I had one bad experience when I used to run Nitro cars... the throttle was open and on full power and my battery died and the car went at 40 miles an hour directly into a concrete curb and ill I could do was watch and then run over to it and sigh with horrow.
thast exactly what I did.. if something got worne out of broke I replaced it with stonger/better parts.. however my ta06 was like striking golf.. I got a full ta06 pro kit second hand on ebay in mint condition for l20 pounds.. and ive probably spent 600 pounds easily so far.. I still intend to get the r sector chassis conversion and cs it too.. but so far im drifting it 50/50 and having lots of fun.. but the car even though all in all is at least 5 years old it looks like it is just out of the box.. if not better.
