i finally got a chance to break in my new warhead, and this thing is awsome. as usual, the break in was tedious. the first start was very hard but once i did get it started it never died once. three days later, i had finished the 5 tank break in and started tuning it for performance. once that was done, a quick adjustment on the tranny and it was time to have some fun. the super tiger .27 puts out plenty of power that is transfered to the ground well. the 2 speed tranny worked flawlessly and it always shifted reliably into second gear. also, the reversing unit worked very well. the 220 cc fuel tank provides long runtimes so i had lots of bashing time in the front yard.
