Differential thrust firmware for Santa quads !


The JJRC H67 Santa quad is a popular micro quadcopter.
Others with the same hardware are the Eachine E011C and the Boldclash B03 Pro....well except for the highly annoying speaker that plays Christmas carols.
Using Silverware, i've now got a system that emulates the old classic 2 channel flyers of 10 years ago. In this first case, the ITC Starscream, but any homemade or converted airframe that used to use just 2 motors for control can now be fitted with this mod.
The gyro is not active, for authenticity, though a version using it is certainly possible.

Video of functions:
Santa Rx to Airplane Diff Thrust (2 min 34 sec)


It brings 2.4Ghz reliable control (definitely not the case with some FM systems, evidenced by the condition of the F-22 in the pictures)
Binds right away, with no need to be on level ground
Differential thrust motor control
ZTT - Zero Throttle Turning
Proportional control of throttle, left + right
All safeties, such as LVC, out of range and will rebind in flight
It's the same thing as the old days, but has more control steps than most models and can also be fine tuned !

Silverware is the best thing since Playstation mod chips of the late 1990's !

What do you do ?
Follow the installation instructions in the first post of this thread by Silverxxx: https://www.rcgroups.com/forums/show...ource-firmware
Download the attached firmware and upload the 'bwhoop' file, found in the 'gcc' directory. All files attached, to show my edits.
You can now connect your 2 motors of any classic or scratchbuilt micro model, to the 2 rear pads on the Santa RX and fly like the old days

The idea now, is to build up a firmwares library, for different setups for micro airplanes, some with gyro assist, others without.
Aileron/rudder actuators, 4 motor diff thrust Lancaster's, servo outputs etc.
