Motor help

[Frost]

Hi there I popped down a few weeks ago, I have been spending money getting myself sorted to race again, firstly what I've baught, tc4 car, hobbywing 45a brushless esc, lipos, charger, programmer, servo, using my old transmitter, just need a motor now, what is everyone using? The limit(my speedo)for 2c lipos racing tc is 8.5 so I was thinking a 9.5!? Also the lipos I have baught weren't what I thawt, they are 2200 2s soft cells. A lot smaller than I thawt, think I saw a guy using them in his v12 the other week, but he was using a homemade holder( was this because they were soft cells) maby need to swap them for normal hard cased cells, have seen some 5500 2s 35c on eBay from china for £15 inc postage I know this is cheep but got to be worth a go????!!!! Any setup advise for an old tc4 would be great too, thanks andy
