This is not to create a storm or anything.  I have the Hooben T-55 package which is a SLU made for the Hooben T-55.  I love it.   I battled with it at Danville in the regular "fun" matches and it performed fantastic.   Until all of this flair up over power bleed off I didn't realize this was a hot button issue.  I have the DBC in a Panther, and had to modify gearboxes, motors etc and add the new chip to keep it from becoming a pill box.   One major advantage the Tamiya has over all of the other systems is the 45 degree defense.  On the SLU, with it's IR Receiver setup it is impossible, even with designing some kind of cover, to have that feature.    The SLU uses 4 sensors positioned around the top.   The front and 2 sides are very close together hence, no defense possible.   That does mean a big advantage to the Tamiya.   At Danville, I use my Tamiya tanks for the "competitive scoring" events.    I love the SLU, and I find what Tim is saying about a new chip awesome.   I would buy the SLU without a second thought, if it was completely compatible.
