I am looking at buying a heng long KV-1 and have a few questions -
1) I can't find an IR version for sale in the UK - could you recommend a vendor that sells them.
2) I was going to install the taigen 4:1 steel gears - are these the best option? With the standard plastic hull do the long shafts work with both the metal and plastic sprockets?
3)metal / plastic tracks - can you run the plastic ones with slack to get the track droop (like the characteristic KV look) and will they be ok out in the backyard or would I need to look at the more weighty metal tracks.
I thought about the "full metal option" but as I like tinkering I thought I would work on improving the plastic chassis instead - plus its cheaper

Cheers
Guy
