Hi gliggsy, :~
Firstly welcome to the Forum

. There is a wealth of information on here, you can always use the search facility which is located in the top right hand corner of the Forums banner or just ask a question and someone is bound to come along with an answer.
As far as a choice of a model Tank....in my Opinion there is Nothing to beat the
Glorious Tiger 1 !! .... It has a real presence about it, with a place in history that is
assured for as long as there are Tanks! It also has PLENTY of space inside to work on and to add parts into :~
Personally I would NOT spend my money on a Tamiya kit, for a lot of reasons apart from the fact that you actually have to assemble the whole thing sprue by sprue!
You can start out with a basic Heng Long and see how you like the hobby. If you do, then you can upgrade slowly as and when you feel like it / can afford it ...BUT....if you are ceratian that you will enjoy tanks then and are prepared to spend some money straight away then this is what I suggest as a really excellent combination to start with.
Heng Longs Tiger 1......and to start with, an Asiatam Hull from Welsh Dradon Models £59.74 at the moment, Steve also can supply a wide range of up-grade parts for all the varieties of tanks not just the Tiger..

This is the best hull and suspension system that money can buy, people have run them on this forum since they first came out and with tanks weighing in at nearly 15 Lbs with no problems at all !!
Metal Gearboxes with a 3-1 reduction as standard are a ' Must Have Item' as are metal sprockets and metal tracks. Starting as you are, from scratch I would suggest that you go straight for a 400 motor, these are the most powerful that can be fitted to the gearbox without some modification to the motor mount and pinion size. This shop is excellent both in price and in service

This is the motor reference..Graupner Speed 400 7.2V (1794) £6.43 each including vat and you will need 2 x 10 tooth pinion gears at a 48 pitch to mesh with the gearboxes correctly.
The Tiget Hull top and turret you can get from the member 'Forgebear' Dave although you could perhaps also ask Steve at Welsh dragon Models if he could help you if you buy the hull etc from him..
That is probably MORE than enough information to fire at you for one go....

....then you have to decide if you want to use an R/C unit that you already have or if you want to go with the Heng Long RX-18 unit which is good, so long as it has fan(s) to keep it cool, especially pulling larger motors.
Any other questions, please feel free to ask. :~
