View Full Version : Tyco Rebound Transmitter hacks? Alternative CHEEP recommendations?

Okay, I know this is a toy and you guys are way past this, but the Tyco
Rebound is the ticket for my application due to it's ability to rollover and
keep going. Ultra precise inputs aren't necessary, but 200-300 foot range
is needed, vs the 65 foot (or so) that it has now.
I have basic soldering skills and some basic understanding of electronic
theory, but no idea of how to design cicuits, calculate needed values etc.
As an option, is there a cheap transmitter in 27 or 49 MHz bands that I
could use with a little set up time and no hacking?
Thanks!

It would be unlawful to do what you are proposing.

I'll sell you for $30 delivered a Hitec radio that they use for boats/cars.
Transmitter works great and the receiver is now getting serviced by Hitec.
It's also illegal, but I don't care what you do with it.

Hmmm.
I guess buying a cheap transmitter in 27 or 49 MHz bands would be illegal
too...
Thanks!

I doubt that buying another Tx on 49 MHz would do you any good, as max power
output would be the same, regardless of the shape of the gadget.
You might have better luck on 27 MHz, but the competition there can be
fearce.
I am assuming you are in the US.
What is this device anyway?

It's a three wheeled "car" that runs either right side up or upside down.
Big air filled front tire that can take some serious impact <I've read of
three-story drops> with nary a scratch. Go to:
http://www.amazon.com/exec/obidos/tg/detail/-/B000067Q3F/104-2877857-1506315?v=glance&s=toys&me=A3UN6WX5RRO2AG&vi=pictures&img=1#more-pictures
Could you recommend a cheap 27 mhz radio?
Thanks,

Ok Here is the story on a unit like this.
The cheap version of a 27 or 49 mHz transmitter has a limited range. It is made that way and it is suppose to stay that way.
I am in the process of attempting to increase the range of the Micro X- Tank and will let you know if I figure something out that works.
The problem with attempting to obtain another transmitter that is on the same frequency but with a greater range, is that it may be more of a hit and miss attempt to make it work.
I attempted to match my Traxxas E- Maxx transmitter to the frequency of the tank, it did not work.
The transmitter of both units have a IC ( intergrated circuit) that sends out a pulsed signal on the frequency given ( 27 or 49). The receiver in the unit is set to interput that pulsed frequency to produce a series of commands that move the vehicle.
You may be on the same frequency and the same channel of that frequency ( 27 has 6 operating channels), but unless the receiver is set to interput the pulsed out put of the tranmitter ( as they were set up at the factory) you will get either partial or no function at all.
You could potentially use a more powerful transmitter from a better piece of equipment like the Traxxas E-Maxx, but you would need to test it up against the Tyco unit to see if the pulse frequencies match. If they do not the only way to make it work would be to retune the receiver or to change out the IC of the transmitter. Either way it is not worth the time or effort to make this work.
You could place in a new receiver, but since the unit is constructed so that the circuit board acts as a speed control and a receiver you would have to remove that circuit board, replace it with a receiver and an ESC and then hope that the steering mechanism is not done by magnet so you can use a servo to steer.
There is another way to do this and that is the function that I am working on now to alter. If I find a way to do this ( not this weekend, but the weekend of the 26th) I will post it here.

How's it illegal? A "real" 75MHz transmitter would have the range
without having to make modifications to the transmitter. Wiring up the
receiver to the car may be a problem, but you can do anything you want
to a receiver as long as your modifications don't turn it into a
transmitter.

Thanks for the follow-up. I'm sure you've seen this, but...
http://members.aol.com/rchelicam/microszr/microszr.htm but this guy took a
"zip-zap" radio and hacked it to improve range from about 25' to over 200'.
Let me know what you discover?
TIA,
Matt
