IBC

G'day folks.
i sent an email to the controlers@robowars (or what ever the adress is) asking some questions about the IBC, but i never got an answer and i was wondering, is that still a valid email adress (yes i got the adress right, it came from the robowars shop)

i probaly shou;d have posted that, ok here they are

is it a first time friendly thing (or is it really hard to get a grip on)
will it take 36mhz?
is it a good idea to go for the best on the first time? (or start low)
and is there anything i should know about this Speed Controler?

provided your radio will drive a normal servo it should drive the ibc (or any other speed controller)
ESC (Electronic Speed Controllers) are the best way of driving a bot. servo switching does work but its *much* harder to drive that way.
to use you connect the servo leads to your reciever, the motor and battery wires to the motors and battery then start driving. You may need to calibrate your radio somewhat.

"Will it take 36mhz" ?

It doesnt care about the frequency of the radio, *but*, it does care about a clean servo signal from the receiver.

A noisy servo signal caused by radio interference will give the IBC (and all failsafe equipped ESC's) a case of the jitters.

36Mhz FM sets are more prone to radio interference than most (only 29mhz AM is worse). 72/75Mhz sets are somewhat better, PCM sets are better again, and Spektrum 2.4ghz are almost interference-proof.

So, if you have a low-end 36mhz FM set that doesnt tolerate electrical noise (bots make lots of it) well, you may have some trouble unless you fidget about with shielding and external antennas

If you are using the weapon-relay output function, make sure you understand the "open collector" style outputs correct wiring. 12v relays only, one end of the relay coil to battery +, the other end of the coil to the "Aux 1 or Aux 2" pins on the connector.

Other than that, connect your radio (2 or 3 servo leads), battery (2 wires), motors (4 wires), and you're good to go. Be carefulwith your wiring, it does not have current limiting, so wiring errors will very likely cause bangs.

Use polarised connectors on everything so it cant be accidentally connected backwards, and make sure you have good quality connections to the battery power. Loose connections that vibrate under impact will likely cause the input voltage regulator to go boom.

End point adjustment is a problem on some old 36 kHz sets, servos can cope with a bit of extra travel but the IBC will failsafe as in glitch or stop.
