  HGL RC F4 'Flytower'
Posted by: Tom BD Bad - 3 hours ago - Forum: Flight Controller - No Replies

Hey guys, I wanted to take a little time to bring details of a new supplier in the RC industry, to your attention, I haven't used any products from HGL RC, but the competitive price point of their first wave of products has peaked my interest...

Please note that the links contained in this post are affiliate links and as such will (at no extra cost to you) make me some small commission on your order or purchase. Thank you.

The first of the products from HGL RC that I  will be looking at are their F4 Flytower FC's the XJB F410 and the XJB F425. 
Photo's on the left are the 410 and the right are the 425.

These 2 products contain, for the most part, exactly the same hardware specs.

  • Processor: STM32F405RGT6 MCU
  • IMU: MPU6000 connected via SPI
  • Flash: 16MB
  • Firmware: BetaFlight OMNIBUSF4
  • Integrated OSD: yes
  • Power supply: 2 - 4S LiPo
  • BEC output: 5V 3A
  • PCB thickness: 1.2mm
  • Compatible receiver: SBUS, PPM, DSMX receivers etc.
  • Function: supports buzzer, LED strip, voltage monitoring, ESC programming, PID tuning etc.
  • Dimension: 25 x 25mm
  • Mounting hole spacing: 20mm 

The different specs for the ESC's make the differences in name explanatory - 
The XJB 410 has 10 Amp 4-in-1 ESC (burst current of 12A) and only supports 2s & 3s LiPo batteries.
the XJB 425 has 25 Amp 4-in-1 ESC (burst current of 30A) and supports 2s - 4s LiPo batteries.
Both have the same EFM8BB2 processor flashed with BLHeli_S 16.5 firmware.

Sadly Gearbest have neglected to confirm the product weight in the item descriptions and the only reference comes from the packaging info which states (for both 410 and 425) - 'product weight - 0.0080 kg' - the details given in the 'Product Dimension and Weight' section have been known to be inaccurate.

It's at this point that I should start talking about prices, but I seem to have come over all 'Top Gear!'

There is another newcomer, FuriBee, albeit not quite as new as HGL RC their new F4 Flytower option does require a mention.

The FuriBee Flytower Plus Mini F4 FC boasts a 128MB flash compared to the 16MB offered by HGL RC, an updated EFM8BB21F16G ESC processor with 'new-generation' 3-in-1 TPN2R703NL MOSFETs. The 20 Amp (25A 5 second burst) 
4-in-1 ESC comes pre-flashed with firmware from BLHeli_S, confirms support of DShot Protocols, and supports 2s-4s LiPo & LiHV batteries. 

All 3 are running BetaFlight Omnibus F4 Firmware for the FC with an MPU 6000 IMU, the FuriBee has the same STM32F405RGT6 processor as the XJB's and the same 20mm x 20mm mounting, but the BEC on the Furibee offers 5v at 1A where the XJB's BEC provides 5v with a 3A max. The RX compatibility is the same too, with support for SBUS, PPM and DSMX .

So back to the prices then, (correct at time of posting) 
HGL RC XJB 410 Flytower F4 - $43.28 (Ships between Jun 4 - Jun 10)
HGL RC XJB 425 Flytower F4 - $55.64 (Ships between Jun 4 - Jun 6)
FuriBee Flytower Plus Mini F4 - $60.26 (In-Stock)

  Keeping battery connected
Posted by: rryyyaann - 8 hours ago - Forum: LiPo Battery and Charger - Replies (5)

Any ideas on keeping an xt60 plug connected better on crashes.  Anytime I've had a harder crash my plug comes disconnected.  The battery itself is still strapped securely to the quad.  

This will be helpful for beacon if I get lost.

This video is a mix of flights from this weekend and last since I didn't get much footage this weekend due to the technical difficulties. Big thanks goes out to fftunes for introducing me to the artist on the soundtrack. 

Thread/Video title, reference to sound clip at the end of the video.

Music is a 3 song mix.
Artists: Tab & Anitek
Album: Sights & Sounds
Songs are: Harlem Sunset, The Cohen Method, and Mayor Special
Check them out of soundcloud: https://soundcloud.com/tab-anitek
Or better yet buy the album on amazon: https://www.amazon.com/Sights-Sounds-Tab...rds=anitek it's absolutely worth it!

  Short flight times for micro brushless
Posted by: CaCondor - Yesterday, 11:01 PM - Forum: Brushless Micro Quad - Replies (3)

Is this normal? I am only getting about 1.5 minutes on a 2 cell 500 mah battery. the motors are 1104 X 7500 kV

Here is a link to the video of the quad with description of frame and gear.

It's like I take off and fly around a few times and it's time to land. Maybe I should push my batteries more. I stop at 7.4 v for 2 cell and 11.4 for 3 cell

Maybe the motors are too big. I have good batteries.

  F450 APM 2.8 issue arming motors.
Posted by: flabombarda - Yesterday, 04:55 PM - Forum: Beginner Questions - Replies (2)

Hey guys, 

I´m working on a f450 build, and there is a problem I can figure out the cause.

- When I arm the motors and give throttle (any throttle, can be 5%, 30% or 100%) motors will spin always at full throttle, not respecting the % of the actual throttle given.

Steps taken:
- Radio calibration done, I can see throttle working just fine.
- ESC Calibration done also, in fact it´s weird because when I finish the calibration reducing the throttle to ZERO, then the motors work as expected, but if I unplug the battery and plug it back, then the same weird behavior is seen.

Here is a video:

Any idea ?

I was going through some of my video and noticed this nice steady almost aerial video platform like approach.  Pretty nice for a racing quad.
