Welcome to RCTA ss panzer crew hope we can help with any of your questions so just ask mate, good to see someone from Sydney, we have a small tank club in Canberra if you can make it down our way when we have a tank day. We are in the club section under Panzergruppe South.
We also like plenty of photos of your tanks so post away.
Is Heng Long a good brand... Well yes for the price you pay, like any thing usually dearer they are the better quality they are, HL are a toy tank but they are good I have about 10 of EM so far, there are plenty of upgrades for them and after spending a few dollars you can have a top of the range tank, or spend nothing and leave them as they are. They will break down a fair bit but you will lean a lot about the mechanics and repairing them
Cheers
