if you just gonna play around, this small truck is not bad.. but the parts... I can said...real hard to find in some shop in KWS... unless you can ask some shop in there order for u.....for sure need to long waiting...
for off road.. I don't suggest to use 2 speed bcz it is hard to control when jumping and hard to control in track...
for .15 engine... for play is ok.. don't expect it is very fast... bcz it is .15 engine by Kyosho only...
for me, i will suggest to buy a real buggy from some taiwan brand name, like HN or HaoBo... RTR set around $2xxx, or China brand Nantai... they will have one new buggy will issue in April very soon.
