It's here. The Repeat Robotics Mk4 "Mini" 16mm planetary brushless drive motor. Here's your chance to have all the speed you can handle in your antweight.  Mk4 is a large step forward from Mk3 (shipped thru October 2024).   Full upgrade info below.   Improvements: 1204 was changed to a 1106 for more stator volume and more outrunner clearance Output shaft is made from hardened 4130 steel, to improve lifetime and is integrated into the carrier plate, to improve durability. Output shaft is retained without the use of a circlip, eliminating the main failure mode and improving the durability Further changed the wire retention with stronger stator winding wires and mechanical clamping of the wires at the stator base. Gearbox baseplate is integrated into the brushless motor base, removing screws and additional points of failure. Specifications: 1104 3500kv custom brushless motor 2s-4s rated voltage 16mm, 28.5:1 all metal planetary gearbox 4mm “D” extra long output shaft (can be cut to length) 28.5:1 Drive with 3mm shaft – 24.7g ~24g weight with 4mm shaft (can lower the weight by cutting down the shaft and shortening the wires) Length: ~28mm body length for 28.5:1 ratio 10.5mm M2 Face mount hole pattern Comes ready for combat, just solder the motor leads to a brushless ESC and you’re on your way (Soldering iron required) If installing in a Viper or using the Flat Motor Mounts M2x4mm screws are ideal for mounting. This is not a drop in Viper upgrade, it requires new drive ESCs and a BEC.   Notes: These are brushless motors.  If your receiver was being powered from a BEC in your brushed drive you'll need to add a BEC.  These motors ship with bare leads, you'll need to solder them to the ESC or add your own connectors.  Performance: 7.4V input (2S) 909rpm 11.1V input (3S) 1363rpm 14.8v input (4S) 1818rpm Cad Link: https://grabcad.com/library/repeat-drive-mk4-1 Warning:These gearboxes can only accept ~2mm of face screw engagement. Using screws that are too long will result in damage.
