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
GPM Precision Upgrade for ARRMA MOJAVE GROM Drivetrain
This transmission kit is engineered for hobbyists seeking a durable driveline upgrade on the ARRMA MOJAVE GROM. CVD drive shafts are machined from 4140 carbon steel to provide enhanced torsional stiffness and abrasion resistance. Hex adapters are aerospace grade 7075-T6 aluminium for secure, low tolerance wheel mounting. The kit replaces fragile dog bone and plastic wheel shafts with CNC machined steel wheel stub axles for higher load capacity. Pins have been increased from 1.5mm to 2mm to reduce failure points. Reinforced cup joints are included for reliable differential connection and versatile fitment.
