Stop piecing together tools one by one. The SENLO Model Engine Tool Kit brings together the bits, hex keys, wrenches and pliers that model engine building actually calls for, sized for the engines we sell, from the CISON LS-52 V8 to the RETROL HM-01 and TECHING DM229, all in one aluminum case.
No more ordering tools piece by piece and hoping the sizes match. Everything you need to assemble, tune and service an engine model comes in one case, from your first build to routine maintenance.
12 bits (hex H1.5–H5, Phillips PH1/PH2, slotted 4/5 mm, Torx T20/T25), a long-arm hex key set (H1.5–H10) and 5.5 / 7 / 8 mm wrenches. H1.5 fits the tiny grub screws on pulleys and gears, and H2.5 handles the M3 screws on cylinder heads and crankcases. A tool that fits grips cleanly, so screw heads stay crisp through many rounds of assembly.
The electric screwdriver adjusts from 0 to 6 N·m. Turn the torque ring down for small M1.6–M3 screws in aluminum blocks, and up for frames and bases. Need more force? Lock it and use it as a manual driver for up to 20 N·m. It's the same adjustable-torque screwdriver we sell on its own for $59.99.
Every bit fits the electric screwdriver. At 360 rpm with forward and reverse, it makes quick work of repeated tuning, shimming and gasket changes, and it's easy on your wrist after a long session. The 5.5 and 7 mm sockets speed up M3 and M4 nuts.
The black aluminum case has silver edging, metal corner guards, a secure latch and a carry handle. Foam-fitted slots hold each tool in place and show at a glance if anything is missing, from the workbench to the club meet.
