Dear Friends and Colleagues of the tengarang Avenue

https://www.facebook.com/groups/492907014419557/

I want to share the schedule for tengarang fleet operations in the coming weeks for the 8 of 52 aircraft in the coming weeks 2019. The aircraft order listing (from top to bottom) will indicate precedence of priorities. In general, priorities will change due to high commands internal daily logistics changes and fleet maintenance criteria

Aircraft#46 Tricycle Gear Military USS War Cry
Type of Qualification: Maiden Flight.
Note: LED lights will be retrofitted after the maiden flight

Aircraft#1 Tail Dragger Civilian Dynam GeeBee 1200mm
Type of Qualification: Re-trim the GeeBee with the new Bombay doors.
Note: a 2100uF bypass capacitor has been
installed due to the fact that the Bombay doors (2 additional servos) have been added to the Auxiliary network which I will use a Hobbywing 5V-6V-3A Switch-mode-UBEC powered by its own 2s source to capture any possible brownout conditions in case the integrated BEC of the ESC over heats or fails momentarily.

Aircraft#40 55mm Multiple Gears Civilian Tian Sheng A380
Type of Qualification: After the transplant of the V1 Orx Hobbyking 3-axis Gyro has made its transfer to the USS War Cry (aircrat#46) the Devo radio system was then automatically replaced by a new 7 channel Lemon RX with DSMX satellite now programmed to the DX9

Aircraft#43 50mm Belly Lander Fictional / Civilian Skyangle Screamer 2800KV outrunner
Type of Qualification: Re-Maiden with the Pusher Configuration with 3s 2200mah 40C. Will be observing how new configuration will behave throughout the throttle range.
Note: a 1600uF bypass capacitor has been installed due to the fact that the planned 4s operation will raise
the current draw level well above 40 amps for war emergency power which would put at risk the integrated BEC performance of the eflite EFLA1040U esc. A Hobbywing 5V-6V-3A Switch-mode-UBEC powered by its own 2s source to capture any possible brownout conditions incase the integrated BEC of the ESC over heats or fails momentarily.

Aircraft#52 Tail Dragger Military/Fighter 11Hobby Bearcat 1100mm
Type of Qualification: Maiden Flight, internal transfer from
De Porchetta's fighter fleet utilizing a FMS 4268 650KV
throwing a 14x8x4 FMS prop from the FMS 1400mm P-47D

Aircraft#31 Tail Dragger Civilian Eflite Maule 1500mm
Type of Qualification:3948 760KV (850KV measured via KV meter no load) to turn the 13x9x3 FMS 1400mm stuka prop with 3s

Aircraft#10 Belly Lander Military/Fighter Parkzone Wildcat F4F 975mm
Type of Qualification: 7 Channel Stabilizer qualification at LFE. The goal is to screen the rx itself to ensure it can handle the LFE interference tower recently placed as the rx had a bad antennae which i repaired. A DSMX satellite is installed to help with long
range reception.

Aircraft#30 64mm Tricycle Gear Military/Fighter EDO Model's Draken J-35
Type of Qualification: New 5 blade FMS fan installed to replace the 12 blade change-sun turned by a 4300KV hybrid outrunner
2627 size, a quick re-trim effort at LFE needs to be scheduled

Dear Friends and Colleagues of the tengarang Avenue.
Due to the weather washout this weekend, i utilized the grounded time to make some improvements to the USS War Cry and upgrade one of my skyangle screamers from an edf 50mm 10 blade coversion to pusher conversion via 2800KV outrunner from the changesun 64mm 12 blade setup which will be powered by a 3s 2200mah

Aircraft#46 USS War Cry has been retrofitted with the trustworthy non Auxiliary controlled Version 1 Orx 3-axis gyro, In addition to that some soldering work to shorten power cables to reduce weight and path resistance to the power electronics have been optimized. Hopefully next week i am able to maiden this aircraft

Aircraft#43 Sky Angel Screamer has received a 3s pusher configuration which generates 343 watts at 32 amps resulting in 10.7V under load
this will effectively make #43 the second fastest aircraft in the tengarang fleet

Aircraft#43 will receive an external bec with its own 2s source for 4s operation as well as the EfLA1140W Eflite 40A esc will run out of auxiliary headroom as soon as the underload current draw surpasses the 40A compliance in which case the external step down regulator will kick in as a safety net. With this configuration the 4s setup will be very much unnecessary as the 3s setup is already more than 2:1 thrust to weight ratio on a very efficient and slippery air-frame, 4s will just give this speed demon alot more power.

