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
Precision Engineered Differential for ARRMA KRATON 8S
The GPM MAKX0930S is supplied as a complete front and rear differential assembly for ARRMA KRATON 8S applications. It combines 20CrInTiH steel for the gear set with 7075 aluminium components to provide high material strength and consistent gear engagement. This unit replaces factory part number #ARA310937 and utilises a helical 9T/30T gear pairing with a 2.0mm module to maintain reliable torque transfer. Differential fluid is excluded from the kit and should be fitted separately; 100k cSt silicone oil is recommended for proper damping characteristics.
