Aircraft#26 of the Tengarang Fleet completed its mission at Livermore Flying Electrons Saturday 4/6/2019

[tengarang]

Six Aircraft from the tengarang fleet is gearing up for deployment at Livermore Flying Electrons. The mission is scheduled for the AM in conjunction with borntoolates Me-262 Dynam FMS 70mm 12 blade 4s twin setup. Weather permitting the mission is a go.

another alternative if you are in the SF bay area there is a open space where you can take off parallel to the parking lot by the water right off of 101 hw sierra point

[tengarang]

FYI For all the local RC Pilots in the bay area, needing a runway strip for your larger scale foamies, and can't quite afford to join a flying club or just can't make it out as often as needed to make a membership a worthwhile bang for the buck, there is a great place close by Menlo park shoreline mainly on Sundays at the following coordinates, feel free, to fly for free....

Runway pattern is counterclockwise off of Quarry Rd.

With some help from my friends discussing the replacement of the momentary switch. I came up with the following schematic and seems to work quite well. Since the output with 2A load is essentially a buffered 5V driver i chose a 5V relay (2211-05-301) to control the switch via GEAR channel from he transmitter .

https://www.digikey.com/…/co…/2211-05-301/306-1006-ND/301641

The 5V output was used to power up the relay and bias the Common pin 4 which is normally closed when the relay is not being driven 0V which enables Stewie to toggle tone each time i hit the gear switch.

when the relay is powered on 5V across the coil then the open circuit condition between pin 4 and 8 is met hence no tone toggle condition.

[tengarang]

Aircraft#1 Dynam GeeBee

I plan to build a ~4V audio amplifier to enable amplification capability to amplify Stewie's three tone speech patterns(s)

First thing that needs to happen is to have an auxiliary control to enable the controlled by toggle speech pattern(s) on Stewie's existing hardware which is already embedded inside the doll.

to do this i have ordered the
"Dr. Mad Thrust series 5A HV BEC with Inbuilt Aux Controlled On/Off Switch for Accs"
https://hobbyking.com/en_us/dr-mad-thrust-series-5a-hv-bec-with-inbuilt-aux-controlled-on-off-switch-for-accs.html

The Dr. Mad Thrust unit will serve two purposes:
1) tone toggle control
2) external BEC unit which will be decoupled by a 4000uF bypass cap which will be operable with the main esc's internal bec circuit as well; to safely achieve a dual BEC operational condition going to the receiver.

For the amplification circuit going in to Stewie's speakers the Texas Instruments the LM386N-1 chip will be utilized to build a circuit to amplify the sound from stewies 3 mode tone toggled by the Dr. Mad thrust Auxillary control.

At the moment i am debating to use a 9V or greater battery to get punchier sound at the expense of additional weight for the AUW (All up weight) of stewies airplane. Id like to keep the weight down hence the purpose of building this light weight circuit as opposed to buying a pre-built bulky and heavy sound module. Which by the way a custom built version will allow me alot more flexibility to retrofit the sound solution to what real-estate i have available inside Stewie's plane

In general im gonna use a 10K POT to adjust the input at the non inverting input pin of the LM386-1 and use filter caps at power to reduce clipping and noise tuning

the results should be better than most small blue tooth speakers......

went well as well, the taxiing surface at RSA is a bit rough for the super big motor fms 4258 650KV in conjunction with the 4000mah 4s China hobbyline pack.
Future missions for this aircraft will be flown at LFE with the smooth asphalt runway.

Both Aircraft#17 and Aircraft#18 received their high performance turnigy servos in the afternoon, for the elevator a qualification flight for these new additions will be scheduled

Aircraft 1,9 and 52 are on todays photo shoot. If tomorrows weather yields no rain with acceptable winds then the qualification for aircraft#1 and maiden flight for aircraft#52 will take place at Rancho San Antonio. Word on the street suggests De Porchetta B-26 will be on standby as presiding figure for the qualification and maiden flight ceremonies; and may also go upstairs for swim as well.

Weather Permitting.

If the rain does show up in tomorrow forecast then there is a indoor project for AIRCRAFT#17 and AIRCRAFT#18
for replacing both bomber with the "Turnigy™ TGY-390DMH High Performance DS/MG Servo 5.4kg / 0.11sec / 22.5g' servos.

Aircraft#43 Skyangle Screamer Pusher Configuration Via the Tengarang Method AKA also nick named "EDF Hunter" has undergone some empirical data collection comparing various prop sizes and pitch over a semi charged 4s 2200mah pack 25C Gens Ace.

