    HI,
    Ive nearly finished all the major components of the Spitfire in PLA+ and am quite please, one thought though would it not be best to use PETG or ABS for the Motor mount instead of using annealed PLA, stronger more resistant to heat etc? Same goes for the Wheels exhaust stacks for the strength?

    Not sure on the motor mount but definatly not for the spinner. It ried printing the Zivko Edge spinner in PETG once. Centrifugal forces make it flex outwards once you spool up. It flexes too much.

    For the motor mount I’s suggest to use HTPLA and anneal that. Then it is harder and has better thermal properties than PETG.
