a more standard wood and fabric construction.

In 1938 the OTW got official approval for use in the Civilian Pilot Training Program. (CPTP) The CPTP was intended to use civilian flight schools to train as many college students to fly as possible with the knowledge that many of them would eventually become military pilots if the US entered the war. The OTW was approved for this alongside the Ryan PT-22 and Waco UPF-7. Between 1938 and 1940 the CPTP used all three along with many Cubs, Aeroncas and Taylorcrafts to teach thousands of new pilots.

While the OTW never got an official military contract once the war did start, they managed to sell over 100 of them to various schools that were participating in the CPTP. This jump started the Meyers Aircraft Company which survived well after the war building civilian airplanes.

Today there are...Continue Reading

Hobbyzone Sport Cub S 2 (7 min 23 sec)

2nd trip to the field and 3rd flight .

Hmmm !

Expert mode is lethargic ! ( Aileron )
The S 2 is under powered for anything exciting .
What it does do really well , is fly SLOW - real slow ! Were talking sexy slow ! I think you could walk faster than the S 2's slow capability .
Intermediate mode is ?? ...
Seems out of place , Int is a wilder ride than expert mode ,,, What's with that ?
I would like for the S 2 to at least roll , and not into the ground !
That TT looks brilliant in comparison .
Got a serious ITCH for the S2 ? = Buy the Turbo Timber ( UMX ) instead .
I would lose no sleep if the S 2 was phased out of production .
In fact , I would love to see a Super Turbo Timber . ( Better than 1:1 power to weight )

Mounting the Dualsky GA6000.9 motor, painting the false radial engine, and mounting the cowl is what's in this next episode of my 92" Black Horse Gilmore ARF from MotionRC. Enjoy!

How to install the motor, cowl, and paint the radial - 92" Black Horse Gilmore Red Lion ARF - Build (10 min 26 sec)

"Pratt & Whitney supplied the powerplants, Wasp Jr. engines with 985 cubic inches of displacement. The factory beefed up and supercharged the engines with high-compression pistons and individual stacks for less back pressure. In 1932, the manufacturer rated them as follows: 525 horsepower at 2,200 revolutions per minute and 550 horsepower at 2,300 RPM when racing." - Wedell-Williams Air Service page 34

"The engine cowl for the Model 44s was a NACA-type provided by Hill Aircraft Streamliners. The full pressure cowl created a venturi effect at the trailing edge for the exhaust to exit the stacks. Turner's cowl tapered slightly more inward at the trailing edge than the other two. " - Wedell-Williams Air Service page 35

Rearwin 6000M Speedster: The Rearwin Airplane company began to falter at the beginning of the depression and Rae Rearwin negotiated control from his investors and started Rearwin Aircraft. The intended first offering of Rearwin Aircraft wound up being the third airplane to make it to production when itís development took a lot of work.

The Rearwin Speedster started life powered by a Cirrus engine. Initial testing for certification found the airplane didnít meet spin recovery standards. Between 1934 and 1938 the airplane received several changes in search of the solution. The ailerons were redesigned to reduce the gap between them and the wing. The tail feathers were enlarged and centering springs were added to the rudder. All of the control systems also received ball bearings.

By the time the Speedster was ready for production, the Cirrus engine was out of production so the Menasco C-4 was chosen to replace it. The 6000M was the final production variant of the airplane. It had a cramped cabin for two in tandem inside itís very narrow fuselage. It had a very distinct tough looking landing gear and large tail feathers. In general the Speedster was a very unique looking ship.

At the same time as the Speedster, Rearwin was producing the Cloudster and the Sportster. They seemed to overshadow the Speedster leaving it with a final production run of only 11 aircraft. Today two remain on display. The most recent Speedster to fly was restored by Tim Talen who was...Continue Reading

I put a stripped Gopro Hero 7 black on my Nanolongrange V2b design ( I was not sure if it will fly as it got pretty heavy at 131g. Still It worked out and now I'm pretty stoked. I think I can make it even 15g lighter. So stay tuned!

I started my jointer project. It was a mess this picture was taken after taking a coarse sharpening stone to the top for a good hour. It had a layer of rust on it that was beginning to pit the surface.

I could have opted to build a fixture and have the in and ot feed tables ground but I don't think it was worth the time and expense.

I ordered new knives and bearings for it.

Someone had been in it for bearings some time in it's past and was a bit brutal to it with a hammer. It had a couple of hickies on the cutter head from the attack.

The shaft was galled up a bit as well. Some file work restored it to functionality.

There are a zillion conversions out there for this type of chuck glider.

This conversion is intended for indoor flying and is based on a glider costing around $2 to $3 plus the various 1S components. I bought four gliders but they arrived badly bent. - you can see how I restored them here:

The motor is a cheap 8020 with a DSM2 servo-less brick and three nano servoes from BG in this case. The battery is 1S 205mAH DE and came from Micro Motor Warehouse.

There are control surface outlines in the foam but these are not large enough so I pushed the ailerons out to the start of the wing tip up curve and made the elevator full width and all slightly deeper. The elevator halves are connected by a carbon rod but anything stiff enough will do. The elevator control rod needs to be as light as possible however for the aircraft to balance perfectly with the battery full forward. The hinging is Blenderm but other tapes will work. The foam in this case is CA compatible. The wing saddle has a bamboo stick locator at the back and is held down at the front by the canopy.

Maiden flights OK in a light wind.
