super, merci pour le tuyau... thanks for the info. ... and i was wondering if you thought it was right that i bought a 41 mhz radio pack with a 72 mhz receiver ? on the receiver the frequency is written 41.000 and the quartz is a 41.000. do you think the length is still 1067mm ? it seems to me that the antenna was shorter than that before... but i dont know very much about those things...
