I would opt for the lc racing emb truggy, that's just my opinion, they can be bought from Germany, i recently made one from spare parts i had from the buggy just added the longer chassis and bought the body from Germany, the rtr lc truggy has a decent motor in it to start with so no heat issuse but its down to individual choice, plenty have bought losi mini 8t and swapped motors and electrics but again restricted for the size of motor which i believe to be too small in stock form.
