TWIST_DT
An aerobatic twin-motor park flyer with super-stable Angle mode.
TWIST_DT is a lightweight 600 mm 3D-printed park flyer that is approachable in Angle mode but still capable of tight loops, rolls, and lively Acro-mode flying. Its compact size, easy launch, and forgiving stabilised setup make it a strong first printed aircraft without limiting what it can do later.
Digital aircraft package
Includes the printable aircraft files, build guide, print guidance, CG information, and the full INAV configuration for the recommended setup. No physical parts are shipped.
Core specifications.
The main figures for the recommended TWIST_DT setup.
From slicer to first flight.
The TWIST_DT build guide brings the complete process together: print preparation, assembly, electronics installation, wiring, control setup, centre of gravity, and the main checks before flight. The supplied parts can be sliced in Bambu Studio, OrcaSlicer, or another capable FDM slicer.
Watch TWIST_DT fly.
See TWIST_DT move between calm stabilised flying and tighter aerobatics. Angle mode keeps the aircraft predictable and forgiving, while Acro mode opens up clean loops, rolls, and a much livelier small-field flying experience.
Low, close, and easy to keep in sight.
This third-person clip shows TWIST_DT flying tight circuits around the pilot at low level. Its compact span, low mass, and responsive twin-motor setup make it practical to fly in a small area while keeping the aircraft close enough to read clearly from the ground.
Forgiving when learning. Aerobatic when ready.
TWIST_DT combines an easy launch and super-stable Angle mode with enough control authority for tight loops and rolls. It can remain calm while a newer pilot builds confidence, then become a much more capable aircraft as those skills develop.
Easy to launch
Auto-launch helps take the stress out of the first few seconds, making TWIST_DT simple to get into the air.
Super-stable Angle mode
The included stabilised setup keeps the aircraft calm and predictable for relaxed flying, repeated circuits, and building confidence.
Properly aerobatic
Switch to Acro mode and TWIST_DT can perform tight loops and rolls without giving up its compact, easy-to-launch park-flyer format.
Light enough to play with the wind.
At roughly 187 g in the reference build, TWIST_DT is light enough to enjoy the wind instead of just fighting it. The twin motors and differential thrust give strong yaw authority, so you can turn into the wind, drift back, loop around, and keep playing in a small space.
- Football-pitch flying:
Designed for small-field park flying, not huge flying sites. - Grass landings:
The low weight makes gentle grass landings simple and forgiving. - Differential thrust:
Twin motors give strong yaw control and make wind play more fun. - Acro capable:
Rolls and loops are available when you want to switch out of stabilised flying. - Fast to print:
The parts can be printed in less than a day with normal back-and-forth printer work. - Quick assembly:
Once the electronics are prepared, the airframe can be put together in a morning.

Core electronics.
The TWIST_DT reference build is built around a lightweight 2S twin-motor setup. The build guide lists a 187 g reference total, including a 115 g printed airframe reference and approximately 73 g of rounded electronics, battery, and powertrain line items.
| Role | Recommended component | Qty | BOM mass |
|---|---|---|---|
| Battery | Explorer 750 mAh LiHV 2S 80C battery | 1 | 35 g |
| Flight controller | FlyingRC F4 Mini | 1 | 6 g |
| Motors | Flywoo ROBO 1003 14800KV | 2 | 7 g |
| Propellers | Gemfan 2015-2 | 2 | 1 g |
| ESC | Flywoo Goku BLS 20A 4S V3 4-in-1 ESC with LED | 1 | 5 g |
| BEC | iFlight micro step-down BEC module, 2-8S input to 5V / 12V output | 1 | 2 g |
| Servos | DSPOWER 4.3G S002M JR2.54 micro servos | 2 | 14 g |
| Receiver | RadioMaster RP1 ELRS | 1 | 3 g |
| Rounded electronics + battery + powertrain subtotal | 73 g | ||
This is the recommended electronics recipe from the TWIST_DT build guide. The power path is Battery → 4-in-1 ESC → BEC → Flight controller. Use ESC motor outputs 1 and 2 only, leave outputs 3 and 4 unused, and keep the props off while checking motor direction and output mapping. Required small hardware also includes one 3 / 1.5 mm carbon rod cut to 495 mm and six tiny cross-head self-tapping motor-mount screws. The BOM line items are rounded to whole grams, so subtotals may not exactly sum to the 187 g reference total. Substitutions can change CG, wiring, current draw, thrust, AUW, and whether the included INAV configuration still matches the aircraft cleanly.

TWIST_DT FAQ
Practical answers for builders comparing the aircraft or preparing a TWIST_DT build.
What is TWIST_DT?
TWIST_DT is a 600 mm twin-motor 3D-printed aerobatic park flyer with a forgiving INAV Angle-mode setup and capable Acro-mode handling.
Is TWIST_DT beginner friendly?
TWIST_DT is designed to be approachable: auto-launch and super-stable Angle mode reduce the workload for a newer pilot, while Acro mode provides room to progress into loops, rolls, and more dynamic flying.
How much does TWIST_DT weigh?
The TWIST_DT build guide lists a 187 g reference build total with rounded line-item masses.
What battery does TWIST_DT use?
TWIST_DT is designed around a lightweight 750 mAh 2S battery setup.
What electronics does TWIST_DT use?
The recommended TWIST_DT setup uses a FlyingRC F4 Mini flight controller, Flywoo Goku BLS 20A 4S V3 4-in-1 ESC with LED, two Flywoo ROBO 1003 14800KV motors, two Gemfan 2015-2 props, an iFlight micro step-down BEC, two DSPOWER 4.3G micro servos, a RadioMaster RP1 ELRS receiver, and an Explorer 750 mAh LiHV 2S 80C battery.
Does TWIST_DT include an INAV setup?
Yes. TWIST_DT includes a full INAV configuration file with the stabilised tune already set up. You still need to check CG, control directions, motor direction, failsafe, and flight modes before flying.
What do I get when I buy TWIST_DT?
You get the digital aircraft files, assembly guidance, print settings, CG guidance, and the included INAV configuration. No physical parts are included.
