ok if doing the suggested do you need am servos for a am transmitter and do they need to be the same make?

i have tried it with some which arent as above and nothing so..

what would be the next stage after this if it does work?

In general a servo is a servo ..... the freq is irrelevant.

OR ......If you like ......any servo should have worked in your setup.

So .....The problem seems to be that you are not getting a signal from the reciever to the Electronize speedos.
This fits in nicely with your motors initially jumping around ......then failsafing to neutral.

OK..It could be either a fault with the transmitter OR reciever.

Questions

Did the bot work properly ......then stop ..... or has it never worked?

Is your transmitter showing full charge / battery.
Is your reciever battery fully charged.

Have you got any spare crystals for the Transmitter and Reciever?

Another thing that everyone has done on here at some point and havnt worked out for a long time...
Are you sure youve plugged the leads from the servo/speedos in the the right way around?

If not the battery that your plugging into the receiver may not be charged, may be a loose connection in the battery (very common in receiver packs so check that voltage first. If your getting a voltage through the battery, and its plugged in the battery pins, the correct way around and all other leads in the correct way around then you have a problem with your tx/rx. If thats the case, then check with a differentset of crystals, then can stop working if theyve had a knock.

ok answers to the questions
Woodys

yes it did work before at wigan in a way, but since then it hasnt worked

the transmitter is showing full(green)

we are using the battery box thing that comes with the transmitter, and using 4 AA

yes we do have a spare transmitter reciever crystals because we have another transmitter setup exactly like this one

Grant

I will checkthe connections but im 99% sure i have checked them, and they were ok

i will try the different crystals, and the leads and post later

perhaps i have missed something but the first thing i would do,
test crystals,then reciever, battery,servos,transmitter, with your other transmitter setup and you will eliminate the problem straight away.

Running problems

Check that you have the CORRECT PAIR of crystals .....I.E. The same number on both the Receiver and Transmitter crystal in the same bot.
AND/OR ...As suggested ..If you have an alternative working Receiver / Transmitter combo .....swap that into your non working bot.

If all else fails, bring it to Magna anyway, as long as the speedos are OK, I have spare RX, & Crystals, etc,Ill bring, Im sure some of the others have spare bits also, as the saying goes we can rebuild it!!, even on the day.
