Robitronic Power Unit .28 Big Block motor

Robitronic’s new .28 size power unit is a 4,6ccm big block engine for 1/8th scale buggies, truggies and monster trucks. Its oversized cylinder head provides plenty of cooling for even the hottest races. The dual-support conrod, the robust ABC construction and the 3-needle composite carburetor are only some of this engines top features. For easy factory-settings, the needles are specially designed to mount flush with the carburetor.
