hi , these are a cheap truck but a very good basher i have had one for a couple of years now , they are copy of the tamiya tl01 chassie , the gearing on these trucks are very high , lots of guys i know have burnt up motors in these truck,s so brushless is your best bet , only problem is the pinion the motors that use there pinion size are 3 mm and most good brushless motors are 5 mm , i heard the guy that owns this site makes a bore reducer , not sure ,but you would need this in order to install a good brushless system .. may be the other guys on here have a link or info on this bore reducer , my bonzer has had it electronics taken out and replaced with better grade esc servo and receiver, but i was also thinking about brushless the sock motor is a 560 , low has lots of torque but not much rpm i think its around 11,000. so not very fast to say the least .here are some pics of the bonzer you can see i have installed bigger monster truck wheels ...
