This is a mount for the landing wheel in a Flyzone Calypso.
To use the original wheel and axle shaft, the hole may need to be drilled out a little.
If possible, replace the original axle with a steel one.
Depending on the foam wheel, the mount may need to be widened by 2mm or so.
Some trimming of the foam body is needed to fit this mount, then it can be held in with hot glue.
This will fix the loose and wobbly landing wheel that is common on this glider.
