The Blue atlas motors are pretty good...But The are not as fast as a properly tuned/geared C2. The ONLY thing the atlas has over the C2 is the first 4-5 feet out of a corner but gives up a TON on every straight past 4-5 feet. The C2's are consistantly faster everywhere I have been so far.
The Epic Arcor 19 turn is a handwound motor with adjustable timing. The Epic 19t is a C2 based motor. The handwounds are for Oval classes since they allow the handwound adjustable timing motors. The C2's are fixed timing and the ONLY Roar legal 19 turn for Sedan and offroad.
The newest batch of IB3800's just came off the matchers. These are some of the best ones yet. Rutime is back up a bit, IR's are down and voltage is up a tad. There were NO cells with IR's fo 2.0. Very few 1.9's. Lots of 1.8's and 1.7's.
