Model Forum / Radio Controlled / Water Models / May 2004Dumas "Mr Darby"
Hello all! New to this NG, and have a question. I have a Mr Darby Tug, and am having a problem with the trans. and rec. linking up, I think. The Receiver is a Futaba FP R127DF 8 channel, and the Transmitter is a Futaba FP-T7UHF. All electronics are installed in the boat, but when I powered it up tonight, nothing happened. I have NO experience programming a Transmitter. This Trans. unit is for a Helicopter, but I thought it should work for the boat. The funny thing is when I hold the Trainer Toggle down for a few seconds and release it, the Props spin , and the Rudders move a little. After that, nothing. I appreciate all replies in advance. Thanxs, Scott first, are both trans and receiver the same frequency? and have the same crystal? second, the 7uaf trans is PCM capable, is the PCM/FM switch set to FM?, you state your using a FM Reciever. > Hello all!

Is this "switch" inside? Yes, BOTH units have the same Freq. Crystal. Thanxs for the reply, Scott > first, are both trans and receiver the same frequency? and have the same > crystal? [quoted text clipped - 17 lines] > > Thanxs, > > Scott If you are in the US, it may be a civil violation of various FCC statutes and admin rules to use an "air" (i.e. helicopter) frequency for a ground (boat or car/truck) application. Not sure if the same considerations apply in Canada (your ISP has a "tail" of .ca so you may be in Canada), but I suspect that there are parallel rules. More importantly, there is also the issue of possible danger to an air frequency operator in your vicinity if you are using the same frequency on a ground unit. You could inadvertently crash a chopper / plane. You, too, could have interference from a nearby air operation if you are on an air frequency, but I doubt that would crash / destroy your boat. Maroon it, maybe, but not crash / destroy it. Whereas signals from your transmitter could crash a chopper or plane. I urge you to shift crystals so that your transmitter and receiver are on a ground frequency. -- Jim McLaughlin Please don't just hit the reply key.
