JC Racing Products have introduced their new liner removal tool for the use with .21 nitro engines. It features an outer tube which has a diameter of 15.80 mm with a sprung latch which locates in the exhaust port. When offered into the liner, a second plunger is inserted down the centre of the outer tube to positively hold the latch in a closed position – this helps with removal of liners which can become tight over time compared to when the engine is new from oil residue. The tool has been tested on bores from 16.20mm to 16.50mm and will remove liners which are smaller or greater than these sizes on engines such as Sirio, O.S., Werks, Reds Racing and similar. The tool is 3-D-printed in a high quality fibre impregnated nylon giving it excellent mechanical strength and durability.
