Servos

[Malakite]

Hi guys,

After looking through all of my gear, I have FOUR totally different servos, I wonder if you could help! They are as follows:-

Acoms IC AS-7

Acoms IC AS-12

Acoms IC AS-2

Acoms IC AS-17

Every single one is different n size (the smaller two by far at the AS-12 and AS-17's, of which the connectors appear to be the same). The other two have different sized connectors. I am totally unsure why I have these and what they could have been for? A couple are new so I must have had them from a packet of some sorts? I think moving forward I nned the servos to fit the standard 'TEU' speed controller that comes with the new Tamiya kits, so what servos would that be then? I need to buy a few more also for restore projects I would like to start, but I would need to know what receivers these would fit? Any ideas? I have lots of hand sets so it may be cheaper for me just to get a couple of servos and receivers instead of a whole handset package but not sure I'd need to do the sums I guess

Thanks guys, oh and all of my models are on the old frequency, I don't really know what i'd need to do to get the new frequency and how I would go about that - any ideas? Would it require a whole new set of radio gear and crystals or could I just pop in new crystals etc? Thanks

Greets,

from what i understand,all the servo`s you mention are the standard size and have the same physical fitting,the lowest numbered ones are earlyest.

The early ones,AS1 AS2, AS3 ect have larger plugs on the ends of the wires,they fit early receivers,the servo bodys get smaller [same mounts] the later they get,this is due to smaller motors and internal components being able to do the same job.

The plugs change slightly over the years but all work exactly the same,obviously you will struggle to get an early servo plug to fit into a later receiver because the plugs are phsically to big to go into the later receivers,but if you solder new modern wires/plugs onto old servos,or trim the plugs down they will still work fine.

The idea is so the plugs can only go in one way into the receiver to avoid blowing them up.

The old receivers are mainly all 27MHz but the servos will work with 40MHz and 2.4 GHz receivers,so you can use any frequency or receiver with the same servos.

The crystals determine the frequency used but you can not use 27MHz crystals in a 40MHz receiver etc stick to 27MHz receivers and 27MHz crystals.

40MHz crystals for 40MHz recievers etc etc.

All the servos will work with any MHz or GHz systems[in general]

Hi Twisty,

thanks SO MUCH for that helpful insight OK so any tips when looking for receivers that will fit these? i.e. what makes/models do I need to be looking out for?
