Afternoon all,
My lad has a ride on merc but the remote has stopped working. I don’t know anything about electronics but have opened up the remote and no obvious loose wires. Battery brand new. Any easy fix options? Failing that any replacement options? Do I just need to match the 40.680MHz freq?
Thanks all

Have you checked for loose wires on the bit of the vehicle which receives the signal? That's the bit that has been bouncing around.
Ohh that’s a bloody sensible idea. However the red led on the remote does flicker so think it’s definitely a remote issue.
Thanks anyway
Will a 40MHz controller work with my 40.680MHz car?
Thanks
I think the unhelpful answer is: [i]it depends[/i].
As I understand it there is usually more to it than just frequency. They usually perform some kind of binding so that two controllers on the same frequency don't interfere.

Not normally on 40MHz - in fact I'm not sure that has ever been a thing on the 40MHz band. I'm fairly sure that's always relied on old-fashioned tech of different frequencies to avoid interference. Hence a 40.680MHz controller should work - the only likely issue is assignment of controls which might mean it doesn't wok the way you want, but I think it's all standardised.
If by 40MHz transmitter you mean a generic one for that band, then yes it should work, you'll just need a 40.680 crystal.
Ah fair enough aracer. I sit corrected. My only experience is with more modern stuff like quadcopters that do a pairing handshake, but they are on a different band.
Great thanks
Yeah most (all?) modern stuff is on 2.4GHz where various spread spectrum coded schemes are used and as you say you do pairing with Tx and Rx. With RC flying it used to be a thing to have a frequency selection board to make sure you weren't clashing with somebody else - modulation is just basic FM I think. I presume a similar thing for ground based stuff.
This is a pretty basic ride on kids car so guessing it’s not sophisticated enough for T:R pairing.
