Are you looking to buy JS-3 Tiger - Frame HDZero Compatible in Australia?
Initially starting life under the project name 'Tiger', the JS-3 began as an R&D platform for testing, & then after showing promise in the KAMA world cup, & then unmatched efficiency at the 2023 MultiGP International Open & Australian Drone Nationals, is ready for its official debut into the BMS Racing stable.
Note: TPU parts not included. They can be purchased separately in the JS-3 collection or STLs downloaded for free.
BMS Racing JS-3 Tiger:
The guiding principles of the design are as follows:
-Had to fit a complete, high power 5" powertrain & Foxeer HDZero system
-Lightweight & tight weight distribution
-Small motor to motor - no wasted material
This leaves us with an ultra lightweight machine, that maintains an impressive top speed, & outstanding cornering characteristics & uncompromised low-mid speed acceleration.
Some special highlights to note:
Fits Foxeer 60A slim & Foxeer HDZero VTX.
Primarily T300 Construction - Due to the small structure & prioritization of lightweight, this is the perfect material for the platform.
Simplified manufacturing process - This keeps frame costs down, especially over a fleet.
Shared parts & arm bolt pattern with JS-2 - This means there is the option to fit the frame out with the longer T700 arms of the JS-2, meaning for a mixed fleet you can utilise the benefits of both platforms, but have a single set of arms & arm braces that are cross compatible! Futher more based on our testing, we couldn't observe any measurable difference in top speed, track speed or track efficiency! There was an impact to straight line efficiency, but we currently believe this is due to the tune not being optimized for the longer JS-2 arms.
History of the JS-3 'Tiger'
Initially starting life under the project name 'Tiger', the JS-3 began as an R&D platform for testing the base principles of lightweight design as a single element of focus, & then served as a testing platform for the HDZero VTX. From there it became the lead testing platform for our efforts in the KAMA world cup, & after some further development competed in the MultiGP International Open, where it managed P2, & was the only platform that could do 3 laps, without HV charging & without destroying that battery at qualifying pace.
It was during this event that the airframe recieved a lot of attention & interest, & we decided to develop it further & see if it could work as a production frame in the BMS Racing stable.
While efforts moved towards adapting the frame to BMS quality & ease of use standards for production, the protoypes continued work in various aerodynamic studies, & with a little further development, we made the decision to bring it to the 2023 Australian Drone Nationals & as a final testing ground of our new design concepts. Here, the airframe managed TQ, First place & lays claim to the only machine at the Nationals that could run a four lap qualifying pace without HV charging, no special batteries, & landing at 3.7v per cell.
Other Specs/Stats:
- Weight (USA grams (no stack bolts, no TPU, including battery pad)): 48.98g
- Weight (Complete hardware + Battery pad, excluding TPU): 54.82g
- Weight (Complete hardware + Battery pad, including TPU): 59.88g
- Max Recorded Top speed: 208km/h with recommended parts + 51466 V2
- Other Top speed data: 183km/h with 51366 V3, 182km/h with Gemfan 5127
- Motor to Motor distance of 194.28mm
- True X Configuration & matching bolt pattern to JS-2.
Note: This is only the carbon & hardware for the frame. For proper assembly, additional TPU parts are required to complete the build. We have printing on demand available, but additionally all the parts are available on Thingiverse as a free STL download.
TPU sold through BMS Racing is made for the TBS Triumph Pro U.FL, Foxeer Predator Nano & in the case of the HDZero Version, the whoop lite board & 90FPS Camera with upgraded runcam lens. If you are using a different antenna, camera or lens, please contact us first to verify compatibility before you make a purchase. We will be producing more mounts & variants as required.
Kit Includes:
Everything needed to build the frame, less the TPU Parts and Electronics.
So Battery Pad, Battery Strap is included in the kit.
Recommended parts list (HDZero):
VTX Antenna: TBS Triumph pro (U.Fl for standard TPU)
VTX: HDZero Race V3 or Foxeer HDZero VTX
Camera: HDZero 90FPS Cam with lens upgrade
FC: Foxeer F7 or H7 FC 20x20 (note if 10v bec required - get the appropriate FC that can supply the right power output for your HDZero VTX depending on if you choose one with 5V or 10V requirement or you may choose to run a BEC instead)
ESC: Foxeer Reaper 60A Slim
Propeller: Gemfan 51366 V3, Gemfan 5127, Gemfan 51466 V2 or HQProp BMS
Gemfan v2 or v3? For most tracks the V3 is the better race prop / feel, however if you need to break the 200km mark then the V2
Motor: T-Motor BMS Raptor V2
Battery: Tattu R-Line V5 1400 or GNB 1300 or GNB 1500
RX: TBS Tracer, TBS Crossfire or Radiomaster ELRS
Recommended parts list (Analog):
