@Rajathv8
Thx a ton for ur feedback , it's appreciated  ....it has surely added to my knowledge
Okay 1st thing 1st I will buy a brushless motor as adviced by you 
Secondly I have a budget of around 20k ....including all battery +charger etc..
Not much for buying a rc in India but I will be getting one from Singapore and it's pretty cheap out there if u get a gud deal,  ..I hope I do
3)hpi Is my 1st preference ,traxxas comes second any suggestions for any other brands or models
Truly speaking I haven't even considered traxxas
Not sure which brand,car ,battery to call for
In terms of battery I will start with nimh only but not sure how much mah
truly love the response of people in this forum ....it's an honour to be part of this forum ....

No offense but please be careful while buying what u want .. as we don't make the right choices all the time specially in the begining .. buy a proven platform .. which has support and thunder tiger is good for one month and then its boring forever .. ul be repairing the car half the time .. this is from my personal experience tt fans do not take offense ..
Scale also gives u an aproximate of the vehicle dimensions btw .. lol

@ Pravesh None taken rather I am more than happy to hear from u guys and learn frm ur mistakes and suggestions
Rather I have to be extra careful with wat I buy bcoz I won't have my second ride anytime soon. Not until I strt earning ...
U can give me any piece of advice u wish I am here to learn
Cheers !!!!

Another personal opinion - my TT is doing fine after all the bashing and it has never been boring

1/10 , 1/8 etc = approx dimensions.
424mm x 324mm x 150mm = EXACT dimensions.

Scale is relative. Dimensions are absolute.  

See the thing is tt is exciting .. very very exciting .. I have no words to say.. I too had a s50   
but if u have driven other cars in the market... then ul know why tt is boring .. it was the same for me too .. tt was very exciting because I drove only tt .. after I started going to the track and seeing others make me eat their dust and after driving many .. I know what is what .. after trying many vehicles out there and after going thru many vehicles I finally have seen where what stands .. tt is really exciting if your a newbie or non racer .. but once u start racing ul start repairing a lot and get fed up and buy a new car which means more money gone ..
i just want to help the guy make a good buy and not some junk. best is to invest once and for all and then slowly learn .

ps- exact dimesions only matter in big big races. i carried my s50 in my bike along with a jammin truggy, so transport shudnt be a problem .. u just need to use the head on how to. if we can buy expensive cars ..we can surely stitch a nice bag of 800 rupees to carry them .. but some cases are surely exceptional ..

Good to know that you had experience with many cars/races, and that you can stitch a nice bag for Rs.800, however i stand by what i said

That's wat everyone says

according to your choice/options, i would suggest e firestorm, as u r going to use nimh, u ll not get full fun,but bigger maH the better run  time., rest your call
