The functional diagram of the autopilot is shown on a picture. The heart of the autopilot is the LEVEL1 block. This module is a high-priority function and is executed independently of other events every (15.625 ms tested version) 46.875 ms. Its task is to keep the aircraft in the correct flight position.

Description:
The input data for the module is the FSSi structure, which contains the parameters Roll, Pitch and Air Speed. A correct flight position we will name roll = 0 and pitch = 0, when Ref signals are absent. Also this module controls the engine controller of the aircraft and ensures the holding of the speed received from the LEVEL2 unit in accordance with the flight task. The Level2 module disturbs the LEVEL1 module by the Ref signals and thus forces it to hold non-zero roll and pitch values that calculated in accordance with the flight task. The speed parameter is directly transmitted from the flight task. The output of the module is a data structure that contains the current position of ailerons, elevator, rudder and rudder (Throttle). This structure in the program is called FSSo, the Module has the name FltStSys (flight stabilization system). It can be fed into the PWMC (Pulse Wide Modulation Controller) if the autopilot mode is activated. Otherwise, a structure filled with a timer is sent to the PWMC according to the measured values received from the HF receiver. This is a traditional control mode for radio-controlled models. The Level2 module is slower, it generates...Continue Reading

Feilun FT011 Brushless Race Boat Unboxing (7 min 13 sec)


I'm excited about this unboxing because it's another brushless RC boat! You know how I was shocked by how much fun I had with the Atomic Barbwire 2. This one is brushless as well, but bigger. It's the FeiLun FT011 brushless and watercooled RC Speedboat. It comes in at a great price. Can't wait to run it and get a speed test for y'all.

Before buying the Mavic Pro, I was intrigued by its “Active Track” function, thinking that it can follow my plane around. It turns out the AT function works quite well tracking surface moving targets. It fails quite miserably at tracking airborn targets, with changing of back ground from ground to sky, sudden and fast moves of aircraft, especially changing flight phase, ie. takeoff, landing, maneuvering etc. The only conditions where it works tracking a airborne targets is when the target moves in a very benign manner with little altitude and angular change relative to the drone, essentially mimicking how a surface target moves. So if anyone is considering buying a Mavic Pro to autonomously film aerial footage of planes, don’t!

Here is a successful attempt after dozens of tries following a plane through takeoff. Any closer, the angular change would be too great for AT to follow:

Welcome to my Blog,
I wanted to let everyone know (and especially those with current orders) I have recently donated my pilot figure and R/C products production(Benchmark R/C) to a non profit company called Build-Up Services Inc. It has been a little confusion and delays in shipping while reorganizing and getting the shop equipped and in order for these changes. This company is an employment service company for Disabled Veterans, and other individuals who may be disabled or challenged to work in a standard workplace scenario. I will be assisting them in training for production , painting, and sales. I have found some very capable and talented Disabled Vets...and think they will become a great opportunity to make this company thrive.
Build -Up Services is also involved in "Faith-Based" counseling, food assistance, and whatever other needs we can help, besides just supply a job. For those who risked it all to secure our freedoms here in the USA thank you . This is the least we can do to support such a worthy cause.
As we transition into a stable workforce we will be posting updates on our website[U] https://mhartfab.wixsite.com/benchmark-rc about Build Up Services. There will be links to help support our DAVs and gift offers as well.
We will be implementing some price changes with some of our new listings on the classified site and a complete list will be on our website as well.
Thank you past customers, and hopefully new ones for your support.
Sincerely, Michael Hicks

This is the unboxing only for the FEI LUN FX176C2 RTF GPS Drone With WiFi FPV. It is a very budget friendly RC Aircraft.

Unboxing Only - FEI LUN FX176C2 RTF GPS Drone With WiFi FPV (9 min 31 sec)

Here are the Pros and Cons:

Pros:
- Seems like a well thought out budget friendly RC GPS Drone
- The ability to fly with the App with Wifi FPV and GPS is cool
- The price using the link with the coupon code included in the description is pretty impressive
- Because of the battery plug it comes with, it can be charged with a hobby grade charger
- The lights are nice and bright

Cons:
- Camera does not appear to be terrific
- The direction the FPV antenna was facing so far and that was an easy fix

Wing of choice is the Spirit 600mm from Banggood ..
This will be my 2nd Spirit 600 ..
The first was made more robustly with 9g servos and a larger motor ( 18 something ? )
And a heavy 3ch car Rx
And it needs some weight in the nose to balance things out .. ( Larger battery )

So hopefully the 2nd time around I can do it better :

This time I am going with the 1306 - 4000KV motor ( small - light )
Also a much smaller lighter ESC ( not sure 6A is enough - will see )
Also the servos this time will be 3.7g
And I will be using a Redcon 6ch Rx ( very light )
This will hopefully allow for the use of a small 2s like a 250 -300mAh battery ..
The goal on this build is to go light .. This should allow for much slower flight speed / glide better as well ..
I know , less weight will mean less tolerance to wind ..
But I really want a slow wing ( compact for easy deployment )

Got out again with my sloping buddies.
The day started in the 60"s but was in the low 40's by late afternoon when we made it to the hill 12 to 15 mph.

Here is my review with first flight of Ldarc KingKong Tiny 6X.

This time KingKong decided to use 7mm motors (like the old Tiny7) on 66mm frame (like the old Tiny 6): a perfect combination!
Speed and agility!

Finally after almost one year of FPV, even if I live near it, for the first time I went to fly one battery to the legendary "stargate" in Rome. I had a relaxing flight after the sunset, unfortunately with a lot of wind. Really exciting location...lot of adrenaline!

A pilot and passenger from Australia sustained only small cuts and bruises when an elk jumped and severed the tail rotor of their helicopter Monday evening near Currant Creek in Wasatch County. The pair was attempting to net the animal, Wasatch County Search and Rescue said on Facebook. Few details were immediately released, and it was not clear how the elk fared. First responders from Fruitland evaluated the two aboard the helicopter.

The main part of the Ka-3 fuselage frames are built. Still a lot of tedious filleting to do before the fun of detailing can begin.

Hi everyone,
In addition to go brushless, I replace original 3.7v motors with 7.4v 8520 motors and larger props. Can anyone show me threads about this idea or there is none before.
Mod steps:
1. Add a 2S balance charging female connector as the power source.
2. Remove 4 M+ lines from FC and connect all to 7.4v.


#有刷小四軸2S升級

1. 選擇機架搭配 8520 馬達/直驅槳(沒有減速) e.g. jxd515w, tiny8, Q100...

2. 選擇 silverware FC.
e.g. H8 mini, H67, B03, E011
其他不能刷 silverware 也可以 e.g. JJ1000
但不能調 PID

確認 所有 M+ 連接至 Vbat, 輸出級為 NMOS

3. 連接 2S 平衡充母座到飛控板,3.7v 給飛控,led,低電壓 都維持不變。

一般的 SOT23 NMOS 1A Vgs 8/10V, Vds 20V, 可以對應 2S PWM

4. 連接 4顆馬達 M+ 到平衡充母座 7.4v,M- 位置不變。或再增加一個2S母接頭 (e.g. JST)
