My .15 Rustler is very old and has now been through 2 engines (the 2nd died this weekend) and as My T-maxx is on the way i was considering getting a bigger engine this time toi make the rustler a bashing/speed truck. So my question is, what can i stick in there apart from a trx2.5(The bigger the better? Is all the easystart stuff compatible with other engines? Or am i facing pullstart? And lastly any links where to get the stinger exhaust/kit to a UK Address -Barnes
