        Q: would they fit on the Happymodel Larva- X?
        A:
        Yesthis prop is compatible with the Happymodel Larva- X. However, two screws are required on each prop and the length may not be the same... The Genfan prop requires a pair of M2x7mm screws. As with most brushless motors, going with longer screws represents a risk of damaging the motor windings...