Average Voltage Per Cell was noted around ~3.9V with 200mV in between cells before loading.

out of the various prop configurations exercised through this battery pack i have come to the conclusion the 4.75x5.5x2 APC prop is going to be the best choice in terms of maximizing speed and at the same time minimize power consumption. Note these numbers reported on the chart are representation of static (or Worst Case) loading. I surmise the amps will be averaged well below 35amp --> ~3/4 throttle when in the air since full throttle for this jet is not going to be needed throughout the majority duration of the flight.

The All Up Weight (AUW) is 1.34Lbs
and taking in to consideration minimum requirement for unlimited vertical performance is 150 watts per Lbs

which means for the given AUW we will need 201 watts to achieve the unlimited vertical performance.

Since we have 580 watts which means we have almost triple--> (~2.88) times the power needed to achieve the unlimited vertical performance...

The performance with this amount of thrust to weight ratio would be the secret recipe to ultimate performance; from a power to weight ratio point of view.

the 5.5 grade pitch will also ensure the high end acceleration will be topped out and sustained as much as possible even as the voltage under load is depleted through the duration of throttle application

Aircraft#17
1875mm B-17G Duchess Daughter of the tengarang fleet flown by myself in Formation with the B-17G China Doll flown by Captain Borntoolate and B-17F Blond Bomber flown by Captain Karltrek was a success.

Fortunately the three bomber crews were not hurt and the payload was delivered on target, however the other bomber squadrons in today's bomb group did suffer losses in a fierce battle with the axis powers while en-route to the target

Aircraft#43 qualification complete

I love this little hot rod!!!

[tengarang]

Weather Permitting if the rain stops i will look for an open window to qualify aircraft#43 "Skyangle Screamer 2800KV outrunner " with a Propeller: 5.5x4.5x2 pushed by gens ace 25C 2200mah and 1550mah 4s to get a feel of the characteristic how she will react to the new power plant and torque arrangement.

this thing was measured to be just under 600watts which would make this thing easily over power any modern large edf or in terms performance.

WIll be experimenting with smaller diameter props with more pitch to see exactly how fast i can clock this thing

[tengarang]

Final Taxi Test before maiden flight With LED's during the Early Evening of 2/9/2019

With a fully charged 4s 4000mah 45C China Hobby Line Lipo, she is drawing ~1200 Watts of continuous power at 82 Amps which results in ~mid to high 14V underload which i saw several hundred mV below the 14.8V nominal level for 4s. In practice i do not see this to be an issue as WOT (Wide open throttle ) will not be utilized.

The AUW (All Up Weight) for the USS War Cry is measured at 5.8 Lbs, keeping in mind the rule of thumb it takes 150Watts per pound to achieve good flight performance. In this case we have around ~200Watts per pound of power to carry the USS War Cry, and keeping in mind the IR drop will become lower as the load is eating away at the battery....

[tengarang]

Alright Guys and Gals of the tengarang Avenue.
I have an update or followup to make for my previous FB post to three of eight aircraft listed :

https://www.facebook.com/LordEmperorTeng/posts/10156854011524000

Aircraft#43 Pusher Belly Lander Fictional / Civilian Skyangel Screamer 2800KV outrunner.
Update: Installed the hobbywing 5V-6V-3A Switch-mode-UBEC, but instead of using the traditional tengarang method to source this external buck converter via separate 2s pack i am splicing directly to the main 3s/4s 2200mah power bus because i will run out of real-estate if the 4s 2200mah pack is installed. With a fully charged 4s pack i expect current draws to be under 55amps burst which the eflite ESC can handle, but now the external bec will give cot supply to the receiver step down to 5V, incase the internal bec to the 40A esc gives out due to over heating or over current condition. This pusher jet will undoubtedly out class any large EDF jet 6s and up simply because of the pusher configuration but very powerful Over ~500 watts at 4s operation on a slippery and efficient aerodynamic air-frame less than 2.8lbs, putting this little jet on another level of performance. It also will justify to prevent any further acquisitions for larger EDF jets in the 6s plus operation which helps cost retaining efforts for fleet operations. Maiden flight will be scheduled as soon as the BT3000 3.7V 1s Transmitter pack comes in the mail for the Devo 12s.

Aircraft#52 Tail Dragger Military/Fighter 11Hobby Bearcat 1100mm
Update: Receive the DSMX satellite extension to the open Receiver port and rebound to the 4258 F8F program on the DX9. Shes ready for her maiden flight

Aircraft#46 Tricycle Gear Military USS War Cry
Update: Worked on LED lights, which required some soldering work earlier today. All that remains to be done is to install these LEDS on board the USS War Cry. Since there are three days left before Sunday the 10th of January, i may have an open window to install these LED's right before the maiden flight. If installation does happen before the 10th of January, then there will be another update report with pictures to show the final implementation for Aircraft#46.
