Ordered flishrc cobra. Communication was great. Ordered larger batteries but they were the wrong size. Olly shipped the right batteries and gave a refund for the difference I paid. Couldn't ask for more. Thanks for the help with the order.

The seller knew I was after one and very kindly informed me when they came back into stock so now have a Flywing Bell 206. Fantastic bit of kit. Well worth the wait.

About this product
CNC-style 12x8mm hex adapter for LOSI LMT
This 12x8mm aluminium hex adapter is a precision replacement for the LOSI LMT 4WD solid axle monster truck, providing a tight mechanical interface between wheel hexes and axle pins using 6061-T6 alloy. The geometry preserves correct centring while minimising rotating mass.
The component employs a double-hole topology with an auxiliary 2.5mm locking hole for a retention pin or the correct screw. Supplied steel pins increase shear resistance and improve driveline reliability under high torque or competitive use.
Assembly is straightforward for experienced technicians: engage the adapter on the matching 12x8mm hex shaft, index the 2.5mm locking bore, and install the supplied pin or screw. Verify axial play and tighten fasteners to appropriate torque, applying thread-lock on steel-to-aluminium threaded joints to prevent loosening.
Packing includes
- Hex Adapter 12*8MM – 4pcs
- pins 2.5*12 – 4pcs
- Screw Pin 4*2.5*11.8 – 4pcs
Original Name / Part No:
LOS242053
Compatible Models
- LOSI-1/8 LMT 4WD SOLID AXLE MONSTER TRUCK-LOS04022
What tolerances should I expect on the 12x8mm fit?
The adapter is produced to tight machining tolerances for a press-fit or slip-fit on standard 12x8mm hex shafts. Use calibrated calipers to confirm shaft dimensions and trim minor burrs for optimal fit.
Which fastener type is preferred for the 2.5mm bore?
A hardened steel roll pin or the supplied screw pin offers robust shear resistance. For threaded options, select screws that clear through-holes without bottoming and apply medium thread-lock to prevent loosening.
How does 6061-T6 perform compared to stainless alternatives?
6061-T6 provides an excellent strength-to-weight ratio and is easier to machine, which is beneficial for rotating components. Stainless steel offers higher corrosion resistance but at a weight penalty and greater inertia. Write Product Review Please sign in your account before you can write any review.
