Right had a reply from Tim who distributes the SLU, he’s given me permission to reproduce his answers here.
Q. What is the current rating for the main motors? i.e. ElMod 20A per motor
A. I don't know what the current rating for the motors, but I was told that they will handle up to a promax 480 motor. I am not sure if that helps
TB – From what I could find the Promax 480 have a running current of 10A
Q. If I plan to use LiPo batteries (2cell 7.4v) does the unit have an auto shut off at 6v to protect the battery?
A. The SLU will work with LIPO batteries and has a voltage range between 6.5 and 12 V.
Q. Does the unit have any kind of physics/inertia facility to make the tank more realistic. Like the ElMod system?
A. As for inertia, there is none. But you do get very fine slow motor control, better than Tamiya
Q. Could you send an installation manual (for Heng Long tank) so I could have a look at what’s involved installation wise.
A. I can not send you the manual. It is under copywrite and I am only authorized to distribute it to those who make a purchase.
Q. What is the postage cost to the UK?
A. The last order I sent to the UK cost the buyer $60 CAD. This is unfortunate, but I have to fully insure every order including delivery confirmation.
TB – I’ve looked into this at
http://customs.hmrc.gov.uk/channelsPort ... e=document" onclick="window.open(this.href);return false;
And looks like there will be customs duty and VAT on the full value + postage.
I worked this out as $269CAN to £168 +4%, + 20% = £210 (obviously this is an approximation)
So bit more expensive but still a possibility.
