Hi Mike
It would be hard to give specifics as each tank and more importantly tankers budget/skills are widely different. Expectations too....
If you have a high degree of R/C knowledge and some engineering skills then you might consider brushless motors for any slight improvement they may offer. But you will probably have to find/make your self some custom gear boxes and look for a specialised control board.
Personally because of the wide rage of products already available for brushed motor setups it is easier for now to stick with them. But again that's just my opinion.
Regardless, brushed or brushless, M1 or Tiger you need to have a decent programmable Radio for your tank. That is why here at RCTA you will see so much devoted to the 9X series and Taranis. You simply need all the available switches and to be able to program custom limits for each of your tanks. If you think you Tiger is going too fast it is a simple matter of adjusting down the throttle on your radio. You can do this no matter what control board you have.
Budget pretty much control what type of control board you go for and that will in turn influence your further choices.
Personal preference - do you want good sound or prefer to have smoke, IR or airsoft. In my case since I have many a Panzer III / IV I do away with the smoke altogether in preference of a decent speaker and or camera installation.
Level of knowledge/skill: Are you familiar with servos and do you wish to use them instead - What about gyros and 360 degree turret operation. All these factors come into play with choice of control board/radio & other extra items.
Personal Expectations: For me I prefer to keep it simple as the more things you want to change and the more complex the more likelihood of something not working. I prefer to be in "CONTROL" of my tank rather than have boards that "control the tank" for me. I prefer sound over smoke. I prefer to minimise the amount of metal on the tank to keep the weight at a reasonable level.
For a Tiger if I was doing up a Heng Long tank:
Get the Asiatam lower hull and metal tracks
Recoiling barrel if doing IR - airsoft for airsoft.
Visaton FRS speaker
Asp (why not they are pretty cheap for me
)
or El Mod
Turnigy 9XR Pro with tankER9XPro and 3 x 3 position switch mod
2 cell lipo as big as will fit into the hull with speaker
These gearboxes
