Whoopee is probably the best thing I have created with my 3D printer so far :) It flies really really well indoor, and it’s not hard to build.

I love this build because all the parts are so widely available, everyone should be able to get them quite easily.

Whoopee Micro Quad Build Parts List

• FC: Micro Scisky
• RX: SRP8 PPM Receiver
• VTX: FX798T
• Motors: Banggood 0820 Brushed Motors
• Battery: 380mAh 1S LiPo
• Propellers: Ladybird
• Frame: Whoopee Micro

With the Scisky board, you can run Spektrum radio with out of the box. With the external PPM RX hack, you can use Frsky TX (such as Taranis) too.

While the Banggood motors work fine, I would recommend getting some Angry Beez motors, or MMW Dark Edition motors for more power.

For more micro quad part options, check out this parts list.

Soldering Motors on FC

First thing first, measure if your motor wires are long enough to reach the FC from motor mounts. Mine aren’t, so I had to extend them.

Now insert the motors in the mounts, put a zip tie around the mount. Then put a heatshrink tube at the lower part of the motor to protect the motor wires. It also works as landing gear :)

Flight Controller Installation

I use double sided foam tape to stick the scisky on the plate. You can also consider to fix the FC more securely on the plate with a zip tie.

Install the FC plate on the main body, make sure it’s well levelled and all the holes at the corners match. Then put some zip ties through the 4 holes.

I made myself a little connector to get 5V from the FC to power my FPV setup. The Scisky has a 500mA rated regulator (if I remember correctly). However I still recommend powering your VTX with battery directly if possible.

VTX/Camera Mount

Now install the VTX mount.

And your FPV Combo Setup, followed by the antenna protector.

Finishing touch

Double sided Taped the RX on the frame.

Using both Velcro and rubber bands to hold the battery in place :)

How I plug in the USB cable – Cleanflight Configurator GUI

You might have your own way, but I normally just lift the FC a bit and able to plug in the USB cable this way.

Another Whoopee is born :)

The build weights 44.5g without battery. Flight time with one of those 380mAh battery I got from banggood is about 2:30 to 3 mins. I probalby won’t use any bigger batteries, it doesn’t feel good as it gets too heavy.

Cleanflight Settings (02/08/2016)

I will always come back and update when I find better settings. If you have any good settings please let me know :)

First update your Cleanflight to the latest version.

set motor_pwm_rate = 32000 set min_throttle = 1000 set max_throttle = 2000 set min_command = 1000 set acc_cut_hz = 15 set deadband = 4 set yaw_deadband = 4 set dterm_cut_hz = 20

PID and Rates

set pid_controller = MWREWRITE set p_pitch = 39 set i_pitch = 32 set d_pitch = 25 set p_roll = 38 set i_roll = 29 set d_roll = 26 set p_yaw = 90 set i_yaw = 50 set d_yaw = 8 set p_level = 20 set i_level = 7 set d_level = 35 set rc_rate = 40 set rc_expo = 36 set rc_yaw_expo = 8 set thr_mid = 63 set thr_expo = 20 set roll_rate = 35 set pitch_rate = 35 set yaw_rate = 43 set tpa_rate = 30 set tpa_breakpoint = 1650

It flies really good with horizon mode too, so leave ACC on.
