going 4ws - current good tx

[RootBreaker]

ok so my ax10 has sat all winter.. been playing with the micros..
but need to get the ax10 back up and running where i want it..

so front axle had a lot of wobble and was going to buy aluminum parts but ended up getting axles from HillBillyCrawler (thanks man!) well just bought them so need to wait for them.

once i get them in I plan on swapping stuff around from my foff and ax10 as the foff isnt done..

so i will end up with 2 front axles with aluminum parts to put in the ax10 for 4ws.

so with that out of the way..

I want to run 4ws. I can run the Y adapter but do not want fulltime 4ws.

so my questions on TX/RX...
1. is the flysky gt3b or gt3c still the best choice currently?
2. i know they can be hacked and the sort.. but stock do they do 4ws, crab, etc without the hack?

so that should do for now...
