The Official Armortek Forum - World leader in one sixth scale metal kits

Hello

I have an Old Tiger jn my workshop that im getting mobile for a customer and it has the old 4QD system. No movement at all. Any suggestions to the old boys.
Thanks
Lee.

Armortek leads in the receiver the wrong way round ?

Power or motor cables loose under the VTX black covers ?

Ignition lead broken ?

Inhibit Jumper fitted ?

Try swapping the VTX40s over - it will only work when #1 is attached, so any problem there and neither will work.

I've never done it but you should be able to wire a pot between the end three pins on the VTX40s to make sure they work separate from the DMR203.

Hello Adrian
All connections ok. Ive checked the signal from the RX to the DMR by using servos all ok. Jumpers all in correct rotation ie in Tank mode. Mains power to 4QD 24v. No movent at all.
He bought the motion pack about 10 year ago and has asked me to put it all together lol

PM sent to you
kind regards Kees

Sorry to hijack the thread, Adrian your not answering my emails to you mate! I need my amp board fixed or not ?
Kind regards Phil Woollard.

Regarding the 4qd problem Lee, if the units have been connected the wrong way round at some point, ie reverse polarity then they are toast!

Sorry Phil - I've seen them and it's on the todo list. I've swapped the chip out but still no joy. Still bogged down with house clearance at the moment.

Adrian.

Many thanks Adrian.

Regards Phil

Hi Lee

Did you get the problem solved?
I'm doing a horde reduction and came across some 4QD instruction paper work. DMR-203 and Pro-120
