I've got two 7955's in my Truggy, and a third in my box as a spare. Judging by the performance so far, I'm not likely to need the extra one.
More than enough torque, fast enough that I have to use a ton of expo in my radio, and dang near bullet proof. Definitely can't go wrong with them....oh, and the ability to run unregulated Lipo is just icing on the cake.
