We recently added a new flight controller to our catalog, and building with this flight controller is really simple and quick. Gone are the day you have to solder 4 differnt escs, and solder the signal cables, etc. The F405 Stack will remove that step for you, thus eliminating precious time taken to build your FPV quadcopter.

Here is a sample order list for a 5in quadcopter drone kit. These are top notch components for a fraction of the price of a BNF unit you can get on the market.

Frame – BoltRC Lambda
Flight controller and ESC Stack – Mamba F405
Motors – MRS Komets 2306 2450KV
Canera – Caddx SDR 2
VTX – Matek HV Vtx with Smart Audio
Receiver – Frsky rXsr or TBS Crossfire Nano RX
Props – HQProps 5 x 4.3 x 3

Connecting Motors to the ESCs

Let’s begin by identifying where the front of the Flight controller should be facing. All flight controllers have a little arrow to show you where the front is, and in this case, the arrow is situated just above the F4 chip, in the middle of the board.
Once you identify the front , the motors are as follows, motor 1 ( lower right) , motor 2 (upper right), motor 3 (lower lef) and motor 4 (upper right).

Last but not least here is the wiring diagram for the Mamba F405 Flight controller. Please double check and make sure no shorts exists. Best way to do is to create a smokestopper.

BLHeli_32 is the 3rd generation of BLHeli firmware after BLHeli and BLHeli_S. BLHeli_32 runs on an ARM 32bit MCU, initially it will be on a Cortex-M0 running at 48MHz, but there are MCUs out there that can run a lot faster.


Here is a video made by Project Falcon, here he talks about BlHeli32

So what can the increased MCU speed do?

First of all, it can run input signals with lower latency at faster rates.
Dshot up to at least Dshot1200, and at rates up to at least 32kHz is now supported.


According to Oscar Liang, these are the future functionality of BlHeli32..

  • programmable PWM frequency of up to 48KHz
  • Auto-timing for higher efficiency and realiability
  • Current limiting (with built-in current sensor on ESC)
  • Adjustable “Brake on Stop” force
  • Improve direction change in Bidirectional mode
  • ESC Telemetry
  • Configuring from FC using DShot commands

Just received a package from DHL, and the fantastic Returner R5 Deadpool Motors have arrived.  We currently only stock the 2450kv version at the moment, I am trying to conserve your batteries.  This motor is going to give you the boost you need for racing for freestyle.

Be the first to get them , they are shipping now.

One youtube reviewer says this:

“Braking, not breaking. Nice balance of torque and efficiency I think. Motor felt really good, very responsive, me likey.”  – mooosestang

The New Presto Pegasus Symmetry R5 with integrated PDB and LEDs

Presto Pegasus was founded in 2014, with the aim of providing premium products for use in FPV drone racing.  This new frame from Presto Pegasus, the R5 is a 210mm sized quadcopter frame, designed with racing and freestyle in mind.  The R5 is designed to carry 5inch propellers, and has a symmetrical X configuration.

True X 210mm Quadcopter frame


According to Daniel he, designed this frame with the KISS Controller in mind, however this frame has hole locations for all the common sizes, including micro sized controllers, which is fast becoming very popular due to its size (weight advantage), and cost.  The frame will come with a 30×30, 20×20 mounting holes.

The frame is cut from high quality 3k carbon fiber.  Knowing Daniel only the best material is chosen, and rightly so, especially with the cutting edge nature of the way we crash our quads.

So here is a list of equipment you can pair this frame up with.


Motors – T-Motor F40II , F40 PRO and F60, TBS Steeles, Emax Whites

Flight Controller – Furious Radiance, KISS, Foxeer F303, Hyperlite F4

ESC – Flycolor Rapt0r BLS PRO 30A, Little Bee Spring 30A 

VTX – TBS unify PRo, Immersion Tramp

Camera – Foxeer Arrow V3 or Foxeer Monster V2

Antenna – TBS Stubby
