All members should note that SMFC Rule 17 requires that all IC models meet the BMFA noise criterion of less than 82db. Owners of IC models should submit their models for noise checks with Richard Golding as soon as practicable. Richard carries his measuring equipment with him when he visits the airfield.
Noise checks should be carried out within suitable conditions. The wind should be less than F2 (<7mph)and ambient noise must be at a minimum. (Birdsong, conversation, traffic, other models running or flying) The checks should be carried out over grass and away from sound reflecting buildings and vehicles.
A noise check before you may fly an IC aircraft is not necessary because the conditions for scientific measurement may not be suitable for some time.