Dear Colleagues and friends of the tengarang fleet.

I have an update to share with the group about the modification efforts for the following aircraft(s)

aircraft#51 Eflite P-51D 1200mm
Received an upgraded motor from the Eflite Maule (Aircraft# 31). The 1050KV 15BL motor running 4s which gives 1260 watts at 99amps at WOT running the 10.5x8x4 stock prop. The advantage here was that the mechanical footprint of the motor matches exactly to that of the P-51 which shares the exact same motor casing and motor mount and xmount footprint to the firewall which completes the scale look.

The max power using a 4000mah 45C lipo with 3.83V per cell (before loading) yields 1260watts at 99Amps. In this case my seperate BEC which will be sourced by its own 2s 800mA lipo coupled with a 4000uF cap will serve as a safety net as the current rises over the 70A (80A burst) rating of the esc while the integrated SBEC of the ESC is most vulnerable to failure.

In normal cases i will not run full throttle, but only during war emergency situations will full throttle be utilized.

https://www.horizonhobby.com/15bl-1050kv-motor%3A-15m-maule…

Aircraft#31 Eflite Maule 1500mm
Received the 3948 760KV (850KV measured by kv meter)

https://www.motionrc.com/…/fms-1300mm-3d-plane-3948-kv760-m…

Running the FMS 13x9x3 prop. I have not measured the Power yet as i did not monitor it, but it is drawing less than 50Amps which i have retrofitted the hobbyking 60amp aerostar esc with reverse function. A handy feature when it comes to taxiing on the water incase a U-turn is not possible.

https://hobbyking.com/…/aerostar-rvs-60a-electronic-speed-c…

In order to get the reverse function working i have purchased a spectrum rx programmer for the AR636 because port 5 (Gear channel) of this receiver is pre-programmed to have port 5 floating which means it has no protocol to receive any instruction from the DX9 Gear Channel. I guess this is the way Horizon Hobby released this particular model consequently configuring this receiver this way, while other BNF kits like the eflite P-51 or P-47 or F4u have port 5 open to Gear channel. This is a minor obstacle to overcome but unexpected.

Once the cable arrives in the mail it should take no time to get port 5 active to the gear channel in which case the reverse function of the Aerostar ESC will come alive.

:Cool::) Yeah i get this alot....

i suppose i have John Wayne Flying TIgers film to blame. The Skipper often refers to his P-40's as "Ships" growing up its been ingrained.

But i know what you mean ...

Todays activity:

There has been some Re-Organization with in the Tengarang Fleet. I traded in three Vessels: aircraft 15, and 40, and aircraft#2 from the border control detachment for the For a BNF version of the Eflite 1200mm P-51D.

15 Tail Dragger Military/Fighter Durafly MK24 Spitfire 1100mm UK

40 67mm Tricycle Gear Fictional / Civilian TWM Nemo USA

2 Helicopter Civilian Chinook Walkera#38 USA

Up to date the tengarang fleet consists o 49 Operational aircraft with two additional aircraft under construction

aircraft#51 Eflite P-51D and aircraft#46 (former aircraft#48) USS War Cry

Aircraft#46 "USS War Cry" progress report update. The main length of the aircraft has been defined. the Under carriage footprint and layout positioning has been determined. Next step is to determine how the nose wheel steering servo should be placed to allow efficient and reliable re tractability.

More construction efforts will resume later this week as the gorilla glue sets.
