Car Freq Mod?
 

I'm looking to run 3 ZZs at the same time. Has anyone been able to change the Freq in the chasis to something other than 49 or 27?

Can someone help me understand what to change in the chasis to get different Freqs? I see the crystal in the controller, but don't see the obvious item in the chasis to change.

What I would really like to do is to mod it to accept a crystal socket in both, then use the Xmod crystal sets.

Thanks in advance!

FCC legal stuff says you can only run 27 and 49 for landbased RC craft. Blah blah blah, I didn't tell you anything, don't to anything I say, blah blah blah.

Ok, so probably the best way to be able to run 3 cars at once is to get 3 of the ZZ-SE models, you can run 6 of them at once, and they're all on the 27mhz band, so you can also run one of the base models on 49mhz.

You could always get a "bullet clone", they're knockoff Bit Char-G / Microsizers, and most of them are on the illegal freqs. I think I've gotten some on like 27, 35, 40, 45 mhz... Component or Board swap pretty easy if you're handy with an iron.

These cars aren't quite good enough to have a crystal in the RX, but that's ok the weight would slow them down anyway. They use a tuning coil, it's a ferrous plug that you screw in/out of a plastic thing supporting a coil. That changes the ressonant freq of the RX; it works decently, but it's not selective enough to run like a Tx on 27mhz ch.1 along side another TX on 27mhz ch.7 because this type RX is not very selective. The tuning coil is generally white, and the top is filled with a soft wax.

Let me know if you like any of those options, and I'll try go into more detail on it. I'm tired of typing

Alright, now let's see some pics of your P-body. :eek:

Thanks for the info! I guess then the I may try to swap a new crystal into the TX and tweak the coil. Do you know how much range the coil has? Say I put a 50Mhz TX in... would you think I could adjust the coil to match?

Thanks again.

I'm not really sure about that, I'd say just swap coils with the board off your donor car, then just adjust the ferrous plug on RX (with non-metallic adjuster) for maximum range from the TX.
