JConcepts adds to the list of performance parts for the EB410 with a carbon fibre upper deck. The new upper deck offsets the position of the fan mount which allows several benefits. The first is the ability to use the JConcepts F2 body as the new carbon fibre part shifts the fan over to clear the low-profile cab of the body. The secondary benefit realised after testing the new upper deck is the ability to use a taller fan. This is a benefit not exclusive to the JConcepts body but to all low-roof body shell types because taller fans are typically more powerful and move more air. Another positive to the JConcepts carbon fibre upper deck is the slight position change of the fan allows some lower power fans to work better without the force of the motor magnets affecting the fan, bearings or rotation.
