For use with the JP Hobby ER-120S Tricycle Full Set with Brakes (Sebart Avanti XS 1.9m or ARG Mistral 1.8m or EA Viper 2.0m)
After removing the very heavy brakes from the main landing gear wheels you can opt to replace the solenoid assembly with dummy covers. You will need a 5.1x10mm wheel collar snugly fit to the axle and then slide over the dummy cover aligning the small cutout with the collar screw so there is no clamping and the dummy runs smoothly and centered in the wheel hub.
Print in material to your liking as it is not a supporting structure, just aesthetic conformation to the original.
Best to iron the surfaces for a nice finish, unlike my photo here which was of a rapid prototype in cheap PLA :)
