Q: Should I get a Smoke and Sound Heng Long tank or is the regular one just as good?

A: The Smoke and Sound ( called S&S on the forum ) tanks come with more than just Smoke and Sound, it has different electronics that allows approx. 10 proportional speeds as opposed to 2 speeds in the non-smoke type and It also has better range, In short, pay the extra $10 for the S&S.
