I did not know that Graupner still included that warning.
Yes, boiling them will reduce the chance of breakage. In the days when I flew U control diesel combat with Tornado 8x6 [ Bright yellow anybody else remember them?] if you got old stock that had been sitting in the shop for months this was essential if they were to survive a crash.
Yeah they still do.
So there is something to it after all.
Do you know if this is applicable to props from other manufacturers or strickly a Graupner thing?
