I have a question or two I finally got some nitro I got blue thunder 20% LHS suggested it I love nitro now but my car is really sluggish feeling I either have to wait for a while for it to get going or I have to be at half throttle before it will start moving with any respect how can I make it start going sooner(or respond to throttle quicker[the engine revs but itsslow off the line])? What is a good reveiver pack or pack rating what about a good failsafe? could I tear down an old cheap 1400 pack and use that? Ive ran 3 tanks through the machine and I like it more then elec already working on them in cold isnt fun but driving em sure is! I think Im set for a while!
