This guide is work in progress atm, check back in a week to see what’s new š
Brah, aka Shaka XL,Ā is aĀ 1.5m / 40in flying wing with flaps and ailerons thatĀ provides you with ultimate control over your RC Glider.
This model is a long-awaited development of the original Shaka Slope Wing.
It preserves the original shape while adding some features which did not exist in the previous design.
On the other side, the Brah inherits some design decisions of the original Shaka and there are some similarities in the build process as well.
We’ll refer to the original build guide as needed.
Elevons Only or Elevons & Flaps?
One of the main features of the Brah are the optional Flaps.
The wingspan and area of this flying wing is on the bigger side, so it likes to stay airborne, even when you need to land.
So we strongly recommend opting in for flaps, as these will help a lot on landings.
On the other side, the programming of a wing with flaps, also known as a full-house wing, maybe a challenge.
There are some basic recommendations that you can use to program your radio.
But if you don’t feel confident enough, get the hand of an experienced colleague, or just keep the control surfaces uncut and build it with Elevons only.
The Build Process
In Progress… Check back in a few weeks.
Radio Settings
Below, you will find an overview of an OpenTX/EdgeTX model setup used for the Brah.
This is just one of the options, that allow for quick adjustments at the field, especially while flying the Brah with flaps.
The main features of this model also includes:
- Motor disabling switch
- Using the throttle stick for both motor control and brakes on landing
- Dedicated endpoints and sub-trims for each servo
- Combined values of Pitch, Roll, and Brakes for each “pair” of flying surfaces
Here are some screenshots that will help you understand the mixes
