ejtnt posted a topic in Trade ArchiveHello everybody, I am giving away an old acoms 2 channel FM pistol transmitter. It comes with a 27mhz crystal and a plastic geared servo. The Transmitter has throttle and steering trims, reverse switches, steering dual rate, uses 8 AA batteries and is missing the antenna. It still works fine. You can get a screw-on antenna for a few €. The controller comes with an acoms plastic gear servo. Unfortunately I do not have a receiver anymore. I am willing to give those away as long as the "buyer" takes care of the shipping costs which should be 5-7€ max.
Yonez posted a topic in All things electric...Hi, I received a brand new Tamiya FineSpec FM trasmitter with TRU-05 receiver yesterday. This has been pulled from a TT-01 Type-E XB set. Transmitter and receiver look perfectly fine and new, with no marks. The tape was even still on the battery door of the transmitter. However, I cannot get these to work. I've hooked up the receiver with a battery pack with 4 fresh batteries and put 8 fresh batteries in the transmitter. I use Panasonic Eneloop rechargables, and have verified that they're all fully charged. They're brand new and I just charged them. They work perfectly fine in an AM set I also received yesterday. I've tried connecting one or two servos of various brands to the receiver. I know that everything is connected correctly, because I've used Futaba-type connectors with the little guide tabs still on them to verify orientation. The battery pack has the tab. When I turn the system on (transmitter first) I only get interference type twitching from the servos. I have no control at all when I use the transmitter. However, if I wave the transmitter a bit, I get more interference. Both transmitter and receiver use the red channel 2 (27.045 MHz) crystals that came with the set. I've tried reseating both to ensure a good connection and antennas are fully extended of course. I've never had a FM radio system before. I'm leaning towards calling this a dud and returning it to the seller, but before I do I'd like to know if there are some more things I should try with an FM system before giving up on it.
