As a very ancient but recent member I joined hoping for some informed help.
I recently re-discovered a model car which I bought for my youngest son circa 30 years ago but despite visiting a model
seller it refuses to co-operate.
It is all hard wired, has one servo driving the rear wheels via a rechargeable Tamiya 1200mAh battery( which needs replacing) and another operating the front wheels via 4 off AA batteries. the seller said that the radio receiver Acoms ARC-227 was not receiving a signal and did not know if it could be replaced.
However with a more informed friend than myself (not difficult) we think it is more likely to be the ICAS 5S servo driving the front wheels because the rear servo reacts to signal.
We think the controller still works but not absolutely sure
How can we test to identify the problem, and where can we buy replacement parts?
Any assistance would be most appreciated.
Thanks

All assistance would be appreciated

Swap the servos round to see if the fault lays with the servo or transmitter or receiver. Plug the good one into the port for the non working one. If the servo works in the other socket, it is a servo fault. You can still get 27mhz receivers from Futaba, but not transmitters any more. Chances are you have old style plugs in the model which wont fit more modern equipment...and it may be an Acoms Techniplus, but that's just a guess %)

As a bit of an RC car Geek, any chance of some pics?

I may be wrong but have we got the correct terminology here. The front servo will only steer the front wheels I presume. The rear "servo" may be the motor that provides the drive. If it is 4-wheel drive I may be wrong. A picture would help.

I suspect that the rear servo operates a mechanical speed controller - 'course I could be wrong - pic please....

no reason why the old servos and receiver cannot be swapped out for modern ones
Hell, you could even ditch the mechanical speed controller and servo for and electronic one.
Looking forward to seeing a few pics.
