Model Forum / Radio Controlled / Land Models / October 2005Basic RC question regarding frequencies...
This summer I bought a cheap RC boat. However, the remote controller (27Mhz) broke and since I only had a 49mhz truck, I could not interchange the controller between the 2 RC devices. I just purchased another RC truck with a 27mhz controller. I figured this would also me to have 1 controller for 2 devices ( the boat and the truck). However, I am surprised to see that the boat does not seem to work with the RC truck remote controller. Shouldn't all 27mhz devices work with this new 27mhz controller??

You probably have a different frequency in your boat's receiver than you have in your transmitter. Yank the crystal from your truck's rx and put it in the boat's rx.................this should do the trick. If your tx is broadcasting on 26.995Mhz and your rx is listening on 27.995Mhz they'll never hear eachother. Doc Well 27 has more than that IE 27.095 27.105 > This summer I bought a cheap RC boat.

I just assumed that 27mhz was...27mhz... How stupid of me... Now, could I also remove the crystal from the 49mhz truck and put in the boat? Of course, I first have to figure out what is the "crystal" and what it looks like... Andre >This summer I bought a cheap RC boat.

A 49Mhz crystal will not work in a 27Mhz transmitter or receiver. What brand and model are you running? The only stuff I've seen on 49Mhz are the cheap "toys" they sell at Wal-Mart and the like, so I'm assuming all of your vehix are the cheap ones, in which case they will not even have crystals.

I could tell from the original post. |
