Magnificent! And your statement about 1/35 scale models being too small for your eyesight and manual dexterity really hit home with me.
Please forgive me if I ask an extremely rude question, and bear in mind that I only do so as a complete newcomer to 1/16 scale. What would a project like this cost --- not merely the kit itself, but all the aesthetic upgrades you list in your first post here?
I trust many other Armorama patrons will understand when I say that my spouse, truly the light of my life, may take some gentle convincing that this is a reasonable expenditure on my part!
I was lucky with mine, I bought the tank second hand for £350 ($550). A brand new kit will set you back a lot more. Your best bet is to look on ebay for a cheap one, they come up quite often. If you want to go for full RC, you'll need the batteries, radio gear etc as Jeff said which will add up, but if you only want a static model, you can sell the electronics on and make most of your money back.
This is my 5th 1/16 scale Tamiya and to get them super-detailed to the level I like and add all the functions usually costs about £1500-2000 ($2350-3100)depending on the price of the kit and which tank it is. I do tend to add a lot of upgrade parts though and a ton of photo-etch which all bump up the price, the metal tracks alone can increase the price drastically! Check out the site ETO Armor to give you an indea of upgrade prices.
A tank like a Tiger has a lot more upgrade parts, but the Panzer IV only has a few available. I do have a Tiger to do next, and I plan to go whole hog on it.
Thanks for the comments, I do love these large scale builds, and the Jagdpanther has been on my 'must build' list for a while.
You'll see a whole lot more posts coming soon!
